title: [Transperitoneal laparoscopic adrenalectomy: surgical approach and outcome].
abstract: OBJECTIVE
  To investigate the efficiency and safety of transperitoneal laparoscopic adrenalectomy for the treatment of adrenal tumors and to describe surgical technique and management of intraoperative complications.
  
  
  METHODS
  From February 2002 to April 2008, 24 male and 44 female consecutive patients with average age (53.4 +/- 12.1) years old were treated with transperitoneal laparoscopic adrenalectomy because of adrenal tumors. Of the patients, 27 cases had right adrenal tumors, 39 cases had left adrenal tumors and 2 cases had bilateral adrenal tumors. The average tumor size was (2.9 +/- 2.0) cm with the maximal diameter of 10 cm. We evaluated this technique in respect of operating time, estimated blood loss, complications during surgery, postoperative complications, duration of hospital stay and pathological results.
  
  
  RESULTS
  All the surgeries had been completed successfully without conversion to open surgery. The average operating time was (157.7 +/- 51.5) min, the average estimated blood loss was (68.1 +/- 54.2) ml. No major complication happened during operation. The average drainage time was (2.6 +/- 1.5) days. The average post-operative hospital stay was (8.7 +/- 4.3) days. Four cases (6.0%) developed surgical field liquefaction and 2 cases (2.9%) experienced delayed closure of the drainage wound.
  
  
  CONCLUSIONS
  Transperitoneal laparoscopic adrenalectomy is feasible and safe in the treatment of adrenal tumor with low risk of intra-operative and post-operative complication.
