Abstract
The penetration of a peritoneal dialysis catheter into the intestinal cavity is a clinically rare complication. In the present retrospective clinical case series, 11 patients with uraemia who received continuous ambulatory peritoneal dialysis and attended hospital between 2019 and 2023 are described. The median patient age was 61.91 ± 11.33 years. All patients had previously experienced peritoneal dialysis-related peritonitis and were clinically cured by infusing sensitive antibiotics into the abdominal cavity. Colonoscopy was utilised to locate the penetrating catheter and close the perforation with a titanium clip once the catheter had been removed via an external approach. Following a 2-4-week fast, the perforations healed in all 11 patients. The present authors' experience illustrates that directly removing the catheter and clamping the perforation opening under the guidance of colonoscopy is simple to operate with few complications compared with traditional open surgery.
