Objectives: 1. Comment image characteristics and the role of ultrasound, magnetic resonance in the diagnosis of biliary stones with surgery; 2. Early evaluation results for the surgical treatment of biliary stones at the Bach Mai Hospital. Patients and Methods: Patients included 69 male: 50.7 percent female: 49.3 percent underwent surgery at the Department Surgical of the Bach Mai hospital from 01/06/2012 to 06.30.2013. Research methodology: method consists of two stages described retrospective 22 patients and prospective 47 patients. Results: Mean age was 56.6 + or - 16,642 years old (24-88), 40 years and older is 75.4 percent. Features images gravel: gravel on. ultrasound image amplification is 81.1 percent) and biliary stretch is 100 percent, with 18.8 percent of commun ducd is thick. Image and biliary stones on MRI: 100 percent stretch molasses are rendering in MRI signal decrease in bile 100 percent and 100 percent increase in T1-T2, 52.2 percent are gravel shores), uneven gravel shores 33 patients (47.8 percent). Gravel up and down signal on Tl-weighted images and T2-weighted different. Surgical Results: endoscopic is 19 percent and 81 percent is open. Sewing commun ducd rate is 19 percent and 81 percent drain Kehr. Complications: 2.8 percent. Complications: 7.2 percent. Good results are 71.1 percent, average 24.6 percent, negative 4.3 percent. Conclusion: The role of ultrasound, MRI in the diagnosis of biliary stones: The role of ultrasound: sensitivity (Se) is 90.16 percent specificity (Sn) is 87.50 percent, in Diagnosis commun ducd stretch sensitivity (Se) is 100 percent. - The role of MRI: sensitivity Se is 98.38 percent, specificity is Sp (87.50 percent). The positive predictive value was 98.38 percent PPV. Negative predictive value was 87.50 percent NPV. The accuracy is 89.85 percent.
