Background:
The operative results of 100 laparoscopic adrenal resections in 94 patients and the subsequent impact on postoperative antihypertensive therapy are presented.
Methods:
Clinical and follow-up data for resections performed between 1995 and 2003 were obtained from medical records, patient questionnaires, and telephone interviews.
Results:
The diseases included Conn's syndrome (27 patients), Cushing's syndrome (30 patients), pheochromocytoma (11 patients), and Other tumors (26 patients). Antihypertensive therapy was eliminated or reduced for Conn's syndrome (75%), Cushing's syndrome (27%), pheochromocytoma (88%) and patients with Other tumors (54%). Clinical improvement was observed by 12 months for pheochromocytoma patients as compared with 35 to 45 months for the other groups (p < 0.05). Multivariate analysis showed that pheochromocytoma patients were more likely to experience improvement or cure than the Other tumor group (hazard ratio, 4.87; 95% confidence interval, 1.61-14.7).
Conclusions:
Laparoscopic adrenalectomy continues to be safe and efficacious for benign adrenal diseases. Although patients with functional tumors can expect improvement or cure, the time until improvement may be longer than previously recognized.
