Leiomyosarcoma of the esophagus in a patient with chagasic megaesophagus: case report and literature review. (1/309)

Leiomyosarcoma constitutes approximately 0.5% of the malignant neoplasias of the esophagus and its association with megaesophagus has not been described. We report on a case of a woman with dysphagia that was slowly progressive from the age of 19 due to chagasic megaesophagus. The woman was subjected to cardiomyotomy at the age of 49. She presented a rapid worsening of the dysphagia due to leiomyosarcoma at the age of 61, and was subjected to subtotal esophagectomy with cervical esophagogastroplasty. She developed pulmonary and hepatic metastases 14 months after surgery and died six months later.  (+info)

Early experience with intrasphincteric botulinum toxin in the treatment of achalasia. (2/309)

BACKGROUND: Recent reports have suggested that intrasphincteric injection of botulinum toxin is effective and long-lasting in the treatment of achalasia. AIM: To report our experience of botulinum toxin injection in a prospective series of consecutive patients with achalasia. METHODS: Eleven consecutive patients with achalasia (eight male, mean age 55 years, range 20-87) were treated with 60 units of botulinum toxin (Dysport; Speywood Pharmaceuticals Ltd, UK) into each of four quadrants at the lower oesophageal sphincter. Patients were assessed pre-treatment and 1 month after treatment using a symptom score and oesophageal manometry. Median follow-up was 12 months (range 6-28). RESULTS: The injection procedure was simple to perform and free of adverse effects. Although treatment had a beneficial effect on dysphagia (median pre-treatment score 3 [interquartile range 3-3]; post-treatment score 2 [0-3]: P=0.03) 1 month following therapy, there was no significant improvement in chest pain or regurgitation scores. Similarly, no significant reduction in median lower oesophageal sphincter pressure was observed (29.5 mmHg [21-42] pre-treatment, 28.5 [17.5-55.5] post-treatment P=0.67). Four patients (36%) required further therapy within 3 months and the overall relapse rate was 73% (eight of 11) within 2 years. CONCLUSION: Although botulinum toxin injection was well tolerated, these results using Dysport at a dose of 240 mouse units question its efficacy as a treatment for achalasia.  (+info)

Minimally invasive surgery for achalasia: an 8-year experience with 168 patients. (3/309)

BACKGROUND: Seven years ago, the authors reported on the feasibility and short-term results of minimally invasive surgical methods to treat esophageal achalasia. In this report, they describe the evolution of the surgical technique and the clinical results in a large group of patients with long follow-up. PATIENTS AND METHODS: Between January 1991 and October 1998, 168 patients (96 men, 72 women; mean age 45 years, median duration of symptoms 48 months), who fulfilled the clinical, radiographic, endoscopic, and manometric criteria for a diagnosis of achalasia, underwent esophagomyotomy by minimally invasive techniques. Forty-eight patients had marked esophageal dilatation (diameter >6.0 cm). Thirty-five patients had a left thoracoscopic myotomy, and 133 patients had a laparoscopic myotomy plus a partial fundoplication. Follow-up to October 1998 was complete in 145 patients (86%). RESULTS: Median hospital stay was 72 hours for the thoracoscopic group and 48 hours for the laparoscopic group. Eight patients required a second operation for recurrent or persistent dysphagia, and two patients required an esophagectomy. There were no deaths. Good or excellent relief of dysphagia was obtained in 90% of patients (85% after thoracoscopic and 93% after laparoscopic myotomy). Gastroesophageal reflux developed in 60% of tested patients after thoracoscopic myotomy and in 17% after laparoscopic myotomy plus fundoplication. Laparoscopic myotomy plus fundoplication corrected reflux present before surgery in five of seven patients. Patients with a dilated esophagus had excellent relief of dysphagia after laparoscopic myotomy; none required an esophagectomy. CONCLUSIONS: Minimally invasive techniques provided effective and long-lasting relief of dysphagia in patients with achalasia. The authors prefer the laparoscopic approach for three reasons: it more effectively relieved dysphagia, it was associated with a shorter hospital stay, and it was associated with less postoperative reflux. Laparoscopic Heller myotomy and partial fundoplication should be considered the primary treatment for esophageal achalasia.  (+info)

Comparison of two different formulations of botulinum toxin A for the treatment of oesophageal achalasia. The Gismad Achalasia Study Group. (4/309)

