Transverse colon volvulus in children: A case series and a review of the literature.

Volvulus of the transverse colon is very rare in children. Three cases that occurred in a short time span are described and the scarce literature is reviewed. All patients presented with colonic obstruction and in all three the condition was diagnosed at laparotomy, as CT-scanning is not an available option in either of the two institutions. The transverse colon had not become gangrenous but was resected after detorsion for redundancy. The postoperative course was complicated and relaparotomy had to be performed for reobstruction in all cases. Only if the 'reverse' bean sign is recognized on the preoperative plain abdominal radiograph this rare diagnosis can be suspected.
