Ileo biliar: breve revisión a propósito de dos casos clínicos / Biliary ileus: brief review on purpose of 2 clinical case

ABSTRACT

Gallstone ileus is not frequent, responsible for 1-3 percent of mechanical intestinal obstructions. Its incidence increase considerable with age, being more frequent in women. In its pathogenesis a stone migrates from the gallbladder to the intestinal lumen through and entero-biliary fistula, usually of the cholecystoduodenal type, impacting in the lower ileum. Clinical manifestations correspond to that of a mechanical ileus, which evolves insidiously with partial recovery periods. The diagnosis is established by clinical suspicion, abdominal plain film and ultrasound. Clinical suspicion has the highest predictive value. The treatment is eminently surgical, although there is still debate about the best moment to repair the biliary tract. We present 2 clinical cases
