Pregnancy with sigmoid volvulus: A case report with literature review.

Sigmoid volvulus refers to torsion of a segment of the alimentary tract, which often leads to bowel obstruction and ischemic changes. Sigmoid volvulus is an acute surgical emergency because delay in diagnosis and management can cause adverse maternal and fetal complications. Sigmoid volvulus typically presents with acute-on-chronic abdominal distension that may develop slowly over 3-4 days.
