Gastrojejunostomy is a procedure that creates a connection between the stomach and the jejunum, the middle portion of the small intestine. The new pathway allows food and stomach contents to bypass the duodenum or an obstructed gastric outlet. It can be performed as a stand-alone bypass or as part of another gastrointestinal operation. Surgical gastrojejunostomy can be created with an open, laparoscopic, or robotic approach.
read more about gastrojejunostomy ...Gastrojejunostomy is commonly used to bypass gastric outlet obstruction caused by pancreatic cancer, gastric cancer, chronic pancreatitis, scarring, or selected other conditions. It can restore the ability to eat when food cannot pass normally from the stomach into the duodenum. The connection is also incorporated into procedures such as gastric bypass and some pancreatic or gastric operations. Endoscopic stenting or endoscopic ultrasound-guided bypass can be alternatives in selected patients, especially when the goal is palliation and major surgery carries high risk.
The surgeon identifies a suitable portion of the stomach and brings a loop of jejunum into position without excessive tension or twisting. Openings are created in the stomach and jejunum, and the two are joined with sutures, surgical staples, or both. The anastomosis can be placed in an antecolic or retrocolic position depending on the operation and anatomy. The surgeon checks the connection for adequate blood supply, a patent opening, and signs of leakage before completing the procedure.
Patients are monitored for pain, nausea, vomiting, bowel function, hydration, and signs that the stomach is emptying through the new connection. Oral intake is advanced gradually when the surgical team determines that gastrointestinal function is returning. Recovery time depends on whether the procedure was open or minimally invasive and whether cancer surgery or another major operation was performed at the same time. Nutritional support can be required when illness, cancer, or prolonged obstruction has caused substantial weight loss.
Possible complications include bleeding, infection, anastomotic leak, delayed gastric emptying, bowel obstruction, ulceration, and injury to nearby organs. The connection can later narrow or become obstructed by scar tissue, recurrent cancer, or other disease. Bile reflux, marginal ulceration, and nutritional problems can occur depending on the reconstruction and underlying condition. Patients with advanced cancer can also develop recurrent obstruction elsewhere in the gastrointestinal tract despite a functioning bypass.
No. Gastrojejunostomy describes the stomach-to-jejunum connection itself. Gastric bypass is a bariatric operation that uses a gastrojejunostomy as part of a larger reconstruction.
Yes. Selected patients can undergo laparoscopic or robotic gastrojejunostomy instead of an open operation.
Not necessarily. It commonly bypasses the obstructed area so food can travel through an alternate route. The original blockage can remain in place.
Yes. Scar tissue, ulceration, recurrent disease, or tumor growth can narrow the connection and cause recurrent vomiting or difficulty eating.
