Minimally invasive surgery for pleuroperitoneal communication complicating peritoneal dialysis.

Abstract

Pleuroperitoneal communication (PPC) is an uncommon but serious complication of continuous ambulatory peritoneal dialysis (CAPD). At present, there are many kinds of treatment options, with different effects. We describe our single-institutional experiences in the minimally invasive surgery of pleuroperitoneal communication complicating continuous ambulatory peritoneal dialysis in detail. Our study consecutively enrolled 12 pleuroperitoneal communication patients complicating CAPD. All patients underwent direct closure of the defective diaphragm and mechanical rub pleurodesis under video-assisted thoracoscopy. What is more, pseudomonas aeruginosa injection was infused into the thoracic cavity postoperatively to further promote pleural adhesion, which was the innovation of our study. After 1.0-8.3months of CAPD, all 12 patients presented hydrothorax in the right side. All these patients received surgery 7-179days (18.0 ± 49.5days) after onset. Bleb-like lesions situated on the diaphragm were discovered in all patients and three patients also had obvious hole on the surface of diaphragm. Pseudomonas aeruginosa injection was infused into the thoracic cavity postoperatively, and three cases showed fever with remission after 2-3days of symptomatic treatment. The time from surgery to restarting CAPD ranged from 14 to 47days, with a median of 20days. There was no recurrence of hydrothorax and transformation to hemodialysis during the follow-up period (median: 7.5months). Video-assisted thoracoscopic direct closure of the defective diaphragm and mechanical rub pleurodesis plus chemical pleurodesis using pseudomonas aeruginosa injection postoperatively is a safe and effective option for the treatment of pleuroperitoneal communication complicating continuous ambulatory peritoneal dialysis with 100% success rate.
