研究目的:

对比一次性连发结扎夹与非连发结扎夹在肾手术关键环节(肾蒂血管处理、淋巴结清扫)的操作效率与安全性差异。 系统评估两种结扎夹对术后恢复指标(手术总时长、术中出血量、术后引流量、住院天数及并发症发生率)的影响。 结合临床场景(机器人辅助手术、复杂血管解剖、医疗资源条件)分析连发结扎夹的优势适用范围及局限性。 探索性评估两种结扎夹操作对患者术后微小残留病灶与肿瘤学预后的潜在影响,通过循环肿瘤DNA进行动态监测。  

Objectives of Study:

Compare the operational efficiency and safety differences between the one-time consecutive ligation clips and the non-consecutive ligation clips in the key steps of kidney surgery (renal pedicle vessel handling and lymph node dissection). Systematically evaluate the effects of the two types of ligation clips on postoperative recovery indicators (total operation time, intraoperative blood loss, postoperative drainage volume, hospital stay, and complication rate). Analyze the advantages, applicable scope, and limitations of the consecutive ligation clips based on clinical scenarios (robot-assisted surgery, complex vascular anatomy, and medical resource conditions). Exploratory assessment of the potential impact of the operation of the two ligation clips on postoperative microscopic residual lesions and oncological prognosis, through dynamic monitoring of circulating tumor DNA.

Inclusion criteria

排除标准:

手术相关禁忌:既往有腹部大手术史导致严重腹腔粘连,或存在肾门区血管严重变异(如多支肾动脉直径>10mm 且走行复杂);拟联合其他脏器切除(如肾上腺、脾脏)。 患者自身因素:存在严重凝血功能障碍(如血友病、长期服用抗凝药且无法停药)或全身性感染(体温>38.5℃,白细胞>15×10⁹/L);对结扎夹材料过敏(如钛合金、聚乙醇酸类聚合物过敏史);合并远处转移(如肺、骨转移)或严重基础疾病(如终末期肾病、肝硬化失代偿期),预期生存期<1 年。 研究干扰因素:术中需联合其他止血器械(如血管缝合器)处理主要血管。 知情同意:患者拒绝使用结扎夹或中途退出研究,无法完成完整随访。

Exclusion criteria:

Surgical contraindications: Previous history of major abdominal surgery resulting in severe abdominal adhesions, or severe variations in renal hilum vessels (such as multiple renal arteries with diameters > 10mm and complex course); planned to combine other organ resections (such as adrenal gland, spleen). Patient-related factors: Severe coagulation dysfunction (such as hemophilia, long-term use of anticoagulants and inability to discontinue them), or systemic infection (body temperature > 38.5℃, white blood cell count > 15×10⁹/L); allergy to ligature clip materials (such as titanium alloy, polyethylene acid polymer allergy history); distant metastasis (such as lung, bone metastasis) or severe underlying diseases (such as end-stage kidney disease, decompensated liver cirrhosis), with expected survival < 1 year.

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:

数据采集:采用电子病例系统记录基线资料(年龄、BMI、肿瘤分期等)及术中、术后数据,内容包括患者基本信息、手术指标、恢复指标、并发症情况及随访结果。由两名研究者双盲录入数据库,进行逻辑核查与一致性检验,对缺失或异常数据及时溯源补充。 数据管理:原始数据(手术记录、随访表单、影像学报告)纸质版归档保存,电子数据库由独立统计人员加密存储,仅授权人员可访问。

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

Data collection: Baseline data (such as age, BMI, tumor stage, etc.) and intraoperative and postoperative data were recorded using an electronic case system. The content included patient basic information, surgical indicators, recovery indicators, complication situations, and follow-up results. Two researchers entered the data into the database in a double-blind manner, conducting logical verification and consistency checks. Missing or abnormal data were promptly traced and supplemented. Data management: The original data (surgical records, follow-up forms, imaging reports) were archived and preserved in paper form. The electronic database was encrypted and stored by independent statisticians, and could only be accessed by authorized personnel.
