The case

A gastrojejunostomy joins the stomach to the jejunum, the first long stretch of small bowel. It has three main uses: getting food around a blockage at the outlet of the stomach or in the duodenum (from cancer or ulcer scarring), rebuilding the gut after part of the stomach is removed for cancer, and weight-loss surgery, where it is the key connection in a Roux-en-Y gastric bypass. Proximal Roux-en-Y gastric bypass is the second most common weight-loss operation in Europe, after the sleeve gastrectomy, and this page follows a published da Vinci Xi technique for it.

In a gastric bypass, the top of the stomach is made into a small pouch. A loop of jejunum is joined to the pouch, so food skips most of the stomach and the first part of the small bowel. The bypassed part is joined back to the bowel farther down so its digestive juices still flow. The robot helps most with the thick belly wall of a very heavy patient: its arms hold the ports steady, and the surgeon works from a console in the room with a 3D view. The connections can be made in several ways, and studies find them about equally safe. A simpler loop gastrojejunostomy, without the second connection, may be done just to get around a blockage.

The operation is long, is done under general anesthesia, and the patient stays in the hospital afterward. Patients are asked to get up and walk on the day of surgery. The most feared problem is a leak at the connection, which usually shows up on the third to fifth day, often first as a fast heart rate. Bleeding, blood clots, bowel blockage, internal hernia through gaps in the bowel's attachments (such as the Petersen space), ulcers at the connection, dumping syndrome and vitamin or nutrient shortfalls can also occur. The robotic approach adds cost and setup time compared with standard keyhole surgery.
