Brief 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.


Condition or disease Intervention/treatment Phase
Colorectal Disorders Procedure: Wound infiltration plus TAP Procedure: Wound infiltration Not Applicable

Detailed 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.

Arm Intervention/treatment
Experimental: Wound infiltration plus TAP
Wound infiltration placed by surgeon + TAP-LAP placed laparoscopically guided by surgeon
Procedure: Wound infiltration plus TAP
  1. TAP block: At the beginning of the main surgical procedure the surgeon will perform a TAP with ropivacaine infiltration, bilaterally in the anterior axillary line, between the costal margin and iliac crest in the intermuscular plane between the internal oblique and transversus abdominis muscles, the anesthesiologist under ultrasound guidance, the surgeon under laparoscopic guidance (two "pops" technique).
  2. Wound infiltration : Wound infiltration of ropivacaine will be performed by the surgeon before skin incision.
Other Name: ropivacaine

Active Comparator: Wound infiltration
Wound infiltration placed by surgeon
Procedure: Wound infiltration
Wound infiltration of ropivacaine will be performed by the surgeon before skin incision.
Other Name: ropivacaine
