Surgical aspects of continuous ambulatory peritoneal dialysis--3 years experience.
Since January 1979, 122 patients (mean age 38.5 years, range 5-72 years) with chronic renal failure have been treated with continuous ambulatory peritoneal dialysis (CAPD). Peritoneal access was achieved by inserting silicone rubber Tenckhoff peritoneal dialysis catheters (Quinton, Seattle, Washington) by an open (76 per cent) or closed technique. Actuarial analysis showed a patient survival of 98 and 94 per cent and a success rate of 88 and 64 per cent at 1 and 2 years, respectively. Currently, 74 patients are using CAPD and 8 have been treated for 30-36 months. Thirty-five patients (29 per cent) required two or more peritoneal catheters and 69 per cent of these patients are still on CAPD. Catheter-related peritonitis was the most frequent complication (233 separate episodes in 94 patients) and necessitated catheter removal in 16 per cent of episodes, although 37 per cent of patients from whom catheters were removed because of peritonitis later resumed CAPD. Extravasation of dialysate from the peritoneal cavity (31 episodes) and catheter obstruction (31 episodes) required surgical replacement of catheters in 8 and 23 cases, respectively. Twenty patients (16 per cent) developed 24 abdominal hernias, only one of which caused failure of CAPD. Infective and mechanical complications of CAPD frequently require surgical intervention but only occasionally result in failure of the technique, and even multiple catheter replacements are compatible with successful long term CAPD.
