Feasibility of laparoscopic indirect inguinal hernia repair with lateral umbilical fold covering internal inguinal ring combined with patch repair.

Abstract

<h4>Introduction</h4>For an indirect inguinal hernia (IIH), it is a challenge to repair the internal inguinal ring (IIR) with self-tissue reconstruction in laparoscopic repair.<h4>Aim</h4>To evaluate the efficacy and safety of covering the IIR with the lateral umbilical fold (LUF) combined with patch repair in laparoscopic indirect inguinal hernia repair.<h4>Material and methods</h4>Patients with IIH treated by trans-abdominal preperitoneal (TAPP) hernia repair at the Department of General Surgery, Shanghai Public Health Clinical Centre between September 2019 and March 2021 were retrospectively analyzed. In group I (n = 57) the LUF was overturned and sutured to cover the IIR under a laparoscope and subsequently repaired with a patch. In group II (n = 62), the IIR was not covered by the LUF but only repaired with a self-gripping mesh.<h4>Results</h4>We noted a longer suture time in group I than in group II. Although the LUF was covered after suturing, no significant difference in postoperative pain was observed between the two groups. However, significant differences in surgery time and hospitalization cost (p < 0.05) were found. One case of recurrence was observed in group II.<h4>Conclusions</h4>The LUF can be used in IIH to cover the IIR and is a feasible approach. The LUF covering the IIR has no significant difference in pain.
