title: Videothoracoscopic thymectomy for nonthymomatous myasthenia gravis: results of 90 patients.
abstract: BACKGROUND
  Videothoracoscopic thymectomy is an alternative surgical procedure for patients with nonthymomatous myasthenia gravis. The aim of this study is to present our experience and to analyze the factors contributing to the operative morbidity.
  
  
  METHODS
  Ninety myasthenia gravis patients were operated through right-sided videothoracoscopy from June 2002 to September 2006. Prospective data recording was performed. Surgeon-related conversion to open surgery, length of the operation, chest tube duration time, duration of hospital stay, amount of drainage, pain score, and complications were evaluated. Factors contributing to longer operation time and longer postoperative stay were studied.
  
  
  RESULTS
  The mean length of chest tube duration and postoperative hospital stay was 26.7 +/- 18.6 hours and 2.2 days +/- 1.1 days respectively. Visual analogue scale (VAS) values for pain evaluation were 2.0 +/- 1.4. Surgeon-related open conversion occured in two patients (2.2%). Body mass index (BMI) was the sole significant factor for longer operation time. (23.04 +/- 2.93 versus 25.61 +/- 2.70 (p = 0.001). The amount of pyridostigmine was the only significant factor for longer hospital stay (213.3 +/- 101.5 mg versus 270. 0 +/- 122.6 mg (p = 0.044).
  
  
  CONCLUSIONS
  This study demonstrates the right-sided videothoracoscopy is a safe procedure. The only contributing factors were: BMI >25.61 for longer operation time, and pyridostigmine level >270 mg for duration of postoperative stay.
