          Abstract

          A known complication of peritoneal dialysis is the movement of dialysate into the pleural space, termed hydrothorax. Peritoneal dialysis-related hydrothorax is almost uniformly right-sided and represents one of many presentations of the porous diaphragm syndrome. In addition to diaphragm porosity, the inherent intestinal circulation, lower hydrostatic pressure in the right upper quadrant and liver capsule may contribute to this right-sided predominance. Similar right-sided presentations have been described in Meigs syndrome, bilious effusions with gastric or duodenal perforations, hepatic hydrothorax and nephrotic syndrome-related chylothorax. PD-related hydrothorax can be repaired by pleurodesis or video-assisted thoracoscopy followed by resumption of peritoneal dialysis.

          Porous diaphragm syndromes.

          Porous diaphragm syndromes are a group of seemingly disparate clinical symptom complexes involving a wide variety of unrelated medical specialties. However, they are linked by a common anatomical feature, a defect in the diaphragm. They usually present with thoracic symptomatology--pleural effusions, pneumothorax, hemothorax, empyema--mediated by this defect. Management of these syndromes utilizes principles of thoracic surgical practice including thoracotomy and thoracoscopy.

            Acute Hydrothorax in Continuous Ambulatory Peritoneal Dialysis – A Collaborative Study of 161 Centers

            Follow-up studies on 3,195 patients from 161 centers in Japan undergoing continuous ambulatory peritoneal dialysis (CAPD) were performed for 1–104 months to clarify the incidence as well as the clinical features of acute hydrothorax. In these studies, 50 patients (1.6%) developed this complication. Twenty-seven (54%) were men, and 23 (46%) were women, ranging in age form 6 to 79 (average 49) years. The interval between onset of CAPD and hydrothorax ranged from 1 day to 8 years. Four had left-sided, and 2 had bilateral hydrothorax, but the majority (88%) were right-sided. Dyspnea was experienced by 37 of these 50 patients, but the remaining 13 (26%) patients were asymptomatic. Hydrothorax was fully resolved in 27 of them following a brief interruption of CAPD or the combined use of small exchange volumes in a semi-sitting position and pleurodesis with tetracycline or other agents. The remaining 23 patients (46%) were switched to hemodialysis permanently. Despite recurrence, 1 patient continued successfully on CAPD. It was concluded that acute hydrothorax is one important possible complication, although the risk may be low. Constant surveillance is necessary to detect pleural effusions in patients during CAPD.

              Management options for hydrothorax complicating peritoneal dialysis.

              Hydrothorax as a result of pleuroperitoneal communication occurs in approximately 2% of continuous ambulatory peritoneal dialysis (CAPD) patients. Although our understanding of its mechanisms is incomplete, it is apparent that the key to successful therapy is obliteration of a transdiaphragmatic route of dialysate leakage (pleuroperitoneal communication), possibly coupled with reduction of intra-abdominal pressure. This review corroborated the findings from 10 major population-based case series in which 60 of the 104 cases (58%) were able to resume long-term peritoneal dialysis (PD). Temporary interruption of PD alone was successful in half of them. As compared to this conservative approach, as well as chemical pleurodesis via intercostal chest drain, video-assisted thoracoscopic intervention (including direct pleurodesis and diaphragmatic repair) has shown a promising role. Efficacy of thoracoscopic treatment has been confirmed by several case series from various centers and the demonstration of a success rate in excess of 90%. With accumulating experience using the thoracoscopic technique, it remains to be seen whether this mode of treatment will obviate the traditional closed pleurodesis.
