Comparative Efficacy of ESPB and EOPB for Postoperative Analgesia in Laparoscopic Cholecystectomy: A Randomized Controlled Trial (External Oblique Intercostal Plan Block (EOPB) and Erector Spina Plan Block (ESPB) )

This randomized controlled clinical trial investigates the comparative efficacy of two novel regional anesthesia techniques - the Erector Spinae Plane Block (ESPB) and the External Oblique Intercostal Plane Block (EOPB) - for postoperative analgesia in patients undergoing elective laparoscopic cholecystectomy under general anesthesia. A total of 90 patients aged 18-65 years, with ASA physical status I or II, were randomly assigned to one of three groups: ESPB, EOPB, or control. Blocks were performed under ultrasound guidance prior to surgical incision. Pain intensity was evaluated using the Visual Analog Scale (VAS), and rescue analgesic consumption was recorded over the first 24 hours postoperatively. The study aims to determine whether ESPB or EOPB offers superior pain control and reduced opioid consumption, and to assess patient satisfaction and safety. The results will inform multimodal analgesia strategies for upper abdominal laparoscopic surgery.
