Surgical outcomes from robotic-assisted adrenalectomy: a case series on experience in a large tertiary referral centre

Robotic-assisted surgery is gaining wider acceptance in most surgical specialties. However, in the United Kingdom, endocrine surgery has not fully adopted robotics. This paper aims to present the early experience and outcomes of patients who underwent robotic-assisted adrenalectomy at a tertiary referral endocrine surgery department. Outcomes were compared to national and international performance measures.

Seventy-two elective robotic adrenalectomies were performed over a 24-month period. Data collected included patient demographics, co-morbidities, indication for surgery and tumour size. Outcomes assessed were console time, conversion rates, complications, length of stay and excision margin.

Seventy-two cases were included for analysis. Sixty-six percent (n = 48) of the patients were female with a median age of 60 years. Median BMI was 28. Functional tumours accounted for 76% (n = 55) of cases with the most common being phaeochromocytomas and cortisol producing adenomas. Median docking time was 5 min with a median intraoperative time on the console of 45.5 min. Tumour size ranged from 1 to 14 cm. Median length of stay postoperatively was 1 day. There was only one conversion to open procedure. Two patients reported post-op superficial surgical site infections and there were no mortalities.

This case series demonstrates robotic-assisted adrenalectomies performed in a tertiary care centre were safe and feasible in a selected cohort of patients with functional and non-functional tumours. Large randomised controlled trials with long-term follow-up are required to establish the benefits of robotic adrenal surgery over conventional laparoscopic adrenalectomy.
