Sin ictericia o dilatación de la vía biliar, el diagnóstico es en extremo difícil de sospechar; es posible que sean diagnosticados durante la cirugía o tiempo después de la misma. La colangiorresonancia o colangiopancreatografía retrógrada endoscópica se reserva para los casos con alto índice de sospecha de coledocolitiasis. No se realizan de rutina.  Objetivos:  Conocer los factores de riesgo de la coledocolitiasis asintomática en pacientes operados de colecistectomía laparoscópica.  Material y métodos:  Se realizó un estudio prospectivo, analítico, comparativo en pacientes a quienes se realizó colecistectomía laparoscópica sin evidencia clínica o radiología para sospechar coledocolitiasis. Con base en la colangiografía transoperatoria, se dividieron en dos grupos: sin coledocolitiasis y con coledocolitiasis. Se consideró p &lt; 0.05 como estadísticamente significativo.  Resultados:  53 mujeres (77.9%) y 15 hombres (22.1%). La fosfatasa alcalina (FA) fue el único parámetro con diferencia significativa entre los grupos (p = 0.034). Con FA &gt; 90.5 U/l hubo un riesgo 12.4 veces mayor de presentar coledocolitiasis asintomática, con sensibilidad y especificidad de 80%.  Conclusiones:  La coledocolitiasis asintomática en el Hospital General de México es del 13.2%. Cuando un paciente con colelitiasis, sin ictericia y sin dilatación ultrasonográfica de la vía biliar tiene FA &gt; 90.5 debemos sospechar la presencia de coledocolitiasis asintomática.]]></p></abstract>

Without jaundice or dilation of the bile duct, the diagnosis is extremely difficult to suspect; it is possible for them to be diagnosed during surgery or time after it. Cholangioresonance or endoscopic retrograde cholangiopancreatography are reserved for cases with a high index of suspicion of choledocholithiasis. They are not performed routinely.  Objective:  To know the risk factors for asymptomatic choledocholithiasis in patients undergoing laparoscopic cholecystectomy.  Material and methods:  A prospective, analytical, comparative study was performed in patients who underwent laparoscopic cholecystectomy without clinical or radiological evidence to suspect choledocholithiasis. Based on the transoperative cholangiography, they were divided into two groups: without choledocholithiasis and with choledocholithiasis; p &lt; 0.05 was considered statistically significant.  Results:  53 women (77.9%) and 15 men (22.1%). Alkaline phosphatase (AP) was the only parameter with significant difference between the groups (p = 0.034). With AP &gt; 90.5 U/l, there was a 12.4-fold greater risk of presenting asymptomatic choledocholithiasis, with sensitivity and specificity of 80%.  Conclusions:  Asymptomatic choledocholithiasis in the General Hospital of Mexico is 13.2%. When a patient with cholelithiasis, without jaundice and without ultrasonographic dilation of the bile duct has AP &gt; 90.5, we should suspect the presence of asymptomatic choledocholithiasis.]]></p></abstract>
