title: Primary malfunction of a peritoneal dialysis catheter due to encasement in an encapsulating sheath.
abstract: Obstruction of the catheter is one of the potentially serious complications of peritoneal dialysis. Dislocation of the tip of the catheter, intraluminal fibrin formation, and omental wrapping are among the most common etiologies of peritoneal dialysis catheter malfunction that necessitate correction. Here we present a rare case of primary malfunction of a newly placed catheter in which multiple attempts to restore the patency by minimally invasive procedures were unsuccessful. Laparoscopy revealed a thick encapsulating sheath around the entire length of the catheter as the etiology of complete obstruction, without involvement of other intra-abdominal structures. The sheath was opened and the catheter was pulled out in its entirety. There was no intraluminal or orifice obstruction and it subsequently functioned perfectly.
