Our experience on laparoscopic partial adrenalectomy for surrenal adenoma

Aim: For adrenal lesions which are functional and bigger than four centimetres, the optional therapy is surgery. Laparoscopic surgery became gold standard therapy for adrenal lesions. In the past, total adrenalectomy was performed for any adrenal lesions without any exception; however, bilateral involvement of tumors like pheochromacytoma causes trouble and forced surgeons to try partial adrenalectomy. Recently, partial adrenalectomy is routine surgical procedure for bilateral lesions and also becoming common for unilateral lesions. We aimed to present short term results for patients who undergoes laparoscopic total or partial adrenalectomy. Methods: We collect data retrospectively for 33 patients who were operated in our clinic for adrenal mass between January 2010 and December 2014. 3 patients were excluded from study. All data were gained from personal patient medical records. Follow- up records were noted with one by one interviews by questioning steroid usage and symptoms of adrenal insufficiency. Findings: Patients were divided into two groups as total adrenalectomy group with 19 patients and partial adrenalectomy group with 11 patients. All patients who underwent total adrenalectomy have unilateral lesions, while 4 for 11 partial adrenalectomy patients have bilateral adrenal masses. Adrenal insufficiency developed in 3 patients for total adrenallectomy , 1 patient for unilateral partial adrenalectomy and 1 patient for bilateral partial adrenalectomy. Results- Discussion: Partial adrenalectomy appears to be protective for adrenal insufficiency for bilateral cases with a ratio of 75%. there were no significant difference between total or partial unilateral adrenalectomy group, considering postoperative complications, recurrance rates and insufficiency. As a result, laparoscopic partial adrenalectomy has similar results with less morbidity for unilateral lesions and an alternative method with less adrenal insufficiency for bilateral lesions. Laparoscopic partial adrenalectomy could be performed safely after learning period was completed and should be considered for adrenal surgeries.
