title: Single-incision retroperitoneoscopic adrenalectomy and single-incision laparoscopic adrenalectomy.
abstract: OBJECTIVE
  Single-incision surgery is by now practicable in many fields of surgery, including surgery of the adrenal gland. We report on first experience with laparoscopic transperitoneal and retroperitoneoscopic single-incision adrenalectomy.
  
  
  METHODS
  Between September 2009 and February 2010, eight patients underwent single-incision adrenalectomy. Four patients received single-incision retroperitoneoscopic adrenalectomy, and four patients transperitoneal single-incision laparoscopic adrenalectomy. Technical feasibility and perioperative data are presented.
  
  
  RESULTS
  All patients had benign adrenal tumors (Conn's adenoma, n = 7; pheochromocytoma, n = 1). Tumor size ranged between 1.2 and 2.4 cm. Mean operation time was 76 minutes for single-incision retroperitoneoscopic adrenalectomy and 82 minutes for single-incision laparoscopic adrenalectomy. Blood loss was irrelevant in both groups.
  
  
  CONCLUSIONS
  Single-incision adrenalectomy is safe and feasible in appropriate operation time, both by the retroperitoneoscopic technique and by the laparoscopic technique. It is also associated with good cosmetic outcome.
