Abstract:
Objective To analyze the multi-slice spiral CT (MSCT) combined negative helical CT cholangiography (N-CTC) technical inspection applications in diagnosis of the biliary duct obstruction diseases.Methods Retrospective analysis of clinical data of 72 patients admitted to hospital by MSCT combined with N-CTC technical inspection and confirmed by pathology or surgery in patients with biliary duct obstructive diseases,and compared with pathological findings.Results Seventy-two cases had 81 paragraph obstruction lesions,with the biliary obstruction of pancreatic head to the level of duodenal ampullary were more common,a total of 44 (54.3％,44/81);among the 216 biliary paragraph,the missed diagnosis rate of MSCT combined with N-CTC was 9.9％ (8/81),and misdiagnosis rate of obstruction was 4.4％ (6/135),MSCT combined with N-CTC technology in diagnosis of biliary duct obstruction in comparison with surgical or pathological had no significant difference (P ＞ 0.05).MSCT combined with N-CTC easily missed small low-density stones.Conclusions MSCT combined with N-CTC can clearly positioning biliary duct obstruction and qualitatively,consistency with surgery or pathological diagnosis is good,it is practical,non-invasive,can be used as the first choice for suspected biliary duct obstruction means of inspection,has a wide range of applications.
