腹膜透析カテーテル灌流障害に対しReduced port surgeryにて解除を行った1例

概要

A 17-year-old man received continuous ambulatory peritoneal dialysis (CAPD) catheter implantation and had started peritoneal dialysis. Perfusion failure of peritoneal dialysis catheter occurred one month after the catheter implantation. Transcatheter contrast examination revealed catheter obstruction about 4-5 cm from the catheter tip. We performed reduced port surgery to remove the obstruction. Laparoscopy revealed that the omentum was adhered to the abdominal wall and wrapped the catheter. We diagnosed the cause of catheter malfunction as omentum wrapping. We removed the omentum from the catheter, and repositioned the catheter into the Douglas fossa. Although CAPD worked successfully after the operation, perfusion failure recurred one month after the operation. The patient requested discontinuation of CAPD and change to hemodialysis. Therefore, we removed the CAPD catheter. The catheter was adhered to the omentum. Reduced port surgery for peritoneal dialysis catheter obstruction has the advantage of being minimally invasive and is a reliable procedure, but further studies are needed to reduce the recurrence rate of perfusion failure and to establish the procedure after perfusion failure.
