External Oblique Intercostal Block in Laparoscopic Cholecystectomy

Adequate pain relief in the postoperative period is a crucial determinant of patient comfort, early mobilization, and overall recovery after laparoscopic cholecystectomy. Effective analgesia not only improves patient satisfaction but also reduces postoperative complications, facilitates respiratory function, and shortens hospital stay. Conversely, insufficient pain control may lead to undesirable outcomes such as delayed mobilization, nausea, vomiting, increased opioid requirements, and prolonged recovery. Regional anesthesia techniques, particularly abdominal wall and fascial plane blocks, have gained increasing attention as part of multimodal analgesia strategies aimed at reducing opioid consumption and minimizing related adverse effects. Among these, the external oblique intercostal block (EOIB) has recently been described as a novel regional technique that may provide effective postoperative pain relief. In clinical practice, port-site infiltration with local anesthetics is a commonly used and simple technique for providing postoperative analgesia in laparoscopic procedures, although its effectiveness may be limited. The present study was designed to compare the effectiveness of the external oblique intercostal block with port-site infiltration in patients undergoing laparoscopic cholecystectomy, with a focus on postoperative pain scores and opioid consumption during the first 24 hours after surgery.
