Laparoscopic transabdominal preperitoneal approach for giant inguinal hernias

Summary Background Many surgical techniques have been developed to treat inguinal hernia. In recent years, the laparoscopic transabdominal preperitoneal (TAPP) approach has been widely performed to repair inguinal hernia. Giant inguinal hernia (GIH) is an extremely rare disease that is a challenge for general surgeons. GIH appears when patients neglect the treatment for many years and it is defined as an inguinal hernia that extends below the midpoint of inner thigh in standing position. According to previous publications, the Lichtenstein tension-free hernioplasty is recommended to repair GIH. In this article, we describe consecutive four cases of GIH repaired via the TAPP approach. Methods From April 2015 to March 2017, 200 patients underwent hernioplasty against inguinal hernia at our hospital. Inguinal hernias were treated via the TAPP approach in principle. We performed hernioplasty via the TAPP approach in all 4 patients (2%) who met the definition of Type 1 GIH. Demographic information, maximum diameter of hernia sac, hernia orifice size, and surgical data were obtained. Results The mean operative time was 135 min. No intraoperative complications were encountered. All patients could walk from postoperative day 1 and were discharged home early, but they all had scrotal seromas. Three patients did not need puncture or drainage, but one of them required puncture. All seromas disappeared within 6 months. There was no recurrence in the 8- to 24-month follow-up. Conclusion The TAPP approach is a feasible, safe therapeutic option that may reduce wound size and pain following surgical treatment of Type 1 GIH.
