Robotic assisted adrenalectomy: Surgical techniques, feasibility, indications, oncological outcome and safety

• The majority of patients undergoing robotic assisted adrenalectomy are treated for benign disease.
• There are only a few case reports of robotic assisted adrenalectomy performed for malignant disease.
• Robotic assisted partial adrenalectomy seems especially promising for hereditary pheochromocytoma.
• Robotic assisted adrenalectomy could possibly elicit a mild surgical response instead of the well described surgical response.

Nowadays robotic assisted adrenalectomy has become an alternative to conventional laparoscopic adrenalectomy. However, evidence on the possible advantages and drawbacks of robotic assisted adrenalectomy remains still limited. This manuscript aimed to review evidence on robotic assisted adrenalectomy in terms of surgical technique, feasibility, indications, oncological outcome and safety. Existing evidence, although limited, suggests that robotic assisted adrenalectomy is feasible and safe. However, the number of patients submitted to robotic assisted adrenalectomy is limited with the majority of them being operated for benign disease. There are only a few case reports of robotic assisted adrenalectomy performed for adrenocortical carcinoma, oncocytoma or metastasis. Partial adrenalectomy seems to be a promising application of robotic assisted adrenalectomy especially for the treatment of hereditary pheocromocytomas. Robotic assisted adrenalectomy overcoming the technical limitations of laparoscopic surgery could possibly elicit a mild surgical response instead of the well described surgical response. Surgical response affects surgical morbidity and mortality as well as oncological outcome of malignant disease. If this hypothesis is proved correct, robotic assisted adrenalectomy could be possibly indicated in the treatment of disease. In conclusion, robotic assisted adrenalectomy is feasible and safe. Further research is needed on the oncological outcome of this minimally invasive technique as well as on its effect on surgical stress response.
