Introduction

Methods

Tertiary hyperparathyroidism is a frequent, serious problem in patients with advanced chronic kidney disease (CKD). This is a state of excessive secretion of parathyroid hormone after longstanding secondary hyperparathyroidism resulting in hypercalcaemia. It manifests clinically with malaise, bone pain, metabolic complications and calcium deposition.

A retrospective review of all parathyroidectomies for renal hyperparathyroidism in a tertiary referral centre between 2000 and 2014. Groups were sub-divided into total (T) and sub-total (ST) parathyroidectomy. MM was graded as: •  1 (Vit-D/Calcium) •  2 (Cinacalcet) •  3 (Cinacalcet + Vit-D/Calcium).

Overall, there is approximately a 10% risk of recurrence or persistent disease in those requiring parathyroidectomy. This may be due to a hyper-functioning or missed neck gland, or, if transplanted, hyperplasia of the autograft1.

22 T and 10 ST cases were identified. 1 ST case was excluded from long-term follow-up as the patient died 20 days post-op due to a cardiac arrhythmia. This was not attributed to surgery and the patient’s calcium levels postop were within the normal range.

Medical management (MM) can be used to control disease progression in secondary hyperparathyroidism. However, surgery may be indicated In patients who do not respond to appropriate MM, or where there is severe hyperparathyroidism with hypercalcaemia1. Total (T) and sub-total (ST) parathyroidectomy are the most common procedures performed. Much of the literature reports higher rates of disease recurrence with ST compared to T2. However, ST may be associated with fewer post-operative complications and reduced in-hospital stay.
