Using the transperitoneal, laparoscopic approach, we performed 67 succ
essful adrenalectomies between June 1993 and July 1995 at Greenslopes
Hospital, Brisbane. There were 30 women and 37 men. Syndromes of prima
ry adrenal hormone overproduction-primary aldosteronism (n = 52), pheo
chromocytoma (n = 6), and hypercortisolism (n = 1)-were present in 59
patients and apparently nonfunctioning adrenal tumors (of which one wa
s malignant) in 8 patients. There was a significant difference in the
time of operation between patients weighing < 80 kg and those weighing
> 80 kg. Operations on males were slower than those on females, possi
bly explained by males being significantly heavier. Left-sided tumors
outnumbered right-sided tumors; removal of right-sided adrenals took,
on average, longer, but this difference was not significant.
