    Description

    Acute cholecystitis is inflammation of the gallbladder. It usually happens when a gallstone blocks the opening that drains bile from the gallbladder. Bile builds up, causing nausea, vomiting and fever. In this procedure, a flexible tube called an endoscope is passed through the mouth and into the stomach or the first part of the small intestine. Using ultrasound to identify the gallbladder, a small tube (a stent) is inserted via the endoscope through the wall of the stomach or small intestine into the gallbladder. Bile flows through the stent. The aim is to drain bile from the gallbladder.
