Laparoscopic cholecystectomy causes moderate to severe pain despite its minimally invasive nature. This study was performed to compare the efficacy of the bilateral erector spinae plane block (ESPB) and the subcostal transversus abdominis plane block (STAPB) under ultrasound guidance. ⋯ Bilateral ultrasound-guided ESPB provides superior analgesia after laparoscopic cholecystectomy surgery compared to STAPB and further reduces unaided walking time and hospital stay.
