Volvulus of the right colon in pregnancy.

Intestinal obstruction in pregnancy is rare, volvulus being the commonest precipitating factor. It is a difficult diagnosis to make, because its symptoms mimic various pregnancy symptoms, but it commonly occurs in the third trimester or puerperium. A high index of suspicion is needed, and investigations for intestinal obstruction should be performed, especially when abdominal pain and vomiting persist. Careful evaluation of the abdominal cavity is also essential where a caesarean section is performed, particularly if there are unusual findings.
