Liquid-injection for preperitoneal dissection of transabdominal preperitoneal (TAPP) inguial hernia repair

Abstract

Our preliminary experience suggests that liquid-injection to assist preperitoneal dissection during TAPP inguinal hernia repair appears to be safe and feasible. This novel method facilitates the dissection of spermatic cord structures, and can be used to minimize trauma to surrounding structures, especially when performed by trainees with limited operative experience.

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

“…The liquidinjected area was successfully dissected using gauze. Mizota et al 27 were the first to describe the use of preperitoneal tumescent local anesthesia in 2015. They reported that after trocar placement, 60 mL of 0.3% lidocaine with 1:300,000 dilution of epinephrine was percutaneously injected using a blunt needle.…”

“…They reported that after trocar placement, 60 mL of 0.3% lidocaine with 1:300,000 dilution of epinephrine was percutaneously injected using a blunt needle. 27 We avoid percutaneous puncture, thereby reducing the risk of puncture-related infection and minimizing postoperative pain. Tokumura et al 28 introduced the concept of tumescent TAPP repair.…”
