Background: Although rare, duodenal lesions have been reported in association with ulcerative colitis (UC); however, there have been very few reports on small bowel lesions, and many aspects of their pathology and frequency remain unknown. This study determined whether small bowel lesions are present in UC by using wireless capsule endoscopy (WCE). Patients and Methods: WCE was performed on 20 patients with active UC and 10 who had undergone proctocolectomy. Results: Small bowel lesions (e.g. edema or ulcers) were observed in 11 of the 30 patients (36.6%): in eight (40%) of the 20 patients with active UC and in three (33.3%) of the 10 post‐proctocolectomy patients. Ulcers that extended over a long segment or whole tertile of the small bowel were observed in five patients, and the disease type was extensive colitis in three of these and pouchitis in the other two. Age at onset was significantly lower in the 20 active UC patients that had small bowel lesions. Conclusion: WCE revealed the presence of ulcers that extended over a long segment or a whole tertile in the small bowel in active extensive colitis and pouchitis. In future, it will be necessary to assess the clinical significance of small bowel lesions in UC in detail.
