研究目的:

本研究旨在深入剖析内镜粘膜下剥离术(ESD)在临床应用中面临的瓶颈问题,通过研发无创集成式气封-集液装置,有效解决低位结直肠ESD手术中CO2气体溢出、粪水污染、手术视野不佳及出血等难题,提高ESD手术的操作精准度与安全性,降低手术并发症发生率,缩短手术时间。  

Objectives of Study:

This study aims to thoroughly analyze the bottlenecks in the clinical application of endoscopic submucosal dissection (ESD). By developing a non-invasive integrated air seal-fluid collection device, we intend to effectively solve problems such as CO? gas leakage, fecal contamination, poor surgical visualization, and bleeding during low colorectal ESD, thereby improving the accuracy and safety of ESD, reducing the incidence of postoperative complications, and shortening operation time.

随机方法(请说明由何人用什么方法产生随机序列):

采用随机数表法进行随机分组。由不参与患者招募及分组工作的独立研究者,使用标准随机数表产生随机序列。符合纳入排除标准的患者,根据该随机序列按 1:1 比例随机分配至观察组与对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Random number table method was used for randomization. The random sequence was generated by an independent researcher who was not involved in patient recruitment and grouping using a standard random number table. Eligible patients were randomly assigned to the Observation Group and the Control Group at a 1:1 ratio according to the random sequence.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

不实施盲法。由于术中需明确使用或不使用肛周无创辅助装置,术者、护理人员及受试者无法实施盲法;结局指标(手术时间、出血量等)为客观临床指标,评估过程不受主观因素显著影响。

Blinding:

No blinding was implemented. Blinding was not feasible for surgeons, nursing staff, or participants because the use of the non-invasive perianal auxiliary device was explicitly determined during the operation. Outcome measures (e.g., operation time, blood loss) were objective clinical indicators, and the assessment process was not significantly influenced by subjective factors.
