The Effect of Unilateral Subcostal Transversus Abdominis Plane Block Applied as Single or Multiple Injections on Pain in Laparoscopic Cholecystectomy

Background

Effective postoperative pain management in cases of laparoscopic cholecystectomy is essential for recovery and patient satisfaction. The subcostal transversus abdominis plane (TAP) block is a regional analgesic technique used for upper-abdominal pain. While the single-injection TAP has shown benefits in reducing perioperative opioid consumption, the comparative efficacy of the multi-injection version of this block remains insufficiently studied.
