“…The primary characteristics of omental wrapped of PDC are that the side holes and tip of PDC are encapsulated and obstructed by omentum [ 14–16 ]. The negative pressure may attract free omental tissue gathering around the PDC and even block catheter during the dialysis fluid discharge process [ 2 , 17 , 18 ].…”

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.

“…Another example was a 45-year-old man experiencing recurrent catheter obstruction accompanied by stomach pain, a laparoscopic examination found that the PD catheter was encircled by the sigmoid mesocolon. The catheter was eventually withdrawn, and the patient was switched to hemodialysis ( 3 ). Furthermore, the hemorrhagic corpus luteum was also discovered to be an uncommon cause of catheter obstruction, which was reabsorbed and the catheter resumed function following the next menstrual cycle ( 4 ).…”

Background Catheter malfunction is a common problem following the placement of a peritoneal dialysis (PD) catheter, and it is characterized by inadequate dialysate drainage, which can also limit infusion. Common causes include constipation, catheter migration, catheter kinking, omental wrapping, and fibrin obstruction. However, catheter obstruction by other intra-abdominal organs has been observed infrequently. Case Description We present two cases of female PD patients experiencing catheter dysfunction after catheter implantation. The first case involves a 28-year-old female who suffered from problematic drainage and infusion of dialysate 1 month after catheter insertion, evidenced by catheter displacement from the pelvis on abdominal X-ray. The second case concerns a 49-year-old female PD patient who also encountered a bidirectional catheter malfunction 40 days post-implantation. Conservative methods failed to restore the catheter function in both patients. Laparoscopic examination revealed fallopian tube, not the omentum, was tightly wrapped around the PD catheter in both cases. Finally, laparoscopic surgery with catheter fixation restored the catheter function, enabling continued continuous ambulatory peritoneal dialysis (CAPD) with favorable outcomes. Conclusions Our findings indicate that healthcare providers should consider fallopian tube wrapping as a potential cause of catheter dysfunction. Prompt consideration and utilization of laparoscopy with catheter fixation can play an important role in restoring catheter function and improving patient outcomes.
