Íleo biliar: Reporte de un caso de fístula colecistoduodenal asociada a hernia inguinal izquierda

Abstract

Biliary ileus, first described by Thomas Bartholin in the year 1654, is a rare cause of mechanical ileus (small bowel obstruction) (1-3% in patients younger than 65 years), increasing significantly from that age (25%). The necessary condition for this pathology is the presence of a fistula between the gallbladder and the gastrointestinal tract. Simple abdominal X-ray and ultrasonography are widely available and of relatively low cost, together presenting a sensitivity of 74% when they show the classic signs of Rigler’s triad (pneumobilia, ectopic gallstone and dilated loops of small intestine), but computed tomography of the abdomen is considered the gold standard, with a sensitivity and specificity higher than 90%. The aim of this article is to present a case of radiological diagnosis of biliary ileus in a patient with vesicular lithiasis + cholecystoduodenal fistula, associated with inguinal hernia on the left.
