The SpyGlass DS system is currently used as a direct video cholangioscope for biliary diagnostic and therapeutic procedures. In general, the SpyGlass DS cholangioscope is passed through the working channel of a duodenoscope and inserted into a bile duct via duodenal papilla. However, the procedure has been challenging in patients with altered gastrointestinal anatomy due to the retrograde route through a potentially tortuous afferent limb. A therapeutic colonoscope with variable stiffness can offer alternative guidance for SpyGlass DS cholangioscope in patients with surgically altered gastrointestinal anatomy.
SpyGlass DS系统目前用作胆道诊断和治疗程序的直接视频胆管镜。一般来说，SpyGlass DS胆管镜通过十二指肠镜的工作通道，经十二指肠乳头插入胆管。然而，对于胃肠道解剖结构改变的患者，由于要通过可能迂曲的输入袢逆行进入，该操作具有挑战性。对于胃肠道解剖结构因手术改变的患者，一种具有可变硬度的治疗性结肠镜可为SpyGlass DS胆管镜提供替代引导。
