Objective To analyze the efficacy of surgical treatment on differentiated thyroid cancer (DTC) complicated with lymphocytic thyroiditis (LT).Methods The clinical data of 147 patients with pathologically confirmed DTC and LT in our hospital from December 2013 to December 2015 were retrospectively analyzed.The operative time

average intraoperative blood loss

postoperative hospital stay

total effective rate

serum parathyroid hormone (PTH) levels and serum calcium levels at 1 day preoperation and postoperation

as well as the postoperative complications were analyzed. Results The operation time

average intraoperative blood loss and hospital stay of 147 patients were (126.23±30.65)min

(22.18±10.19)mL

(3.30±1.06)d

respectively.The total effective rate was 94.56%(139/147)

including 84 effective cases

55 valid cases and 8 invalid cases.The serum PHT and calcium levels at 1 day postoperation were lower than those 1 day preoperation(P<0.05).Postoperative complications occurred in 21 cases(14.29%)

including 3 cases of handfoot convulsions(2.04%)

5 cases of hoarseness(3.40%)

4 cases of dyspnea(2.72%)

1 case of asphyxia(0.68%)

5 cases of parathyroid injury(3.40%) and 3 cases of thyroid crisis(2.04%). Conclusion The application of the thyroidectomy plus regional neck lymph node dissection combined with the levothyroxine is an effective surgical treatment for patients with differentiated thyroid cancer with lymphocytic thyroiditis.
