A rare case of multiple port site incisional hernias repaired by laparoscopy-assisted intraperitoneal onlay mesh: A case report.

introductionPort site herniation is a frequent complication of abdominal surgery, yet treatment strategies for multiple port site hernias are often difficult and case reports are rare. PRESENTATION OF CASE: A 72-year-old woman, with a history of multiple abdominal surgeries, underwent laparoscopic surgery for rectal prolapse four years prior. Three 12 mm ports were inserted into the umbilical region, right upper quadrant and right lower abdomen, subsequently, incisional hernias developed at all three sites. In addition, an incisional hernia developed in the lower abdomen, for a total of four incisional hernias. She was taking apixaban for atrial fibrillation, and since the standard surgical method of placing the mesh in the extraperitoneal space was judged to be high risk for postoperative bleeding and hematoma formation, we performed a laparoscopy-assisted intraperitoneal onlay mesh repair (IPOM). DISCUSSION: The key points of the surgery performed are: Laparoscopic surgery was initiated with a small incision in the umbilical region, using two 5 mm ports because we reasoned that using a 12 mm port could cause a new hernia. In the lateral hernia repair, a mesh was placed in the preperitoneal space on the dorsal side of the hernia, the mesh was sutured to the peritoneum because tucking cannot be performed if nerves are present on the dorsal aspect. The medial hernia was repaired by IPOM via a small laparotomy incision.

conclusionFor multiple incisional hernias, it is necessary to consider appropriate repair methods for each site.
