Thyroid lymphography:a new clinical approach for protecting parathyroid in surgery / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To research the role of lymph tracers to protect parathyroid in surgery for papillary thyroid carcinoma.</p><p><b>METHODS</b>Patients with papillary thyroid carcinoma who met selected criteria were enrolled in this study. Patients were divided into carbon nanoparticle group, methylene blue group, and conventional surgery group.</p><p><b>RESULTS</b>No significant complication occurred in the patients of carbon nanoparticle and methylene blue groups. In carbon nanoparticle group, methylene blue group and conventional surgery group, the mean numbers of parathyroid glands detected during surgery were 3.1 ± 0.3, 2.9 ± 0.4 and 2.3 ± 0.3 (F = 3.78, P < 0.01) , the rates that parathyroid was cut mistakenly were 1.37% (2/146) , 2.62% (2/97) and 7.14% (6/84) respectively (χ(2) = 17.372, P < 0.05) ; and the incidence of postoperative hypocalcemia were 10.4% (5/48) , 9.1% (3/33) and 17.5% (7/40,χ(2) = 0.671, P = 0.037) .</p><p><b>CONCLUSION</b>Thyroid lymphography technique is helpful to protect from the injury to the parathyroid glands in surgery.</p>

A prospective randomized and controlled study on no drainage after surgery for benign thyroid disorders / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To evaluate the necessity of drainage after thyroidectomy for benign thyroid disorders.</p><p><b>METHODS</b>A total of 272 patients who underwent thyroidectomy for benign thyroid disorders were randomly divided into drainage group or non-drainage group. Operating time, postoperative stay time in hospital, comfort of neck assessed by visual analogue scale (VAS) on postoperative day (POD) 0 and POD1 were and the incidence of complications, including post-thyroidectomy bleeding, hematoma, seroma, wound infection, hoarseness, and hypoparathyroidism, were assessed and compared between two groups.</p><p><b>RESULTS</b>Both groups were similar in the mean age, the sex ratio and the underwent procedure types. There was no significant difference in the mean operating time between two groups (87.5 ± 32.0) min and (93.8 ± 30.1) min (t = 0.12, P = 0.45). The mean postoperative hospital stay time of non-drainage group (1.9 ± 0.3) d was significantly shorter than that of drainage group (2.6 ± 0.6) d (t = 1.45, P = 0.02). The mean VAS scores of neck comfort on POD0 and POD1 in non-drainage group were significantly high than those in non-drainage group(t = 2.67, P = 0.03 and t = 0.33, P = 0.006). There were no significant difference in postoperative complications, including permanent hoarseness and hypoparathyroidism, between two groups.</p><p><b>CONCLUSIONS</b>No drainage after thyroidectomy for benign thyroid disorders does not increase postoperative complications, with the increase in postoperative neck comfort, the decrease in hospital stay time and potential wound infections. The routine drainage is not necessary after thyroid surgery for benign disorders.</p>
