title: Comparison of laparoscopic and open adrenalectomy--a Singapore experience.
abstract: OBJECTIVE
  We present our experience with laparoscopic adrenalectomy for benign adrenal diseases and compare clinical outcomes with the conventional open approach.
  
  
  METHODS
  Between 1990 and 2001, two consecutive series of patients who underwent adrenalectomy for small, benign adrenal diseases were reviewed retrospectively. Patients with large tumours(> 7 cm), cancer and phaeochromocytoma were excluded. Fifty-eight patients underwent laparoscopic adrenalectomy and 48 patients had open surgery for benign adrenal diseases. Perioperative and postoperative records of both approaches were reviewed.
  
  
  RESULTS
  The two groups were comparable in terms of patient age, sex, weight and side of lesion.The common indications for surgery were Conn's syndrome and Cushing's syndrome. The sizes of tumour were comparable between the laparoscopic and open groups (mean, 2.1 cm vs 2.4 cm). Despite the longer operating time (mean, 128 minutes vs 87 minutes), the postoperative morbidity, parenteral analgesic requirement and length of postoperative hospital stay (3.2 days vs 7.2 days) were less inpatients undergoing laparoscopic adrenalectomy. Patients also enjoyed earlier return to oral intake and ambulation. There were fewer complications in the laparoscopic group. There was no conversion to open surgery.
  
  
  CONCLUSIONS
  Laparoscopic adrenalectomy is safe and has become the treatment of choice for small, benign adrenal lesions at our institution.
