“Triple duodenal obstruction” complicated with intestinal malrotation and several cardiovascular malformations

Abstract

Triple duodenal obstruction is an extremely rare disorder—apparently only two cases were reported in the English literature. We present a third case complicated with some cardiovascular anomalies (interrupted inferior vena cava, left-sided inferior vena cava, preduodenal portal vein, and ventricular septal defect) and intestinal malrotation. Operative procedure to reconstruct continuity of the duodenal lumen was a combination of longitudinal incision, partial web resection, and transverse closure at the first obstruction site together with diamond-shaped duodeno-duodenostomy between the oral side of the second obstruction and the anal side of the third obstruction.
