Gastrothorax: A case of mistaken identity

Acute wrap failure post fundoplication is a rare but recognized complication and can be due to patient factors, disease factors and surgical factors. Herniation of the stomach into the thorax can mimic a pneumothorax clinically and radiologically and thus lead to bad outcomes for patients.

We report the case of a 20-year-old male who presented to the emergency department with progressively worsening upper abdominal pain, nausea and vomiting followed by acute onset dyspnoea, six days post a laparoscopic repair of a small hiatus hernia and a Nissen fundoplication. His chest x-ray was consistent with that of a left sided pneumothorax and was therefore, appropriately resuscitated and treated with an intercostal catheter (ICC). A subsequent CT scan of the chest revealed a left gastrothorax. The patient was taken to theatre for the surgical reduction of the paraoesophageal hernia.

Patients with a recent history of anti-reflux surgery, who present with a pneumothorax and respiratory distress or a tension pneumothorax should always be treated with an ICC. However, follow up imaging with a CT scan is essential to confirm diagnosis. Good control of post- operative nausea and vomiting is essential in avoiding wrap failure and ensuing complications.

A high index of suspicion for a gastrothorax mimicking a pneumothorax is important in the setting of recent anti-reflux surgery.
