Abstract
OBJECTIVE: The management of the hernia sac is the core step of laparoscopic indirect inguinal hernioplasty. In this study, a randomized controlled trial was conducted to evaluate the clinical effect of laparoscopic total extraperitoneal inguinal herniorrhaphy (TEP) with hernia sac transection and complete sac reduction. METHOD: From May 2017 to May 2018, 70 patients aged 18-75 with primary indirect inguinal hernia in our hospital were randomly divided into a transected sac group (TS) and a completely reduced sac group (RS). The primary outcomes compared between the two groups were the hernia sac treatment time, operation time, and the incidence of seroma formation after operation. Secondary outcomes included acute pain, chronic pain (pain which lasted for at least 3 months), hospital stay, recurrence rate, and other complications. RESULT: There were no significant differences in baseline demographic characteristics including age, sex, hernia type, size of hernia defect, and follow-up time between the two groups. The times required for hernia sac separation and operation in the TS group were significantly shorter than in the control group (6.1 ± 2.3 vs. 25 ± 5.8 min for hernia sac separation, p < 0.01; and 35.10 ± 3.50 vs. 54.40 ± 4.20 min for operation, p < 0.01). There was no significant difference in hospitalization time, incidence of acute pain, seroma formation, or urinary retention between the two groups. During the 12-month follow-up period, chronic pain, early recurrence, and other complications were not found in either group. CONCLUSION: Both the hernia sac transection technique and the complete sac reduction technique are safe and reliable. The hernia sac transection technique is a simple and effective hernia sac treatment method. It reduces the operation time and does not increase seroma or acute or chronic pain. It is valuable and likely to be popularly applied.
