Core Tip
Core Tip: This retrospective study compared the analgesic efficacy of erector spinae plane block (ESPB) and transversus abdominis plane block in patients undergoing laparoscopic appendectomy, with a specific focus on differentiating visceral and somatic pain. The results showed that ESPB provided significantly better control of early postoperative visceral pain within the first 12 hours compared with transversus abdominis plane block, while both techniques demonstrated similar effectiveness for somatic pain. Patients receiving ESPB also required less rescue analgesia and reported higher satisfaction with postoperative pain management. These findings suggest that ESPB may be a preferable regional analgesic technique for laparoscopic appendectomy when visceral pain is the predominant postoperative component.
