Asymptomatic colonic intussusception in ulcerative colitis: a case report

Intussusception in adults is, especially with ulcerative colitis (UC), rare and only described in a few cases. Most adult patients with intussusception develop abdominal pain or other symptoms of bowel obstruction. This case describes an 18-year-old male with UC who treated with 5-aminosalycilicacid and underwent annual screening colonoscopies. Two attempts revealed that it was impossible to achieve total surveillance through the colonoscopy because multiple polyps were preventing the colonoscope from traversing the entire colon. Therefore, CT scan was performed and colonic intussusception was discovered incidentally, and the patient underwent elective laparoscopic total colectomy. To the best of our knowledge, this is the first reported case of asymptomatic intussusception in the adult patient with UC. When total surveillance colonoscopy fails to yield results, a CT may be advisable to pick up such an asymptomatic intussusception.