BACKGROUND: Intrasphincteric injection of botulinum toxin has been reported as a safe and effective alternative treatment in oesophageal achalasia, especially in high-risk and elderly patients. AIM: : To compare two formulations of botulinum toxin in the management of achalasia. PATIENTS AND METHODS: We randomly compared the efficacy and safety of 100 U of Botox (Allergan, Irvine, USA) and 250 U of Dysport (Ipsen, Milan, Italy), injected through a sclerotherapy needle at the level of the lower oesophageal sphincter, in 78 consecutive patients with achalasia. Symptom score, oesophageal manometry and 24 h pH-metry were recorded (before and 1 month after therapy). Symptom score was also obtained 6 months after treatment. RESULTS: One month after treatment, the effects of the toxin on symptoms and oesophageal tests were similar for both formulations. Lower oesophageal sphincter pressure decreased from 31 +/- 12 to 18 +/- 5 mmHg after Botox, and from 35 +/- 9 to 18 +/- 10 after Dysport. At the end of the follow-up period (6 months), symptom score decreased from 5 +/- 1.2 to 1.2 +/- 0.8 after Botox and from 5.2 +/- 1.5 to 1.5 +/- 1 after Dysport. Moreover, the percentages of patients who failed to respond to treatment (10% and 17.5%) and who relapsed during follow-up (12% and 24%) did not differ significantly. No patient complained of reflux symptoms after treatment, although abnormal acid exposure was documented in two subjects. CONCLUSIONS: Both formulations of botulinum toxin have comparable efficacy in the treatment of oesophageal achalasia, for up to 6 months of follow-up.  (+info)

Review article: pharmacological options in achalasia. (5/309)

Achalasia is a common primary oesophageal motor disorder. Treatment has been based traditionally on a surgical approach; however, there is new evidence that some medical strategies may be of benefit. The purpose of the present article was to review the current medical management of achalasia. A Medline search identified original articles and reviews published in the English-language literature between 1966 and 1998. This search has revealed that the pharmacological treatment of achalasia is limited to some subgroups of patients (for example, early stages of the disease and elderly patients), and that nitrates, nifedipine, and botulinum toxin are the best studied and most effective compounds.  (+info)

Complete lower esophageal sphincter relaxation observed in some achalasia patients is functionally inadequate. (6/309)

Generally accepted manometric criteria for the diagnosis of achalasia are absent peristalsis and incomplete lower esophageal sphincter (LES) relaxation. However, in some patients with otherwise typical features of achalasia, esophageal manometry shows complete LES relaxation during swallowing. To establish whether such apparently complete LES relaxations are functionally adequate, we quantified changes in resistance to flow at the esophagogastric junction (EGJ) during wet swallowing. We studied seven achalasia patients with manometrically complete (>80%) LES relaxation, eight achalasia patients with incomplete (<40%) LES relaxation, and eight healthy volunteers. Complete LES relaxation on standard manometry (open-tip catheters) was confirmed in five of the seven achalasia patients by a Dentsleeve. Changes in EGJ resistance to flow were quantified using a pneumatic resistometer. Manometrically, the relaxation time span was significantly longer in patients with complete LES relaxation than in those with incomplete relaxation (7. 3 +/- 0.5 vs. 4.4 +/- 0.7 s; P < 0.05). The fall in EGJ resistance from basal values during swallowing was markedly reduced in both achalasia groups (21 +/- 8% in those with manometrically complete relaxation and 4 +/- 2% in those with incomplete relaxation) by comparison with healthy individuals, in whom resistance fell by 90 +/- 3% (P < 0.05 vs. both achalasia groups). The duration of EGJ resistance drop was also much shorter in achalasia with (0.7 +/- 0.2 s) and without (0.2 +/- 0.1 s) complete LES relaxation compared with healthy control values (6.6 +/- 1.2 s). Our results reveal that the apparently complete LES relaxation observed manometrically in some patients with achalasia is functionally inadequate since it is not associated with the normal profound fall in EGJ resistance to flow.  (+info)

A multicentre randomised study of intrasphincteric botulinum toxin in patients with oesophageal achalasia. GISMAD Achalasia Study Group. (7/309)

