Although Transversus abdominis plane block combined with rectus sheath block(TAP+RSB） can effectively alleviate this pain, it still has many limitations. The external oblique intercostal plane block (EOIB) is a novel nerve block technique that may provide well postoperative analgesia for upper abdominal surgery. Therefore, this study employs a non-inferiority randomized controlled trial design to verify that the analgesic effect of EOIB is not inferior to that of ESPB, thereby offering more options for regional analgesia strategies in laparoscopic radical gastrectomy.",[73],"Postoperative Pain","2026-03-22",{"date":76,"type":77},"2026-03-27","ACTUAL",{"date":79,"type":77},"2026-03-20",{"date":81,"type":67},"2026-11-03",{"name":5,"class":6},1]
