Duplications of the gastrointestinal (GI) tract are rare. Only 5% of them are rectal and there are very few reports of rectal prolapse (RP) caused by a duplication. An 11 month-old female presented with a RP caused by a blind-ended anterior tubular colorectal duplication. The duplication was successfully opened and connected to the normal rectum without complications. Although infrequent, a rectal duplication should be considered in the differential diagnosis of RP.
Mesenteric cysts are infrequent and can be located anywhere in the gastrointestinal tract. They can be single or multilocular and measure up to 30 cm in diameter. A 14-year-old female presented with pain in the left iliac fossa. Physical examination revealed a movable and painful tumor, not adhering to deep planes, of 15 cm×15 cm. On surgical intervention, the report was as follows: a mesentery cyst 30 cm long, adhered to the greater curvature of the stomach, lodged in the pelvic hollow and left iliac fossa. This report exemplifies a case concordant with a mesentery cyst in an unusual location.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
