Bochdalek Hernia in an Adult Causing Intraoperative Complication

Bochdalek hernias are rarely diagnosed in adults and account for 0.17-6% of all diaphragmatic hernias. It is a congenital diaphragmatic hernia caused by a defect in the posterior attachment of the diaphragm due to a failure of the pleuroperitoneal membrane closure in utero. This may rarely cause chest pain, respiratory symptoms, or gastrointestinal symptoms. In this study, we present a case of a laparoscopic paraesophageal repair via Nissen fundoplication. The incidental finding and subsequent repair of a Bochdalek hernia during this case may have resulted in complications of the surgery including pneumothorax due to the defect in the pleuroperitoneal membrane.
