Postoperative pain after laparoscopic cholecystectomy remains clinically relevant. This double-blinded randomized controlled trial compares the analgesic efficacy of landmark-guided Erector Spinae Plane Block (ESPB) and subcostal transversus abdominis plane (STAP) block in 60 adult patients. Postoperative pain will be evaluated using the Visual Analogue Scale at multiple time points, along with rescue analgesic requirements and time to first analgesic request, to assess the effectiveness of these techniques in resource-limited settings.
