[Clinical study of laparoscopic adrenalectomy in Sapporo Medical University]

The purpose of this retrospective study was to identify the surgical outcome and complications of laparoscopic adrenalectomy at Sapporo Medical University Hospital. One hundred fifty-six patients underwent laparoscopic adrenalectomy due to primary aldosteronism in 64 (41.0%), Cushing's syndrome in 34 (21.8%), endocrinological non-functioning tumors in 27 (17.3%), pheochromocytoma in 23 (14.7%) and others. The median time of the surgery was 140 minutes (range 70 to 345) and the median volume of blood loss was 10 ml (0-1,200). From 1999, the operation time was around the median time of this study and from 2006, it was commonly below the median time of this study. There were 4 cases (2.6%) with complications; however, no severe cases occurred. In conclusion, laparoscopic adrenalectomy in our hospital has been performed safely as a standard treatment.
