Abstract

<p>Purpose: A prospective study was performed to examine the efficacy of infiltration anesthesia (IA) on the inguinal pain after a transabdominal preperitoneal repair (TAPP) for primary unilateral adult inguinal hernias.</p><p>Methods: One hundred four patients were randomly divided into two groups, 52 cases who received IA (0.75% ropivacaine) (IA group), and another 52 cases without IA (Non-IA group) during the period from August 2018 to April 2019. In the IA group, we injected 20 ml of 0.75% ropivacaine into the affected inguinal floor before the peritoneal incision. The degree of pain was evaluated with visual analogue scale (VAS) scores for the affected inguinal lesion in postoperative days (PODs) 1 and 14 and by the quantity of postoperative analgesics required.</p><p>Results: There were no significant differences between the two groups for all compared items: the VAS scores for the groin pain at PODs 1 and 14, the amount of postoperative analgesics used, operation time, bleeding volume, postoperative hospital stay, VAS scores of the port site pain, VAS scores of patient satisfaction or complications.</p><p>Conclusion: IA in the inguinal floor was not effective to reduce the inguinal pain in TAPPs.</p>
