[Electroablation for the treatment of spontaneous pneumothorax using SOFT COAG electrosurgical output system].

We evaluated the validity of the SOFT COAG electrosurgical output system for the treatment of spontaneous pneumothorax. From April 2008 to May 2010, we compared 64 patients who had undergone bullae resection using endoscopic linear staplers, to 20 patients subjected to electroablation of the bullae using the SOFT COAG output system. There was no significant difference between the 2 groups in terms of operation time, bleeding, and mean duration of postoperative chest tube drainage. Postoperative recurrence was apparent in 3 cases for the linear stapler, and in 2 cases for SOFT COAG. Electroablation using the SOFT COAG output system was suggested to be valid for treatment of spontaneous pneumothorax.
