Endosonography-guided Gallbladder Drainage vs Non-endoscopic Treatment in Inoperable Acute Cholecystitis

The placement of a endoscopic drain performed using a linear echoendoscope that allows the gallbladder to be punctured from the gastric antrum or the duodenal bulb to generate a cholecystogastrostomy or a cholecystoduodenostomy, respectively. Transmural gallbladder drainage will be performed by placing a metal apposition stent (LAMS) with the 15x15mm Hot AXIOS device (Boston Scientific) in the case of cholecystogastrostomy or 15x10 or 10x10mm in the case of cholecystoduodenostomy. Subsequently, the interior of the gallbladder will be irrigated with saline solution until the vesicular content comes out.
