Local Wound Infiltration Plus TAP Block Versus Local Wound Infiltration Only

Colorectal Disorders Clinical Trial

Official title: Comparison of Analgesic Efficacy of Local Wound Infiltration Plus Transversus Abdominis Plane Block and Local Wound Infiltration Only After Laparoscopic Colorectal Resection: a Randomized, Double-blind, Non-inferiority Trial

Status Completed

Clinical Trial Summary

The TAP block is typically performed either with ultrasound guidance (TAP-US) or laparoscopic visualization (TAP-LAP): comparison between these two technics showed no differences in pain control and use of opioid analgesics.

The investigators hypothesize that WI is non-inferior to WI + TAP-block with respect to postoperative pain.

Clinical Trial Description

In colorectal surgery, laparoscopy and enhanced recovery after surgery (ERAS) programs have significantly improved the short-term outcomes (1). Although the laparoscopic approach reduces pain and recovery time, post-operative pain, nausea and vomiting still represent an issue. In order to reduce opioid related side effects, such as postoperative nausea and vomiting (PONV), constipation and prolonged post-operative ileus, non-opioid based multimodal analgesia have been recently introduced. Although epidural analgesia has gained good success, it does not seem to offer any additional clinical benefits to patients undergoing laparoscopic colorectal surgery compared to alternative analgesic technique within an ERAS program. Both local wound infiltration (WI) and TAP block are common techniques in multimodal postoperative pain treatment, and their association allows to achieve pain control despite a reduced use of opioid analgesics. Furthermore, in a recent single-blind prospective study TAP block resulted superior to wound infiltration alone. The TAP block is typically performed either with ultrasound guidance (TAP-US) or laparoscopic visualization (TAP-LAP): comparison between these two technics showed no differences in pain control and use of opioid analgesics.

The aim of this study is to compare WI + TAP-LAP versus WI alone. The investigators hypothesize that WI is non-inferior to WI + TAP-block with respect to postoperative pain. ;
