Long-term outcome after 92 duodenum-preserving pancreatic head resections for chronic pancreatitis: comparison of Beger and Frey procedures.

INTRODUCTION

Duodenum-preserving pancreatic head resection may be an alternative to pancreatoduodenectomy or drainage procedures for chronic pancreatitis. There are few studies directly comparing the long-term outcome after the operations described by Beger and Frey.

METHODS

One hundred thirteen patients underwent duodenum-preserving pancreatic head resection for complications of chronic pancreatitis. Follow-up was obtained in 92 patients (42 Beger, 50 Frey, median follow-up almost 5 years).

RESULTS

Overall/surgery-related perioperative morbidity was 30%/20% (Frey) and 40%/31% (Beger). In long-term follow-up (Frey vs Beger), 62% vs 50% were completely free of pain, but 6% vs 19% had pain at least once per week or daily, and 32% vs 31% experienced pain attacks at least once per year (n.s.). Diabetes mellitus occurred in 60% vs 57% (de novo 34% vs 17%). Rates of exocrine insufficiency were 76% vs. 74% (de novo 34% vs. 33%). Median gain in body weight was 2.5 vs 1.5 kg (n.s.), respectively. Four patients had clinically relevant biliary complications during follow-up requiring reintervention.

CONCLUSIONS

Our (nonrandomized) comparison of the long-term outcome after Frey and Beger procedures for chronic pancreatitis reveals a tendency for better pain control with the Frey operation. The functional outcomes were almost identical.
