The efficacy and safety of a novel method of peritoneal dialysis catheter insertion from the McBurney point

Abstract

Abstract Background Catheter dysfunction, especially omental wrapping, is a serious complication of peritoneal dialysis (PD). Although catheter implantation at a lower site was reported to prevent omental wrapping, this method could induce insufficient drainage of the PD solution and cause pain or a persistent desire to defecate, when the intraperitoneal catheter is of insufficient length or when its tip is in direct contact with the pelvic floor, respectively. The aim of this study was to assess the efficacy and safety of a novel PD catheter insertion method of approaching from the McBurney point, from the outer side of the abdomen. Methods This retrospective study included 23 patients with end-stage renal disease who were started on PD from January 2017 to July 2018 at Ashikaga Red Cross Hospital, Tochigi, Japan. Among them, 16 patients underwent a PD catheter insertion using a conventional method, whereas 7 patients underwent a novel method of approaching from the McBurney point. Infectious and mechanical complications were evaluated until August 2020. Results There were 18 men and 5 women, with a mean age of 63.1 ± 13.6 years. All patients were followed up postoperatively for a mean duration of 27.2 ± 13.4 months. No patient experienced omental wrapping, insufficient drainage of the PD solution, and pain or persistent desire to defecate in both groups. Both the incidence of infectious and mechanical complications (times per patient-year) were not statistically different between patients undergoing a conventional and a novel PD catheter insertion (0.18 vs. 0.24; p = 0.79 and 0.03 vs. 0.16; p = 0.16, respectively). Conclusions This novel method of PD catheter insertion from the McBurney point was safe, caused less discomfort, and was effective in preventing catheter dysfunction.