BACKGROUND: Intrasphincteric injection of botulinum toxin (Botx) has been proposed as treatment for oesophageal achalasia. However, the predictors of response and optimal dose remain unclear. AIMS: To compare the effect of different doses of Botx and to identify predictors of response. PATIENTS/METHODS: A total of 118 achalasic patients were randomised to receive one of three doses of Botx in a single injection: 50 U (n=40), 100 U (n=38), and 200 U (n=40). Of those who received 100 U, responsive patients were reinjected with an identical dose after 30 days. Clinical and manometric assessments were performed at baseline, 30 days after the initial injection of botulinum toxin, and at the end of follow up (mean 12 months; range 7-24 months). RESULTS: Thirty days after the initial injection, 82% of patients were considered responders without a clear dose related effect. At the end of follow up however, relapse of symptoms was evident in 19% of patients who received two injections of 100 U compared with 47% and 43% in the 50 U and 200 U groups, respectively. Using Kaplan-Meier analysis, patients in the 100x2 U group were more likely to remain in remission at any time (p<0.04), with 68% (95% CI 59-83) still in remission at 24 months. In a multiple adjusted model, response to Botx was independently predicted by the occurrence of vigorous achalasia (odds ratio 3.3) and the 100x2 U regimen (odds ratio 3.2). CONCLUSIONS: Two injections of 100 U of Botx 30 days apart appeared to be the most effective therapeutic schedule. The presence of vigorous achalasia was the principal determinant of the response to Botx.  (+info)

Upper esophageal sphincter pressure in patients with Chagas' disease and primary achalasia. (8/309)

The most important component of the upper esophageal sphincter (UES) is the cricopharyngeal muscle. During the measurement of sphincter pressure the catheter passed through the sphincter affects the pressure value. In Chagas' disease and primary achalasia there is an esophageal myenteric plexus denervation which may affect UES pressure. We measured the UES pressure of 115 patients with Chagas' disease, 28 patients with primary achalasia and 40 healthy volunteers. We used a round manometric catheter with continuous perfusion and the rapid pull-through method, performed in triplicate during apnea. Pressures were measured in four directions, and the direction with the highest pressure (anterior/posterior) and the average of the four directions were measured. The highest UES pressure in Chagas' disease patients without abnormalities upon radiologic esophageal examination (N = 63) was higher than in normal volunteers (142.8 +/- 47.4 mmHg vs 113.0 +/- 46.0 mmHg, mean +/- SD, P<0.05). There was no difference in UES pressure between patients with primary achalasia and patients with Chagas' disease and similar esophageal involvement and normal volunteers (P>0.05). There was no difference between patients with or without esophageal dilation. In the group of subjects less than 50 years of age the UES pressure of primary achalasia (N = 21) was lower than that of Chagas' disease patients with normal radiologic esophageal examination (N = 41), measured at the site with the highest pressure (109.3 +/- 31.5 mmHg vs 149.6 +/- 45.3 mmHg, P<0.01) and as the average of the four directions (64.2 +/- 17.1 mmHg vs 83.5 +/- 28.6 mmHg, P<0.05). We conclude that there is no difference in UES pressure between patients with Chagas' disease, primary achalasia and normal volunteers, except for patients with minor involvement by Chagas' disease, for whom the UES pressure at the site with the highest pressure was higher than the pressure of normal volunteers and patients with primary achalasia.  (+info)

Esophageal achalasia is a rare disorder of the esophagus, the tube that carries food from the mouth to the stomach. In this condition, the muscles at the lower end of the esophagus fail to relax properly during swallowing, making it difficult for food and liquids to pass into the stomach. This results in symptoms such as difficulty swallowing (dysphagia), regurgitation of food, chest pain, and weight loss. The cause of esophageal achalasia is not fully understood, but it is believed to be related to damage to the nerves that control the muscles of the esophagus. Treatment options include medications to relax the lower esophageal sphincter, botulinum toxin injections, and surgical procedures such as laparoscopic Heller myotomy or peroral endoscopic myotomy (POEM).

Dilation, also known as dilatation, refers to the process of expanding or enlarging a body passage or cavity. In medical terms, it typically refers to the widening of a bodily opening or hollow organ, allowing for increased flow or access. This can occur naturally, such as during childbirth when the cervix dilates to allow for the passage of a baby, or it can be induced through medical procedures or interventions.

