以内镜黏膜下剥离术(ESD)为代表的超级微创非全层切除术广泛应用于早期消化道肿瘤的治疗,但治疗内镜、双钳道内镜价格高昂、普及率低,在一定程度上限制了超级微创手术在基层医院的推广。 作者团队研发了透明帽一体辅助通道,在猪模型上验证了其搭配常规内镜辅助实施ESD 的可行性,为下一步用于超级微创非全层切除术的临床实践奠定了基础。

Endoscopic submucosal dissection (ESD), as a representative of super minimally invasive non-full-thickness resection,has been widely used in the treatment of early gastrointestinal cancers.However, the high cost and low accessibility of therapeutic endoscopes and dual-channel endoscopes have limited the promotion of super minimally invasive surgery (SMIS) in primary hospitals. Our research team developed an additional capped unibody working channel and validated its feasibility for performing ESD with conventional diagnostic endoscope in porcine models, laying the foundation for future clinical applications.
