Gastric bypass surgery. Surgeon using endoscopic equipment during laparoscopic gastric bypass surgery on an obese patient. The endoscopes are inserted through holes in the abdomen to view and operate on the internal organs. In gastric bypass surgery the size of the stomach is reduced to make the patient feel full after eating less food. The surgery also involves reconstructing the intestines to reduce the amount of food absorbed by the patient. Photographed in a UK hospital in 2014.
