A Novel Approach to Repositioning Peritoneal Dialysis Catheters.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Peritoneal dialysis (PD) is a crucial kidney replacement therapy for patients with end-stage kidney disease. Despite its advantages over hemodialysis (HD), long-term success can be hindered by catheter dysfunction, which often necessitates revision. Currently, surgical treatment methods for PD catheter malfunction include fluoroscopy-guided procedures and laparoscopic or open surgery to salvage or replace the catheter. Here, we introduce the first novel, minimally invasive surgery for repositioning PD catheters. Methods: From November 2021 to May 2024, 8 patients with PD catheter dysfunction underwent this innovative procedure at the Department of Nephrology, Sichuan Provincial People's Hospital. Surgical Procedure: On the side of the original abdominal incision, blunt separation was used to find the PD catheter tunnel segment. The anterior rectus abdominal muscle sheath was incised, followed by separation of the deep polyester sleeve. The original catheter was exposed in the abdominal port or purse-string suture, and the intra-abdominal segment of the dialysis catheter was pulled out. Blunt cleaning around the periphery was performed to ensure that the PD catheter was smooth, and a rigid guidewire was placed through the intra-abdominal segment of the proximal end of the catheter of the first lateral hole. The intra-abdominal segment of the PD catheter was placed into the pelvis via the original catheter in the abdominal port. Clinical data were retrospectively collected, and patients were followed up for safety and efficacy assessment. Results: In a study involving 8 patients, no significant complications were observed, with an immediate imaging success rate of 100% and a clinical PD catheter reset success rate of 75%. The catheter remained patent until the end of the study, with a mean follow-up time of 17.25 ± 9.25 months. Conclusion: This new method for resetting dysfunctional PD catheters demonstrates technical feasibility, simplicity, cost-effectiveness, and safety. It has the potential to emerge as an alternative, particularly suitable for resource-limited settings.
