Hepatic involvement in hereditary hemorrhagic telangiectasia: an unusual indication for liver transplantation. (1/57)

Hereditary hemorrhagic telangiectasia (HHT) is a vascular disease with multiple organ manifestations. Severe hepatic involvement is an unusal indication for liver transplantation. We report on a 39-year-old woman diagnosed with HHT and decompensation of the disease during her second pregnancy. After delivery, hemobilia occurred, followed by severe therapy-resistant cholangitis and progressive liver dysfunction. Because of progressive loss of liver function, orthotopic liver transplantation needed to be performed. The various aspects of liver involvement in Osler's disease, diagnosis, and therapy are discussed.  (+info)

Adenovirus is a key pathogen in hemorrhagic cystitis associated with bone marrow transplantation. (2/57)

Late-onset hemorrhagic cystitis (HC) is a well-known complication of bone marrow transplantation (BMT) that is mainly attributed to infection with BK virus (BKV) and adenovirus (AdV). From 1986 through 1998, 282 patients underwent BMT, and 45 of them developed HC. Urine samples tested positive for AdV in 26 patients, of which 22 showed virus type 11. Among patients who underwent allogeneic BMT, logistic regression analysis revealed acute graft-versus-host disease (grade, > or = 2) to be the most significant predictive factor for HC (P < .0001). In addition, a total of 193 urine samples regularly obtained from 26 consecutive patients who underwent allogeneic BMT were examined for BKV, JC virus (JCV), and AdV by means of polymerase chain reaction. Of patients without HC, approximately 30% of the specimens tested positive for BKV (58 samples) and JCV (55 samples), whereas 5 (3%) tested positive for AdV. Of the 3 samples obtained from patients with HC, the numbers of positive results for BKV, JCV, and AdV were 3, 1, and 1, respectively; the numbers of positive results increased to 14 of 17, 9 of 17, and 10 of 17, respectively, when we added another 14 samples obtained from 14 patients with HC (P < .0001, P = .026, and P < .0001, respectively). In conclusion, there was significant correlation between AdV and HC in the patients we studied.  (+info)

Hepatic artery angiography and embolization for hemobilia after hepatobiliary surgery. (3/57)

OBJECTIVE: To evaluate the effectiveness of hepatic angiography and embolization in the diagnosis and treatment of hemobilia after hepatobiliary surgery. METHODS: Nine patients had upper gastrointestinal bleeding 7 days to 3 months after surgery. They underwent emergency hepatic artery angiography and were treated by embolization using Gelfoam particles only (8 patients) and Gelfoam particles plus microcoils (1 patient). RESULTS: Hepatic artery angiography revealed hepatic artery pseudoaneurysms in 3 patients, diffuse hemorrhage of the hepatic artery branches in 3, right hepatic artery-bile duct fistulas in 2, and hepatic artery-small intestine fistula in 1. Hemobilia was controlled with embolization in 7 patients, of whom 1 had recurrent bleeding 1 day after treatment. During the follow-up, 3 patients died of multiple organ dysfunction syndrome. Two patients whose hemorrhage could not be controlled due to technical reasons died several days later. CONCLUSION: When hemobilia after hepatobiliary surgery is suspected, patients should receive hepatic angiography as a first diagnostic procedure and be treated with minimally invasive procedure of selective embolization of the involved artery as soon as possible.  (+info)

Potentially fatal haemobilia due to inappropriate use of an expanding biliary stent. (4/57)

AIM: To highlight the fatal complication caused by expanding biliary stents and the importance of avoiding use of expanding stent in potentially curable diseases. METHODS: Arteriobiliary fistula is an uncommon cause of haemobilia. We describe a case of right hepatic artery pseudoaneurysm causing arteriobiliary fistula and presenting as severe malena and cholangitis, in a patient with a mesh metal biliary stent. The patient had lymphoma causing bile duct obstruction. RESULTS: Gastroduodenoscopy failed to establish the exact source of bleeding and hepatic artery angiography and selective embolisation of the pseudo aneurysm successfully controlled the bleeding. CONCLUSION: Bleeding from the pseudo aneurysm of the hepatic artery can be fatal. Mesh metal stents in biliary tree can cause this complication as demonstrated in this case. So mesh metal stent insertion should be avoided in potentially benign or in curable conditions. Difficulty in diagnosis and management is discussed along with the review of the literature.  (+info)