For example, dilation of the pupils is a natural response to darkness or certain medications, while dilation of blood vessels is a common side effect of some drugs and can also occur in response to changes in temperature or emotional state. Dilation of the stomach or intestines may be necessary for medical procedures such as endoscopies or surgeries.

It's important to note that dilation can also refer to the abnormal enlargement of a body part, such as dilated cardiomyopathy, which refers to an enlarged and weakened heart muscle.

Manometry is a medical test that measures pressure inside various parts of the gastrointestinal tract. It is often used to help diagnose digestive disorders such as achalasia, gastroparesis, and irritable bowel syndrome. During the test, a thin, flexible tube called a manometer is inserted through the mouth or rectum and into the area being tested. The tube is connected to a machine that measures and records pressure readings. These readings can help doctors identify any abnormalities in muscle function or nerve reflexes within the digestive tract.

Esophagoscopy is a medical procedure that involves the visual examination of the esophagus, which is the tube that connects the throat to the stomach. This procedure is typically carried out using an esophagogastroduodenoscope (EGD), a flexible tube with a camera and light on the end.

During the procedure, the EGD is inserted through the mouth and down the throat into the esophagus, allowing the medical professional to examine its lining for any abnormalities such as inflammation, ulcers, or tumors. The procedure may also involve taking tissue samples (biopsies) for further examination and testing.

Esophagoscopy is commonly used to diagnose and monitor conditions such as gastroesophageal reflux disease (GERD), Barrett's esophagus, esophageal cancer, and other disorders affecting the esophagus. It may also be used to treat certain conditions, such as removing polyps or foreign objects from the esophagus.

Fundoplication is a surgical procedure in which the upper part of the stomach (the fundus) is wrapped around the lower esophagus and then stitched into place. This procedure strengthens the lower esophageal sphincter, which helps prevent acid reflux from the stomach into the esophagus. It is commonly used to treat gastroesophageal reflux disease (GERD) and paraesophageal hernias.

The esophagus is the muscular tube that connects the throat (pharynx) to the stomach. It is located in the midline of the neck and chest, passing through the diaphragm to enter the abdomen and join the stomach. The main function of the esophagus is to transport food and liquids from the mouth to the stomach for digestion.

The esophagus has a few distinct parts: the upper esophageal sphincter (a ring of muscle that separates the esophagus from the throat), the middle esophagus, and the lower esophageal sphincter (another ring of muscle that separates the esophagus from the stomach). The lower esophageal sphincter relaxes to allow food and liquids to enter the stomach and then contracts to prevent stomach contents from flowing back into the esophagus.

The walls of the esophagus are made up of several layers, including mucosa (a moist tissue that lines the inside of the tube), submucosa (a layer of connective tissue), muscle (both voluntary and involuntary types), and adventitia (an outer layer of connective tissue).

Common conditions affecting the esophagus include gastroesophageal reflux disease (GERD), Barrett's esophagus, esophageal cancer, esophageal strictures, and eosinophilic esophagitis.

Laparoscopy is a surgical procedure that involves the insertion of a laparoscope, which is a thin tube with a light and camera attached to it, through small incisions in the abdomen. This allows the surgeon to view the internal organs without making large incisions. It's commonly used to diagnose and treat various conditions such as endometriosis, ovarian cysts, infertility, and appendicitis. The advantages of laparoscopy over traditional open surgery include smaller incisions, less pain, shorter hospital stays, and quicker recovery times.

Anti-dyskinetic agents are a class of medications that are used to treat or manage dyskinesias, which are involuntary movements or abnormal muscle contractions. These medications work by blocking or reducing the activity of dopamine, a neurotransmitter in the brain that is involved in movement control.

Dyskinetic symptoms can occur as a side effect of long-term use of levodopa therapy in patients with Parkinson's disease. Anti-dyskinetic agents such as amantadine, anticholinergics, and dopamine agonists may be used to manage these symptoms.

Amantadine works by increasing the release of dopamine and blocking its reuptake, which can help reduce dyskinesias. Anticholinergic medications such as trihexyphenidyl and benztropine work by blocking the action of acetylcholine, another neurotransmitter that can contribute to dyskinesias. Dopamine agonists such as pramipexole and ropinirole mimic the effects of dopamine in the brain and can help reduce dyskinesias by reducing the dose of levodopa required for symptom control.

