A Delayed Presentation of Late Dumping Syndrome After Ivor Lewis Procedure

An accurate and timely diagnosis of dumping syndrome after gastric and oesophageal surgery is often difficult. A delay in making this diagnosis and instituting therapy can result in significant morbidity and avoidable complications. As bariatric surgery becomes more prevalent, the importance of a timely diagnosis of dumping syndrome is increasing. We present a case of a 77-year-old man who was admitted into the intensive care unit with a reduced conscious state secondary to hypoglycemia. The patient was subsequently diagnosed with late dumping syndrome in the context of an Ivor Lewis procedure seven years prior. Despite having a history of recurrent neuroglycopenic symptoms, there was a delay in diagnosis as dumping syndrome had not previously been considered until this admission. After confirmation of the diagnosis, the patient was commenced on dietary adjustments and acarbose, with a resolution of post-prandial hypoglycaemia. The authors discuss dietary and pharmacological therapy to manage hypoglycaemia associated with dumping syndrome.
