Catheter malfunction—migration, inflow/outflow failure, and early technical failure—remains a key barrier to sustained peritoneal dialysis (PD). Laparoscopic placement improves visualization yet does not fully prevent malposition. We developed a device-free, easily reproducible dual-fixation modification that combines peritoneal anchoring with direct suturing of the first cuff to the anterior rectus sheath, aiming to enhance tip stability without special equipment or advanced maneuvers.
We conducted a single-center retrospective analysis of 82 consecutive PD catheter implantations (August 2020–September 2024). Patients were assigned to a conventional method (n=68) or the modified dual-fixation method (n=14). Outcomes included operative time, need for reinsertion or abdominal wall fixation, catheter migration/malposition, and early complications. Categorical variables were compared with χ²/Fisher’s exact tests and continuous variables with the Mann–Whitney U test; p<0.05 was considered significant.
Baseline characteristics were comparable. Laparoscopic assistance was used more often in the modified group (85.7% vs. 44.1%, p=0.007). Operative time was shorter with the modified method: median 92 [83–106] min vs. 99 [85–116] min; p=0.005. No patient in the modified group required catheter reinsertion, additional abdominal wall fixation, or reoperation. There were no migration/malposition events observed after the modified procedure during the recorded follow-up. Catheter removal occurred less frequently in the modified group (7.1% vs. 26.5%), without statistical significance (p=0.171). Exit-site relocation was uncommon and similar between groups (ns). No suture-related complications were recorded in the modified cohort.
This dual-fixation approach—peritoneal anchoring plus anterior rectus sheath cuff suturing—provides a simple, equipment-free, and reproducible modification to standard PD catheter implantation. It reduces operative time and showed no need for secondary fixation or reinsertion in our series, with a favorable (though not always statistically significant) profile for catheter stability. Larger, multicenter studies with longer follow-up are warranted to confirm durability and generalizability.
