“…2 Compared with anastomotic strictures, nonanastomotic strictures are frequently multilocular and might occur intrahepatically, making diagnostic assessment and treatment more complex. 2,3 In addition to noninvasive imaging, 22 ERC and cholangioscopy can be used for biliary stricture characterization and might help to exclude malignancy. 23 A recent meta-analysis included 283 SOVC procedures in unselected patients with an indeterminate biliary stricture, and optical signs had an excellent sensitivity and specificity in differentiating malignant strictures (sensitivity 94%, specificity 95%).…”

Background. Liver transplant recipients (LTRs) frequently develop biliary complications, and endoscopy is crucial for their subsequent management. Recently, single-operator video cholangioscopy (SOVC) with digital imaging quality was introduced. This study evaluated the utility of digital SOVC for the management of biliary complications in LTRs. Methods. This observational study retrospectively analyzed all LTRs undergoing digital SOVC between 2015 and 2019 at a tertiary referral center. Endpoints included the assessment of biliary strictures, performance of selective guidewire passage across biliary strictures, and diagnosis and treatment of biliary stone disease. Results. In total, 79 digital SOVCs performed in 50 LTRs were identified. Fifty-eight percent of the procedures were performed for biliary stricture assessment, and using visual signs or guided biopsies, SOVC excluded malignancy in all cases (100%). Of all the examinations, 29.1% (23/79) were performed solely because of a previous failure of conventional endoscopic methods to pass a guidewire across a biliary stricture. Using SOVC, guidewire passage was successfully performed in 73.9% of these examinations, enabling subsequent endoscopic therapy. Furthermore, biliary stones were found in 16.5% (13/79) of the examinations. In 38.5% of these cases, standard fluoroscopy failed to detect stones, which were only visualized using digital SOVC. Biliary stone treatment was successful in 92% (12/13) of the examinations. Complications occurred in 11.4% of all SOVCs. No procedure-associated mortalities were observed. Conclusions. Digital SOVC is effective and safe for the endoscopic management of biliary complications in LTRs and offers unique diagnostic and therapeutic opportunities that strongly impact the clinical course in selected cases.

“…We reviewed the published literature to assess the MRCP criteria of differentiating malignant from biliary strictures. As pe Nirhale et al, (1) , Shabanikia et al ., (19) , Wang et al ., (20) , Suthar . et al, (21) irregular, long, asymmetric, or abrupt narrowing of the biliary and/or pancreatic duct were considered as malignant features.…”

“…No restriction was detected in DWI of the strictures. Our findings of the benign CBD strictures kept with what was mentioned by Shanbhogue et al, (18) and Shabanikia et al ., (19) . In comparison to ERCP as a gold standard, MRCP gave for the diagnosis of benign biliary strictures 85.71% sensitivity, 100% specificity, 100% PPV, 94.74 NPV with an overall accuracy of 96%.…”

“…Our diagnosis based on the MRCP findings was periampullary carcinoma in both patients. Our findings kept with what was mentioned by Shabanikia et al ., 2021 (19) , Lee et al ., (24) , Ahualli , (27) and Agrawal and Vohra , (28) . The present study showed that 11.9 % of the patients with symptoms of obstructive jaundice had biliary strictures with features kept with the malignant strictures stated in the abovementioned literatures.…”

Background: Accurate methods of detecting pancreaticobiliary diseases for planning an effective management reveal a real need for less invasive and highly sensitive diagnostic procedure. Aim: highlighting the MRCP role in evaluating pancreaticobiliary abnormalities. Methods: The present study included sixty participants; a study group (42 symptomatic patients) and a control group (18 normal volunteers)-investigated with MRCP at Al-Ahrar teaching hospital, Sharkia, from June 2022 to April 2023. Results: We detected 90.48% of the symptomatic patients having peripheral bile tracts dilatation, where 88.1%, 90.48 and 78.57% had RHD, LHD and CHD dilatation respectively; with 73.81% had CBD dilatation. 33.33% had cholelithiasis whereas 19% showed cholecystitis, 30.95% had CBD stones with 7.14% had inserted CBD stents due to biliary stones whereas 38.1% of patients had neoplastic entities. In comparison to ERCP as a gold standard, MRCP-as regards the diagnosis of biliary stonesshows 100%sensitivity, 94.74%specificity, 92.31% PPV, 100% NPV with an overall diagnostic accuracy of 96.77%. Whereas, MRCP gave for the diagnosis of benign biliary strictures 85.71% sensitivity, 100% specificity, 100% PPV, 94.74% NPV with an overall accuracy of 96%. Conclusion: MRCP is a noninvasive diagnostic tool with a pivotal diagnostic role of pancreaticobiliary disorders.
