title: Posterior retroperitoneoscopic partial adrenalectomy using ultrasonic scalpel for aldosterone-producing adenoma.
abstract: BACKGROUND
  Posterior retroperitoneoscopic adrenalectomy has become a standard procedure, but removal of the entire gland is not necessary in all cases.
  
  
  METHODS
  We performed 10 posterior retroperitoneoscopic partial adrenalectomies for aldosterone-producing adenoma (APA) using an ultrasonic scalpel to divide the normal adrenal gland and the adenoma.
  
  
  RESULTS
  The mean operation time and blood loss were 154 (110-231) minutes and 11 (5-32) mL, respectively. The mean weight of removed tissue was 5.7 g (2.3-10.2 g). Subcutaneous emphysema occurred in three patients, but there were no serious operative complications.
  
  
  CONCLUSIONS
  Posterior retroperitoneoscopic partial adrenalectomy using the ultrasonic scalpel may be a valuable treatment for typical solitary APA.