Life-threatening hemobilia caused by hepatic artery pseudoaneurysm: a rare complication of chronic cholangitis. (5/57)

Hemobilia is one of the causes of obscure gastrointestinal haemorrhage. Most cases of hemobilia are of iatrogenic or traumatic origin. Hemobilia caused by a hepatic artery pseudoaneurysm due to ascending cholangitis is very rare and its mechanism is unclear. We report a 74-year-old woman with a history of surgery for choledocholithiasis 30 years ago, suffering from a protracted course of life-threatening gastrointestinal bleeding. A small intestines series and endoscopic retrograde cholangiopancreatography revealed a chronic cholangitis with marked contrast reflux into the biliary tree. Angiography confirmed the bleeding from a pseudoaneurysm of the middle hepatic artery. Coil embolization achieved successful hemostasis. We discussed the mechanism and reviewed the literature.  (+info)

Laparoscopic management of traumatic hemorrhagic cholecystitis. (6/57)

BACKGROUND AND OBJECTIVES: Blunt trauma to the gallbladder is a rare entity, particularly when no other organ is injured. In isolated blunt traumatic injury to the gallbladder, treatment options vary depending on the specific injury. The types of blunt trauma injuries to the gallbladder and their appropriate management are discussed. In addition, a case successfully managed with minimally invasive techniques is presented. METHODS: A passenger admitted after a high-speed front-end motor vehicle crash was safely managed with laparoscopic surgery for a rare case of isolated gallbladder trauma. The preoperative and operative management are discussed as well as the application of minimally invasive surgery for this rare process. RESULTS: Laparoscopic cholecystectomy was performed successfully. The patient did well postoperatively with no complications. No other injuries were identified at the time of laparoscopy. CONCLUSION: Minimally invasive techniques may be safely applied to blunt trauma of the gallbladder in certain circumstances.  (+info)

Hemobilia secondary to chronic cholecystitis. (7/57)

The term hemobilia is used to describe the presence of blood in the biliary tract. We report a case of symptomatic hemobilia associated with chronic cholecystitis in a 57-year-old man with jaundice, gastrointestinal hemorrhage, and epigastric pain. We review the etiology of this condition and highlight the role of abdominal ultrasonography in its diagnosis. In our case, abdominal ultrasonography revealed the presence of clots inside the gallbladder. The clinical condition was resolved by means of a cholecystectomy. The patient had an uneventful recovery.  (+info)

Gallbladder polyp as a manifestation of hemobilia caused by arterial-portal fistula after percutaneous liver biopsy: a case report. (8/57)

Outpatient percutaneous liver biopsy is a common practice in the differential diagnosis and treatment of chronic liver disease. The major complication and mortality rate were about 2-4% and 0.01-0.33% respectively. Arterio-portal fistula as a complication of percutaneous liver biopsy was infrequently seen and normally asymptomatic. Hemobilia, which accounted for about 3% of overall major percutaneous liver biopsy complications, resulted rarely from arterio-portal fistula We report a hemobilia case of 68 years old woman who was admitted for abdominal pain after liver biopsy. The initial ultrasonography revealed a gallbladder polypoid tumor and common bile duct (CBD) dilatation. Blood clot was extracted as endoscopic retrograde cholangiopancreatography (ERCP) showed hemobilia. The patient was shortly readmitted because of recurrence of symptoms. A celiac angiography showed an intrahepatic arterio-portal fistula. After superselective embolization of the feeding artery, the patient was discharged uneventfully. Most cases of hemobilia caused by percutaneous liver biopsy resolved spontaneously. Selective angiography embolization or surgical intervention is reserved for patients who failed to respond to conservative treatment.  (+info)

Hemobilia is a medical condition that refers to the presence of blood in the bile ducts, which can lead to the passage of blood in the stool or vomiting of blood (hematemesis). This condition usually results from a traumatic injury, rupture of a blood vessel, or a complication from a medical procedure involving the liver, gallbladder, or bile ducts. In some cases, hemobilia may also be caused by tumors or abnormal blood vessels in the liver. Symptoms of hemobilia can include abdominal pain, jaundice, and gastrointestinal bleeding. Diagnosis typically involves imaging tests such as CT scans or endoscopic retrograde cholangiopancreatography (ERCP) to visualize the bile ducts and identify the source of bleeding. Treatment may involve endovascular procedures, surgery, or other interventions to stop the bleeding and manage any underlying conditions.

