269.Strictures in Crohn's disease（4）

每天朗读一段医学影像学英语文章

High-grade small bowel obstruction due to Crohn's disease is rare.  However, surgery may be necessary in patients with repeated partial obstructions and fibrotic, non-distensible strictures or in patients in whom carcinoma is suspected. Resective surgery is often followed by disease recurrence and renewed stricture formation or adhesions causing renewed obstruction. Therefore, whenever possible, stricturoplasty should replace resective surgery. The small bowel enema can demonstrate an obstruction caused by stenotic Crohn's disease.
