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.
