Thoracoscopic Management of Pleural Effusion Resulting from Peritoneal Dialysis (PD Hydrothorax)
Recurrent pleural effusion secondary to peritoneal dialysis (PD hydrothorax) occurs in about 2% of patients on continuous ambulatory peritoneal dialysis (CAPD). It can potentially be a serious problem, resulting in permanent cessation of CAPD and transition to hemodialysis. This can have many adverse consequences for some patients. Thoracic surgeons are often called upon by nephrologists for a solution to this problem.
It is thought to occur as a result of movement of peritoneal dialysate through fenestrations in the diaphragm or pleuroperitoneal communications, facilitated by the negative intrathoracic pressure. Pleural fluid analysis typically detects a higher glucose concentration than serum.
Conservative management with temporary interruption of PD has a poor success rate, whereas the efficacy of thoracoscopic intervention has been associated with success rates exceeding 90%. In this video, the authors demonstrate and discuss their approach for the thoracoscopic management of PD hydrothorax.
