Pancreatic head resection and Roux-en-Y pancreaticojejunostomy for the treatment of the focal form of congenital hyperinsulinism

Abstract

Purpose: To determine the outcome of patients who underwent pancreatic head resection and Roux-en-Y pancreaticojejunostomy to the remaining normal pancreatic body and tail for the treatment of a focal lesion in the pancreatic head causing congenital hyperinsulinism (HI).

Methods: One hundred thirty-eight patients underwent pancreatic resection for focal HI between 1998 and 2010. Twenty-three patients in the group underwent pancreatic head resection and Roux-en-Y pancreaticojejunostomy.

Results: There were 13 females and 10 males. Median age and weight at surgery were 8 weeks and 5.8 kg, respectively. Twenty-one patients had a near-total pancreatic head resection, and 2 patients had a pylorus-preserving Whipple procedure. The pancreaticojejunostomy anastomosis was performed with interrupted fine monofilament sutures such that the transected end of the pancreatic body was tucked within the end of the Roux-en-Y jejunal limb. Median hospital stay was 22 days. All patients were cured of HI.

Conclusion: We conclude that pancreatic head resection with Roux-en-Y pancreaticojejunostomy is a safe and effective procedure for the treatment of the HI patient with a large focal lesion in the pancreatic head that is not amenable to local resection alone.
