title: [Mega-duodenum and constipation after surgery for congenital atresia of the jejunum].
abstract: A 33 year-old female presented with constipation and a right-sided palpable abdominal mass, suspected to be the colon. The colonic transit time was prolonged, but the dilated organ was a mega duodenum that had developed after surgery for three jejunal atresies performed one day after birth. The colon was malrotated, being situated to the left of the columna. Renewed resection surgery was uneventful, and after such surgery the constipation receded and the colonic transit time returned to normal.
