What are endoscopic measures taken in acute abdomen?

1. Gastroscopy: In case of digestive hemorrhage. In the upper GI stenosis or occlusion in the stomach or duodenum, we do gastroscopy (in this case it is diagnostic+ if there is an ulcer with bleeding, we can treat it by cauterization by injection of adrenaline). 2. Lower GI Endoscopy (Proctosigmoidoscopy): If there is a tumor in the rectum, we cannot see from above so this technique will give us a diagnosis if there is a tumor, ulcer… and at the same time if there is a sigmoid volvulus, it can make a reduction, so it will treat the sigmoid volvulus. 3. (ERCP): We use it in 2 cases: a. Angiocholitis that caused by a lithiasis inside the choledoch (common bile duct). The stone can’t pass so we do this to remove it. b. Pancreatitis (caused by calculus)
