Zig Maneuver in Total Extraperitoneal Inguinal Hernia Repair

Abstract

Background: The difficulties in the hernia sac dissection in repairing large inguinal hernias with the endoscopic total extraperitoneal (TEP) technique prolong the operation and increase the risk of injury. This study investigates the effectiveness of the Zig maneuver (ligation of the hernia sac at the deep inguinal ring) in TEP in male patients with L3 inguinal hernia by European Hernia Society classification. Materials and Methods: A total of 224 male patients with L3 inguinal hernia who underwent laparoscopic TEP surgery in 2018 and 2019 were retrospectively screened and included in the study. The patients were divided into 2 groups as Zig group (n=99) and the non-Zig group (n=125), depending on whether the Zig maneuver was performed during TEP application. Results: The mean patient age was 45.49 for the non-Zig group and 47.12 for the Zig group. The median operative time was 50 minutes in the non-Zig group and 43 minutes in the Zig group (P<0.005). The median value of the postoperative first 24 hours pain score was 3 in the non-Zig group and 2 in the Zig group (P=0.033). Scrotal edema was 7.2% in the non-Zig group and 1% in the Zig group (P=0.023). According to logistic regression analysis, the Zig maneuver reduced the probability of scrotal edema by 87% in almost the entire population (odds ratio=0.130, 95% confidence interval: 0.016-1.047). There was no statistically significant difference between the groups in terms of early and late recurrence. Conclusions: Zig maneuver shortened the operative time and significantly reduced the feeling of pain in the first 24 hours postoperatively in male patients with indirect L3 hernia who underwent endoscopic TEP. It also significantly reduced the likelihood of scrotal edema in almost the entire population. As a result, the Zig maneuver is an effective method that could be applied during endoscopic TEP.

Routine closed-suction drainage reduces seromas following totally extraperitoneal (TEP) inguinal hernia repair: A meta-analysis

“…A further approach is the excision and/or ligation of the hernia sac. [ 18 ] Insertion of drainage tubes to avoid seromas has been common practice for decades. Conversely just 4 studies that match our search criteria exist that control the hypothesis in TEP hernia repair.…”
