Objective:To study the combined use of endoscopic balloon dilation with endoscopic biliary brushings in diagnosis of bile duct strictures.Methods:A prospective single center study was conducted at the Central Hospital of Wuhan, Tongji Medical College, Huazhong University of Science and Technology. All patients with suspected malignant bile duct strictures shown on CT or MRI imaging from January 2018 to January 2020 were reviewed. All patients gave informed consent to the endascopic retrograde cholangiopancreatography procedures. Their clinical and follow-up data were analyzed. All patients underwent endoscopic balloon dilation of bile duct strictures. Before and after balloon dilation, biliary brush cytology was performed, and the results were used to classify the patients into the control group and the experimental group. Pathological examination of the brush cytology samples was carried out by a single chief pathologist. Presence of cancer cells or significant heterogeneous cells indicated a positive brush cytology test. Negative patients who still highly consider cholangiocarcinoma and agree to surgery and whose gross specimen is confirmed to be malignant after surgery should be considered as false negative by brush examination; it is difficult to judge that patients with cholangiocarcinoma have progress after 2 months of follow-up should be considered as false negative by brush examination. Any progression of disease indicated that the brush test was wrong and the test was again classified as false negative. Only when there was no progression of strictures was the possibility of a benign biliary stricture being considered. The advantage test (McNemar test) was used to analyze the difference between the two diagnostic methods.Results:Of 39 patients who were included in this study, there were 26 males and 13 females, with an age of (68.0 ± 5.2) years. Cholangiocarcinoma was diagnosed by histopathology, surgery or at 2 months follow-up in 35 patients. In the control group, 17 patients had a positive brush test (sensitivity rate was 48.6%, 17/35). In the experimental group, 26 patients had a positive brush test (sensitivity rate was 74.2%, 26/35). In addition, 2 patients in the control group had a positive brush test, while in the experimental group, a negative brush test. A total of 28 patients were positive in the two groups. The sensitivity rate of the brush test was 80.0% (28/35). There were significant differences between the two groups ( P<0.05). Conclusion:Endoscopic balloon dilation combined with endoscopic biliary brushings improved the sensitivity of pathological diagnosis of cholangiocarcinoma, and endoscopic biliary brushings before and after balloon dilation improved the sensitivity of diagnosis.
