title: Sigmoid volvulus in two patients with progressive systemic sclerosis.
abstract: Sigmoid volvulus was diagnosed in two patients with progressive system sclerosis. In one case, this was initially confused with a high fecal impaction. Both cases responded to early surgical intervention. Sigmoid volvulus should be considered in the differential diagnosis of intestinal obstruction associated with progressive systemic sclerosis.
