摘要
随着影像学技术的进步以及经口胆胰管镜直视下诊断技术的普及，胆胰管系统内的息肉样病变发现率逐步升高。这些病变存在一定恶变风险，患者往往陷入外科手术切除过度治疗与随访观察错过最佳手术时机的两难境地。因此，2022年9月作者团队与南京医学科技股份有限公司合作研发了经口胆胰管镜直视下使用的电凝电切圈套器，并在体外模仿胆胰管内液体环境进行了体外实验证实其有效性与可行性，为下一步经口胆胰管镜直视下超级微创圈套电凝切除术的临床实践奠定了基础。
Abstract
With the improvement and popularization of radiological and peroral biliary-pancreaticoscopy techniques, more and more polypoid lesions in the biliary-pancreatic duct system, including pancreatic duct, common bile duct (CBD), common hepatic duct (CHD) and cholecyst, were found. These patients with polypoid lesions in the biliary-pancreatic duct system often faced a dilemma. Surgical treatment for those polypoid lesions was accompanied by relatively large trauma; on the other hand, follow-up observation comes with the risk of progression of lesions. Therefore, our team developed a kind of snare with the electrocision function, which can pass through the working tunnel of peroral biliary-pancreaticoscopy. In this study, we attempted the peroral biliary-pancreaticoscopy super minimally invasive electrocision using snare in the vitro model, and confirmed the effectiveness and feasibility of this technique.
