Summary

Effective postoperative pain management is essential for enhanced recovery after laparoscopic colorectal surgery. This randomized, controlled, double-blind trial will compare conventional postoperative analgesia (intravenous medications plus surgical wound infiltration) with a locoregional strategy combining a peripheral autonomic block (inferior mesenteric and superior hypogastric plexuses) and a transversus abdominis plane (TAP) block. We hypothesize that the combined strategy (BAPTAP) reduces pain intensity and opioid consumption in the first 48 hours after Left-Sided Colorectal Resection.

Interventions

PROCEDURE

Minimally Invasive Left-Sided Colorectal Resection

Elective laparoscopic anterior/rectosigmoid resection or sigmoid colectomy per institutional standards; not randomized.

PROCEDURE

BAPTAP (Peripheral Autonomic Blockade + TAP Block)

General anesthesia combined with peripheral autonomic plexus blockade (superior hypogastric and inferior mesenteric plexuses) using 0.2% ropivacaine, 8 mL per site; performed laparoscopically prior to dissection, in association with bilateral ultrasound-guided TAP block with 0.33% ropivacaine, 30 mL per side.

PROCEDURE

Trocar/Incision Infiltration

General anesthesia with trocar/incision infiltration using 0.33% ropivacaine, up to a total volume of 60 mL.
