Abstract
BACKGROUND This study aims to establish a simplified and effective animal model of catheter malfunction caused by omental wrapped using negative pressure suction. METHOD The peritoneal dialysis catheter outlet was linked to a negative-pressure (0-75mmHg) suction pump to intensify the negative pressure. Different negative pressures were tested for model construction in vitro. In vivo, a model of peritoneal catheter malfunction caused by omental wrapped was constructed in five beagles after catheter placement. Catheter drainage conditions and related complications were monitored before and after the model establishment. RESULTS In the vitro experiment, the overall success rate of constructed models was 90% (36/40). The total malfunction rate was higher in 62.5 mmHg (10/10) and 75 mmHg (10/10) than in 12.5 mmHg (8/10) and 37.5 mmHg (8/10). The outflow velocity of dialysate at 62.5 mmHg was significantly lower than that at 12.5 mmHg and 37.5 mmHg, without a statistically significant difference compared to 75 mmHg. In the in vivo experiment, catheter outflow velocity increased, and residual fluid volume decreased after omental wrapped (99.6 ± 6.7 ml/min vs. 32.6 ± 4.6 ml/min at initial five minutes, p < 0.0001; 69.2 ± 16.3 ml vs. 581.0 ± 109.4 ml, p < 0.001). And the outflow velocity was finally below 2 ml/min. No severe related complications (such as infection, organ damage, or bleeding) were observed through laparoscopic examination and dialysate tests seven days post-operation. CONCLUSION Utilizing negative pressure suction to increase negative pressure around catheter tip is a simple, safe, and effective method for establishing an animal model of omental wrapped leading to catheter malfunction.

Abstract
This report reviews the most common surgical interventions and complications of chronic peritoneal dialysis (PD) patients. Based on the current knowledge as well as our experience we detail the role of these surgical procedures. We supplement the reported knowledge in the field with our own experience in this area. The areas discussed include early complications such as surgical wound hemorrhage, bleeding from the catheter, intestinal perforation and urinary bladder perforation, dialysate leakage through the wound, as well as late complications including catheter kinking or occlusion, retention of fluid in the peritoneal recess, hernias and hydrothorax, and encapsulating peritoneal sclerosis. We also briefly cover the surgical aspects of exit-site infection and peritonitis. An understanding by nephrologists of the role for surgical intervention in PD patients will improve their care and outcomes.