The hepatic artery is a branch of the celiac trunk or abdominal aorta that supplies oxygenated blood to the liver. It typically divides into two main branches, the right and left hepatic arteries, which further divide into smaller vessels to supply different regions of the liver. The hepatic artery also gives off branches to supply other organs such as the gallbladder, pancreas, and duodenum.

It's worth noting that there is significant variability in the anatomy of the hepatic artery, with some individuals having additional branches or variations in the origin of the vessel. This variability can have implications for surgical procedures involving the liver and surrounding organs.

A false aneurysm, also known as a pseudoaneurysm, is a type of aneurysm that occurs when there is a leakage or rupture of blood from a blood vessel into the surrounding tissues, creating a pulsating hematoma or collection of blood. Unlike true aneurysms, which involve a localized dilation or bulging of the blood vessel wall, false aneurysms do not have a complete covering of all three layers of the arterial wall (intima, media, and adventitia). Instead, they are typically covered by only one or two layers, such as the intima and adventitia, or by surrounding tissues like connective tissue or fascia.

False aneurysms can result from various factors, including trauma, infection, iatrogenic causes (such as medical procedures), or degenerative changes in the blood vessel wall. They are more common in arteries than veins and can occur in any part of the body. If left untreated, false aneurysms can lead to serious complications such as rupture, thrombosis, distal embolization, or infection. Treatment options for false aneurysms include surgical repair, endovascular procedures, or observation with regular follow-up imaging.

Cholangitis is a medical condition characterized by inflammation of the bile ducts, which are the tubes that carry bile from the liver to the small intestine. Bile is a digestive juice produced by the liver that helps break down fats in food.

There are two types of cholangitis: acute and chronic. Acute cholangitis is a sudden and severe infection that can cause symptoms such as abdominal pain, fever, jaundice (yellowing of the skin and eyes), and dark urine. It is usually caused by a bacterial infection that enters the bile ducts through a blockage or obstruction.

Chronic cholangitis, on the other hand, is a long-term inflammation of the bile ducts that can lead to scarring and narrowing of the ducts. This can cause symptoms such as abdominal pain, itching, and jaundice. Chronic cholangitis can be caused by various factors, including primary sclerosing cholangitis (an autoimmune disease), bile duct stones, or tumors in the bile ducts.

Treatment for cholangitis depends on the underlying cause of the condition. Antibiotics may be used to treat bacterial infections, and surgery may be necessary to remove blockages or obstructions in the bile ducts. In some cases, medications may be prescribed to manage symptoms and prevent further complications.

A biliary fistula is an abnormal connection or passage between the biliary system (which includes the gallbladder, bile ducts, and liver) and another organ or structure, usually in the abdominal cavity. This connection allows bile, which is a digestive fluid produced by the liver, to leak out of its normal pathway and into other areas of the body.

Biliary fistulas can occur as a result of trauma, surgery, infection, or inflammation in the biliary system. Symptoms may include abdominal pain, fever, jaundice (yellowing of the skin and eyes), nausea, vomiting, and clay-colored stools. Treatment typically involves addressing the underlying cause of the fistula, such as draining an infection or repairing damaged tissue, and diverting bile flow away from the site of the leak. In some cases, surgery may be necessary to repair the fistula.

Cholecystectomy is a medical procedure to remove the gallbladder, a small pear-shaped organ located on the right side of the abdomen, just beneath the liver. The primary function of the gallbladder is to store and concentrate bile, a digestive fluid produced by the liver. During a cholecystectomy, the surgeon removes the gallbladder, usually due to the presence of gallstones or inflammation that can cause pain, infection, or other complications.

