Situs inversus totalis (SIT) is a rare congenital deformity involving complete transposition of all of the viscera. Endoscopic retrograde cholangiopancreatography (ERCP) is challenging in patients with SIT owing to anatomical anomalies [1]. Here we present the case of a patient with SIT who successfully underwent biliary cannulation by ERCP using a novel rotatable sphincterotome.

An 83-year-old woman with obstructive jaundice due to advanced gallbladder cancer was referred to our hospital. Abdominal computed tomography showed transposition of the liver and gallbladder to the left upper quadrant and distal biliary obstruction owing to lymph node metastasis ([Fig. 1]).

ERCP was performed with the patient in the usual prone position; the endoscopist was on the left side of the table. The duodenoscope was advanced into the second portion of the duodenum, and the papilla was oriented to the right at the 1-o’clock position ([Fig. 2]). Biliary cannulation was attempted using a conventional ERCP catheter but was unsuccessful. To adjust the biliary axis, a novel rotatable sphincterotome (TRUEtome, Boston Scientific, Marlborough, Massachusetts, USA) was used. The TRUEtome is a sphincterotomy device that allows vertical and horizontal rotation of the tip ([Fig. 3]). Biliary cannulation was successfully achieved by moving the catheter tip to adjust the biliary axis ([Fig. 4]; [Video 1]). Following biliary cannulation, endoscopic sphincterotomy was performed using the TRUEtome, and a self-expandable metal stent (ZEOSTENT Plus; Zeon Corporation, Tokyo, Japan) was deployed to cover the biliary stricture ([Fig. 5]). No procedure-related adverse events were noted, and the patient’s jaundice resolved within a few days.

There have been reports of successful ERCP in patients with SIT by making a change in the patient position or the endoscope insertion location [2] [3] [4]. The present case indicates that a rotatable sphincterotome is a useful device that enables biliary cannulation in patients with SIT by vertically and horizontally adjusting the catheter tip with the patient in the conventional position and the usual scope insertion location.
