Combined laparoscopic and thoracoscopic approach for tension gastrothorax in a foramen of Bochdalek hernia

Abstract

Introduction: The incidence of Bochdalek hernias in adults is much more than previously reported. Though most of these are asymptomatic. Tension gastrothorax is a rare complication of these. Literature about the endoscopic management of a tension gastrothorax is extremely sparse. In this case report, we describe how we combined laparoscopy and thoracoscopy in an emergency setting to manage a case of tension gastrothorax with an underlying Bochdalek hernia defect in an adult.

Patient profile: A 27 year old male presented to our emergency with tension gastrothorax and a gastric volvulus with an underlying Bochdalek hernia defect, exhibiting the classical Borchardt's triad. The patient underwent an emergency surgery, through a minimally invasive approach wherein the herniated contents were reduced, the gastric volvulus detorted and a repair of the diaphragmatic defect was performed. His post-operative course was uneventful.

Discussion: Tension gastrothorax, is a diagnostic challenge as an air-fluid level in the thorax on radiology with worsening respiration causes as many as 38% of these cases to be misdiagnosed as tension pneumothorax, hydro-pneumothorax, hemothorax, empyema, effusion or pneumonia. Various techniques of decompression have been described in literature but, employing those, in case of a misdiagnosis may have catastrophic outcomes.

Conclusion: We strongly recommend employing a combined laparoscopic and thoracoscopic approach for an emergency repair of a tension gastrothorax in a hemodynamically stable patient as, it poses all the advantages of minimal access surgery and is available, at smaller centres, even in an emergency.
