Objective To explore the outcome of ultrasound-guided radiofrequency ablation in the treatment of overweight and obesity patients, and develop a more reasonable day-to-day surgical procedure.Methods A retrospective analysis of the patients undergoing day surgery of ultrasound-guided radiofrequency ablation of the great saphenous vein under fine management from July 1st, 2017 to June 30th, 2019 was performed. According to the body mass index (BMI), the patients were divided into normal group (18.5 kg/m²≤BMI<24 kg/m²), overweight group (24 kg/m²≤BMI<28 kg/m²), and obese group (BMI≥28 kg/m²). The observation items during and after surgery of each group were compared and analyzed. The quantitative data were presented as median (lower quartile, upper quartile), and the qualitative data were presented as frequency and/or percentage.Results A total of 189 patients were included, including 65 in the normal group [BMI: 22.6 (21.3, 23.4) kg/m²], 77 in the overweight group [BMI: 26.1 (25.3, 27.0) kg/m²], and 47 in the obese group [BMI: 29.7 (28.4, 31.2) kg/m²]. Radiofrequency ablation time in the obese group [195 (185, 215) s] was significantly longer than that in the normal group [185 (175, 195) s] and the overweight group [185 (177.5, 198) s] (P<0.05). The numerical rating scale score of postoperative 24-hour pain in the radiofrequency ablation area in the obese group [1 (1, 2)] was significantly higher than that in the normal group [1 (1, 1)] and the overweight group [1 (1, 1)] (P<0.05). The postoperative 1-month residual vein length in the normal group [1.0 (0.8, 1.3) cm] was significantly shorter than that in the overweight group [1.2 (0.9, 1.8) cm] and the obese group [1.3 (0.9, 1.8) cm] (P<0.05). The incidence of postoperative 1-month radiofrequency ablation area induration in the obese group (66.0%) was significantly higher than that in the normal group (10.8%) and the overweight group (20.8%) (P<0.05). The postoperative 3-month residual vein length in the obese group [1.2 (1.1, 1.4) cm] was significantly longer than that in the normal group [1.0 (0.9, 1.2) cm] and the overweight group [1.1 (1.0, 1.2) cm] (P<0.05).Conclusion Patients with BMI≥24 kg/m² undergoing day surgery of ultrasound-guided radiofrequency ablation of the great saphenous vein require longer radiofrequency ablation time, as well as more postoperative pain assessment and outpatient follow-up.
