【Abstract】Objective Malfunction of the peritoneal dialysis (PD) tubes, especially displacement and occlusion of the tubes, are the main factors for non-infective PD-tube complications. We developed a new surgical technology that fixes the tubes on the inner surface of abdominal wall to prevent the occurrence of these situations. Method This was a retrospective study involving 278 end-stage renal disease patients treated in the Department of Nephrology, Renmin Hospital of Wuhan University. The conventional surgery of PD-tube placement was used in 123 patients (non-fixation group), and PD-tube placement surgery plus inner fixation of the tubes was performed in 155 patients (fixation group). PD-tube related complications including infections,

leakage, pain during dialysate infusion, tube displacement, and wrapped PD-tubes in the follow-up period of 6 months were compared between the two groups. Results In non-fixation group, the rate of tube displacement was 13.8%. In fixation group, the operation time was longer, no tube displacement occurred in the follow-up period of 6 months, and the early technical survival rate of PD-tubes became higher. Conclusion Inner fixation of the PD-tubes was effective to prevent the non-infective PD-tube complications, and the early technical survival rate of PD-tubes became higher.
