Congenital midgut malrotation causing intestinal obstruction in midpregnancy managed by prolonged total parenteral nutrition: case report and review of the literature

Background: A review of the English literature from 1980 to 2010 revealed only six gravidas managed by total parenteral nutrition (TPN) for at least 16 weeks of pregnancy. We found only two gravidas with obstruction due to malrotation, both managed surgically. Case: We report a unique case of bowel obstruction presenting in the second trimester due to congenital malrotation of the small intestine that was conservatively managed by prolonged TPN, with the delivery of a healthy term baby girl. Surgical correction was delayed until the patient was not pregnant. Conclusion: Intestinal obstruction in pregnancy is rare, and malrotation of the small bowel as the cause is extremely rare. This is the first case of intestinal obstruction in midtrimester in which prolonged TPN was employed when surgery was contraindicated. TPN may be considered if surgery cannot be performed, with an excellent outcome likely.