There are two primary methods for performing a cholecystectomy:

1. Open Cholecystectomy: In this traditional surgical approach, the surgeon makes an incision in the abdomen to access and remove the gallbladder. This method is typically used when there are complications or unique circumstances that make laparoscopic surgery difficult or risky.
2. Laparoscopic Cholecystectomy: This is a minimally invasive surgical procedure where the surgeon makes several small incisions in the abdomen, through which a thin tube with a camera (laparoscope) and specialized surgical instruments are inserted. The surgeon then guides these tools to remove the gallbladder while viewing the internal structures on a video monitor.

After the gallbladder is removed, bile flows directly from the liver into the small intestine through the common bile duct, and the body continues to function normally without any significant issues.

Cholecystitis is a medical condition characterized by inflammation of the gallbladder, a small pear-shaped organ located under the liver that stores and concentrates bile produced by the liver. Bile is a digestive fluid that helps break down fats in the small intestine during digestion.

Acute cholecystitis is a sudden inflammation of the gallbladder, often caused by the presence of gallstones that block the cystic duct, the tube that carries bile from the gallbladder to the common bile duct. This blockage can cause bile to build up in the gallbladder, leading to inflammation, swelling, and pain.

Chronic cholecystitis is a long-term inflammation of the gallbladder, often caused by repeated attacks of acute cholecystitis or the presence of gallstones that cause ongoing irritation and damage to the gallbladder wall. Over time, chronic cholecystitis can lead to thickening and scarring of the gallbladder wall, which can reduce its ability to function properly.

Symptoms of cholecystitis may include sudden and severe abdominal pain, often in the upper right or center of the abdomen, that may worsen after eating fatty foods; fever; nausea and vomiting; bloating and gas; and clay-colored stools. Treatment for cholecystitis typically involves antibiotics to treat any infection present, pain relief, and surgery to remove the gallbladder (cholecystectomy). In some cases, a nonsurgical procedure called endoscopic retrograde cholangiopancreatography (ERCP) may be used to remove gallstones from the bile duct.

Therapeutic embolization is a medical procedure that involves intentionally blocking or obstructing blood vessels to stop excessive bleeding or block the flow of blood to a tumor or abnormal tissue. This is typically accomplished by injecting small particles, such as microspheres or coils, into the targeted blood vessel through a catheter, which is inserted into a larger blood vessel and guided to the desired location using imaging techniques like X-ray or CT scanning. The goal of therapeutic embolization is to reduce the size of a tumor, control bleeding, or block off abnormal blood vessels that are causing problems.

Gallbladder diseases refer to a range of conditions that affect the function and structure of the gallbladder, a small pear-shaped organ located beneath the liver. The primary role of the gallbladder is to store, concentrate, and release bile into the small intestine to aid in digesting fats. Gallbladder diseases can be chronic or acute and may cause various symptoms, discomfort, or complications if left untreated. Here are some common gallbladder diseases with brief definitions:

1. Cholelithiasis: The presence of gallstones within the gallbladder. Gallstones are small, hard deposits made of cholesterol, bilirubin, or a combination of both, which can vary in size from tiny grains to several centimeters.
2. Cholecystitis: Inflammation of the gallbladder, often caused by obstruction of the cystic duct (the tube connecting the gallbladder and the common bile duct) due to a gallstone. This condition can be acute or chronic and may cause abdominal pain, fever, and tenderness in the right upper quadrant of the abdomen.
3. Choledocholithiasis: The presence of gallstones within the common bile duct, which can lead to obstruction, jaundice, and potential infection of the biliary system (cholangitis).
4. Acalculous gallbladder disease: Gallbladder dysfunction or inflammation without the presence of gallstones. This condition is often seen in critically ill patients and can lead to similar symptoms as cholecystitis.
5. Gallbladder polyps: Small growths attached to the inner wall of the gallbladder. While most polyps are benign, some may have malignant potential, especially if they are larger than 1 cm in size or associated with certain risk factors.
6. Gallbladder cancer: A rare form of cancer that originates in the gallbladder tissue. It is often asymptomatic in its early stages and can be challenging to diagnose. Symptoms may include abdominal pain, jaundice, or a palpable mass in the right upper quadrant of the abdomen.

