Post−Gastric Bypass Hyperinsulinism With Nesidioblastosis: Subtotal or Total Pancreatectomy May Be Needed to Prevent Recurrent Hypoglycemia

Clancy, Thomas E., Moore, Francis D., Zinner, Michael J.·2006·Journal of Gastrointestinal Surgery

Abstract

Symptomatic hyperinsulinemic hypoglycemia and pancreatic nesidioblastosis have recently been described in a small series of patients after gastric bypass surgery for morbid obesity. In the limited published reports of patients with this condition, hyperinsulinism and nesidioblastosis have been managed with distal or subtotal pancreatectomy, with the extent of resection guided by calcium angiography. However, nesidioblastosis may involve the pancreas diffusely, and limited pancreatic resections may predispose patients to further hypoglycemic episodes. We have treated two patients with refractory hyperinsulinism and symptomatic hypoglycemia after successful gastric bypass surgery. One patient underwent an approximately 80% pancreatectomy with good results but subsequently experienced recurrent drop attacks and fainting from hyperinsulinism; a completion pancreatectomy via a pancreaticoduodenectomy was then required. A second patient had profound hyperinsulinemic hypoglycemia and was treated successfully with a subtotal (95%) pancreatectomy. Our experience, the third published report of post-gastric bypass nesidioblastosis, suggests that the risk of recurrent symptomatic hyperinsulinism after limited pancreatectomy is significant and relative euglycemia may be achieved with subtotal or total pancreatectomy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
