A gastrojejunostomy involves the surgical creation of a new connection, or anastomosis, between the stomach and the jejunum, the middle section of the small intestine. This procedure redirects the flow of food from the stomach to the jejunum, bypassing the duodenum, which is the initial portion of the small intestine. In some cases, the term “gastrojejunostomy” may also be used to refer to a minor intervention for placing a feeding tube in the small intestine, known as a gastrojejunostomy tube. This tube, passing through the stomach and duodenum, facilitates nutrition delivery directly to the jejunum, a procedure distinct from percutaneous gastrojejunostomy.
A gastrojejunostomy may be necessary if your duodenum or lower stomach (antrum) faces medical issues, such as blockages or dysfunction. In cases where the outlet at the bottom (pylorus) hinders food passage, connecting the small intestine to the upper part of the stomach through gastrojejunostomy can provide a solution. Additionally, gastrojejunostomy is a component of weight loss surgery, exemplified by the Roux-en-Y gastric bypass, where a portion of the stomach and the duodenum are bypassed to reduce food capacity in the stomach and limit nutrient absorption in the small intestine.
Gastrojejunostomy may be recommended for the treatment of various conditions:
Less commonly, a preventative gastrojejunostomy may be performed in the following situations:
Surgical procedures, including gastrojejunostomy, involve inherent risks like bleeding, blood clots, organ damage, and excessive internal scar tissue formation. In the case of gastrojejunostomy, there is an additional risk of anastomotic leak, a rare occurrence where fluids may escape from the newly established connection between the stomach and intestines. This leakage poses the potential for abdominal infections, and if it extends to the bloodstream, it could trigger a severe and life-threatening reaction known as sepsis.
Possible long-term side effects of gastrojejunostomy include:
It’s crucial to note that these long-term side effects are potential complications that may arise, and individual experiences can vary. Patients should thoroughly discuss the risks and benefits of the procedure with their healthcare providers before making informed decisions about surgery.
Before undergoing surgery, your healthcare team will assess your overall health, especially if you’re experiencing conditions such as gastrointestinal tract blockages. Common symptoms may include difficulty keeping food down, frequent vomiting, dehydration, and malnourishment.
To optimize your health for surgery, your healthcare team may administer the following treatments:
The gastrojejunostomy procedure typically involves the following steps:
The gastrojejunostomy procedure typically lasts between two to four hours.
After the surgery, you’ll be hospitalized, and it may take some time before you can tolerate solid food. You might experience nausea or delayed bowel movements (paralytic ileus). Additionally, the stomach might empty slowly through the new connection, and some individuals may require a nasogastric tube for several days. Initially, you may receive IV fluids and nutrition, or you could begin with a clear liquid diet, gradually transitioning to a soft diet before discharge. In certain instances, it may take several weeks for your stomach to regain normal function post-surgery, necessitating continued tube or IV feeding.
Recovery duration: The average recovery time after surgery typically spans around six weeks. However, this duration may vary depending on the extent of your surgical procedure and whether it was performed using open or laparoscopic techniques. In some cases, the surgery may involve the division or removal of a portion of your stomach and small intestine. For patients undergoing surgery for cancer, additional tissue removal may have been necessary.
Postoperative care: Your healthcare team will provide you with essential instructions for caring for your incision wounds, managing pain at home, and determining when you can resume your regular activities. A follow-up appointment with your healthcare provider will be scheduled a few weeks after you are discharged to monitor your recovery progress and identify any potential complications.
Dietary considerations: Following surgery, you may be required to adhere to a special diet for several months. The specifics of this diet will depend on the extent of stomach and/or intestine removal and whether you are experiencing symptoms of dumping syndrome. It may necessitate heightened attention to your nutritional intake, including the possible use of vitamin supplements, and the avoidance of high-sugar foods.
You should promptly get in touch with your healthcare team if you encounter any of the following issues:
Your health and well-being are of utmost importance, and timely communication with your healthcare professionals is crucial to ensure a smooth recovery process.
