Abstract:
Objective To explore the diagnostic value of percutaneous transhepatic cholangial biopsy for malignant obstructive jaundice.Methods Data of 42 cases suspected of malignant obstructive jaundice who underwent percutaneous transhepatic cholangial biopsy and percutaneous transhepatic cholangial drainage (PTCD) were retrospectively analyzed.And during the examination,the biopsy tissues were obtained for pathology.Results The pathologic results were obtained successfully in 41 of 42 cases and the success rate of operation was 97.62％ (41/42).There were 31 cases with positive results.The positive rate was 73.81％ (31/42).In 12 cases diagnosed as distal biliary tract obstruction by percutaneous transhepatic cholangiography (PTC),positive pathology results were found in 3 cases;the positive rate was 25.00％ (3/12).In 30 cases diagnosed as perihilar biliary tract obstruction by PTC,positive pathology results were found in 28 cases;the positive rate was 93.33％ (28/30).The accuracy of perihilar biliary tract obstruction was higher than that of distal biliary tract obstruction (x2=20.704,P＜0.05).In all 42 cases,there were no severe complications during or after surgery.In the 31 cases with positive biopsy pathological results,6 cases underwent surgery after improved liver function.The postsurgical pathological results were agree with biopsy pathological results.Conclusion Percutaneous transhepatic cholangial biopsy is safe and efficient for malignant obstructive jaundice.The successful rate and positive rate are high,especially for perihilar biliary tract obstruction.
