随机方法(请说明由何人用什么方法产生随机序列):

由于放大内镜在对焦观察时需要更接近病变,存在对病变部位造成轻微损伤的可能,因此纳入的患者首先由一名内镜医师独立进行WLI检查,随后由另一名内镜医师独立进行ME-NBI检查,以避免两种不同内镜方法对彼此检查结果造成影响。 将纳入的患者分为两组,一组由甲内镜医师先进行WLI检查,随后由乙内镜医师进行ME-NBI检查,另一组由乙内镜医师先进行WLI检查,随后由甲内镜医师进行ME-NBI检查。本研究采用随机数字表法进行随机分组,使用Microsoft Office Excel生成随机数字表格,按纳入先后顺序将患者随机分配至各组(图1)。研究过程中确保两名内镜医生不了解患者既往内镜检查结果及病理结果等临床资料。研究过程中将进行纸质版记录,并保留原始研究文件。 对于内镜目的为切除治疗的1型gNET患者将首先由不知患者病情的内镜医师完成内镜检查,在记录两种方法的内镜结果后,由研究助理将拟切除病变的具体信息(前次诊断gNET时描述的部位)告知内镜医师,完成完整切除手术后将病变标本送病理科完善病理诊断。

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

Since magnifying endoscopy needs to be closer to the lesion in focus observation, which may cause minor damage to the lesion site, the included patients were first independently examined by an endoscopist for WLI and then independently examined by another endoscopist for ME-NBI, so as to avoid the influence of two different endoscopic methods on each other's examination results. The included patients were divided into two groups: one group was performed WLI examination first by an endoscopist and then ME-NBI examination by an endoscopist B; the other group was performed WLI examination first by an endoscopist B and then ME-NBI examination by an endoscopist A. In this study, the random number table method was adopted for randomization. Microsoft Office Excel was used to generate a random number table, and patients were randomly assigned to each group according to the order of inclusion (Figure 1). During the study, it was ensured that the two endoscopists did not know the clinical data such as the previous endoscopy results and pathological results of the patients. Paper records will be made during the research process and original research documents will be retained. For patients with type 1 gNET whose endoscopic purpose is resection, endoscopic examination will first be performed by an endoscopist who does not know the patient's condition. After recording the endoscopic results of the two methods, the research assistant will inform the endoscopist of the specific information of the lesion to be resected (the site described in the previous diagnosis of gNET), and the lesion specimen will be sent to the pathology department for pathological diagnosis after complete resection.
