Surgery for chronic obstructive pancreatitis: comparison of end-to-side pancreaticojejunostomy with pancreaticoduodenectomy.

BACKGROUND/AIMS: Chronic obstructive pancreatitis usually manifests with intractable pain and recurrent episodes of chronic pancreatic inflammation. The side-to-side pancreaticojejunostomy is used for those patients with a large pancreatic duct. But for the patients with small pancreatic duct, the optimal surgical procedure needs to be evaluated. A prospective study was designed to compare the different results between distal pancreatectomy plus end-to-side pancreaticojejunostomy and pancreaticoduodenectomy.

METHODOLOGY: The patients were chosen prospectively and randomly to undergo either a distal pancreatectomy plus end-to-side pancreaticojejunostomy or pancreaticoduodenectomy in the last 3 years. Eighteen patients with chronic obstructive pancreatitis were randomly divided into two groups. Ten patients (group A) underwent distal pancreatectomy plus end-to-side and ductal to mucosal pancreaticojejunostomy, and the other 8 patients (group B) underwent pancreaticoduodenectomy were compared.

RESULTS

The operative time was significantly shorter and operative blood loss was less in group A. The postoperative follow-up of patients in group A had better outcome with increased body weight and no steatorrhea or diabetes mellitus, and all of them had complete pain relief.

CONCLUSIONS

We concluded that distal pancreatectomy with end-to-side pancreaticojejunostomy provided a better surgical treatment for the patients with chronic obstructive pancreatitis and small pancreatic duct.
