Clinical and radiographic features of bowel stricture with stenosis – all of the following:
(1) symptoms of bowel obstruction (abdominal pain, vomiting, abdominal distention, etc)
(2) focus of persistent, localized luminal narrowing
(3) dilatation of the bowel proximal to the area of luminal narrowing
The area of luminal narrowing may be evaluated by:
(1) endoscopy
(2) small bowel enema (SBE) with enteroclysis
(3) double contrast barium enema for evaluation of the colon
(4) CT scan
(5) MRI-enteroclysis
(6) contrast enhanced Doppler ultrasound
The presence of mucosal ulceration in the involved segment correlates with disease activity.
Differential diagnosis:
(1) functional spasm
