Peritoneal dialysis catheter dysfunction is one of the important complications of peritoneal dialysis, among which omental wrapping of the catheter is a major cause of catheter dysfunction, posing significant challenges to clinicians and patients. Accurately determining the presence of catheter wrapping is crucial for guiding diagnosis and treatment.
This study retrospectively analyzed 32 patients with peritoneal dialysis drainage disorders. The duration of peritoneal dialysis catheter placement ranged from 5 days to 6 years, and all patients underwent laparoscopic catheterization. Among them, 24 cases were accompanied by slow inflow of peritoneal dialysis fluid, and all patients showed no improvement in drainage disorders after enema and abdominal massage. A total of 30 patients underwent peritoneal dialysis catheter angiography: the patients lay flat, and 50 ml of a mixed solution of iohexol and 0.9% sodium chloride was slowly injected through the peritoneal dialysis catheter under X-ray. The position of the catheter tip and the diffusion of contrast agent in the abdominal cavity were observed via video. If the contrast agent diffused rapidly, omental wrapping of the catheter was not supported (Figure A); if the contrast agent accumulated around the catheter tip with poor diffusion, omental wrapping of the catheter was considered (Figure B).
Of the 30 patients, 27 showed omental wrapping of the catheter (including 12 cases with the catheter located in the true pelvis and 15 cases with catheter displacement), and 3 cases were suspicious. Among the patients with angiographic findings suggesting omental wrapping, 25 underwent laparoscopic exploration, and 23 were confirmed to have omental wrapping of the catheter (Figure C). The positive diagnostic rate of peritoneal dialysis catheter angiography for omental wrapping was 85.2%.
Peritoneal dialysis catheter angiography is an effective method for determining omental wrapping of the peritoneal dialysis catheter.
