Gastric bypass surgery is often applied in cases of treatment of peptic ulcers with perforation, stenosis, bleeding or gastric cancer that systemic conditions allow. Laparoscopic gastrectomy has many advantages over traditional open surgery.

There are many forms of gastrectomy with different purposes, including the treatment of peptic ulcer disease. The doctor will perform a typical partial laparoscopic gastrectomy, removing the bottom 2/3 of the stomach and removing the pylorus.

Gastric bypass surgery is a major surgery used to treat specific diseases related to the stomach or to support weight loss and improve health. Accordingly, anesthesia is an indispensable step in total gastric bypass surgery.
