Sigmoid stenosis caused by diverticulitis vs. carcinoma: usefulness of sonographic features for their differentiation in the emergency setting.
Stefánsson T, Bergman A, Ekbom A, Nyman R, Påhlman L. Olsson R, Adnerhill I, Björkdahl P, Ekberg O, Fork FT. Acta Radiol. Sixty percent of significant colonic obstructions are due to primary colonic malignancies, and, of these, the majority of obstructions occur in the sigmoid region [3] . Nine malignant strictures were called benign, three at both assessments. [CT of acute left-sided colonic diverticulitis and its differential diagnoses]. Nine malignant strictures were called benign, three at both assessments. When consensus existed, the positive predictive value for malignant strictures was 96% at both assessments (sensitivity, 63% and 66%).

No significant difference existed between the areas under the receiver operating characteristic curves for the two assessments with any observer. Purpose: Surgery has traditionally been the mainstay of treatment but is associated with high complication rates and morbidity.
Conclusion: The etiology of strictures is broad and generally categorized as benign, malignant, or pseudostrictures. [Biliary ileus of the sigmoid: its echographic diagnosis. Please enable it to take advantage of the complete set of features! NLM

Refractory strictures are more commonly due to corrosive injury or surgical anastomoses than a peptic etiology.
