Jejunojejunostomy is a surgical technique used in an anastomosis between two portions of the jejunum. [1] It is a type of bypass occurring in the intestine . It may lead to marked reduction in the functional volume of the intestine.
Radiation enteritis and scarring from marginal gastrojejunostomy ulceration are the causes of mechanical blockage of the intramural area. [7] [8] Conditions that cause external compression include internal hernia, volvulus, entrapment, compression, kinking of the afferent loop, postoperative adhesion, and intussusception of the afferent loop.
In addition, other side effects include dysphagia, which is when digestive juices in the duodenum flow upward to the esophagus, thus esophageal lining is irritated. Diarrhea is common, especially in patients who had vagotomy in addition to an antrectomy because the damage of nerves to the liver and gallbladder causes excess bile salt release.
The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis. The Billroth II always follows resection of the lower part of the stomach . The surgical procedure is called a partial gastrectomy and gastrojejunostomy.
Jejunostomy is the surgical creation of an opening (stoma) through the skin at the front of the abdomen and the wall of the jejunum (part of the small intestine).It can be performed either endoscopically, or with open surgery.
Numerous studies show that the loop reconstruction (Billroth II gastrojejunostomy) works more safely when placed low on the stomach, but can be a disaster when placed adjacent to the esophagus. Today thousands of "loops" are used for surgical procedures to treat gastric problems such as ulcers, stomach cancer, and injury to the stomach.
But some research has noted rare but serious side effects of once-weekly, 2.4-milligram (mg) semaglutide injections, such as pancreatitis, acute kidney injury, gallbladder issues, and thyroid cancer.
Roux-en-Y reconstruction following partial or complete gastrectomy for stomach cancer. [4] Roux-en-Y hepatico jejuno stomy used to treat (macroscopic) bile duct obstruction which may arise due to: a common bile duct tumour or hepatic duct tumour (e.g. resection of cholangiocarcinoma) [5] a bile duct injury (e.g. cholecystectomy, iatrogenic, trauma)
