[Chronic idiopathic intestinal pseudo-obstruction associated with volvulus of the transverse colon. The identical mode of clinical presentation and of the intestinal manometric pattern in monozygotic twins].

Two monozygotic female twins with chronic idiopathic intestinal pseudo-obstruction associated with transverse colon volvulus are described. Quite similar clinical events and temporal coincidences characterized the symptoms which has preceded and followed right colectomy undergone by both of them due to intestinal volvulus. The esophageal, gastroduodenal, colonic and anorectal manometric investigation revealed very similar alterations in both girls. Increased amplitude of distal contractions of the esophagus, a depressed fasting antro-duodenal motility, with absence into antrum and oro-aboral non-propagation in the duodenum of the phase III activity of the interdigestive motor complex were the main findings along with a state of pronounced colonic hypomotility and an hypoesthesia of the rectal ampulla to the volumetric stimulus. This report indicates the association between chronic intestinal pseudo-obstruction and transverse colon volvulus in monozygotic female twins, and it points out the rarity both of the specific symptomatic coincidences and the similar clinical events and of the almost absolute identity of the intestinal motor patterns.
