Patients who underwent unilateral lobectomy and neck lymph node dissection at the First Hospital of Jilin University from November 2021 to May 2022 were selected for this study. Patients were randomly divided into two groups by opaque envelope method: a non-drainage tube after operation group and a routinely placed drainage tube after operation group (The type of drainage in the drainage group was closed negative pressure drainage, which is placed after thyroidectomy, and punctured out 1cm away from the incision).Patients with the following conditions were excluded: those who did not agree to undergo the study, those with prior thyroid surgery, those with a history of hyperthyroidism, and those with systemic chronic diseases, such as hypertension and diabetes. A total of 104 patients were enrolled in this study (n=104) (Trial profile: CONSORT analysis.The general data of the patients were recorded, including the sex, age, body weight, body mass index (BMI), incision length, hospitalization days, hospitalization costs, and operation duration. For patients with drainage after thyroidectomy, when the drainage volume is less than 10ml within 24 hours, the drainage tube is removed, and the patients discharged. The pathological information of the patients was recorded, including the specimen volume, number of lymph nodes dissected, and presence of lymphocytic thyroiditis. The amount of postoperative drainage or cervical effusion and postoperative complications, such as postoperative bleeding, incision infection, lymphatic leakage, sound changes, and hypoparathyroidism, were recorded. For patients without drainage after thyroidectomy, their neck effusion was estimated by ultrasound by measuring the three-dimensional maximum diameter of the hypoechoic area of the thyroid bed in the neck. The patient with symptoms such as neck swelling and dyspnea within 24 hours after surgery which need re-operation was defined as postoperative bleeding. Patients with parathyroid hormone levels below 15.0pg/ml on the first day after surgery was defined as temporary hypoparathyroidism. The overall comfort of the incision area was determined using the pain score (VAS), incision exudation (Some patients were found to have exudation on the surgical dressing during the routine observer after surgery), foreign body sensation in the throat score (FBST), and incision numbness. The quality of life and cosmetic satisfaction of the patients were evaluated using the THYCA-QoL and POSAS values at 3 months and 6 months, respectively.