It is essential to consult with a healthcare professional if experiencing symptoms related to gallbladder disease for proper diagnosis and treatment.

Biliary tract diseases refer to a group of medical conditions that affect the biliary system, which includes the gallbladder, bile ducts, and liver. Bile is a digestive juice produced by the liver, stored in the gallbladder, and released into the small intestine through the bile ducts to help digest fats.

Biliary tract diseases can cause various symptoms such as abdominal pain, jaundice, fever, nausea, vomiting, and changes in stool color. Some of the common biliary tract diseases include:

1. Gallstones: Small, hard deposits that form in the gallbladder or bile ducts made up of cholesterol or bilirubin.
2. Cholecystitis: Inflammation of the gallbladder, often caused by gallstones.
3. Cholangitis: Infection or inflammation of the bile ducts.
4. Biliary dyskinesia: A motility disorder that affects the contraction and relaxation of the muscles in the biliary system.
5. Primary sclerosing cholangitis: A chronic autoimmune disease that causes scarring and narrowing of the bile ducts.
6. Biliary tract cancer: Rare cancers that affect the gallbladder, bile ducts, or liver.

Treatment for biliary tract diseases varies depending on the specific condition and severity but may include medications, surgery, or a combination of both.

The common hepatic duct is a medical term that refers to the duct in the liver responsible for carrying bile from the liver. More specifically, it is the duct that results from the convergence of the right and left hepatic ducts, which themselves carry bile from the right and left lobes of the liver, respectively. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct, which ultimately drains into the duodenum, a part of the small intestine.

The primary function of the common hepatic duct is to transport bile, a digestive juice produced by the liver, to the small intestine. Bile helps break down fats during the digestion process, making it possible for the body to absorb them properly. Any issues or abnormalities in the common hepatic duct can lead to problems with bile flow and potentially cause health complications such as jaundice, gallstones, or liver damage.

Jaundice is a medical condition characterized by the yellowing of the skin, sclera (whites of the eyes), and mucous membranes due to an excess of bilirubin in the bloodstream. Bilirubin is a yellow-orange pigment produced when hemoglobin from red blood cells is broken down. Normally, bilirubin is processed by the liver and excreted through bile into the digestive system. However, if there's an issue with bilirubin metabolism or elimination, it can accumulate in the body, leading to jaundice.

Jaundice can be a symptom of various underlying conditions, such as liver diseases (hepatitis, cirrhosis), gallbladder issues (gallstones, tumors), or blood disorders (hemolysis). It is essential to consult a healthcare professional if jaundice is observed, as it may indicate a severe health problem requiring prompt medical attention.

Choledochostomy is a surgical procedure that involves creating an opening (stoma) into the common bile duct, which carries bile from the liver and gallbladder to the small intestine. This procedure is typically performed to relieve obstructions or blockages in the bile duct, such as those caused by gallstones, tumors, or scar tissue.

During the choledochostomy procedure, a surgeon makes an incision in the abdomen and exposes the common bile duct. The duct is then cut open, and a small tube (catheter) is inserted into the duct to allow bile to drain out of the body. The catheter may be left in place temporarily or permanently, depending on the underlying condition causing the obstruction.

Choledochostomy is typically performed as an open surgical procedure, but it can also be done using minimally invasive techniques such as laparoscopy or robotic-assisted surgery. As with any surgical procedure, choledochostomy carries risks such as bleeding, infection, and damage to surrounding tissues. However, these risks are generally low in the hands of an experienced surgeon.

Interventional radiology (IR) is a subspecialty of radiology that uses minimally invasive image-guided procedures to diagnose and treat various medical conditions. The main goal of interventional radiology is to offer patients less invasive options for treatment, which can result in smaller incisions, reduced recovery time, and fewer complications compared to traditional open surgeries.

