Small bowel obstruction due to congenital adhesion bands during pregnancy

Abstract

Small bowel obstruction due to congenital adhesion bands is a very rare occurrence during pregnancy, but is associated with significant fetal and maternal mortality. A 24-year-old primigravida woman, without previous abdominal surgeries, was referred to the emergency department at 35 weeks of gestation with the complaint of sudden abdominal pain. Abdominal magnetic resonance imaging revealed multiple loops of dilated small intestine and adhesion bands in the distal jejunum. The decision was made to proceed with a cesarean delivery and to explore the abdomen to determine the cause of the small bowel obstruction. A 2,680-gram male baby with a 7/9 Apgar score was delivered. A fibrotic band between the jejunal mesentery and distal jejunum caused the small bowel obstruction. After release of the adhesive band, the bowel regained its color and was viable. No adverse event developed in the mother or baby during a 1-year period. Although congenital bands are very rare in pregnant women, they can cause serious maternal and fetal mortality due to the delayed diagnosis and treatment, and physicians should be aware of this clinical condition.
