title: [Gallstone ileus after endoscopic retrograde cholangiopancreatography].
abstract: BACKGROUND
  Gallstone ileus is caused by the exit of a gallstone from the gallbladder or bile duct into the small intestine, resulting in bowel obstruction if this stone becomes lodged in a small bowel loop.
  
  
  METHODS
  The case is presented of a 78 year-old woman with an episode of intestinal obstruction. After studying the main cause of the obstruction, it was decided to perform a laparotomy where a gallstone located in the terminal ileum was causing the obstruction. No fistula was observed between the gallbladder and the bile duct and the intestinal tract. It is important to note the history of an endoscopic retrograde cholangiopancreatography performed a few months earlier, as it would probably be the cause of the passage of the gallstone to the small bowel.
  
  
  CONCLUSIONS
  Few reports of gallstone ileus have been described in the literature after performing an endoscopic retrograde cholangiopancreatography. In these cases, the intestinal obstruction usually occurs several months after the endoscopic retrograde cholangiopancreatography, so the diagnosis is often delayed. Surgery is usually the definitive treatment and it consists of the removal the stone by enterotomy and performing a cholecystectomy. Biliary enteric fistula repair is not necessary since this does not form.
