To investigate the clinical result in open thyroid lobectomy and central lymph node(level Ⅵ) dissection using bipolar coagulation forceps.

The 72 cases of thyroid papillary carcinoma with open thyroid lobectomy and central lymph node(level Ⅵ) dissection treated in our hospital from Jan 2015 to Jan 2018 were divided into Group A (using bipolar coagulation forceps) and Group B (using monopolar coagulation) according to the different surgical instruments. The clinical data were recorded and compared between the two groups. SPSS 11.0 software was used for statistical analysis. The measurement data were compared by t test. The postoperative complication rates were examined by Chi-square. A P<0.05 was considered as significant difference.

The mean operating time [46.4±7.5 ) min vs. (70.8±11.1) min], blood loss volume[(6.0±3.4) ml vs. (15.5±6.0) ml]. in Group A were significantly lower than those in Group B (P<0.01). But the length of incision, drainage volume after operation, number of lymph node retrieved had no significant difference between the two groups (P>0.05). No case of postoperative bleeding was found. The total incidence of postoperative complications (2.5% vs. 15.6%) in Group A was significantly lower than Group B (P<0.05).

The bipolar coagulation forceps is an ideal tool in open thyroid lobectomy and central lymph node(level Ⅵ) dissection.
