Communication Site Ligation and Polyglycolic Acid Sheet Use for the Treatment of Hydrothorax in Patients Undergoing Continuous Ambulatory Peritoneal Dialysis

摘要

Introduction: Hydrothorax due to pleuroperitoneal communication (PPC) can occur in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). We report our experiences of the safety and efficacy of the treatment of four patients with a novel video- assisted thoracoscopy method.Methods: Single-port video-assisted thoracoscopic surgery (VATS) was performed with a mini-thoracotomy of 5 cm in length. The PPC site was identified on the diaphragm and ligated using an endoscopic loop. The diaphragm was then covered using a polyglycolic acid (PGA) sheet, over which adhesive chemicals (OK432 and tetracycline) were sprayed.Results: We assessed the efficacy of our approach in four patients (one female and three males) aged 42–74 years (mean: 62.0 years). The hydrothoraxes were right sided in all the patients. The mean operation and postoperative drainage times were 92.5 min and 3.0 days, respectively. The hydrothoraxes did not recur in any patient during follow-up periods of 8–46 months.Conclusion: Our suture- and staple-free technique is not only easy to perform but also appears to be safe and effective for the management of hydrothorax in patients receiving CAPD. Larger scale studies are now indicated.
