[Surgical treatment of secondary hyperparathyroidism. Results from 47 consecutive patients].
To date surgical treatment of secondary hyperparathyroidism (HPTs) is still controversial. Subtotal parathyroidectomy with sparing of a part of not-nodular gland and total parathyroidectomy with autotransplantation (subcutaneous or muscular) represent the most common procedures with the aim to warrant a condition of euparathyroidism. Total parathyroidectomy (or so presumed) represent an unusual therapeutic option as the risks arising from aparathyroidism and from the need of a substitutive therapy are largely known. The authors evaluate the surgical results collected from 47 consecutive patients affected by HPTs and Chronic Renal Failure (CRF) and operated on between January 1999 and January 2006. Probably, a proper indication to the type of surgical procedure could be based on the severity of the disease, on the age of the patient and on the expectation of transplant. The significant incidence of recurrence and persistent disease is due to autoimplantation or residual gland hypertrophy after subtotal parathyroidectomy, to the presence of supernumerary or ectopic glands, to cervico-mediastinic hypertrophy of cellular foci. The identification and removal of supernumerary glands, which may cause persisting hyperparathyroidism, is mandatory.
