Background: Chronic peritoneal dialysis is a safe method for the treatment of end-stage renal failure. Worldwide, patients on chronic peritoneal dialysis constititute approximately 15% of the total number of patients on dialysis. In Iran, very few people have access to chronic peritoneal dialysis, which is targeted by the Ministry of Health. This lack of access is primarily due to the high occurrence of mechanical complications. Improving catheterization procedures is an important way to extend the use of peritoneal dialysis in Iran. Thus, a prospective study was implemented to evaluate the outcome of a new laparoscopic technique for the insertion of peritoneal dialysis catheters under local anesthesia.
Methods: A total of 115 catheters (two-cuff, swan-necked, coiled) were inserted into the peritoneal cavity of 109 patients with end-stage chronic renal failure during a 16-month period. The method of insertion was a two-port laparoscopic technique with local anesthesia and sedation. All patients were followed for 12 to 28 months. We prospectively evaluated mechanical and infectious complications and survival rates of the catheters.
Results: The average age of the patients was 51.5 years (range: 15-84 years); 54.8% of these patients were female. The overall one-year and two-year catheter survival rates using this approach were 88% and 73%, respectively. Event-free catheter survival was 35%. The most common infectious and mechanical complications were peritonitis in 52 cases (45.2%) and temporary dialysate leakage in 10 cases (8.7%) respectively.
Conclusion: Laparoscopic insertion of peritoneal dialysis catheter with local anesthesia is a safe and simple procedure, giving reasonable rates of catheter survival and complications.
