Continuous ambulatory peritonral dialysis (CAPD) is a well-established mode of renal replacement therapy in India. However, complications related to peritoneal dialysis catheter and other mechanical complications have hampered its success. There is paucity of data on the effect of mechanical complication on outcome of CAPD patients in India where initiation of renal replacement therapy is usually very late. This study was done to analyse the impact of initial catheter related and mechanical complications on outcome of CAPD patients.
This was a retrospective observational study from January 2012 to December 2019. All the patients had double cuffed silicon straight Tenckhoff catheter which was inserted by using an open surgical technique. Peritoneal dialysis was started after break in period of 12±2 days. Incidence of catheter related and mechanical complications were noted as exit site bleeding, bleeding from incision site, malposition and poor outflow, different hernias, pleuroperitoneal communication, scrotal swelling, bowel injury, intestinal obstruction and wound dehiscence. Patients with and without mechanical complications were categorized in to 2 groups. Peritonitis episodes in all patients were obtained from patients records and peritonitis rate between the 2 groups were compared. Catheter removal for resolution of mechanical complications were compared between 2 groups. Technique failure between patients with and without these complications were compared.
Conclusions
Peritonitis is common in patients with mechanical complications. Initial catheter related and mechanical complications may result in catheter removal and technique failure in such patients.
