Abstract
Conclusions Spastic diverticulosis is defined and differentiated from diverticulitis. Persistence of the filling defect and constancy of its location are not essential for the diagnosis of a small polypoid lesion in an area of spastic diverticulosis. A single positive finding of an intraluminal defect in spastic diverticulosis is more significant than numerous negative findings. Discovery of an intraluminal defect in an area of spastic diverticulosis demands re-examination after antispasmodic therapy. Differentiation between a polypoid lesion in an area of diverticulosis and the intrinsic features of diverticulitis are discussed. Circumferential visualization of the colon is essential to differentiate a polyp from a diverticulum. Fecal defects in an area of spastic diverticulosis are comparatively uncommon, so that such a defect should be considered a polypoid lesion until its presence is disproved.
