Postprandial hypoglycemia after Nissen fundoplication for reflux esophagitis.

The motility of the stomach is modulated by the complex interplay of muscular, humoral, and neuronal factors. Rapid gastric emptying has been described after gastrectomy, gastrojejunostomy, vagotomy with pyloroplasty, and with active peptic ulcer disease. Rapid emptying may result in "dumping" syndrome and in postprandial hypoglycemia. We report a patient who developed postprandial hypoglycemia after a Nissen fundoplication for reflux esophagitis. This is the first report of this complication after this surgical procedure. The hypoglycemia was secondary to a combination of rapid gastric emptying, rapid absorption of glucose causing hyperglycemia, and excessive insulin secretion. This syndrome should be considered in patients who develop hypoglycemic symptoms after fundoplication. Treatment with a low carbohydrate diet and anticholinergic agents may offer symptomatic relief.
