MANRIQUE, María  and  MARTIN-M, Wilmar. Biliodigestive shunt guided by endoscopic ultrasonography in patient with stage IV pancreatic adenocarcinoma and obstruction of the bile duct. A case report. Rev. colomb. Gastroenterol. [online]. 2021, vol.36, n.1, pp.120-125.  Epub Oct 21, 2021. ISSN 0120-9957.  https://doi.org/10.22516/25007440.490.

Endoscopic endosonography is an alternative to guide biliodigestive shunting in cases where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Techniques such as choledoduodenostomy or choledochoantrostomy guided by endoscopic ultrasonography have been described.

This is the case of a 72-year-old patient with pancreatic adenocarcinoma, portal vein and duodenal wall involvement, in whom ERCP to try a palliative shunt failed. Therefore, a metal stent was placed using endoscopic endosonography, with adequate clinical response to the procedure and treatment. It is concluded that the procedure is safe and that endosonography is an effective alternative in cases of ERCP failure to achieve biliary bypass in cases of malignant biliary obstruction.

Keywords : Bile duct obstruction; Retrograde endoscopic cholangiopancreatography (ERCP); Endoscopic ultrasonography (EUS).
