Abstract titles should be brief and reflect the content of the abstract.
Recent advances in the biocompatibility of peritoneal dialysis (PD) solutions have reduced the incidence of peritoneal injury. Direct visualization of the PD catheter and peritoneal cavity enables early detection of catheter obstruction and structural abnormalities such as fibrin deposition or mesh-like fibrous formations. However, conventional diagnostic modalities cannot adequately assess the extent of peritoneal injury. At present, laparoscopy is the only method that provides direct visualization of the peritoneum, but it is highly invasive, requires anesthesia, and must be performed by experienced surgeons, limiting its feasibility for repeated evaluations. Thus, a noninvasive, repeatable technique to assess the PD catheter and peritoneal cavity is warranted.
We developed a disposable ultra-fine endoscope (outer diameter: 1.3 mm) that can be introduced through the tip of a PD catheter to visualize both the catheter lumen and the peritoneal cavity without the need for anesthesia or surgery. We conducted a prospective observational study in 14 stable PD patients (mean age, 57.2 ± 8.7 years; median PD duration, 91 months [49–133]; 10 males). The underlying kidney diseases were diabetic nephropathy (n=5), IgA nephropathy (n=3), nephrosclerosis (n=5), and chronic glomerulonephritis (n=1).
All procedures were performed with PD fluid in situ, without the use of anesthesia or prophylactic antibiotics. The device provided high-quality intraluminal and intraperitoneal images with no adverse events. Fibrin formation, the entire inner surface of the catheter, and the morphology of the visceral peritoneum under PD solution were clearly visualized in all cases.
This ultra-fine disposable endoscope enables direct and detailed visualization of the PD catheter and peritoneal cavity in a minimally invasive manner. Repeated examinations using this device may facilitate the identification of causes of catheter malfunction and allow longitudinal monitoring of peritoneal changes, including fibrin deposition, during PD therapy.
