title: [Short- and long-term monitoring with high-resolution ultrasonography of postoperative thyroid residue. Personal experience with 200 thyroidectomies].
abstract: BACKGROUND
  After having abandoned conservative operations of the thyroid (partial resection, enucleal resection) today total thyroidectomy and sub-total thyroidectomy and near total thyroidectomy are the operations of choice. Cause the frequent post-operative scintigraphic signs, on the 3rd month, of thyroidal residue of significative size, founded in our patients operated for sub-total thyroidectomy, we begun to study the echografical monitoring of the thyroidal recess.
  
  
  METHODS
  From January 1995 to December 1997 we operated 200 patients for Thyroidectomy. The kinds of operations were: total thyroidectomy for 96 patients (48%), sub-total thyroidectomy for 64 patients (32%), and near total thyroidectomy for 40 patients (20%). We controlled all the patients by ecografical monitoring of the thyroidal recess to detect and to determinate the possible thyroidal residue, that it will be monitorized on the 7th day, on the 1st month, on the 6th month and on the 12th month. We measured the thyroidal residual dimensions and volume. We recorded all the examinations by VCR or film and after we elaborated the results by exponential graphics. The patients that showed the thyroidal residues underwent to a scintigraphy.
  
  
  RESULTS
  The thyroidal residuals were measured within the 7Th post-operative day. In the following controls we have noted a thyroidal residue hypertrophy. Multinodular goither was the disease with the highest degree of growth (until the 200% of the first measure of the residue). After an initial phase of growth almost all the patients showed a trend to the stabilization, with the exception only of the patient that suffered from multinodular goither. The scintigraphic examination was not realiable, in our experience, about the mathematic measurement of the thyroidal tissue, showing always an overvaluation of the residue. The best specificity was showed by US-HR.
  
  
  CONCLUSIONS
  The patient that undergoes to total thyroidectomy needs an adequate suppressive and substitutive therapy. We identify the presence of several stimulating factors the growth of the residual thyroidal tissue that could arise to promote the hyperplasia and the hypertrophy of the parenchyma (EGF, TSG, TSI, PG). There are factors that are unidentified and are not subject to the suppression caused by substitutive therapy.
