Parathyroid Re-exploration: A Clinical and Pathological Study of 112 Cases

摘要

In a series of 112 patients who underwent reoperation for primary hyperparathyroidism at the Massachusetts General Hospital between 1930 and 1975, all but 10 were treated successfully. Seventy-five initial explorations had been performed elsewhere, and 37 in our hospital. A total of 110 diseased parathyroids were uncovered—89 (81%) via re-exploration of the neck and 21 (19%) via mediastinotomy. In operation via the neck, the missing glands were most frequently found in the superior posterior mediastinum at the thoracic inlet (34, or 38%) and in mediastinal exploration, in the upper anterior mediastinum (14, or 67%). There were 66 patients with adenoma, 7 with carcinoma, and 29 with primary hyperplasia. Four had a hyperfunctioning fifth gland. One patient had an intrathyroidal and one, an ectopic gland. Reoperation was unsuccessful in 10 patients. Four died, and 6 are living.
