ABSTRACT
In most omphalopagus twinnings, joined structures include the gastrointestinal tract, liver, biliary tree and bladder. In some instances of omphalopagus, joined attachments are limited to the intestine and bladder. Eight cases like these, that are also called minimally conjoined twinning, have been reported before. This article describes a set of twins who were joined by an omphalocele sac and small bowel. There were several loops of bowel in the conjoined omphalocele sac without any evidence of liver. One of the twins had atresia of the colon, rectum and anus and the other had a cloacal anomaly. The twins were separated at the 18th hour after birth due to intestinal obstruction. One of the twins survived, but the other died on the second day postoperatively.