Interventional radiologists use a variety of imaging techniques, such as X-rays, fluoroscopy, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound, to guide catheters, wires, needles, and other small instruments through the body to target specific areas. These targeted interventions can be used for both diagnostic and therapeutic purposes, including:

1. Biopsies: Obtaining tissue samples from organs or tumors to determine a diagnosis.
2. Drainage procedures: Removing fluid from abscesses, cysts, or blocked areas to alleviate symptoms and promote healing.
3. Stent placements: Opening narrowed or obstructed blood vessels, bile ducts, or airways using small mesh tubes called stents.
4. Embolization: Blocking abnormal blood vessels or reducing blood flow to tumors, aneurysms, or other problematic areas.
5. Tumor ablation: Destroying tumors using heat (radiofrequency ablation, microwave ablation), cold (cryoablation), or other energy sources.
6. Pain management: Treating chronic pain by targeting specific nerves and blocking their transmission of pain signals.
7. Vascular access: Creating secure pathways to blood vessels for dialysis, chemotherapy, or other long-term treatments.
8. Aneurysm repair: Reinforcing weakened or bulging blood vessel walls using coils, stents, or flow diverters.
9. Vertebroplasty and kyphoplasty: Stabilizing fractured vertebrae in the spine to alleviate pain and improve mobility.
10. Uterine fibroid embolization: Reducing the size and symptoms of uterine fibroids by blocking their blood supply.

These are just a few examples of interventional radiology procedures. The field is constantly evolving, with new techniques and technologies being developed to improve patient care and outcomes. Interventional radiologists work closely with other medical specialists to provide minimally invasive treatment options for a wide range of conditions.

Acute cholecystitis is a medical condition characterized by inflammation of the gallbladder (cholecystitis) that develops suddenly (acute). The gallbladder is a small pear-shaped organ located in the upper right part of the abdomen, beneath the liver. It stores bile, a digestive juice produced by the liver, which helps break down fats in the food we eat.

Acute cholecystitis occurs when the gallbladder becomes inflamed and irritated, often due to the presence of gallstones that block the cystic duct, the tube that carries bile from the gallbladder into the small intestine. When the cystic duct is obstructed, bile builds up in the gallbladder, causing it to become swollen, inflamed, and infected.

Symptoms of acute cholecystitis may include sudden and severe abdominal pain, often located in the upper right or middle part of the abdomen, that may radiate to the back or shoulder blade area. Other symptoms may include fever, nausea, vomiting, loss of appetite, and abdominal tenderness or swelling.

Acute cholecystitis is typically diagnosed through a combination of medical history, physical examination, laboratory tests, and imaging studies such as ultrasound or CT scan. Treatment may involve hospitalization, antibiotics to treat infection, pain relief medications, and surgery to remove the gallbladder (cholecystectomy). In some cases, nonsurgical treatments such as endoscopic sphincterotomy or percutaneous cholecystostomy may be used to relieve obstruction and inflammation.

Endoscopic retrograde cholangiopancreatography (ERCP) is a medical procedure that combines upper gastrointestinal (GI) endoscopy and fluoroscopy to diagnose and treat certain problems of the bile ducts and pancreas.

During ERCP, a flexible endoscope (a long, thin, lighted tube with a camera on the end) is passed through the patient's mouth and throat, then through the stomach and into the first part of the small intestine (duodenum). A narrow plastic tube (catheter) is then inserted through the endoscope and into the bile ducts and/or pancreatic duct. Contrast dye is injected through the catheter, and X-rays are taken to visualize the ducts.

ERCP can be used to diagnose a variety of conditions affecting the bile ducts and pancreas, including gallstones, tumors, strictures (narrowing of the ducts), and chronic pancreatitis. It can also be used to treat certain conditions, such as removing gallstones from the bile duct or placing stents to keep the ducts open in cases of stricture.

ERCP is an invasive procedure that carries a risk of complications, including pancreatitis, infection, bleeding, and perforation (a tear in the lining of the GI tract). It should only be performed by experienced medical professionals in a hospital setting.

Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive medical imaging technique that uses magnetic resonance imaging (MRI) to visualize the bile ducts and pancreatic duct. This diagnostic test does not use radiation like other imaging techniques such as computed tomography (CT) scans or endoscopic retrograde cholangiopancreatography (ERCP).

