Thoracoscopic surgery for management of pleuroperitoneal communication complicating continuous ambulatory peritoneal dialysis: A case report.

Abstract

Rationale:Pleuroperitoneal communication (PPC) has been reported to complicate continuous ambulatory peritoneal dialysis (CAPD). However, cases of patients in whom the results of the methylene blue dye test and peritoneopleural scintigraphy were negative and treatment was thoracoscopic surgery have been rarely reported.Patient concerns:A 58-year-old man with end-stage chronic renal failure who underwent CAPD presented with massive right-sided hydrothorax. The pleural fluid glucose level was high. Results of both the methylene blue dye test and peritoneopleural scintigraphy were negative.Diagnosis:The presence of end-stage chronic renal failure and diaphragm defects amenable to repair, which were identified during thoracoscopic surgery, indicated a definite diagnosis of PPC complicating CAPD.Interventions and outcomes:CAPD was performed twice after the defects were repaired during thoracoscopic surgery. There was no evidence that the repaired sites were leaking again, and the patient did not complain of any discomfort during the second CAPD.Lesson:Although special methods such as the methylene blue dye test and peritoneopleural scintigraphy may not be useful in some cases, thoracoscopic surgery is still effective and reliable in diagnosing and repairing diaphragmatic defects.
