Abstract
IntroductionThe primary hyperparathyroidism is a frequent disease whom the surgery is the only curative treatment. The preoperative location imaging techniques could help in the surgical management. Our objective was to analyze surgical results regarding the cure rate, etiology and location of the glands responsible for the primary hyperparathyroidism in patients with negative preoperative 99mTc-sestamibi scintigraphy. MethodsObservational study in patients with the diagnosis of primary sporadic hyperparathyroidism with negative 99mTc-sestamibi scintigraphy, operated consecutively in an endocrine surgery unit for 18 years. The cure rate, the intraoperatory PTH, the etiology and the pathological glands location were analyzed. ResultsIn the study were included 120 patients. After surgery 95% of patients (n = 114) presented cure criteria of hyperparathyroidism. 14.1% presented a multigland disease. 69% of the adenomas presented a typical perithyroid location, founding a percentage of 23.9% of ectopic adenomas in cervical location and a 7.1% in mediastinum. ConclusionsThe absence of uptake in the 99mTc-sestamibi scintigraphy should not condition the surgical indication. The success with experienced surgeons is similar to patients with positive results. The surgical indication must be established by clinical and biochemistry criteria.
