A decrease in the peritonitis rate and the incidence of catheter exit-site/tunnel (E/T) infection are the most important factors affecting the permanent peritoneal catheter in continuous ambulatory peritoneal dialysis (CAPD) patients. Moncrief et al. have introduced a novel methodology (two phases) for peritoneal catheter placement (7.8). The most relevant characteristic is that the external portion remains buried on the subcutaneous tissue (sterile environment) during the healing process. After four to six weeks, the catheter is brought out through a small incision (0.5 cm) distal 2 cm from the subcutaneous cuff, and peritoneal dialysis may be initiated. The data available, presented by Moncrief et al., show a lower incidence of peritonitis rate and E/T infection with this implantation technique, when compared with a classic technique. The aim of this study is to learn if the placement of a peritoneal catheter with Moncrief's methodology decreases the incidence of complications related to peritoneal catheters. We treated 29 patients (group C) with the conventional procedure and 25 patients (group M) with the Moncrief technique. Follow-up was similar for both groups (C = 12.2 +/- 7.9 months vs M = 11.1 +/- 6.1 months, NS). The time buried was 3.23 +/- 0.9 weeks (2-5). Eleven patients completed four weeks with the catheter buried subcutaneously (group M-4). The incidence of E/T infection was similar for groups C and M, and lower in group M-4 (p < 0.05). The number of catheters free of infection was less in group C (31%) than in group M (46%) and M-4 (67%) (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
