A single-operator cholangiopancreatoscopy was developed to overcome a problem in conventional peroral cholangiopancreatoscopy. The aim of this pilot study was to clarify the clinical utility of single-operator cholangiopancreatoscopy using a SpyGlass probe through an endoscopic retrograde cholangiopancreatography (ERCP) catheter.
Patients undergoing ERCP with a SpyGlass probe passed through a catheter were included in this study. The SpyGlass probe was inserted into the catheter following successful cannulation, and cholangiopancreatoscopy was performed by a single operator. We retrospectively analyzed the successful visualization rate of this technique.
Fifteen patients were included in this study. SpyGlass cholangiopancreatoscopy was technically successful in all patients. Successful visualization was obtained in nine patients (60%). The median SpyGlass procedure time was 10 min. Cholangiopancreatoscopic diagnoses were as follows: bile duct carcinoma in three patients; intraductal papillary mucinous adenoma in two; and intraductal pancreatic stone, benign biliary stricture, gallbladder cholesterolosis, and gallbladder carcinoma in one each. There were no cases of post-ERCP pancreatitis.
While the low rate of successful visualization must be improved, single-operator cholangiopancreatoscopy using a SpyGlass probe through an ERCP catheter is a safe and effective procedure.
为解决传统经口胰胆管镜检查的一个问题，开发了单操作员胰胆管镜。本研究的目的是通过经内镜逆行胰胆管造影（ERCP）导管使用SpyGlass 探头阐明单操作员胰胆管镜检查的临床实用性。
本研究纳入了接受 ERCP 联合 SpyGlass 探头检查的患者。成功插管后，将 SpyGlass 探头插入导管内，由单操作员进行胰胆管镜检查。我们回顾性分析了该技术的成功可视化率。
本研究共纳入 15 例患者。所有患者的 SpyGlass 胰胆管镜检查均在技术上获得成功。9 例（60%）患者成功进行了可视化检查。SpyGlass 操作的中位时间为 10 分钟。胰胆管镜检查诊断结果如下：3 例胆管癌；2 例胰胆管内乳头状黏液腺瘤；1 例胰胆管内结石、良性胆管狭窄、胆囊胆固醇沉着症和胆囊癌。无 ERCP 后胰腺炎发生。
尽管成功可视化率较低，但经 ERCP 导管使用 SpyGlass 探头的单操作员胰胆管镜检查是一种安全有效的操作。
