Local wound infiltration plus transversus abdominis plane (TAP) block versus local wound infiltration in laparoscopic colorectal surgery and ERAS program

Abstract

Few data are available on TAP block in laparoscopic colorectal surgery and ERAS program. The aim of this prospective study was to evaluate local wound infiltration plus TAP block compared to local wound infiltration in the management of postoperative pain, nausea and vomiting, ileus and use of opioids in the context of laparoscopic colorectal surgery and ERAS program. From March 2014 to March 2015, 48 patients were treated by laparoscopic resection and ERAS program for colorectal cancer and diverticular disease at the Division of General and Hepatobiliary Surgery, University of Verona Hospital Trust. Among these, 24 patients received local wound infiltration plus TAP block (TAP block group) and 24 patients received local wound infiltration (control group). No differences were observed in baseline patient characteristics, clinical variables and surgical procedures between the two groups. Local wound infiltration plus TAP block allowed to achieve pain control despite a reduced use of opioid analgesics (P=0.009). The adoption of TAP block resulted beneficial on the prevention of postoperative nausea (P=0.002) and improvement of essential outcomes of ERAS program as recovery of bowel function (P=0.005), urinary catheter removal (P=0.003) and capability to tolerate oral diet (P=0.027). TAP block plus local wound infiltration in the setting of laparoscopic colorectal surgery and ERAS program guarantees a reduced use of opioid analgesics and good pain control allowing the improvement of essential items of enhanced recovery pathways.
