ALFARO-ALONSO, Ricardo Juan  y  ESCAIG-OLIVARES, René Luis. Biliary ileus, an unusual cause of intestinal obstruction. Rev.Med.Electrón. [online]. 2023, vol.45, n.3, pp. 512-519.  Epub 30-Jun-2023. ISSN 1684-1824.

Biliary ileus is a rare complication of gallbladder lithiasis, which behaves like a mechanic intestinal obstruction, the cause of which is the impaction of one or more gallstones in its lumen. It is evident that because of the infrequency of this entity in the surgical services, its diagnosis is delayed or not carried out, affecting the patient’s evolution in an unfavorable way. The aim of this paper is to consider that a precocious diagnosis of biliary ileus-based on the analysis of the patient’s history, the clinical manifestations and correct interpretation in search of the signs of Rigler’s triad-allows a better evolution of patients. Imaging studies and their interpretation are fundamental in the diagnosis of this entity.

Palabras clave : impaction; intestinal obstruction; cholelithiasis; biliary ileus; duodenal bulb.
