Laparoscopic Adrenalectomy for Conn's Syndrome is Beneficial to Patients and is Cost Effective in England

ABSTRACT

Purpose: Adrenalectomy has the potential to cure or improve the control of hypertension in patients with primary hyperaldosteronism due to unilateral adrenal adenoma (Conn's syndrome). This study assesses the patients' perception of, and costs associated with, laparoscopic adrenalectomy for Conn's syndrome. Materials and Methods: Clinical, radiological, operative, and pathological data were collected on patients undergoing adrenalectomy for Conn's syndrome over 8-years period in a UK tertiary referral center. Results: Thirty-eight patients (17M:21F, age 34–79 yrs, median 54 yrs) operated between Jan2005-Sept2012 had lateralization based on CT scans (n = 30) and/or MRI scans (n = 18) and confirmed on selective adrenal venous sampling (n = 25). Laparoscopic adrenalectomy was performed in all patients, with two cases requiring conversion to open operation. Median operative time was 105 min (range: 27–315). Costs were estimated as £19k for preoperative investigations, £20k for in-hospital stay, £53k for operating theatre use and £29k for disposable surgical instruments, with average £3499/patient (national tariff for adrenalectomy in 2015/2016 £3624). Follow-up at a mean of 30 months postoperatively using a visual analogue scale and a standardized questionnaire showed significantly improved quality of life (QoL) post-operatively. Majority of patients (85%) reported taking none or fewer anti-hypertensive medications (median reduction of 2 antihypertensive drugs). All patients stated that they would definitely have the operation again in preference to anti-hypertensive medications and they would recommend the operation to friends/relatives. Conclusions: Laparoscopic adrenalectomy for Conn's syndrome has a positive impact on hypertension control, leads to improved QoL and its costs are covered in the NHS financial model.
