Transcolonic endoscopic appendectomy via snare-through-line resection for stump appendicitis

A 16-year-old girl was admitted due to recurrent abdominal pain 10 months after laparoscopic appendectomy. Physical examination showed tenderness at the McBurney point. Computed tomography revealed a distended appendiceal stump with peristump inflammation and dense suture material at the ligated end. After comprehensive preoperative assessment, transcolonic endoscopic appendectomy was chosen.
