Background <p>Morgagni hernia is a relatively rare type of diaphragmatic hernia, accounting for approximately 3% to 4% of all congenital diaphragmatic hernias. Currently, imaging studies play a crucial role in determining the location, size, and characteristics of the diaphragmatic defect and the herniated contents. Once diagnosed, surgical intervention should be the standard treatment. This study aims to share our experience with five cases of surgical treatment for Morgagni hernia, providing a reference for clinical practice.</p> Methods <p>We collected relevant clinical and imaging data from five patients who underwent laparoscopic-assisted suture hook technique for Morgagni hernia at our institution.</p> Results <p>Among the five patients treated with laparoscopic-assisted suture hook technique, 60% were male, and all cases were on the right side, with a mean age of 59.4 years. Eighty percent of the patients were overweight or obese, with a mean BMI of 26.03. All patients presented with symptoms, with the most common being chest pain and upper abdominal pain. The most common herniated content was the omentum (100%), followed by the transverse colon (60%). The average surgical duration was 57.6 minutes, and the mean intraoperative blood loss was 8 ml. All patients retained the hernial sac, and no drainage tubes were placed during the surgery. The average postoperative hospital stay was 2.8 days. The average follow-up period post-discharge was 10 months, during which all symptoms resolved, and there were no recurrences.</p> Conclusion <p>Laparoscopic-assisted suture hook technique for the repair of Morgagni hernia is a safe and feasible surgical approach. It is characterized by short operative time, minimal trauma, rapid postoperative recovery, and low recurrence rates. Additionally, this surgical technique is simple and easy to learn, with relatively low requirements for laparoscopy suturing and knot-tying skills.</p>
