Background: This case report describes the use of an ultrasound-guided external oblique intercostal (EOI) plane block for postoperative analgesia in a patient undergoing elective laparoscopic cholecystectomy. A 45-year-old male (ASA I) with symptomatic gallstones underwent uneventful laparoscopic cholecystectomy under general anesthesia. In addition to standard analgesics (paracetamol), a right-sided EOI block was performed at the end of surgery using 20 mL of 0.25% bupivacaine (injected at the level of the 6th rib) to target the lateral and anterior cutaneous branches of T6/7–T10/11.
Results: Postoperatively, the patient reported only mild pain (NRS ≤2) at rest and with movement over 24 h, required minimal rescue analgesia (single dose of 100mg iv tramadol), and had stable vital signs. This favorable outcome aligns with recent evidence that EOI plane block reduce postoperative pain and opioid requirements.
Conclusion: This case highlights that an ultrasound-guided EOI block can be a simple, safe, and effective component of multimodal analgesia for laparoscopic upper abdominal surgery.
