Total Parathyroidectomy Under Local Anaesthesia for Renal Hyperparathyroidism

Abstract

Renal hyperparathyroidism with attendant osteodystrophy is a frequent and severe morbidity affecting the quality of life of end stage renal failure patients surviving on long-term renal replacement therapy. A small subgroup of these patients with severe cardiorespiratory dysfunction was deemed at very high risk for general anaesthesia (GA). We report on a series of total parathyroidectomy under local anaesthesia (LA) for these patients. Methodology: A total of 32 consecutive patients with severe cardiorespiratory dysfunction who underwent total parathyroidectomy under LA over a period of 7 years were prospectively accrued in this study. The patient characteristics, the operative outcome and the feasibility to surgery under LA were analyzed. Results: Sixteen of the patients (50%) had severe restrictive lung disease as a result of renal osteodystrophy and the other 16 patients had poor cardiac status. Histopathological examination confirmed 23 (71.9%) patients had four glands removed and seven (21.9%) patients had three glands removed. Two patients had only two glands removed and had recurrent hypercalcaemia. However, all patients reported symptomatic improvement. The post-operative complications were minimal; one patient had acute coronary syndrome and wound haematoma and another patient had wound haematoma which necessitated exploration under LA. A further patient developed congestive heart failure requiring treatment in the coronary care unit. Conclusion: Total parathyroidectomy can be performed safely and successfully under LA. We believe surgery under LA would be the most appropriate option for selected, high-risk patients to minimise the risk of GA.
