Abstract:
Objective:To investigate the application of transoral robotic thyroidectomy (TORT) in overweight patients.Methods:Clinical data of 109 thyroid tumor patients who underwent TORT at 960th Hospital of People’s Liberation Army from May. 2020 to Aug. 2023 were retrospectively collected and analyzed. After excluding 10 patients who underwent prophylactic lateral neck dissection, a total of 99 patients were included in this study. According to the World Health Organization (WHO) guidelines, which define people with BMI:25-29.9 kg/m 2 as overweight, we divided the 99 patients into normal weight group (n=69) and overweight group (n=30) . To make the baseline data consistent between the two groups and ensure comparability, 20 matched pairs were generated using a 1∶1 propensity score matching (PSM) method, considering four clinicopathologic factors: age, gender, diameter of tumor and operation scope. In the normal-weight group, there were 18 females and 2 males, aged (32.82±9.51) years (range: 17-53 years) , and there exhibited 18 females and 2 males in the overweight group, aged (35.14±10.63) years (range: 18-55 years) . Results:All patients successfully underwent the operation without conversions to open surgery. After matching, both groups had 2 cases of thyroid adenoma and 18 cases of papillary thyroid carcinoma ( P=1) , with no statistically significant difference in the surgical scope between the two groups ( P=0.376) . There was no statistically significant difference in the mean tumor diameter between the normal-weight group and the overweight group (5.38±1.79 mm vs. 5.61±3.32 mm, P=0.575) . All malignant tumor cases in both groups were classified as T1 stage, and there was no statistically significant difference in N stage ( P=0.186) . All patients with malignant tumors underwent central lymph node dissection, there was no significant difference in the number of central lymph nodes dissected ( P=0.623) and metastatic lymph nodes ( P=0.109) between the two groups. There were no statistically significant differences in operative duration (217.53±62.83 min vs. 220.67±73.73 min, P=0.808) , median postoperative hospital stay [6 (6,7.75) days vs. 6 (6,7) days, P=0.682], or 24-hour drainage volume (78.52±30.49 mL vs. 68.23±29.11 mL, P=0.180) between the normal-weight group and the overweight group. There was no permanent hypoparathyroidism, postoperative hemorrhage, lymphatic fistula, mental nerve injury, postoperative infection in both groups. In both groups, there occurred one case of transient hypoparathyroidism. As for other complications, 1 case of temporary recurrent laryngeal nerve injury and oral tearing occurred in the overweight group, while the normal-weight group had 1 case of skin scald. Conclusions:Among patients who underwent TORT, the overweight group exhibited comparable surgical outcomes and postoperative complications to those in the normal-weight group. TORT is a safe and feasible surgical option for overweight patients, which provides more surgical options for this patient population.
