The laparoscopic approach has become the gold standard for many abdominal surgical procedures, including cholecystectomy. Compared to laparotomy, laparoscopy allows smaller incisions, reduces perioperative stress response, reduces postoperative pain, and results in shorter recovery time.

However, anaesthesia concerns in patients undergoing laparoscopic surgery are different from patients undergoing open abdominal surgery.

The aim of this study is to investigate the effect of the external oblique intercostal block, which is a new block, on postoperative pain score and opioid consumption.

• Laparoscopic cholecystectomy

Exclusion Criteria:
