Intestinal obstruction due to sigmoid volvulus during pregnancy is rare. The presenting signs/symptoms seen in these patients are the same as with non-pregnant patients. Fetal and maternal mortality rates are higher during pregnancy due to delays in diagnosis. We aimed to present four patients diagnosed with sigmoid volvulus during pregnancy and puerperium in our clinic. Diagnosis requires a high index of suspicion in a patient who presents with complaints of abdominal pain and evidence of bowel obstruction. Prompt intervention is necessary to minimize maternal and fetal morbidity and mortality.
