Purpose:
The current study summarized the clinical course and treatment outcomes of intestinal cancer in CD seen in our department and explored the steps to take in the future.
Methods:
Subjects were patients who had been diagnosed with CD at our hospital and who underwent surgery in our department from 1985 to 2020.
Results:
Thirty-one patients had CD and intestinal cancer, including 6 with cancer of the small intestine and 25 with cancer of the large intestine. In all six patients with cancer of the small intestine, the site where cancer or a tumor developed was at or near the site of the anastomosis made at a previous surgery. Of the 25 patients with cancer of the large intestine, 22 developed cancer in the rectum or anal region.
Conclusion:
Many of the patients with cancer of the small intestine had previously undergone surgery, and the cancer developed at or near the site of the anastomosis. In patients who have previously undergone resection of the small intestine, the small intestine needs to be examined regularly. Cancer of the large intestine often developed in the rectum or anal region of our patients, so a detailed examination of the same site needs to be performed.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
