Original publication title: Successful Repair of a Morgagni Hernia Using the Laparoscopic Transabdominal Preperitoneal (TAPP) Approach: A Case Report.
Plain-English summary
A Morgagni hernia is a rare type of hernia that occurs in the diaphragm. In this case, a 76-year-old woman found out she had this hernia while being checked for a knee surgery. Doctors used a special minimally invasive technique to repair it, placing a mesh to support the area without touching the organs inside her abdomen. After the surgery, she recovered well and went home five days later, and there have been no signs of the hernia coming back after ten months. This method seems to be a safe and effective way to treat Morgagni hernias.
Abstract
Morgagni hernia (MH) is a rare diaphragmatic hernia caused by a parasternal defect. We report a case of MH that was successfully repaired using a laparoscopic transabdominal preperitoneal (L-TAPP) approach combined with a self-gripping mesh. A 76-year-old woman was incidentally diagn4osed with MH during a preoperative evaluation of an unrelated knee surgery. Computed tomography revealed herniation of the greater omentum through a diaphragmatic defect measuring ~5 cm × 5 cm. L-TAPP was performed, in which the hernia contents were reduced and wide peritoneal dissection enabled tension-free mesh placement in the extraperitoneal space using a self-gripping mesh. The postoperative course was uneventful, and the patient was discharged on postoperative Day 5, with no recurrence observed at 10 months of follow-up. The L-TAPP approach allows secure mesh placement without direct contact with the intra-abdominal organs, potentially reducing the risk of recurrence and intraperitoneal complications. L-TAPP combined with a self-gripping mesh may be a useful and minimally invasive treatment option for MH.