It is important to note that anti-dyskinetic agents may have side effects, and their use should be carefully monitored by a healthcare provider.

The lower esophageal sphincter (LES) is a specialized ring of muscle located at the junction of the esophagus and stomach. It functions as a physiological valve that regulates the direction of content flow between the esophagus and the stomach. Normally, the LES remains contracted to prevent the reflux of gastric contents into the esophagus, and it relaxes during swallowing to allow food to enter the stomach.

A dysfunctional lower esophageal sphincter may lead to gastroesophageal reflux disease (GERD), where stomach acid frequently backs up into the esophagus, causing symptoms such as heartburn, chest pain, and difficulty swallowing.

The esophagogastric junction (EGJ) is the region of the gastrointestinal tract where the esophagus (the tube that carries food from the mouth to the stomach) meets the stomach. It serves as a physiological sphincter, which helps control the direction of flow and prevent reflux of gastric contents back into the esophagus. The EGJ is also known as the gastroesophageal junction or cardia.

Deglutition disorders, also known as swallowing disorders, are conditions that affect the ability to move food or liquids from the mouth to the stomach safely and efficiently. These disorders can occur at any stage of the swallowing process, which includes oral preparation (chewing and manipulating food in the mouth), pharyngeal phase (activating muscles and structures in the throat to move food toward the esophagus), and esophageal phase (relaxing and contracting the esophagus to propel food into the stomach).

Symptoms of deglutition disorders may include coughing or choking during or after eating, difficulty initiating a swallow, food sticking in the throat or chest, regurgitation, unexplained weight loss, and aspiration (inhaling food or liquids into the lungs), which can lead to pneumonia.

Deglutition disorders can be caused by various factors, such as neurological conditions (e.g., stroke, Parkinson's disease, multiple sclerosis), structural abnormalities (e.g., narrowing or blockage of the esophagus), muscle weakness or dysfunction, and cognitive or behavioral issues. Treatment for deglutition disorders may involve dietary modifications, swallowing exercises, medications, or surgical interventions, depending on the underlying cause and severity of the condition.

Esophagoplasty is a surgical procedure that involves reconstructing or reshaping the esophagus, which is the muscular tube that connects the throat to the stomach. This procedure may be performed to treat various conditions such as esophageal atresia (a birth defect in which the esophagus does not develop properly), esophageal stricture (narrowing of the esophagus), or esophageal cancer.

During an esophagoplasty, a surgeon may use tissue from another part of the body, such as the stomach or colon, to reconstruct the esophagus. The specific technique used will depend on the individual patient's needs and the nature of their condition.

It is important to note that esophagoplasty is a complex surgical procedure that carries risks such as bleeding, infection, and complications related to anesthesia. Patients who undergo this procedure may require extensive postoperative care and rehabilitation to recover fully.

Peristalsis is an involuntary muscular movement that occurs in the digestive tract, including the esophagus, stomach, and intestines. It is characterized by alternate contraction and relaxation of the smooth muscles in the walls of these organs, which creates a wave-like motion that helps propel food, fluids, and waste through the digestive system.

The process of peristalsis begins with a narrowing or constriction of the muscle in one area of the digestive tract, followed by a relaxation of the muscle in the adjacent area. This creates a localized contraction that moves along the length of the organ, pushing its contents forward. The wave of contractions continues to move along the digestive tract until it reaches the anus, where waste is eliminated from the body.

Peristalsis plays a crucial role in maintaining proper digestion and absorption of nutrients, as well as in the elimination of waste products from the body. Disorders that affect peristalsis, such as gastrointestinal motility disorders, can lead to symptoms such as abdominal pain, bloating, constipation, or diarrhea.

Barium sulfate is a medication that is commonly used as a contrast material in medical imaging procedures, such as X-rays and CT scans. It works by coating the inside of the digestive tract, making it visible on an X-ray or CT scan and allowing doctors to see detailed images of the stomach, intestines, and other parts of the digestive system.

Barium sulfate is a white, chalky powder that is mixed with water to create a thick, milky liquid. It is generally safe and does not cause significant side effects when used in medical imaging procedures. However, it should not be taken by individuals who have a known allergy to barium or who have certain digestive conditions, such as obstructions or perforations of the bowel.

