Pleuroperitoneal communication in patients on peritoneal dialysis. One hospital's experience and a review of the literature

Peritoneal dialysis is a treatment alternative in patients with advanced chronic kidney disease. The infusion of liquid into the peritoneal cavity leads to an increase in intra-abdominal pressure, which can sometimes produce leaks to the chest, giving rise to pleuroperitoneal communication. This is not a common complication, but it brings about high drop-out rates among patients using the technique. Diagnosis is easy and must be suspected in patients with sudden dyspnoea with low ultrafiltration and pleural effusion in the chest x-ray. Peritoneal rest and a temporary transfer to haemodialysis, and pleurodesis can be effective treatment strategies.
