Abstract
Low-thermal coagulation of pulmonary bullae by general-purpose radiofrequency cautery device in pneumothorax surgery
Highlights
Radiofrequency cautery is widely used in minor surgery, especially in the fields of plastic and cosmetic surgery, ophthalmology, head and neck surgery, gynecology, and urology
One English and two Japanese reports were found for Monopolar SealerTM [1,2,3,4] and only one Japanese report was found for SOFT COAGTM [5] Medtronic® Monopolar SealerTM EndoFB 3.0® Floating Ball, formerly-known as TissueLinkTM or known as Salient Surgical TechnologiesTM, is a radiofrequency device specializing in tissue sealing
High frequency is used for general radio wave broadcasting and communication, so it is often called as radiofrequency
Summary
Radiofrequency cautery is widely used in minor surgery, especially in the fields of plastic and cosmetic surgery, ophthalmology, head and neck surgery, gynecology, and urology. Air leakage from the stapling line is still annoying problem In these days, several electrosurgical devices that can cauterize the bulla wall and emphysematous tissue to get shrunk and thickened, without burnt, perforation, incision, carbonization, or destruction by low-thermal coagulation, are coming to the market. We report two cases of pneumothorax surgery using this general-purpose radiofrequency cautery device for coagulation/ ablation of pulmonary bullae by utilizing its low heat infiltration, with. Fifteen small bullae and blebs that were less than 1.0 cm in diameter, were cauterized with coagulation mode of Surgitron PellevéTM at the power of 10 watts, until they turned into whitish thickened structure, left unresected. The coagulated bulla wall was degenerated, thickened, and turned into non-structured tissue by heat infiltration at low temperature of radiofrequency. Any pathological evidence of heat infiltration into the lung parenchyma was not demonstrated
