Colonoscopic Intubation of the Appendix Through a Patulous Appendiceal Orifice in Ulcerative Colitis

Year: 2026

Type: article

Abstract: A 37-year-old woman with a 17-year history of left-sided ulcerative colitis was in remission on 5-aminosalicylic acid monotherapy after treatment with corticosteroids and azathioprine.Owing to previous insertion difficulty, she underwent surveillance colonoscopy using an ultrathin colonoscope (PCF-PQ260 L; Olympus, Tokyo, Japan; 9.2 mm in diameter).Although remission was confirmed throughout the colorectum, the scope was inadvertently advanced through a dilated appendiceal orifice into the appendiceal lumen (Picture A, B).Computed tomography revealed no appendiceal tumor (Picture C).A retrospective review revealed that periappendiceal inflammation had been present seven years earlier
