Abstract:
Objective To investigate the endoscopic ultrasound (EUS) features of distal biliary stricture (DBS), and to provide a clinical basis for the evaluation of DBS by EUS. Methods Related clinical data were collected from 175 patients with DBS who underwent EUS examination in The First Affiliated Hospital of Anhui Medical University from April 2016 to March 2020 to analyze their clinical manifestation, laboratory examination results, imaging findings, and EUS findings, and the patients were followed up to summarize the EUS features of DBS. The chi-square test was used for comparison of categorical data between groups, and the t -test was used for comparison of continuous data between groups. Results Among the 175 patients with DBS, 85(48.57%) had benign DBS and 90(51.43%) had malignant DBS. Compared with the patients with benign DBS, the patients with malignant DBS had a significantly longer length of stricture on EUS (14.1±3.0 mm vs 7.9±3.0 mm, t =13.358, P < 0.001) and significantly higher incidence rates of the characteristic changes on EUS such as hypoechoic space-occupying lesions in lumen (57.8% vs 34.1%, χ 2 =9.843, P =0.002), peripheral lymph node enlargement (26.7% vs 12.9%, χ 2 =5.147, P =0.023), and pancreatic duct dilatation (51.1% vs 28.2%, χ 2 =9.532, P =0.002). EUS combined with magnetic resonance cholangiopancreatography had a sensitivity of 70.6% in the diagnosis of benign DBS and a sensitivity of 92.2% in the diagnosis of malignant DBS. Conclusion The characteristic EUS features of DBS, such as long length of stricture, hypoechoic lesion, peripheral lymph node enlargement, and pancreatic duct dilatation, may help with the differential diagnosis of DBS in clinical practice.
