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.
