摘要
Delayed visceral organ perforations after PD catheter insertions are extremely rare. We report two patients who presented with asymptomatic visceral perforation from their buried PD catheters. Five months after a laparoscopic buried PD catheter insertion in a 92-year-old man PD was initiated; bile and bowel contents were noted in the PD effluent. He subsequently expired (from pneumonia) to autopsy revealed the PD catheter within the small bowel. Despite this perforation, there was no evidence of peritonitis, inflammation, nor any bowel content within the peritoneal cavity. A second case was observed 2.5months after an uncomplicated laparoscopic buried PD catheter insertion in a 60-year-old woman. PD was attempted; the patient had an immediate urge to void. MRI revealed the presence of the PD catheter within her bladder. She underwent PD catheter revision the next day with repair of bladder perforation and ultimately successfully initiated PD. Since the perforations did not occur at the time of catheter placement, we believe that the catheter eroded into a viscus, perhaps related to the lack of a fluid at the catheter - viscus interface. The diagnosis of delayed visceral organ perforation following buried PD catheter insertion may be delayed because the catheter is not immediately used.
