The Results Of Retroperitoneal Laparoscopic Retention Of Adrenal Tissue Treatment For Aldosterone-producing Adenoma

Objective: In this series we evaluate the results of retroperitoneal laparoscopic retention of adrenal tissue treatment for aldosterone-producing adenoma.Methods : From Jan 2011 to Aug 2014,55 patients with a diagnosis of aldosteron-producing adenoma under retrospective laparoscopic adrenalectomy,including 21 cases of male,female 34 cases,with a age of 49.25±10.13 years,24 cases on the left,31 cases on the right.31 cases underwent retroperitoneal laparoscopic total adrenalectomy(LTA),while 24 cases underwent retroperitoneal laparoscopic partial adrenalectomy(LPA). Retrospective analysis of 55 cases of perioperative patients with all the information and follow-up of changes in plasma aldosterone,potassium and other indicators of the presence or absence of blood pressure in patients with recurrent postoperative recovery.Results:All procedures were finished laparoscopically without transfusion,and no conversion was necessary.There were no differences with regard to age,sex,and tumor size as well as preoperative blood pressure,serum aldosterone,rennin,and potassium levels between the two groups.The perioperative and postoperative outcomes such as operative time,blood loss, and blood pressure significantly improved were similar between the two groups(P>0.05).During the month of follow-up period,there were no significant differences between LTA and LPA in term of prognostic composition of blood pressure with 18 cases cured,11 cases improved,2 cases failured in LTA versus13 cases cured,9 cases improved,2 cases failured in LPA.There were no significant differences between LPA and LTA in duration of surgery.No local recurrence was observed in all cases.1 case of LTA with postoperative blood pressure improved,24 months after the CT finding of bilateral adrenal adenoma,associated with elevated plasma aldosterone.The histologic examination showed adenomas in all cases.Conclusion: There were no significant differences between LPA and LTA in duration of surgery,intraoperative blood loss,operation and prognostic composition of blood pressure.We recommend it for patients with Conn’s syndrome who have unilateral and single tumors identified as adenomas.
