Minimally Invasive Surgical Approach for Adult Morgagni Hernia Repair Using Mesh Reinforcement

Morgagni hernia represents a rare anterior diaphragmatic defect, accounting for approximately 2-3% of all congenital diaphragmatic hernias, presenting unique surgical challenges in adult patients. A 63-year-old female presented with right hypochondrial pain and respiratory symptoms. Computed tomography revealed herniation of the omentum and transverse colon through a right-sided anteriomedial diaphragmatic defect measuring 4×4 cm. The surgical repair was performed laparoscopically using a three-port technique under general anesthesia. The hernia contents were reduced, and the defect was primarily closed using V-lock sutures, reinforced with a 15×15 cm composite mesh. The postoperative course remained uneventful, with complete resolution of symptoms and no recurrence at six-month follow-up. The laparoscopic approach demonstrated significant advantages, including excellent visualization of the surgical field, reduced postoperative pain, shorter hospital stay, and rapid recovery. Early diagnosis and surgical intervention are crucial to prevent potential complications such as incarceration or strangulation of herniated contents. The successful outcome highlights the efficacy of minimally invasive techniques in managing adult Morgagni hernias.
