Abstract

Purpose: Recurrent severe hypoglycemic attacks often persist even after performing pancreatectomy for medically unresponsive congenital hyperinsulinism (CHI). In this study, we present our experience with redo pancreatectomy for CHI.

Methods: We reviewed all children who underwent pancreatectomy for CHI between January 2005 and April 2021 in our center. A comparison was made between patients whose hypoglycemia was controlled after primary pancreatectomy and patients who required reoperation.

Results: A total of 58 patients underwent pancreatectomy for CHI. Refractory hypoglycemia after pancreatectomy occurred in 10 patients (17%), who subsequently underwent redo pancreatectomy. All patients who required redo pancreatectomy had positive family history of CHI (p = 0.0031). Median extent of initial pancreatectomy was lesser in the redo group with borderline level of statistical significance (95% vs. 98%, p = 0.0561). Aggressive pancreatectomy at the initial surgery significantly (p = 0.0279) decreased the risk for the need to redo pancreatectomy; OR 0.793 (95% CI 0.645-0.975). Incidence of diabetes was significantly higher in the redo group (40% vs. 9%, p = 0.033).

Conclusion: Pancreatectomy with 98% extent of resection for diffuse CHI, especially with positive family history of CHI, is warranted to decrease the chance of reoperation for persistent severe hypoglycemia.