During an MRCP, the patient lies on a table that slides into the MRI machine. Contrast agents may be used to enhance the visibility of the ducts. The MRI machine uses a strong magnetic field and radio waves to produce detailed images of the internal structures, allowing radiologists to assess any abnormalities or blockages in the bile and pancreatic ducts.

MRCP is often used to diagnose conditions such as gallstones, tumors, inflammation, or strictures in the bile or pancreatic ducts. It can also be used to monitor the effectiveness of treatments for these conditions. However, it does not allow for therapeutic interventions like ERCP, which can remove stones or place stents.

An aneurysm is a localized, balloon-like bulge in the wall of a blood vessel. It occurs when the pressure inside the vessel causes a weakened area to swell and become enlarged. Aneurysms can develop in any blood vessel, but they are most common in arteries at the base of the brain (cerebral aneurysm) and the main artery carrying blood from the heart to the rest of the body (aortic aneurysm).

Aneurysms can be classified as saccular or fusiform, depending on their shape. A saccular aneurysm is a round or oval bulge that projects from the side of a blood vessel, while a fusiform aneurysm is a dilated segment of a blood vessel that is uniform in width and involves all three layers of the arterial wall.

The size and location of an aneurysm can affect its risk of rupture. Generally, larger aneurysms are more likely to rupture than smaller ones. Aneurysms located in areas with high blood pressure or where the vessel branches are also at higher risk of rupture.

Ruptured aneurysms can cause life-threatening bleeding and require immediate medical attention. Symptoms of a ruptured aneurysm may include sudden severe headache, neck stiffness, nausea, vomiting, blurred vision, or loss of consciousness. Unruptured aneurysms may not cause any symptoms and are often discovered during routine imaging tests for other conditions.

Treatment options for aneurysms depend on their size, location, and risk of rupture. Small, unruptured aneurysms may be monitored with regular imaging tests to check for growth or changes. Larger or symptomatic aneurysms may require surgical intervention, such as clipping or coiling, to prevent rupture and reduce the risk of complications.

Bile duct neoplasms, also known as cholangiocarcinomas, refer to a group of malignancies that arise from the bile ducts. These are the tubes that carry bile from the liver to the gallbladder and small intestine. Bile duct neoplasms can be further classified based on their location as intrahepatic (within the liver), perihilar (at the junction of the left and right hepatic ducts), or distal (in the common bile duct).

These tumors are relatively rare, but their incidence has been increasing in recent years. They can cause a variety of symptoms, including jaundice, abdominal pain, weight loss, and fever. The diagnosis of bile duct neoplasms typically involves imaging studies such as CT or MRI scans, as well as blood tests to assess liver function. In some cases, a biopsy may be necessary to confirm the diagnosis.

Treatment options for bile duct neoplasms depend on several factors, including the location and stage of the tumor, as well as the patient's overall health. Surgical resection is the preferred treatment for early-stage tumors, while chemotherapy and radiation therapy may be used in more advanced cases. For patients who are not candidates for surgery, palliative treatments such as stenting or bypass procedures may be recommended to relieve symptoms and improve quality of life.

Gallstones are small, hard deposits that form in the gallbladder, a small organ located under the liver. They can range in size from as small as a grain of sand to as large as a golf ball. Gallstones can be made of cholesterol, bile pigments, or calcium salts, or a combination of these substances.

There are two main types of gallstones: cholesterol stones and pigment stones. Cholesterol stones are the most common type and are usually yellow-green in color. They form when there is too much cholesterol in the bile, which causes it to become saturated and form crystals that eventually grow into stones. Pigment stones are smaller and darker in color, ranging from brown to black. They form when there is an excess of bilirubin, a waste product produced by the breakdown of red blood cells, in the bile.

Gallstones can cause symptoms such as abdominal pain, nausea, vomiting, and bloating, especially after eating fatty foods. In some cases, gallstones can lead to serious complications, such as inflammation of the gallbladder (cholecystitis), infection, or blockage of the bile ducts, which can cause jaundice, a yellowing of the skin and eyes.

