#3122 30-DAY COMPLICATIONS IN PERITONEAL DIALYSIS CATHETERS INSERTED PERCUTANEOUSLY VERSUS SURGICALLY IN A SECOND LEVEL HOSPITAL IN MERIDA, YUCATAN, MEXICO

Abstract

Abstract Background and Aims Peritoneal dialysis (PD) catheter insertion technique has an impact on the health outcomes and technical success in PD. The percutaneous technique allows for a bedside, minimally invasive and faster insertion without the need of using an operating room and general anesthesia. In 2021, Agarwal et. al reported that percutaneous insertion was associated with a 64% relative risk reduction (RRR) of early exit site infection and a 48% RRR of early peritonitis with no difference in terms of mechanical complications compared to the surgical technique [1]. The aim of our study was to describe the frequency of mechanical and infectious complications within the first 30 days of PD catheter insertion between the percutaneous and surgical technique. Method We conducted a descriptive and prospective study in our Hospital from January 1st to December 31st, 2022. Patients who were candidates for renal replacement therapy with PD and who had no previous history of abdominal surgery or only minor abdominal surgery, underwent percutaneous insertion of PD catheter by a nephrologist with a bedside blind technique, whereas patients with previous abdominal surgery underwent surgical insertion with a mini laparotomy. Informed consent and preoperative blood tests were obtained before the procedure in both techniques. Patient preparation for the percutaneous insertion included fasting the night before, colonic enema and the placement of a urinary catheter, patients received antimicrobial prophylaxis as well as analgesia and light sedation. Mechanical and infectious complications within the first 30 days after insertion of double cuff Tenckhoff catheters were registered. Results During the study period, 155 PD catheter insertions took place in our hospital, the majority of insertions were surgical (53.5% versus 46.4%) and happened in women (60.6%). The mean age of the population was 51.5 years and 70.3% of the participants were diabetic. Exit-site infection was significantly more frequent in the surgically placed PD catheters (10% versus 1%, p = 0.02), there was a tendency for more mechanical dysfunction in the surgical technique versus the percutaneous technique (14.4% versus 5.5%, p = 0.07) and transfer to hemodialysis was more frequent in the surgical insertion group (10.8% versus 1.3%, p = 0.01). There was no difference between peritonitis in both groups and the frequency of uncomplicated PD catheters (catheter survival without any complication) was similar in both techniques. Conclusion Bedside PD catheter insertion by the nephrologist using a percutaneous technique can be an easy, timely, safe and adequate procedure with comparable success to the surgical insertion. It may have the advantage of more efficient control of infectious and mechanical complications and what is more, this approach could reduce the cost of kidney failure treatment as it allows for the use of minimal material and human resources.
