[Digestive physiopathology of the pancreatectomized patient. Comparison of the results of total pancreatectomy and pancreaticoduodenectomy with preservation of the pylorus].

The authors analyze their experience with pancreatectomy, pointing out the digestive pathophysiologic sequelae of the operated patients. A follow-up protocol based on upper digestive endoscopy, laboratory tests, scintigraphic and pH-metric tests compares the results achieved after total pancreatectomy with the results of pancreaticoduodenectomy. Total pancreatectomy is complicated by peptic ulcer, stump gastritis and gastroenteric dyskinesia. The preservation of the pylorus and the separation of the gastric anastomosis from the biliary one avoid the pathologic biliary reflux and minimize the functional and organic sequelae of the operation.