The exact cause of gallstones is not fully understood, but risk factors include being female, older age, obesity, a family history of gallstones, rapid weight loss, diabetes, and certain medical conditions such as cirrhosis or sickle cell anemia. Treatment for gallstones may involve medication to dissolve the stones, shock wave therapy to break them up, or surgery to remove the gallbladder.

Laparoscopic cholecystectomy is a surgical procedure to remove the gallbladder using a laparoscope, a thin tube with a camera, which allows the surgeon to view the internal structures on a video monitor. The surgery is performed through several small incisions in the abdomen, rather than a single large incision used in open cholecystectomy. This approach results in less postoperative pain, fewer complications, and shorter recovery time compared to open cholecystectomy.

The procedure is typically indicated for symptomatic gallstones or chronic inflammation of the gallbladder (cholecystitis), which can cause severe abdominal pain, nausea, vomiting, and fever. Laparoscopic cholecystectomy has become the standard of care for gallbladder removal due to its minimally invasive nature and excellent outcomes.

The pancreatic ducts are a set of tubular structures within the pancreas that play a crucial role in the digestive system. The main pancreatic duct, also known as the duct of Wirsung, is responsible for transporting pancreatic enzymes and bicarbonate-rich fluid from the pancreas to the duodenum, which is the first part of the small intestine.

The exocrine portion of the pancreas contains numerous smaller ducts called interlobular ducts and intralobular ducts that merge and ultimately join the main pancreatic duct. This system ensures that the digestive enzymes and fluids produced by the pancreas are effectively delivered to the small intestine, where they aid in the breakdown and absorption of nutrients from food.

In addition to the main pancreatic duct, there is an accessory pancreatic duct, also known as Santorini's duct, which can sometimes join the common bile duct before emptying into the duodenum through a shared opening called the ampulla of Vater. However, in most individuals, the accessory pancreatic duct usually drains into the main pancreatic duct before entering the duodenum.

Choledocholithiasis is a medical condition characterized by the presence of one or more gallstones in the common bile duct, which is the tube that carries bile from the liver and gallbladder to the small intestine. Bile is a digestive fluid produced by the liver that helps break down fats in the small intestine. Gallstones are hardened deposits of digestive fluids that can form in the gallbladder or, less commonly, in the bile ducts.

Choledocholithiasis can cause a variety of symptoms, including abdominal pain, jaundice (yellowing of the skin and eyes), nausea, vomiting, and fever. If left untreated, it can lead to serious complications such as infection or inflammation of the bile ducts or pancreas, which can be life-threatening.

The condition is typically diagnosed through imaging tests such as ultrasound, CT scan, or MRI, and may require endoscopic or surgical intervention to remove the gallstones from the common bile duct.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Pancreatitis is a medical condition characterized by inflammation of the pancreas, a gland located in the abdomen that plays a crucial role in digestion and regulating blood sugar levels. The inflammation can be acute (sudden and severe) or chronic (persistent and recurring), and it can lead to various complications if left untreated.

Acute pancreatitis often results from gallstones or excessive alcohol consumption, while chronic pancreatitis may be caused by long-term alcohol abuse, genetic factors, autoimmune conditions, or metabolic disorders like high triglyceride levels. Symptoms of acute pancreatitis include severe abdominal pain, nausea, vomiting, fever, and increased heart rate, while chronic pancreatitis may present with ongoing abdominal pain, weight loss, diarrhea, and malabsorption issues due to impaired digestive enzyme production. Treatment typically involves supportive care, such as intravenous fluids, pain management, and addressing the underlying cause. In severe cases, hospitalization and surgery may be necessary.

The common bile duct is a duct that results from the union of the cystic duct (which drains bile from the gallbladder) and the common hepatic duct (which drains bile from the liver). The common bile duct transports bile, a digestive enzyme, from the liver and gallbladder to the duodenum, which is the first part of the small intestine.

The common bile duct runs through the head of the pancreas before emptying into the second part of the duodenum, either alone or in conjunction with the pancreatic duct, via a small opening called the ampulla of Vater. The common bile duct plays a crucial role in the digestion of fats by helping to break them down into smaller molecules that can be absorbed by the body.
