Novel laparoscopic methods for inguinal hernia post pelvic fracture: A case report

INTRODUCTION: Pelvic fractures can occur in minor injuries, such as falls, in the elderly. Extensive adhesion of preperitoneal space is common after pelvic fracture surgery; hence, surgical interventions for inguinal hernia may be challenging. We treated a case of inguinal hernia after pelvic fracture surgery, using novel laparoscopic methods: iliopubic tract repair (IPTR) and modified intraperitoneal onlay mesh (mIPOM) approach. PRESENTATION OF CASE: This is the case of an elderly male with pelvic fracture. Open reduction and internal fixation were performed. Eighteen months after the procedure, a right inguinal bulge appeared, swelling increased, and he opted for surgery. We chose laparoscopic surgery to determine the status of the hernia and anatomy around the pelvis. He was diagnosed with an indirect inguinal hernia, and the inner inguinal ring was widely open. We chose the mIPOM approach and IPTR. He was discharged on day 3 post-operation. He developed a seroma after surgery, which disappeared after a month. Six months post-operation, no recurrence or neurologic pain observed. DISCUSSION: The transabdominal preperitoneal approach (TAPP) was initiated at first; however, the adhesion inside the inferior epigastric vessels was very strong, challenging to break into the preperitoneal space. We switched to the mIPOM method because the peritoneum was fragile and difficult to suture. Additionally, the internal ring was widely opened; hence, we proceeded with IPTR on confirmation that no tension on the abdominal wall was applied. CONCLUSIONS: Laparoscopic surgery is useful in flexibility of surgical options, such as TAPP, IPTR, IPOM, in addition to hybrid conversion.
