Abstract
Pleuroperitoneal communication is a severe complication in peritoneal dialysis, and about half of the patients forced to discontinue peritoneal dialysis. The method of coloring dialysis solution by indocyanine green or CT peritoneography have been reported to make diagnosis of pleuroperitoneal communication, however sensitivity of these tests is not a satisfactory level. By repairing the pleural hole with thoracoscopic surgery, it is possible to resume peritoneal dialysis. However, the recurrence rate is very high unless precisely detecting the location of the pleural hole during surgery. We report three cases of pleuroperitoneal communication in peritoneal dialysis patients, in which we found the combination of contrast-enhanced ultrasonography and the indocyanine green fluorescence system are reliable method to make diagnosis and identify the location of leakage of pleuroperitoneal communication. By making definite diagnosis and precisely identifying the localization, we were able to close diaphragm holes by video-assisted thoracoscopic surgery.
