HS-46 Evaluating Omentopexy in Peritoneal Dialysis Catheter Placement: Outcomes Among South Carolinian Patients

End-stage renal disease (ESRD) is a major healthcare challenge, particularly in South Carolina, where kidney disease prevalence remains high. Peritoneal dialysis (PD) is a commonly used renal replacement therapy, but its success depends on the proper function of the peritoneal dialysis catheter, which is susceptible to various complications, including malfunction. The best surgical approach to reduce catheter-related issues remains uncertain. Omentopexy, a technique that involves securing the omentum to the anterior abdominal wall, has been proposed as a method to enhance catheter performance; however, limited research has explored its effectiveness, especially within South Carolinian patients. This retrospective cohort study evaluates outcomes in 400 patients who underwent initial peritoneal catheter placement at Greenville Memorial Hospital between January 1, 2018, and May 15, 2024. The goal is to assess whether omentopexy is associated with improved catheter function. The primary outcome measure is the rate of catheter malfunction in patients who received omentopexy compared to those who did not. Secondary outcomes include hospital readmission rates, reasons for catheter removal, and a detailed analysis of the demographic and clinical characteristics of Greenville Memorial’s PD population. To analyze the data, statistical methods such as logistic regression, T tests, and ANOVA will be applied. Additionally, we will examine patient comorbidities and prior abdominal surgeries to determine their impact on catheter function. By comparing our primary (reoperation for catheter malfunction) and secondary outcomes (readmission within 30 days and catheter removal) between patients who underwent omentopexy and those who did not, we hope to provide more definitive evidence on the association of omentopexy with favorable patient outcomes. The findings may support the adoption of omentopexy as a standard surgical approach, identify patients who are most likely to benefit, and contribute to more personalized treatment strategies for individuals with specific health conditions in South Carolina.
