The current treatment of malignant biliary obstruction is non-surgical biliary diversion with palliative intent, the surgery having specific indications in patients with malignant pathology with curative intent. However, duodenal obstruction and non-dilated intra- or extrahepatic bile duct make these surgical and endoscopic procedures guided by EUS difficult. We present our experience with the first case in Colombia a third-world country in Latin America of a cholecystogastrostomy guided by EUS in a patient with unresectable pancreatic cancer and duodenal invasion with dilated common bile duct using a luminal stent (LAMS) (HOT stent AXIOS; Xlumena Inc., Mountain View, CA, USA) 15mm x 10mm.EUS-guided cholecystogastrostomy should be considered as an option for biliary decompression of greater importance than percutaneous drainage since it is superior in terms of technical feasibility, safety and efficacy in specific cases of ampullary stenosis and duodenal invasion. In addition, it can be done in third world countries when it has the appropriate training and implements. The fully covered metal stent applied to light (HOT AXIOS stent, Xlumena Inc., Mountain View, CA, USA) is ideal for EUS guided cholecystogastrostomy to minimize complications such as bile leakage. Additional comparative studies are needed to validate the benefits of this technique.
