Laparoscopic intraperitoneal versus enhanced-view totally extraperitoneal retromuscular mesh repair for ventral hernia: a retrospective cohort study

Abstract

BACKGROUND: Laparoscopic enhanced-view totally extraperitoneal retromuscular repair (eTEP-RM) was recently introduced as a new technique for ventral hernia repair. The aim of the current study was to examine the outcomes of laparoscopic eTEP-RM compared with laparoscopic IPOM for patients with primary ventral and incisional hernia.

METHODS: This was a retrospective cohort study of patients undergoing laparoscopic ventral hernia repair at a single University Hospital from June 2017 to November 2020. Medical charts of all patients subjected to IPOM and eTEP-RM were evaluated to identify patient- and procedure related variables, as well as postoperative 30-day outcomes.

RESULTS: A total of 72 patients were included in the study, 43 and 29 of whom underwent IPOM and eTEP-RM repair, respectively. Patient demographics showed no differences in terms of gender, age, smoking and comorbidity. The median age was 57 years and body mass index 30.5 kg/m2. The rate of patients with incisional hernia was higher in the IPOM group (39.5% vs. 20.7%, p = 0.154). There was no difference in horizontal and vertical hernia size defect. The duration of surgery was significantly shorter for IPOM (mean 82.4 vs. 103.4 min, p = 0.010), whereas the length of stay was significantly longer after IPOM (median 1 days vs. 0 days (p < 0.001). The rate of patients requiring postoperative transversus abdominis plane (TAP) block or epidural analgesia was significantly higher after IPOM (33% vs. 0%, p = 0.002). A subgroup analysis on patients undergoing primary ventral hernia showed similar results.

CONCLUSION: The study found laparoscopic eTEP-RM safe and effective compared to traditional laparoscopic IPOM. The patients undergoing eTEP-RM had significantly reduced need for additional analgesic treatment and length of stay.
