الإجابة: A. Crohn's disease can affect upper and lower gastrointestinal tract
This patient has duodenal plus colonic involvement, with the rectum spared (disease runs transverse to sigmoid). That pattern fits Crohn's disease, which can affect any segment of the GI tract from mouth to anus.
- Ulcerative colitis is limited to the colon and rectum. It does not involve the duodenum, even with NSAID use.
- Neither UC nor Crohn's is diagnosed on gross colonoscopic appearance alone; biopsy and histology are needed.
