title: Multiparametric evaluation of functional outcome after pylorus-preserving duodenopancreatectomy.
abstract: The aim of the present study was to evaluate the clinical, morphological and functional results obtained in a group of patients previously submitted to Traverso-Longmire pylorus-preserving duodeno-pancreatectomy (PPDP). The study was performed as a clinical, endoscopic, radioisotopic and electro-manometric evaluation. An analysis of the results allowed us to conclude that: 1) most patients show good clinical features, and this becomes more evident as post-operative time progresses; 2) bile reflux gastritis is an infrequent event; 3) gastric emptying times in patients overlap those seen in control subjects, and progressive normalization occurs postoperatively. The best clinical results coexist with normal gastric emptying times; 4) gastrojejunal interdigestive motor activity shows a reduction in phase 3 and a relative increase in phase 2. We argue that the motor activity of the upper gastrointestinal tract can restore, from a functional point of view, the new anatomical situation. On the basis of the good clinical and functional results, pyloric preservation seems to be the most physiological procedure for the restoration of alimentary continuity following duodenopancreatic resection.
