Abstract:
Objective To compare the sensitivity between forceps biopsy and brushing, and to explore a feasible approach to pathological diagnosis of the obstructive jaundice.Methods 92 consecutive patients with obstructive jaundice underwent transluminal foreceps biopsy and brushing during percutaneous transhepatic cholangiography and percutaneous transhepatic cholangiodrainage. The technique was performed through an preexisting percutaneous transhepatic tract with multiple specimens obtained after passing the forceps biopsy or brush into a 8-French sheath. Finally the specimens were fixed with formalin for pathologic or cytologic diagnosis. Results The histopathologic diagnosis was acquired in 81 out of 92 patients with forceps biopsy reaching the successful rate of 97.83%. Sensitivity of forceps biopsy in 92 patients was higher than that of brush in 84 patients(88.04% vs 76.19%,? 2=4.251,P=
