Experience on Retroperitoneal Laparoscopic Adrenalectomy in 401 Cases / 中国微创外科杂志

ABSTRACT

Objective To explore the value and efficacy of retroperitoneal laparoscopic adrenalectomy.Methods From August 2002 to December 2007,a total of 401 cases of retroperitoneal laparoscopic adrenalectomy were performed in our hospital.Among the cases,nonfunctioning adenoma was diagnosed in 151 patients;hyperaldosteronism was detected in 139,Cushing’s syndrome in 37,pheochromocytoma in 19,myelolipoma in 13,and other diseases were found in 42.Results Among the cases,5 were converted to open surgery because of difficulties in the operation due to a huge tumor(1),extensive adhesion between the tumor and the inferior vena cava(2),or massive bleeding(2).The other 396 cases of retroperitoneal laparoscopic adrenalectomy were completed successfully with a mean operation time of 105 minutes(30 to 270 minutes),and a median blood loss of 45 ml(20 to 1000 ml).Two of these patients had massive hemorrhage(1000 and 800 ml respectively),and received red blood cells transfusion(2 U) during the surgery.The rupture of the inferior vena cava or diaphragm occurred in two cases,and was repaired under a laparoscope.Follow-up was available for up to 1 to 64 months(mean 23.9) in 364 patients;none of them had long-term complications or recurrent benign tumors.Conclusions Retroperitoneal laparoscopic adrenalectomy should be used as the first choice for benign adrenal neoplasms,since the procedure is safe,effective,and minimally invasive,and the patients recovery quickly after the surgery.
