研究目的:

本研究拟通过前瞻性、多中心、开放标签、随机对照、非劣效性临床试验,系统比较双重套扎黏膜下切除术(ESMR-DL)与内镜黏膜下剥离术(ESD)在治疗直径 ≤10 mm 直肠神经内分泌瘤(R-NETs)中的有效性与安全性差异。主要目标为比较两组 R0 切除率,验证 ESMR-DL 在 R0 切除率方面是否不劣于 ESD。次要目标为比较两组手术效率、安全性、医疗成本及病理切缘深度,明确 ESMR-DL 是否具备替代 ESD 的临床可行性与推广价值,从而为低风险 R-NETs 提供更安全、高效、经济的治疗策略。  

Objectives of Study:

This prospective, multicenter, open-label, randomized controlled non-inferiority trial aims to compare the efficacy and safety of double band ligation-assisted endoscopic submucosal resection (ESMR-DL) with endoscopic submucosal dissection (ESD) for rectal neuroendocrine tumors (R-NETs) measuring 10 mm or less. The primary objective is to compare the R0 resection rate between the two groups and to determine whether ESMR-DL is non-inferior to ESD in achieving R0 resection. Secondary objectives include comparisons of procedural efficiency, safety, medical costs, and pathological vertical margin depth, in order to evaluate whether ESMR-DL is a clinically feasible and generalizable alternative to ESD for low-risk R-NETs.

Sample size:

干预措施:

内镜下定位 R-NETs 病灶;病灶基底部黏膜下注射含少量靛胭脂和稀释肾上腺素的甘油果糖复合物或生理盐水,使病灶及周围正常黏膜充分抬举;安装多连发套扎器后对准病灶中心进行负压吸引并释放第一枚套扎环;随后将透明帽沿已形成的假息肉向基底侧压迫,再次负压吸引更深层黏膜下组织并释放第二枚套扎环;最后将高频电圈套器定位于第二个套扎环下方,经确认未卷入固有肌层后使用高频电凝电切混合电流完整切除病灶,并常规使用内镜金属止血夹预防性闭合创面。使用器械包括单通道内窥镜(CF-H290I,日本奥林巴斯)、新月形圈套器(SD-221 L-25,日本奥林巴斯)及套扎器(MBL-U-10,爱尔兰库克)。

干预措施代码:

Intervention:

The procedure includes endoscopic localization of the R-NET lesion; submucosal injection at the base of the lesion using glycerol fructose solution or normal saline containing a small amount of indigo carmine and diluted epinephrine to lift the lesion and surrounding normal mucosa; placement of a multiband ligation device, negative-pressure suction of the lesion into the transparent cap, and deployment of the first band; downward compression of the cap along the formed pseudopolyp toward the basal side, followed by a second negative-pressure suction to capture deeper submucosal tissue and deployment of the second band; and final placement of a high-frequency snare below the second band to resect the lesion en bloc after confirming that the muscularis propria is not entrapped. The wound will routinely be closed prophylactically with endoscopic clips. Devices include a single-channel colonoscope (CF-H290I, Olympus, Japan), crescent snare (SD-221 L-25, Olympus, Japan), and ligation device (MBL-U-10, Cook, Ireland).

Intervention code:

组别:

ESD 组

样本量:

142

Group:

ESD group

Sample size:

干预措施:

白光及染色内镜下观察肿瘤边界;于病灶边缘外侧 3-5 mm 正常黏膜处进行点状电凝标记;进行黏膜下注射以分离病灶与固有肌层;使用专用剥离电刀沿标记外侧进行环周预切开;在透明帽辅助下逐层进行黏膜下剥离,剥离经过病灶下方时紧贴固有肌层表面操作以保证完整切除;病灶整块剥离后处理裸露血管,并视情况使用止血夹缩小创面。参与 ESD 操作的内镜医师应具备丰富结直肠 ESD 独立操作经验,方案规定由完成过 100 例以上 ESD 的资深医师主刀。使用器械包括单通道内窥镜(CF-H290I,日本奥林巴斯),剥离电刀可采用 Dual-knife、IT-knife、Flush-knife 等。

干预措施代码:

Intervention:

The procedure includes careful observation of tumor margins under white-light and chromoendoscopy; marking 3-5 mm outside the lesion margin on normal mucosa; submucosal injection to separate the lesion from the muscularis propria; circumferential mucosal incision along the outside of the marks using a dedicated endoscopic dissection knife; layer-by-layer submucosal dissection under direct vision with cap assistance, with dissection close to the muscularis propria underneath the lesion to ensure complete resection; and treatment of exposed vessels after en bloc resection, with wound closure using endoscopic clips when appropriate. ESD will be performed by experienced endoscopists with independent colorectal ESD experience; the protocol specifies that senior endoscopists who have completed more than 100 ESD procedures should perform the operation. Devices include a single-channel colonoscope (CF-H290I, Olympus, Japan), and dissection knives such as DualKnife, ITKnife, or FlushKnife.

采用 EDC 系统集成的中央随机化模块进行随机分配。各分中心研究协调员在确认受试者符合全部纳入/排除标准后,将基线资料录入系统,系统按 1:1 比例实时生成随机分配号及分组结果。随机化按研究中心和肿瘤大小进行分层。

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

Randomization will be performed through a central randomization module integrated in the electronic data capture (EDC) system. After eligibility is confirmed at each participating center, the clinical research coordinator will enter baseline data into the system, and the system will generate the randomization number and treatment allocation in real time in a 1:1 ratio. Randomization will be stratified by study center and tumor size.
