Abstract:
Objective To study pathological diagnostic value of forceps and brush biopsy cytological examination by percutaneous transhepatic cholangiodrainage(PTCD) for malignant obstructive jaundice.Methods From April 2005 to April 2006,24 cases of obstructive jaundice underwent PTCD and stent insertion in biliary tract.Tissue pathological examination by forceps and brush was done during PTCD.Results 24 cases received forceps biopsy,of whom,14 cases received brush cytological examination at the same time.All of the 24 cases of forceps biopsy obtained pathological tissue and the pathological results as follows: adencarcinoma in 15 cases,4 cases had allotype cells,regarded as positive results;inflammation tissue in 1 case,which was restenosis after stent insertion;fibrous tissue in 1 case;tissue obtained was cholangioepithelia in 3 cases,in which 1 case was diagnosed as lymph node metastasis of peripheral head of pancreas after gastric cancer operation,2 cases were diagnosed as cholangiocarcinoma,the positive rate of forceps biopsy being 79.2%(19/24).4 cases of cytological examinations by brush showed tumor cells in 2 cases,allotype cells in 2 cases,regarded as positive results,the positive rate being 28.6%(4/14),and others were negative results.Conclusions Intracholangio-biopsy by PTCD offers the advantages of simplicity,safety,higher accuracy and less complications.Pathological diagnosis can be obtained at the same time during reducing-jaundice therapy by PTCD.
