Abstract

180 total thyroidectomy case studies performed by the same operator in the years 2006-2010, all done with sutureless technique (Ligasure precise(®)). The monitoring of patients involved a dose of serum calcium on the 1st, 2nd, 3rd and seventh post-operative, before the ambulatory monitoring of the patient. Treatment of post-operative thyroidectomy also includes the administration from the first day of post-surgery, of 2 g/day of calcium (calcium lactate gluconate 2940 mg, calcium carbonate 300 mg). Hypocalcemia was observed in 27 cases (15%) of which 23/180 (12.8%) were transitional and 4/180 (2.2%) were permanent. The average postoperative hospitalization was 2.5 days with a minimum of 30 h. The peak of hypocalcemia was of 11 patients on the first postoperative day (40.7%) in 6 patients on the second postoperative day (22.2%), in 8 patients on the third postoperative day (29.6%), in 1 patient on the fourth postoperative day (3.7%) and in another one on the fifth postoperative day (3.7%). The second postoperative day is crucial for the determination of early discharge (24-30 h). When the surgeon identifies and manages to preserve at least 3 parathyroid glands during surgery, the risk of hypocalcemia together with evaluations of serum calcium on the first and second post-operative day, eliminates the hypocalcemic risk.
