OBJECTIVE: to determine the incidence, frequency of risk factors, diagnostic aspects (clinics, biochemical, and images) and therapeutic aspects of the choledocholithiasis. PATIENTS AND METHODS: Descriptive and prospective analysis of 51 patients who signed informed consent for study of choledocholithiasis by ERCP (endoscopic retrograde cholangiopancreatography). RESULTS: Of the 51 patients, 36 (70.6%) confirmed choledocholithiasis by ERCP. Its incidence was 10.4%. The mean age was 63.75 years, BMI 25.59 kg/m2 and 55.6% were women. Abdominal pain was present in 94.4% of patients. Total bilirubin in the group with choledocholithiasis was 5.8 mg / dl at baseline and 4.2 mg / dl in hospitalization. 11.1% debuted with pancreatitis and 30.6% with cholangitis. In 68.7% of patients with cholangitis was confirmed choledocholithiasis by ERCP. The specificity of ultrasound was 0.80 (95% CI 0.6- 1). The specificity of the nuclear magnetic resonance was 0.25 (95% CI 0.17-0.67). Of the 51 patients with ERCP, 4 (7.80%) do pancreatitis, 1(1.96%) cholangitis and 2 (3.92%) bleeding CONCLUSIONS. Choledocholithiasis occurs in older people, female and overweight with an incidence of 10.4%. Abdominal pain is the most common symptom. A total bilirubin more than 4mg/dl occurs in patients with choledocholithiasis. The complications of choledocholithiasis (pancreatitis and cholangitis) were more frequent than reported in the literature. Both the specificity of cholangitis for choledocholithiasis, the specificity of ultrasound and the specificity of the nuclear magnetic resonance were lower than reported in the literature. ERCP complications were slightly higher than that reported in the literature.
