Abstract

Introduction: A diaphragmatic hernia (DH) is a defect within a part of the diaphragm that allows intra-abdominal contents to enter the thoracic cavity. Diaphragmatic hernias can be congenital or acquired later in life. The most common congenital DH is the Bochdalek hernia (posterolateral hernia), but the most commonly acquired DH is due to traumatic injury. These hernias are rare in adults and are typically diagnosed incidentally. Surgical repair is the standard of care; however, data regarding the surgical approach is scarce. We report a case of a rare right posterolateral DH in an adult female patient who presented with acute abdominal pain.

Case presentation: A 69-year-old female presented with recurrent epigastric pain that had acutely worsened, nausea, vomiting, and food intolerance. A computed tomography (CT) scan demonstrated a right posterolateral DH containing the hepatic flexure of the colon. The patient was taken urgently to surgery due to concern for strangulation. Reduction of the hernia was attempted laparoscopically but was converted to an open procedure with a subcostal incision due to poor visualization. This approach revealed adequate exposure of the defect and subsequent reduction of the herniated abdominal contents. The defect was easily closed without tension or the use of mesh. The patient was discharged on postoperative day 3.

Conclusion: Chronic DH can have severe life-threatening sequelae when left untreated. This case demonstrates the importance of thorough history-taking and raises awareness of missed diaphragmatic injuries in trauma situations. Since patients who present with a symptomatic DH often need urgent repair, it is important for surgeons working in the acute care setting to understand the surgical options available and when mesh placement may benefit the situation. Our case outlines a successful primary defect repair, without mesh, of a right-sided DH in which a minimally invasive technique was attempted but converted to laparotomy for patient safety.
