Technique for ERCP and Stent Placement in a Patient with Situs Inversus Totalis and Splenosis

Abstract

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by the transposition of thoracic and abdominal organs in a mirror image. Performing endoscopic retrograde cholangiopancreatography (ERCP) in patients with SIT is much more difficult than in patients with normal anatomy due to the different orientation of the bile duct axis. This article describes the first known description of successful ERCP and the placement of a choledocal stent in a patient with SIT and malignant choledocal stenosis using an adjusted technique to accommodate the circumstances.
