Highlights: Case Study Article, Video a Window into Next-generation Duodenoscope
The second aspect of interest is how navigating complex anatomy works with the features intended to improve visibility. The TJF-Q190V provides a 15-degree backward “extra” view, compared to the TJF-Q180V.
Dr. Hasan walks viewers through a sphincterotomy in this case, using the Olympus CleverCut3V™ Sphincterotome. The bile duct stone removal demonstrates how balloon dilation “can be tricky,” as he puts it, and he also explains his rationale for his balloon size choice.
Cannulation struggles, stent deployment
In the second case, the patient has a diagnosis of pancreatic adenocarcinoma. According to Dr. Hasan, this is another case in which the TJF-Q190V is beneficial. The square image “gives me a better-quality image, a superior image as compared to the [TJF-Q180V] scope,” he said.
Dr. Hasan says he often performs a sphincterotomy before deploying metal stents out of “concern for a blocked pancreatic orifice.” Hasan chose to use the Olympus HANAROSTENT™ Biliary metal stent featuring a hook-and-cross wire pattern, designed so that “if you compress the center [of the stent] it will not elongate.” After a successful deployment, he adds, “It just spreads like a flower at both ends.”
