Comparison of modified tumescent and conventional laparoscopic transabdominal preperitoneal inguinal hernia repair: a retrospective clinical study.

Abstract

<h4>Objective</h4>Laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair poses certain challenges to less experienced surgeons. This study was performed to compare the clinical outcomes of modified tumescent laparoscopic TAPP (MT-TAPP) inguinal hernia repair versus conventional laparoscopic TAPP (CL-TAPP) inguinal hernia repair.<h4>Methods</h4>We retrospectively analyzed the perioperative data of patients with inguinal hernias who underwent either MT-TAPP repair (n = 57) or CL-TAPP repair (n = 54) at the General Surgery Department of Nanjing Yimin Hospital from November 2019 to June 2023.<h4>Results</h4>The durations of the total operation and the preperitoneal space dissection were shorter in the MT-TAPP than CL-TAPP group. The estimated blood loss volume was lower in the MT-TAPP than CL-TAPP group. The visual analogue scale scores recorded at the 12- and 24-hour postoperative time points showed significantly greater reductions in the MT-TAPP than CL-TAPP group.<h4>Conclusions</h4>Using liquid injection and gauze dissection is both safe and practical. This technique results in a shortened total operation time, less time spent on preperitoneal space dissection, decreased estimated blood loss, and less severe postoperative pain.
