Innovative management of peritoneal catheter malfunction caused by omental wrapping: exploration the modified low-temperature plasma ablation blade in vivo and in vitro

Omental wrapping is a common complication of peritoneal dialysis, which manifests as catheter malfunction causing early termination of peritoneal dialysis. This study investigates the efficacy and safety of a Modified Low-Temperature Plasma Ablation (MLTPA) blade in treating omental-wrapped catheter malfunction. experiments using the MLTPA blade at the 5th power level were conducted to ablate omental tissues and catheters, evaluating ablation effects and potential catheter damage. , nine beagles were modeled for catheter malfunction due to omental wrapping, randomized into MLTPA blade ( = 5) and the Gastroscopic Biopsy Forceps (GBF) groups ( = 4). Dialysate outflow velocity, dialysate residual volume, and complications were recorded. experiments showed that the MLTPA blade effectively ablated omental tissue without damaging the catheter at the 5th power level. , the MLTPA blade group achieved a 100% (5/5) catheter recanalization success rate, significantly increasing catheter outflow velocity (111.4 ± 5.1 ml vs. 3.0 ± 1.0 ml,
