Abstract:
Video 1Details regarding the patient's clinical presentation and prior endoscopic treatments for common hepatic duct stricture are first described in the video. Next, the video features footage from subsequent ERCP demonstrating the common hepatic duct stricture both fluoroscopically and endoscopically via cholangioscopy, followed by treatment with thulium laser stricturoplasty/dissection. The immediate post-treatment images of the stricture are displayed which demonstrated marked improvement in the stricture. Finally, the patient's ensuing clinical course is displayed in which the stricture recurred and was retreated with laser stricturoplasty/dissection and stent upsizing.
