[Endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch for chronic abdominal wall sinus].

Objective: To investigate the effectiveness of endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch for chronic abdominal wall sinus by comparing with the traditional surgical method.

Methods: Retrospective analysis was made on the clinical data of 53 cases of chronic abdominal wall sinus between January 2006 and May 2012. Of 53 patients, 18 underwent endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch (trial group), and 35 underwent traditional surgical treatment (control group).
