OBJECTIVES: To evaluate the effectiveness and safety of laparoscopic adrenalectomy with regard to adrenal mass size, as well as to consider its clinical and pathologic patterns. Laparoscopy is today considered the first-choice treatment of many adrenal diseases, although its use is still controversial for large adrenal masses and incidentally found adrenal cortical carcinoma. METHODS: A total of 125 patients underwent lateral transperitoneal laparoscopic adrenalectomy. The indications were either functioning or nonfunctioning adrenal masses, without any radiologic evidence of involvement of the surrounding structures. The correlation between the size and the operative times, estimated blood loss, incidence of intraoperative and postoperative complications, and length of hospital stay were studied with Pearson's correlation coefficient, Fisher's exact test, and the chi-square test. The analysis of variance test was used to evaluate any possible correlation between the size and clinicopathologic features and the results. RESULTS: A slight correlation was observed between the size and operative time (P = 0.004), but no correlation was observed between the size and the other parameters. Statistical analysis showed a significant correlation between the clinicopathologic patterns (nonfunctioning benign adrenal masses, Conn's adenoma, Cushing's adenoma, pheochromocytoma, adrenal cortical cancer, and other tumor metastasis) and the operative time (P = 0.011), but not with the other parameters. CONCLUSIONS: Laparoscopic adrenalectomy is also effective and safe for large lesions. The results of our series confirms that the risk of encountering an incidental adrenal cortical cancer is significantly increased for large lesions, and therefore, in these cases, additional attention is required to observe oncologic surgical principles.

Does adrenal mass size really affect safety and effectiveness of laparoscopic adrenalectomy?

Abstract

OBJECTIVES: To evaluate the effectiveness and safety of laparoscopic adrenalectomy with regard to adrenal mass size, as well as to consider its clinical and pathologic patterns. Laparoscopy is today considered the first-choice treatment of many adrenal diseases, although its use is still controversial for large adrenal masses and incidentally found adrenal cortical carcinoma. METHODS: A total of 125 patients underwent lateral transperitoneal laparoscopic adrenalectomy. The indications were either functioning or nonfunctioning adrenal masses, without any radiologic evidence of involvement of the surrounding structures. The correlation between the size and the operative times, estimated blood loss, incidence of intraoperative and postoperative complications, and length of hospital stay were studied with Pearson's correlation coefficient, Fisher's exact test, and the chi-square test. The analysis of variance test was used to evaluate any possible correlation between the size and clinicopathologic features and the results. RESULTS: A slight correlation was observed between the size and operative time (P = 0.004), but no correlation was observed between the size and the other parameters. Statistical analysis showed a significant correlation between the clinicopathologic patterns (nonfunctioning benign adrenal masses, Conn's adenoma, Cushing's adenoma, pheochromocytoma, adrenal cortical cancer, and other tumor metastasis) and the operative time (P = 0.011), but not with the other parameters. CONCLUSIONS: Laparoscopic adrenalectomy is also effective and safe for large lesions. The results of our series confirms that the risk of encountering an incidental adrenal cortical cancer is significantly increased for large lesions, and therefore, in these cases, additional attention is required to observe oncologic surgical principles.
