Peripheral Autonomic Block (BAP) Plus Transversus Abdominis Plane Block (TAP) for Postoperative Analgesia After Minimally Invasive Left-Sided Colorectal Resection (BAPTAP)

This study is testing a combination of two nerve block techniques — a peripheral autonomic block (BAP) and a transversus abdominis plane (TAP) block — as a way to reduce pain after minimally invasive (laparoscopic) surgery on the left side of the colon or rectum. These nerve blocks are injections of local anesthetic that temporarily numb specific areas to reduce post-surgical pain and the need for opioids. **You may be eligible if...** - You are scheduled for a planned (non-emergency) laparoscopic left-sided colorectal resection surgery - You are in generally good health (ASA physical status I or II) - You can understand the study and sign informed consent **You may NOT be eligible if...** - You have a known allergy to local anesthetic medications - You have a blood clotting disorder - You are pregnant - You are unable to understand or consent to the study - You are on long-term opioid therapy for chronic pain - Your BMI is greater than 35 kg/m² Talk to your doctor to see if this trial is right for you.
