Entrapment of the appendix and the fallopian tube in peritoneal dialysis catheters in two children

Continuous ambulatory peritoneal dialysis (CAPD) has revolutionized the management of renal failure in children. However, CAPD catheter malfunction is not uncommon, the main complications being catheter-related infection and catheter-related obstruction. Herein the authors report both of the above complications, attributable to unique and previously unreported causes. One patient had appendicitis and peritonitis secondary to catheter entrapment of the appendix; the other had an obstructed catheter secondary to entrapment of the right fallopian tube within its lumen. To avoid potentially serious complications, early exploration of malfunctioning catheters is recommended.