It's important to note that while barium sulfate is an important tool for medical diagnosis, it is not a treatment for any medical condition and should only be used under the direction of a healthcare professional.

Esophageal motility disorders are a group of conditions that affect the normal movement (motility) of the muscles in the esophagus, which is the tube that connects the throat to the stomach. The esophageal muscles normally contract and relax in a coordinated manner to help move food from the mouth to the stomach.

In esophageal motility disorders, this muscle movement is impaired, leading to difficulty swallowing (dysphagia), chest pain, heartburn, or regurgitation of food. Some common examples of esophageal motility disorders include:

1. Achalasia: a condition in which the lower esophageal sphincter muscle fails to relax properly, preventing food from passing into the stomach.
2. Diffuse esophageal spasm: a disorder characterized by uncoordinated contractions of the esophageal muscles, leading to difficulty swallowing and chest pain.
3. Nutcracker esophagus: a condition in which the esophageal muscles contract too forcefully, causing pain and difficulty swallowing.
4. Hypertensive lower esophageal sphincter: a disorder in which the lower esophageal sphincter muscle is too tight, making it difficult to swallow and leading to symptoms such as heartburn and regurgitation.
5. Ineffective esophageal motility: a condition in which the esophageal muscles have weak or disorganized contractions, leading to difficulty swallowing and other symptoms.

Esophageal motility disorders can be diagnosed through tests such as manometry, which measures the pressure and coordination of esophageal muscle contractions, or barium swallow studies, which use X-rays to visualize the movement of food through the esophagus. Treatment may include medications, lifestyle changes, or surgery, depending on the specific disorder and its severity.

Catheterization is a medical procedure in which a catheter (a flexible tube) is inserted into the body to treat various medical conditions or for diagnostic purposes. The specific definition can vary depending on the area of medicine and the particular procedure being discussed. Here are some common types of catheterization:

1. Urinary catheterization: This involves inserting a catheter through the urethra into the bladder to drain urine. It is often performed to manage urinary retention, monitor urine output in critically ill patients, or assist with surgical procedures.
2. Cardiac catheterization: A procedure where a catheter is inserted into a blood vessel, usually in the groin or arm, and guided to the heart. This allows for various diagnostic tests and treatments, such as measuring pressures within the heart chambers, assessing blood flow, or performing angioplasty and stenting of narrowed coronary arteries.
3. Central venous catheterization: A catheter is inserted into a large vein, typically in the neck, chest, or groin, to administer medications, fluids, or nutrition, or to monitor central venous pressure.
4. Peritoneal dialysis catheterization: A catheter is placed into the abdominal cavity for individuals undergoing peritoneal dialysis, a type of kidney replacement therapy.
5. Neurological catheterization: In some cases, a catheter may be inserted into the cerebrospinal fluid space (lumbar puncture) or the brain's ventricular system (ventriculostomy) to diagnose or treat various neurological conditions.

These are just a few examples of catheterization procedures in medicine. The specific definition and purpose will depend on the medical context and the particular organ or body system involved.

Esophageal diseases refer to a range of medical conditions that affect the esophagus, which is the muscular tube that connects the throat to the stomach. Here are some common esophageal diseases with their brief definitions:

1. Gastroesophageal reflux disease (GERD): A chronic condition in which stomach acid or bile flows back into the esophagus, causing symptoms such as heartburn, chest pain, and difficulty swallowing.
2. Esophagitis: Inflammation of the esophageal lining, often caused by GERD, infection, or medication.
3. Esophageal stricture: Narrowing of the esophagus due to scarring or inflammation, which can make swallowing difficult.
4. Esophageal cancer: Cancer that forms in the tissues of the esophagus, often as a result of long-term GERD or smoking.
5. Esophageal motility disorders: Disorders that affect the normal movement and function of the esophagus, such as achalasia, diffuse spasm, and nutcracker esophagus.
6. Barrett's esophagus: A condition in which the lining of the lower esophagus changes, increasing the risk of esophageal cancer.
7. Esophageal diverticula: Small pouches that form in the esophageal wall, often causing difficulty swallowing or regurgitation.
8. Eosinophilic esophagitis (EoE): A chronic immune-mediated disorder characterized by inflammation of the esophagus due to an allergic reaction.

These are some of the common esophageal diseases, and their diagnosis and treatment may vary depending on the severity and underlying cause of the condition.
