Impact of adrenal surgeon volume on outcome: analysis of 4464 operations from the United Kingdom Registry of Endocrine and Thyroid Surgery (2 February 2024)

Summary

The adrenal glands are found in the fatty tissue at the back of the abdomen above each kidney, and produce steroid and adrenaline hormones. Surgery on tumours of the adrenal gland is uncommon compared with surgery for other tumours such as those of the breast, bowel, kidney and lung. Research has shown that the more adrenal operations a surgeon undertakes per year, the better the overall outcomes for patients undergoing that type of surgery.

In this study, the outcomes from adrenal operations recorded over 18 years in the national adrenal surgical registry were analysed. The results confirmed previous findings showing that postoperative complications and length of hospital stay were reduced for patients operated by surgeons who did more adrenal operations per year. Operations done by keyhole surgery had better outcomes. Operations done either in older patients, or for the rare adrenal cancer tumours had worse outcomes, as did operations in which both adrenal glands were removed. The authors recommended that all surgeons performing adrenal surgery should monitor the outcomes of their operations, ideally in a national registry, and discuss these with patients before surgery; and undertake a minimum of six adrenal operations per year, but a minimum of 12 per year if doing surgery for adrenal cancer or surgery to remove both adrenal glands.
