POSTOPERATIVE COMPLICATIONS, HYPOPARATHYROIDISM, POSTOPERATIVE BLEEDING, INFECTION, EFFUSION, LYMPHATIC LEAKAGE, SCARRING
Significant differences were not observed in the general and pathological information (including sex, age, body weight, body mass index (BMI), incision length, specimen volume, Hashimoto’s thyroiditis, and number of lymph nodes dissected), operation time, and postoperative complications (postoperative bleeding, incision infection, lymphatic leakage, and temporary hypoparathyroidism) between the two groups. The patients in the non-drainage group had a shorter hospital stay (2.11 ± 0.33 d) than the patients in the drainage group (3.38 ± 0.90 d) (P<0.001). The amount of cervical effusion in patients in the non-drainage group (postoperative 24h: 2.20 ± 1.24 ml/48 h: 1.53 ± 1.07 ml) was significantly less than that in the drainage group (postoperative 24 hours: 22.58 ± 5.81 ml/48 h: 36.15 ± 7.61 ml) (all P<0.001). The proportion of incision exudation and incision numbness in the non-drainage group was lower than that in the drainage group (all P<0.05), and the pain score (VAS) and neck foreign body sensation score (FBST) decreased significantly (P<0.05). During the 3- and 6-month follow-up exams, significant differences were not observed between the THYCA-QoL and drainage groups and the non-drainage group, although the scarring and POSAS values were lower than those in the drainage group. In addition, the length of stay and cost of hospitalization in the non-drainage group were lower than those in the drainage group (P<0.05).
