[Laparoscopic adrenalectomy at Shinshu University School of Medicine]

We report our experience with transperitoneal laparoscopic adrenalectomy in 26 cases (mean age 45 years). We experienced primary aldosteronism in 19 cases, Cushing syndrome in 6 cases and non-functioning tumor in one case. There was no significant difference in the operation time between right and left, men and women, primary aldosteronism and Cushing syndrome. The blood loss decreased with training. There were no severe complications during and after the operation. The weight of the resected adrenal glands increased. The blood loss decreased significantly compared with the open surgery. Transperitoneal laparoscopic adrenalectomy is becoming the safe and standard surgery for the adrenal gland tumor, and the number of suitable cases for this procedure is expected to increase in the future.
