Which surgical procedure involves a connection between the stomach and jejunum?

The procedure that establishes a connection between the stomach and the jejunum is the Billroth II procedure. This particular surgery involves removing part of the distal stomach (the pylorus) and then connecting the remaining stomach directly to the jejunum, which is the second part of the small intestine. This creates a more direct pathway for food to travel from the stomach into the intestines, bypassing the duodenum.

Billroth II is commonly performed in cases of peptic ulcer disease, where significant parts of the stomach may need to be resected due to ulceration. By directly connecting the jejunum to the stomach, the procedure effectively manages complications associated with ulcer disease and promotes a more efficient digestive process.

The other procedures listed do not involve creating a connection between the stomach and jejunum. Vagotomy involves cutting the vagus nerve to reduce gastric acid secretion and is typically performed in conjunction with drainage procedures but does not create a direct connection between these two regions. An incarcerated hernia repair addresses a hernia and does not involve the stomach or jejunum specifically. Fissure correction pertains to the treatment of anal fissures and is unrelated to gastrointestinal bypass or connections.
