Pancreatic head resection for noninflammatory benign lesions of the head of the pancreas.

INTRODUCTION

Duodenum-preserving pancreatic head resection (DPPHR) has been safely performed in patients with chronic pancreatitis. The procedure has rarely been used to remove benign or borderline lesions of the head of the pancreas.

AIMS

To review our experience with 13 patients who underwent DPPHR and to review reports in the literature on the same subject.

METHODOLOGY

From October 1991 to September 2000, 13 patients underwent DPPHR to resect endocrine pancreatic tumors (n = 4), beta cell hyperplasia (n = 1), pancreatic pseudocysts (n = 2), serous cystadenomas (n = 3), congenital (n = 1) and choledochal (n = 1) cysts, and intraductal papillary mucinous tumor (n = 1). The Kocher maneuver was performed in seven patients (group 1) and avoided in six (group 2). Type 1, 2, and 3 DPPHR were defined depending on the amount of pancreatic tissue left at the inner surface of the duodenum. Ten patients underwent evaluation that included an oral glucose tolerance test and exocrine pancreatic function test.

RESULTS

The mortality rate was zero; the complication rate was 69%. Patients in whom the Kocher maneuver was not performed (group 2) experienced fewer complications, shorter stay on nasogastric tube and abdominal drain(s), and earlier water intake and discharge. Type of DPPHR did not influence the postoperative course. One patient died 3 months after surgery of unrelated disease. Twelve patients were alive and well 2 months to 8 years after surgery.

CONCLUSION

DPPHR is a low-risk procedure in patients with benign or borderline noninflammatory lesions of the head of the pancreas in whom pylorus-preserving pancreaticoduodenectomy is otherwise indicated. Whenever possible, the Kocher maneuver should be avoided.
