研究目的:

1. 主要目的(以十二指肠为主):前瞻性评估十二指肠病灶行双镜联合治疗后的30天严重不良事件发生率及总体安全性; 2. 次要目的(十二指肠、胃、结直肠并行队列):评估双镜联合治疗的技术可行性与初步疗效,包括计划术式完成率、整块/切缘阴性(适用时)、围术期恢复指标(手术时间、出血量、住院天数等)及随访期残留/复发情况; 3. 探索性目的:收集手术相关的基础信息与过程指标,并探索其与并发症及转换/升级治疗的关系。  

Objectives of Study:

1. Primary objective (duodenum-focused): To prospectively evaluate the 30-day incidence of serious adverse events and the overall safety of dual-endoscopy treatment for duodenal lesions; 2. Secondary objectives (parallel duodenal, gastric, and colorectal cohorts): To assess the technical feasibility and preliminary efficacy of dual-endoscopy treatment, including the planned-procedure completion rate, en bloc resection and margin-negative resection (when applicable), perioperative recovery outcomes (such as procedure time, blood loss, and length of hospital stay), and residual/recurrent disease during follow-up; 3. Exploratory objective: To collect baseline and procedural variables related to the intervention and explore their associations with complications and conversion/escalation of treatment.

3.Lesions located in the stomach, duodenum, or colorectum.
4.Preoperative evaluation (endoscopic assessment with or without EUS/CT/MRI as appropriate) indicates localized disease without evidence of distant metastasis.
5.Considered fit to tolerate the planned procedure on anesthesia evaluation (ASA I–III or deemed feasible by the anesthesiology team).
6.Able to complete follow-up.
7.The subject or legally authorized representative voluntarily agrees to participate in the study and signs written informed consent.

排除标准:

1.明确或高度怀疑为进展期肿瘤,预计需要标准根治切除及/或系统性淋巴结清扫者;
2.影像学提示远处转移、腹膜播散或不可切除的多发病灶者;
3.经术前评估认为可采用常规内镜治疗(如 EMR/ESD/常规闭合)在不需要外科协作的情况下完成切除,且预期并发症风险可接受者;
4.严重心、肺、肝、肾功能不全或其他原因导致无法耐受麻醉/手术(如 ASA ≥IV 或麻醉科认为不宜);
5.凝血功能障碍不可纠正者;
6.抗凝/抗血小板治疗无法按规范停用且评估出血风险不可接受者;
7.活动性严重感染或全身状态不稳定者;
8.妊娠或哺乳期;
9.无法签署知情同意或无法配合研究流程/随访者;
10.研究者判断其他不适合者;

Exclusion criteria:

1.Definite or highly suspected advanced malignancy requiring standard radical resection and/or systematic lymph node dissection.
2.Imaging evidence of distant metastasis, peritoneal dissemination, or multiple unresectable lesions.
3.Judged preoperatively to be amenable to conventional endoscopic treatment alone (e.g., EMR/ESD/conventional closure) without surgical collaboration, with acceptable anticipated complication risk.
4.Severe cardiac, pulmonary, hepatic, or renal dysfunction, or other conditions rendering the patient unable to tolerate anesthesia/surgery (e.g., ASA ≥ IV or deemed unsuitable by the anesthesiology team).
5.Uncorrectable coagulation dysfunction.
6.Inability to discontinue anticoagulant/antiplatelet therapy according to standard requirements, with unacceptable bleeding risk on assessment.
7.Active severe infection or unstable general condition.
8.Pregnancy or lactation.
9.Inability to provide informed consent or to comply with study procedures/follow-up.
10.Any other condition judged by the investigators to make the patient unsuitable for participation.
