Secondary hyperparathyroidism (SHPT) is a common complication of end-stage renal disease. Surgical management occurs in severe forms and/or unresponsive medical treatment. The aim of this study was to outline the indications of parathyroidectomy and its evolution after surgical approach. It was a five-year multicenter backward study in Otorhinolaryngology Department of Fann Hospital and four dialysis centers in Dakar. We include all patients with SHPT who underwent surgery. Preoperative clinical and paraclinical parameters, clinical-biological evolution, and histology findings of the resected parathyroid specimen were collected. Out of 58 patients with hyperparathyroidism, 18 patients required parathyroidectomy, corresponding to a prevalence of 31%. Mean age of patients was 46.6 ± 15.29 years and sex ratio 0.61. Mean duration on dialysis was 44.4 ± 30 months. Ten patients (55.56%) had bone pain and nine patients (50%) had joint pain. Mean serum calcium was 97.27 ± 8.66 mg/L. Mean blood phosphorus levels were 40.47 ± 9.99 mg/L. Mean iPTH rate was 1493.22 ± 1014.93 ng/mL, with a maximum of 5000 ng/mL (77N). Mean value of 25-OH Vitamin D was 32.89 ± 16.02 ng/mL. Parathyroidectomy was indicated after failure of medical treatment with persistence of a serum intact parathyroid hormone concentration above 800 μg/mL in all patients. Subtotal parathyroidectomy (7/8) was performed in 11 patients (61.1%). Two patients (11.11%) benefited from a selective parathyroidectomy (3/4). Evolution was favorable for 13 patients, corresponding to a success rate of 72.2%. It was unfavorable in five patients including one patient with hypoparathyroidism and four patients with recurrent hyperparathyroidism. Surgery for patients with renal hyperparathyroidism in the era of calcimimetics continues to play an important role in selected patients and achieves efficient control of hyperparathyroidism in developing countries.
