【摘要】 导管移位和大网膜包裹是导管故障的常见原因，通常会导致导管拔除或更换。传统的导管复位开放手术需要一条新的隧道，且导管复位手术后导管移位的发生率仍然与手术前一样高。拉线牵引固定式腹膜透析导管复位术（保留隧道复位术）在将导管复位的同时将导管固定于下腹壁，有效避免了导管再次移位，并且保留了原来的隧道，技术简单可靠，患者痛苦小，感染风险低。现将拉线牵引固定式腹膜透析导管复位术的标准操作流程总结如下，为广大临床工作者提供参考。更多还原

【Abstract】 Catheter migration and omental wrapping are common causes of catheter malfunction and often result in catheter removal or replacement. Traditional open surgical catheter repositioning requires creation of a new tunnel, and the incidence of catheter migration after repositioning remains as high as it was before surgery. The suture-traction fixed peritoneal dialysis catheter repositioning technique(tunnel-preserving repositioning technique) simultaneously repositions the catheter and secures it to the lower abdominal wall, effectively preventing recurrent catheter migration. In addition, it preserves the original tunnel. This technique is simple, reliable, causes minimal patient discomfort, and carries a low risk of infection. The standardized operative procedure for this suture-traction fixed peritoneal dialysis catheter repositioning technique is summarized below to provide a reference for clinical practitioners.更多还原
