Treating Bile Duct Stones
The doctor passes the tube through the mouth and into the duodenum, then injects a contrast dye into the bile ducts, which can then be seen on x-ray.
Special tools can be guided through the endoscope to remove the stones..
Brush cytology can be a noninvasive means of diagnosing dysplasia and early carcinoma in those patients who are either asymptomatic or in those with minor symptoms who do not warrant immediate biopsy..
Biliary strictures may be benign or malignant.
Brush cytology is done during ERCP evaluation to assess the nature of the biliary strictures.
Obtaining brush cytology from a stricture is relatively safe and technically easy..
Common bile duct (CBD) brushing cytology is an important diagnostic method for the evaluation of pancreatic and biliary tracts abnormalities (1).
These abnormalities can be mostly caused by neoplastic or inflammatory processes (2).Aug 18, 2018.
Endoscopic retrograde cholangiopancreatography (ERCP) brush cytology is used frequently for sampling indeterminate biliary strictures.
Studies have demonstrated that the diagnostic yield of brush cytology for malignant strictures is estimated to be 6%–70%..
The bile duct brushings from adenocarcinoma usually reveal two distinct cell populations—benign and malignant
However, one can see a spectrum of malignant cells in the sample when the tumor exhibits a range of differentiation
Conclusions: Bile duct brushing cytology is highly specific in the detection of malignant pancreatobiliary lesions with few false positives, but has low sensitivity with many false negatives
Keywords: Bile duct brushing cytology; Diagnostic pitfalls; Histologic/FNAs correlation; Pancreatobilary disease; Sensitivity and specificity
Bile duct brushings (BDB) are the method of choice for pathological diagnosis of malignancy of the hepatobiliary system in our institution
We examined results of the cytological assessment of 267 BDB and compared them with biopsies, which were available in 131 cases
Sensitivity of BDB for diagnosi …
