Percutaneous transhepatic biliary biopsy using gastrofiberscopic biopsy forceps

Percutaneous transhepatic biliary biopsy using gastrofiberscopic biopsy forceps.

To obtain a histopathologic diagnosis at the site of a biliary obstruction, we recently have performed 24 cases of biliary biopsy using gastrofiberscopic biopsy forceps (Olympus, Tokyo, Japan) via transhepatic tracts provided in the course of the procedure of percutaneous biliary drainage. Histopathologic diagnosis was successfully made at the first attempt of biopsy procedure but a second tria...

Percutaneous visceral pleural biopsy with fenestrated cup biopsy forceps.

When there is an exudative pleural effusion often both the parietal and the visceral pleura are affected, but the usual practice is to perform a percutaneous parietal pleural biopsy alone for diagnosis. Percutaneous visceral pleural biopsy was carried out in 20 patients with exudative pleural effusions with fenestrated cup biopsy forceps. In all 20 biopsies pleural tissue was obtained and it wa...

PERCUTANEOUS TRANSTHORACIC BIOPSY USING TRU-CUT NEEDLE

Biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. A large-bore 14-gauge Tru-cut needle was used in all patients. Adequate specimens for histologic examination were obtained in 98%. The overall accuracy was 91 % with 9% false negative and no false positive diagnoses. Despite the large size of the needle, the total number of complic...

Percutaneous Transcatheteral Biliary Biopsy (PTBB)

Re: Forceps-related endoscopic transpapillary biliary biopsy programmes, reply: endoscopic biopsy techniques for proximal biliary strictures.

We read the paper by Meng et al. (1) entitled “Accurate biopsy of bile duct without destroying duodenal papilla” with great interest. They described a new technique to perform endoscopic biopsy in a 75-year-old male with a biliary stricture, which was presumed to be a malignancy, in the hilar region. They used a 7-Fr dilatation catheter (COOK, Winston-Salem, North Carolina, USA) and inserted it...
