Sigmoid volvulus in advanced pregnancy. Report of 2 cases.

Abstract

Two cases of sigmoid volvulus complicating pregnancy at 33 and 26 weeks' gestation are reported. The clinical presentations were strikingly similar, although the second patient presented later in the evolution of the condition and died 6 hours after surgery. Both fetuses died in utero. The reasons for suspecting sigmoid volvulus as a cause of intestinal obstruction (especially in pregnant black women) and its management are outlined.
