Myotomy
Myotomy is a surgical procedure that involves cutting a muscle to relieve constriction, often performed in the gastrointestinal or urological systems. The procedure can alleviate symptoms caused by muscle-related functional obstructions, particularly in cases of achalasia, a disorder that affects the esophagus. Myotomies may be performed using open, laparoscopic, or endoscopic techniques, depending on the location and condition being treated. Common types include the Heller myotomy, used to treat esophageal achalasia, and pyloromyotomy, commonly performed in infants with pyloric stenosis. Indications Myotomy is indicated in various conditions characterized by muscular constriction that interferes with normal physiological functions. The most common indications include: * Achalasia – A motility disorder where the lower esophageal sphincter (LES) fails to relax, obstructing food passage. * Pyloric stenosis – Hypertrophy of the pyloric sphincter in infants, preventing food f ...

Achalasia
Esophageal achalasia, often referred to simply as achalasia, is a failure of smooth muscle fibers to relax, which can cause the lower esophageal sphincter to remain closed. Without a modifier, "achalasia" usually refers to achalasia of the esophagus. Achalasia can happen at various points along the human gastrointestinal tract, gastrointestinal tract; achalasia of the rectum, for instance, may occur in Hirschsprung's disease. The lower esophageal sphincter is a muscle between the esophagus and stomach that opens when food comes in. It closes to avoid Gastric acid, stomach acids from coming back up. A fully understood cause to the disease is unknown, as are factors that increase the risk of its appearance. Suggestions of a Genetic disorder, genetically transmittable form of achalasia exist, but this is neither fully understood, nor agreed upon. Esophageal achalasia is an esophageal motility disorder involving the smooth muscle cell, smooth muscle layer of the esophagus and the lowe ...

Pyloromyotomy
Pyloromyotomy is a surgical procedure in which a portion of the muscle fibers of the pyloric muscle are cut. This is typically done in cases where the contents from the stomach are inappropriately stopped by the pyloric muscle, causing the stomach contents to build up in the stomach and unable to be appropriately digested. The procedure is typically performed in cases of " hypertrophic pyloric stenosis" in young children. In most cases, the procedure can be performed with either an open approach or a laparoscopic approach and the patients typically have good outcomes with minimal complications. History and development The development of the procedure has attributed to Dr. Conrad Ramstedt in 1911, who originally named the procedure Ramstedt's Operation. However, the procedure was truly performed about 17 months earlier by Sir Harold Stiles in 1910 at the Royal Hospital for sick children. In 1991, the first laparoscopic pyloromyotomy was performed by Dr. Alain and Dr. Grousse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heller Myotomy
Heller myotomy is a surgical procedure in which the muscles of the cardia ( lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach. It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach. History and development It was first performed by Ernst Heller (1877–1964) in 1913. Then and until recently, this surgery was performed using an open procedure, either through the chest ( thoracotomy) or through the abdomen (laparotomy). However, open procedures involve greater recovery times. Modern Heller myotomy is normally performed using minimally invasive laparoscopic techniques, which minimize risks and speeds recovery significantly. The 100th anniversary of Heller's description of the surgical treatment of patients with achalasia was celebrated in 2014. Procedure During the procedure, the patient is put under general anaesthesia. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Surgeries By Type
Many Surgery, surgical procedure names can be broken into parts to indicate the meaning. For example, in gastrectomy, "ectomy" is a suffix (linguistics), suffix meaning the removal of a part of the body. "Gastro-" means stomach. Thus, ''gastrectomy'' refers to the surgical removal of the stomach (or sections thereof). "Otomy" means cutting into a part of the body; a ''gastrotonomy'' would be cutting into, but not necessarily removing, the stomach. In addition, "pharyngo" means pharynx, "laryngo" means larynx, "esophag" means esophagus. Thus, "pharyngolaryngoesophagectomy" refers to the surgical removal of the three. The field of minimally invasive surgery has spawned another set of words, such as ''arthroscopic'' or ''laparoscopic'' surgery. These take the same form as above; an arthroscope is a device which allows the inside of the joint to be seen.

Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) or gastro-oesophageal reflux disease (GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. Symptoms include dental corrosion, dysphagia, heartburn, odynophagia, regurgitation, non-cardiac chest pain, extraesophageal symptoms such as chronic cough, hoarseness, reflux-induced laryngitis, or asthma. In the long term, and when not treated, complications such as esophagitis, esophageal stricture, and Barrett's esophagus may arise. Risk factors include obesity, pregnancy, smoking, hiatal hernia, and taking certain medications. Medications that may cause or worsen the disease include benzodiazepines, calcium channel blockers, tricyclic antidepressants, NSAIDs, and certain asthma medicines. Acid reflux is due to poor closure of the lower esophageal sphincter, which is at the junction between the stomach and the esophagu ...

Esophagectomy
Esophagectomy or oesophagectomy is the surgical removal of all or parts of the esophagus. Medical uses The principal objective is to remove the esophagus, a part of the gastrointestinal tract. This procedure is usually done for patients with esophageal cancer. It is normally done when esophageal cancer is detected early, before it has spread to other parts of the body. Esophagectomy of early-stage cancer represents the best chance of a cure. Despite significant improvements in technique and postoperative care, the long-term survival for esophageal cancer is still poor. Multimodality treatment ( chemotherapy and radiation therapy) is needed for advanced tumors. Esophagectomy is also occasionally performed for benign disease such as esophageal atresia in children, achalasia, or caustic injury. In those who have had an esophagectomy for cancer, omentoplasty (a procedure in which part of the greater omentum is used to cover or fill a defect, augment arterial or portal venous c ...
