Volvulus of the splenic flexure of the colon. In a patient with a markedly dilated splenic flexure‚ this ostevacuation film from a barium enema reveals the classic riss-crossing mucosal fold pattern (arrows) of a volvulus. In his patient‚ there was an elongated left colon on a ersistent mesentery‚ a lack of proper resorption.
A double-contrast barium enema reveals a short descending olon with a long, redundant transverse colon. This epresents incomplete fusion of the descending colon esentery, with its remnant allowing excessive mobility. In ddition, the cecum is pointed superiorly in the right upper uadrant, which represents premature arrest of the ostarterial rotation. Therefore, this patient has a not ncommon combination of incomplete rotation and alfixation.
