Objective: To summarize experiences in 136 cases of retroperitoneal laparoscopic surgery. Methods:From April 1997 to May 2002, retroperitoneal laparoscopic surgery were performed for 136 cases of adrenal dis-eases. There were 63 aldosterone- producing adenoma, 22 adrenalcortical adenoma, 39 nonfunctional adrenal tu-mor, 7 adrenal cyst and 5 phenochromocytoma. Results: Except for one case converts to open surgery, success hasbeen achieved in all cases without major complications. Intraoperative blood loss was 76 + 32ml without blood trans-fusion. Postoperative hospital stay was 6 + 3 days. There were statistical differences among these indices when com-paring to those of open surgery for 126 cases with adrenal diseases( P ＜ 0.05). But operative time was little longer inlaparoscopic group than in group of open surgery(P＜0.05) ,whereas it has been changed to similar in those recentcases. Conclusion:Retroperitoneal laparoscopic surgery was less traumatic to the patients, with less postoperative dis-comfort and quicker recovery and should be considered the first choice of therapy for adrenal disorders.
