Laparoscopic versus ultrasound-guided subcostal transversus abdominis plane block in sleeve gastrectomy: A randomised comparison of analgesic effectiveness and procedural feasibility

Both USG-subcostal and L-subcostal TAP blocks provide effective early post-operative analgesia in LSG. While USG-subcostal TAP had a longer duration of effect, L-subcostal TAP offers practical advantages including ease of use, shorter application time and no requirement for specialised equipment. In settings with limited access to ultrasound or trained personnel, L-subcostal TAP can be considered a safe and effective alternative within multimodal analgesia strategies.
