title: [Peptic ulcer: late complications of the surgical treatment].
abstract: The incidence of surgical treatment of peptic ulcer decreased in the last two decades. The majority of procedures for surgical management of peptic disease impairs the ability of the stomach to receive and to store food. The intake of high protein-caloric content diets can improve some nutritional deficits expressed by loss of body weight and anemia. The mechanism responsible for diarrhea is unknown, but truncal vagotomy has the highest incidence. It is usually episodic, lessens over the first year after operation and rarely remains a severe problem. The decreasing levels of colecistokinin response after meal in gastrectomy and the division of hepatic branch of anterior vagus can cause gallbladder sludge and stone formation. Alkaline reflux explains gastritis and esophagitis after partial gastric resection. Surgical duodenal diversion, like a Roux-en-Y limb, have been successful in its control. The mechanism that leads to the dumping syndrome are loss of gastric reservoir function and rapid emptying of hyperosmolar meals into small intestine. Somatostatin analogues improve the symptoms caused by abnormal release of neurohormonal agents responsible of the behaviour of the gastrointestinal tract after meals. Cancer of gastric remanent may be due to increased bacterial overgrowth and nitrosation formation. The endoscopic follow-up is essential for early diagnosis of the stump cancer. In spite of all complications, the surgeon cannot have hesitations by carrying out radical approach meanly during catastrophic emergencies of peptic disease i.e. in elderly aged patients. Nowadays, the control of chronic sequelas is easy with conservative therapeutic.
