Minimally Invasive Repair Options for Symptomatic Larrey Hernia in an Adult: A Case Report and Literature Review

Morgagni-Larrey hernias (MLH) are rare congenital anterior diaphragmatic defects, and Larrey hernias are a less common variant that typically occurs on the left side. Their rarity and often asymptomatic nature in adults make diagnosis and treatment challenging. A 44-year-old woman experienced intermittent left upper quadrant abdominal pain for one year, with associated nausea and vomiting. Her past medical history included a laparoscopic cholecystectomy and a right inguinal hernia repair. Imaging confirmed a left-sided anterior diaphragmatic defect consistent with a Larrey hernia. Laparoscopic surgery revealed herniation of omentum and colon, which was repaired with primary suture closure and polypropylene mesh reinforcement. The patient remained asymptomatic, with radiographic confirmation of repair and no recurrence at five months. This case highlights the importance of considering MLH in adults with nonspecific gastrointestinal symptoms. Early diagnosis and surgical intervention are key to preventing complications such as bowel obstruction and respiratory compromise.
