Abstract: 【Abstract】Objective To improve the method of peritoneal dialysis catheterization in children in order to reduce the postoperative complications and to increase the efficiency of peritoneal dialysis (PD). Methods The children undergoing PD catheterization in the Department of Pediatric Surgery, Peking University First Hospital from January 2015 to December 2018 were retrospectively reviewed. Results A total of 51 cases were enrolled in this study. According to the method of catheterization, they were divided into unresected omentum group (n=23) and partial resected omentum group (n=28). In unresected omentum group, the catheter was inserted into abdominal cavity through a distance of abdominal wall in right rectus abdominis; postoperative occlusion of the tube was found in 5 cases (21.74%). In partial resected omentum group, the catheters were placed using the same method and the omentum was partially removed; no postoperative occlusion of the tube was found and no secondary operation was required. The difference in catheter occlusion was statistically significant between the two groups (χ2=6.749,P=0.009). No postoperative infection occurred in both groups. Conclusion The PD catheter inserted into abdominal cavity through a distance of abdominal wall in right rectus abdominis and partial removal of omentum can significantly reduce the postoperative complications and the requirement for secondary operation, facilitating the PD management in children.
