title: Clinical evaluation of gasless endoscopic thyroid surgery.
abstract: OBJECTIVE
  To determine the feasibility of gasless endoscopic thyroid surgery becoming a standard thyroid operation.
  
  
  METHODS
  We retrospectively examined the surgical results of 191 patients who underwent thyroid operations at our hospital between December 1999 and June 2003. We also conducted a survey based on a questionnaire sent to 150 patients who underwent thyroid surgery between December 1999 and September 2002.
  
  
  RESULTS
  Although gasless endoscopic thyroid surgery took significantly longer to perform than conventional open surgery, the postoperative stay was significantly shorter and patients had fewer complaints about their surgical scar.
  
  
  CONCLUSIONS
  These results indicate that although there are some challenges to overcome, especially the long operative time, gasless endoscopic thyroid surgery could become a standard procedure.
