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.
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.
Roux-en-Y hepaticojejunostomy or choledochojejunostomy with gastrojejunostomy as palliation for irresectable pancreatic head cancer. [8] References
Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed.
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.
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.
A gastrojejunostomy, or GJ feeding tube, is a combination device that includes access to both the stomach and the jejunum, or middle part of the small intestine. Typical tubes are placed in a G-tube site or stoma, with a narrower long tube continuing through the stomach and into the small intestine.
The loop should be long enough and should have a Braun jejunojejunostomy between the ascending and the descending loop. [9] The last 4 to 5 cm of the stapler line towards the greater curvature should be excised with the help of an electrocautery device in order to form a slim opening for the subsequent gastrojejunostomy.
