What surgical procedure involves the removal of the distal stomach and antrum with an anastomosis to the jejunum?

The procedure that involves the removal of the distal stomach and antrum, along with creating an anastomosis to the jejunum, is gastrojejunostomy. This surgical technique is used primarily to treat conditions that require bypassing the stomach, often to facilitate food passage following resection due to issues like gastric cancer or severe ulcers.

In this procedure, after resection of the distal stomach, the remaining stomach is directly connected to the jejunum, which helps in bypassing the duodenum. This approach is instrumental in minimizing complications associated with gastric outlet obstruction, as it allows food to move from the remaining stomach into the jejunum without passing through the duodenum.

Other surgical options listed, such as Billroth I, pyloroplasty, and vertical sleeve gastrectomy, do not entail this specific combination of actions. Billroth I primarily involves the removal of the distal stomach but reconnects the stomach to the duodenum, not the jejunum. Pyloroplasty is a less extensive procedure that widens the pylorus without resection, and vertical sleeve gastrectomy involves resection but doesn't include connection to the jejunum directly. Thus, the definition and objectives of gastrojejunostomy specifically align
