Pylorus-preserving pancreatoduodenectomy. A clinical and physiologic appraisal.
Since 1978, 252 patients from different centers in the world have undergone pylorus-preserving pancreatoduodenectomy. Fifty-five per cent of the patients had malignant tumors in the region of the head of the pancreas. The overall operative mortality rate was 2.8%. Anastomotic leakage and fistulae occurred in 19% of the patients. Pancreatic, biliary, and enteric fistulae represented 11%, 4%, and 4%, respectively. Peptic ulcers were subsequently diagnosed in seven patients (3%), two of whom required vagotomy and antrectomy. Delayed recovery of gastric function was the most common complication of this operation, with an overall incidence of 30%. Although the cause of this gastric dysfunction is unknown, its transient nature in most patients makes expectant therapy with gastric tube drainage the best remedy when the problem is encountered. Pylorus-preserving pancreatoduodenectomy decreased the incidence of postgastric surgery syndromes that are commonly associated with the standard Whipple operation. The existing data support the continued use of the operation and the need for future laboratory and clinical investigation of its physiologic impact.
