Core Tip

Core tip: This comparative study validates the effectiveness of perioperative administration of oral selective cyclooxygenase-2 (COX-2) inhibitors as a part of multimodal analgesia in an enhanced recovery after surgery protocol to significantly reduce opioid requirement (but not pain score) after open colorectal surgery. Our findings also indicate that opioid-sparing effect of selective COX-2 inhibitor has some important clinical benefits including quicker gastrointestinal recovery and shorter hospitalization.
