Title: Obstruction of the duodenum by a preduodenal portal vein in situs inversus. Author: Duncan ND, Trotman H, Seepersaud M, Dundas SE, Thame M, Antoine M. Journal: West Indian Med J; 2007 Jun; 56(3):285-7. PubMed ID: 18072415. Abstract: Mirror image transposition of abdominal and thoracic viscera is termed situs inversus. Duodenal obstruction in situs inversus is rare. A preduodenal portal vein, though not uncommon in situs inversus, rarely causes duodenal obstruction. Where obstruction by a preduodenal portal vein is diagnosed, a duodeno-duodenostomy is the recommended treatment. A duodenal diaphragm and other more common causes of duodenal obstruction should also be excluded in these patients.[Abstract] [Full Text] [Related] [New Search]
