Abstract

♦ Background: Outflow obstruction, a common complication in patients with peritoneal dialysis (PD), usually results in unnecessary catheter removal or replacement. This study describes a modified simple method of anchoring a PD catheter on the anterior peritoneal wall without using a laparoscopic system (peritoneal wall anchor technique, PWAT). ♦ Methods: We performed a retrospective cohort study of consecutive PD catheter insertions, and compared the catheter survival rate between the traditional method and the modified simple PWAT. The traditional method was used in 54 cases and the modified simple PWAT was used in 17 cases. The primary endpoint was the occurrence of surgical catheter repair because of outflow obstruction by day 365. The secondary endpoint was the occurrence of catheter migration with obstruction requiring any interventions, including the alpha-replacement method by day 365. Catheter survival was analyzed by Kaplan-Meier survival curves. ♦ Results: Migration-free catheter survival was significantly (p = 0.02) higher in the PWAT group (100%, 17/17) than in the traditional group (72.2%, 39/54). Catheter survival without surgical repair or cessation of PD was also significantly (p = 0.04) higher in the PWAT group (100%, 17/17) than in the traditional group (77.8%, 42/54). Similarly, migration-free and surgery-free catheter survival rates in cases with a straight-type catheter in the PWAT group were significantly higher than those in cases with a straight-type catheter in the traditional group. ♦ Conclusions: Our results suggest that the modified simple PWAT provides a better catheter survival rate than the traditional method by preventing catheter migration with obstruction in PD.
