Background: Pain associated with laparoscopic cholecystectomy is most severe during the first 24 h and the port sites are the most painful. Recent multimodal approaches target incisional pain instead of visceral pain which has led to the emergence of abdominal fascial plane blocks. This study embraces a novel combination of two independently effective fascial plane blocks, namely rectus sheath block and subcostal transversus abdominis plane (TAP) block to alleviate postoperative pain. Study Objective: The aim is to evaluate the effectiveness of the combination of rectus sheath block and subcostal TAP block, to compare its efficacy with that of subcostal TAP block alone and with conventional port site infiltration (PSI) in alleviating postoperative pain in patients undergoing laparoscopic cholecystectomy. Methodology: This prospective, randomized control, pilot study included 61 patients scheduled for elective laparoscopic cholecystectomy and distributed among three groups, namely Group 1: Combined subcostal TAP block with rectus sheath block (n = 20); Group 2: Oblique subcostal TAP block alone (n = 21); and Group 3: PSI group as an active control (n = 20). Results: Combined group had significantly lower pain scores, higher satisfaction scores, and reduced rescue analgesia both in early and late postoperative periods than the conventional PSI group. Conclusion: Ultrasound-guided combined fascial plane blocks is a novel intervention in pain management of patients undergoing laparoscopic cholecystectomy and should become the standard of care.
