title: Outcomes of laparoscopic adrenalectomy. Clinical experience with 68 patients.
abstract: The aim of this study was to analyze feasibility and outcomes of laparoscopic adrenalectomy (LA). Pathology, size and bilateral site of lesions were considered. Between December 1998 and May 2007 in our institution a total of 68 patients of mean age of 53 years underwent unilateral (n=57) or bilateral (n=11) LA. Adrenal masses averaged 5.4cm in size (range 1.2-13cm) and 56.7g in weight (range 10-265) including 71 benign and 8 malignant lesions. A total of 79 adrenal glands were resected, 44 right sided and 35 left sided. Removal was complete in 77 cases and partial (sparing adrenalectomy) in 1 patient affected by bilateral pheochomocytoma. Three left adrenalectomies for pheochromocytoma were robot-assisted. The transperitoneal lateral approach was preferred and the posterior retroperitoneal approach was adopted in 5 patients. The mean duration of surgery for each LA was 138+/-90min and 3.8 trocar were used on average (range 3-6). Conversion was needed in 3 cases owing to difficult dissection of large masses. Estimated mean blood loss for each LA was 95+/-30ml and it was greater for bilateral LA. Mortality was nil and morbidity was 5.8%. The average length of hospital stay (LOS) in surgical unit was 4+/-2.4 days (range 2-8). Patients affected by hormone secreting or bilateral lesions, by unilateral or bilateral pheochromocytoma and by bilateral Cushing's disease were transferred to the endocrinological ward so that their overall hospital stay was prolonged to 9+/-2.8 days on average (range 7-17). Mean duration of follow-up of patients was 38 months (range 2-100) and demonstrated acceptable endocrine results. Three primary cortical carcinomas were discovered as chance findings on histologic examination. While long-term results after LA for cortical carcinomas were poor and LA is not recommended in such cases, long-term results after LA for adrenal metastases were encouraging.
