Which procedure is characterized by partial gastrectomy with jejunal anastomosis?

The procedure characterized by partial gastrectomy with jejunal anastomosis is known as Billroth II. This surgical technique involves the removal of a portion of the stomach (partial gastrectomy) followed by the connection of the remaining portion of the stomach to the jejunum, which is part of the small intestine.

In Billroth II, the proximal part of the jejunum is attached to the stomach, allowing for the passage of food directly into the jejunum, bypassing the duodenum. This is typically performed in cases of peptic ulcer disease or gastric cancer when a resection is necessary, and it facilitates digestion by allowing for a new passageway for the contents to travel into the intestines.

On the other hand, Billroth I involves direct anastomosis of the stomach to the duodenum, not the jejunum, which differentiates it from Billroth II. Cecostomy and ileal conduit are unrelated surgical procedures involving the colon and urinary system, respectively, and do not pertain to the operations involving gastrectomy and jejunal anastomosis.
