A case report: Liraglutide as a novel treatment option in late dumping syndrome.

RATIONALE: Postprandial hyperinsulinemic hypoglycemia, known as late dumping syndrome, is a rare but often misdiagnosed complication after gastric surgery. The pathophysiological mechanisms are poorly understood and the treatment of this syndrome is challenging. PATIENT CONCERNS: New-onset postsurgical late dumping syndrome after Toupet fundoplication. DIAGNOSES: Sigstad Score, OGTT, CGM. INTERVENTIONS: Daily subcutaneous injection of liraglutide (0.6 mg and 1.2 mg). OUTCOMES: Reduction in fasting and postprandial peak insulin level with improvement in symptomatic hypoglycemic events. LESSONS: Liraglutide may be a novel treatment option for postprandial hyperinsulinemic hypoglycemia after gastric surgery.
