Abstract:Objective To evaluate the feasibility and safety of endoscope-assisted low-temperature plasma adenoidectomy in ambulatory surgery mode.Methods It was retrospectively analyzed for the clinical data of 108 patients with adenoid hypertrophy admitted to the Department of Otolaryngology, Head and Neck Surgery, Foshan First People's Hospital from January 2018 to December 2018. A11 patients were divided into two groups[ambulatory surgery group (n=65) and inpatient surgery group(n=43)]based on their wishes. In ambulatory surgery group, the admission, operation and discharge were completed within 24 hours. It was compared for clinical data about surgery(duration time, bleeding volume), complications(pain, fever, bleeding) and inpatient quality indicators(duration before surgery, inpatient duration, total hospitalization costs and medicine costs) between two groups.Results All 65 patients in the ambulatory surgery group underwent surgery successfully. The operative time of the ambulatory surgery group and the inpatient group were (6.9±2.3) min and (7.5±2.8) min respectively, and the bleeding volume of the ambulatory surgery group and the inpatient group was (5.2±3.6) mL and (5.5±2.4) mL respectively, but there were not statistical significance for the data between the two groups(P>0.05). In the ambulatory surgery group, 3 patients without postoperative bleeding showed postoperative fever, and the average pain index score was (1.6±0.5) points, while in the inpatient group,6 patients without postoperative bleeding showed postoperative fever, and the average pain index score was (2.1±1.1) points, and there was no significant difference for the data between the two groups (P>0.05). The clinical efficacy was 96.9% (63/65) in the ambulatory surgery group and 95.3% (41/43) in the inpatient group respectively, and there was no significant difference for between the two groups (P=0.935). The preoperative waiting time and hospital stay in the ambulatory surgery group were (1.2±0.6) h and (10.5±2.8) h, respectively, which were significantly shorter than those in the inpatient group (21.5±5.8) h and (76.2±12.5) h (P<0.001); In ambulatory surgery group, the total hospitalization costs and medicine costs were(9 629.1±206.8) Yuan and (650.4±54.3) Yuan, which were significantly lower than that in inpatient surgery group(P<0.05).Conclusions In the ambulatory surgery mode, it is safe and effective to perform endoscopy assisted low-temperature plasma adenoidectomy. Compared with inpatient surgery, it can greatly shorten the preoperative waiting time and hospitalization time, reduce the hospitalization cost. It helps to reduce the consumption of medical resources and speed up the operation.
