A Billroth II procedure refers to which type of surgery?

The Billroth II procedure specifically involves a gastrojejunostomy, which is a surgical technique performed in cases such as peptic ulcer disease or gastric cancer. In this procedure, the stomach is reconnected to the jejunum, bypassing a portion of the duodenum. This is typically done after a partial gastrectomy, where a segment of the stomach is removed.

In contrast, gastroduodenostomy refers to the direct connection between the stomach and the duodenum, while total gastrectomy involves the complete removal of the stomach along with anastomosis to another part of the gastrointestinal tract. Biliopancreatic diversion is a more complex weight-loss surgery that involves a significant alteration of the gastrointestinal system and is not represented by the Billroth II procedure.

Thus, the correct identification of the Billroth II as a gastrojejunostomy highlights its specific nature and purpose in surgical practice.
