A Rare Case of Catheter Obstruction in Peritoneal Dialysis Due to Entrapment of Oviductal Fimbriae.

Peritoneal dialysis is a renal replacement therapy modality used in patients with end-stage chronic kidney disease. Peritoneal dialysis catheters can present complications such as infections, leaks, catheter kinking, and mechanical obstruction. The obstruction can be caused by fibrin, adhesions, or entrapment of intraperitoneal organs; among them, the most frequent is the omentum. Entrapment of the fallopian tube fimbriae is an extremely rare complication, requiring early surgical attention. We present the case of a 65-year-old woman with chronic kidney disease on home peritoneal dialysis, who had a Tenckhoff catheter placed three months earlier. She presented to the Emergency Department with abdominal pain and decreased outflow from her catheter. An abdominal CT scan showed a catheter located in the right iliac fossa, mechanical obstruction was suspected, and open abdominal surgery was performed. During the surgery, the fimbriae of the right fallopian tube were found to be trapped in the Tenckhoff catheter. The fallopian tube was freed, and the catheter was adequately repositioned. The patient evolved satisfactorily; peritoneal dialysis was reestablished after two weeks, with no recurrence of long-term entrapment.
