Duodenum-preserving pancreatic head resection in patients with benign and borderline tumors of the pancreatic head

Background: Benign tumors of the pancreas are rare, accounting for only 1-2% of primary pancreatic lesions. Up to now: partial duodenopancreatectomy is still one of the established forms of treatment of benign tumors of the pancreas. We applied duodenum-preserving pancreatic head resection in 12 patients with benign pancreatic tumors to evaluate the feasibility, morbidity and recurrence rates after this less aggressive method. Methods: Between April 1984 and December 1999, 12 patients with benign and borderline tumors of the pancreatic head were operated on by duodenum-preserving pancreatic head resection. Results: All five patients with serous cystadenoma are free of recurrence 4.4 years after primary resection. One of two patients with mucinous cystadenoma and one of three patients with intraductal papillary mucinous tumor developed recurrent tumor within the former pancreatic head 5 years and 6 years, respectively, after the primary operation. Both patients were resected a second time. One of two patients with gastrinoma still has elevated serum gastrin levels. There was no hospital or longterm mortality. Conclusion: For a symptomatic serous cystadenoma, duodenum-preserving pancreatic head resection is a good alternative to partial duodenopancreatectomy. In borderline tumors with malignant potential, we would rather suggest a more radical duodenum-preserving segmental resection.
