随机方法(请说明由何人用什么方法产生随机序列):

本研究采用多中心、前瞻性随机对照设计。所有符合入选标准的病例,将由电脑随机选择分组,按照1:1的比例随机分配至对照组(传统多孔腹腔镜远端胃切除术,MPLDG)和研究组(移动式双悬吊技术下单孔腹腔镜远端胃切除术,SPLDG-MDST)。

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

This study adopts a multicenter, prospective randomized controlled design. All eligible cases will be randomly assigned by computer-generated randomization in a 1:1 ratio to either the control group (Multiport Laparoscopic Distal Gastrectomy, MPLDG) or the study group (Single-Port Laparoscopic Distal Gastrectomy with Mobile Dual Suspension Technique, SPLDG-MDST).

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

一、病例记录表(CRF) 本研究采用纸质版病例报告表进行数据采集。CRF根据研究方案设计,涵盖患者基线资料、术中指标(手术时间、出血量等)、术后恢复指标(首次离床时间、排气时间、排便时间、住院时间等)、并发症(Clavien-Dindo分级)、实验室检查、影像学评估、病理结果、随访数据等。CRF由经培训的研究者填写,数据录入后进行双人核对,确保数据准确性和完整性。所有CRF资料保存于研究中心的专用文件柜中,由专人管理,保存期限为研究结束后10年。 二、电子采集和管理系统(EDC) 本研究采用中国临床试验注册中心官方推荐的ResMan(Research Manager)平台进行电子数据采集与管理(网址:http://www.medresman.org.cn)。研究者在CRF填写完成后,通过ResMan平台进行双人独立录入、交叉核对。系统设置逻辑核查、范围核查和一致性核查功能,可自动识别异常数据并发出质疑。研究者对质疑进行解答修正后,由数据管理员进行审核锁定。系统支持数据导出、统计分析及备份功能,确保数据真实、完整、可追溯。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

I. Case Report Form (CRF) This study uses paper-based Case Report Forms for data collection. The CRF is designed in accordance with the study protocol and covers patient baseline data, intraoperative indicators (e.g., operative time, blood loss), postoperative recovery indicators (e.g., time to first ambulation, time to flatus, time to defecation, length of hospital stay), complications (Clavien-Dindo classification), laboratory tests, imaging assessments, pathological results, and follow-up data. The CRF is completed by trained investigators, and after data entry, double verification is performed to ensure data accuracy and completeness. All CRF documents are stored in dedicated filing cabinets at the study center, managed by designated personnel, and retained for 10 years after the completion of the study. II. Electronic Data Capture and Management System (EDC) This study uses the ResMan (Research Manager) platform (website: http://www.medresman.org.cn), officially recommended by the Chinese Clinical Trial Registry, for electronic data capture and management. After the CRF is completed, investigators perform dual independent data entry and cross-verification on the ResMan platform. The system is equipped with logic checks, range checks, and consistency checks, enabling automatic identification of anomalous data and generation of queries. After investigators address and correct the queries, the data administrator reviews and locks the data. The system supports data export, statistical analysis, and backup functions, ensuring that the data are authentic, complete, and traceable.
