Brief summary
This prospective randomized controlled trial aims to compare the analgesic efficacy and effects on diaphragmatic function of bilateral erector spinae plane (ESP) block and bilateral rhomboid intercostal-subserratus plane (RISS) block in patients undergoing elective laparoscopic cholecystectomy. Postoperative pain scores, opioid consumption, diaphragmatic excursion, pulmonary function, and recovery outcomes will be evaluated.
Detailed description
Postoperative pain after laparoscopic cholecystectomy may impair respiratory function and delay recovery. Fascial plane blocks have emerged as effective opioid-sparing analgesic techniques. The erector spinae plane (ESP) block and rhomboid intercostal-subserratus plane (RISS) block are ultrasound-guided regional anesthesia techniques that may provide effective postoperative analgesia while preserving respiratory mechanics. This prospective randomized controlled study will compare bilateral ESP block and bilateral RISS block in adult patients undergoing elective laparoscopic cholecystectomy under general anesthesia. The primary objective is to compare postoperative analgesic efficacy and diaphragmatic function. Secondary outcomes include postoperative opioid consumption, pain scores at rest and during movement, pulmonary function parameters, rescue analgesic requirements, and adverse events.
Interventions
Bilateral ultrasound-guided erector spinae plane block performed before laparoscopic cholecystectomy for postoperative analgesia.
Bilateral ultrasound-guided rhomboid intercostal-subserratus plane block performed before laparoscopic cholecystectomy for postoperative analgesia.

Study design
Masking description
Participants and outcome assessors will be blinded to group allocation. Regional blocks will be performed by an anesthesiologist not involved in postoperative assessments.
Intervention model description
Participants will be randomized in a 1:1 ratio to receive either bilateral erector spinae plane block (ESP) or bilateral rhomboid intercostal-subserratus plane block (RISS) before elective laparoscopic cholecystectomy. Outcomes will be compared between two parallel groups.
