Situs ambiguus, or heterotaxy, is a rare syndrome characterized by an abnormal arrangement of the internal organs in the chest and abdomen and is usually associated with congenital heart diseases. Despite its variable presentation, heterotaxy syndrome can be classified into heterotaxy with polysplenia or left isomerism, and heterotaxy with asplenia or right isomerism. The different imaging techniques reveal the characteristic imaging findings that allow an accurate description of each patient's specific anatomy. Evaluation of the position of the following structures relative to midline is crucial: atria, cardiac apex, venous drainage, aorta, stomach, liver and gallbladder, as well as the presence or absence of intestinal malrotation, number of spleens, and presence of tri-or bilobed lungs. We present a case report of a 42-year-old man with dextrocardia underwent laparoscopic cholecystectomy for cholelithiasis. Subsequently, a complete resection of the common bile duct required reconstruction of the biliary tract. During six years the patient underwent frequent examinations for recurrent episodes of cholangitis that required stenosis dilation and biliary stent placement using endoscopic retrograde cholangiopancreatography. Despite these treatments, the patient required surgery again for biliary stenosis, this time a bilioenteric anastomosis (Roux-en-Y) was performed. During the surgical procedure migration of the biliary stent occurred.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
