ABSTRACT
Introduction: The aim of this study was to compare the peri-operative outcomes, especially intraoperative surgeon workload and early post-operative pain, following midline ventral hernia repair by laparoscopic enhanced-view totally extraperitoneal (eTEP) approach and laparoscopic intraperitoneal onlay mesh plus (IPOM plus) approach. Patients and Methods: This single-centre randomised control trial study was conducted from January 2020 to June 2022. A total of 60 adult patients undergoing elective ventral hernia surgery with small- and medium-sized midline defects were included. Intraoperative surgeon workload and early post-operative pain were systematically recorded and analysed for each procedure. Results: Out of 30 patients assigned to each group, 29 patients underwent eTEP mesh repair and 27 patients underwent successful IPOM plus repair. The intraoperative surgeon's workload, especially mental demand, physical demand, task complexity and degree of difficulty as reported and felt by the operating surgeon, was significantly higher in the eTEP mesh repair group compared to IPOM plus group (P < 0.001) with comparable operating room distractions (P = 0.039). The mean overall post-operative pain score on post-operative day 1 was slightly less in eTEP mesh repair (4.28 ± 1.12) group compared to IPOM plus group (4.93 ± 1.17), which was statistically insignificant (P = 0.042). The eTEP group had significantly longer operative time and length of hospital stay compared to the IPOM plus group. Conclusion: Our study revealed significantly longer operative time, higher surgical workload and increased length of hospital stay in the eTEP group with comparable early post-operative pain in both groups, thus making eTEP mesh repair a more difficult and challenging procedure.
