Application of Body Tom® mobile CT combined with basic anesthesia in preoperative painless localization of small pulmonary nodules: A retrospective cohort study / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective     To explore the application of Body Tom® mobile CT combined with basic anesthesia in preoperative painless positioning of small pulmonary nodules, and evaluate its safety and effectiveness. Methods     Patients using mobile Body Tom® CT to accurately locate pulmonary nodules in the Department of Thoracic Surgery of Affiliated Nanjing Brain Hospital, Nanjing Medical University from August to October 2022 were retrospectively included. Clinical data of the whole patient group were analyzed. Results    We finally included 30 patients with 12 males and 18 females at age of 23-71 years. The position success rate of 30 patients with small pulmonary nodules was 100.0%. Location time was 14.20±4.07 min. There was one patient of intrapulmonary hemorrhage, with no other complications such as pneumothorax, positioning needle shedding, or pleural reaction. The time from the end of positioning to the start of surgery was 12.63±5.68 min. There was no needle migration or indocyanine green overflow. All patients completed resection of small pulmonary nodules under single-port thoracoscopy, no transit to opening chest. The average operation time was 85.32±12.60 min. There was no postoperative complications, and the average postoperative chest tube retention time was 2.12±1.34 days. And the average length of hospital stay was 3.52±1.45 days. The postoperative pathological results showed that the distance from the nodules was greater than 2 cm. Conclusion     Body Tom® mobile CT combined with basic anesthesia can achieve the preoperative painless, precise positioning of pulmonary nodules, effectively reduce the incidence of preoperative positioning complications, shorten the operation waiting time, ensure the safety and effectiveness of patients with preoperative pulmonary nodules positioning, and further improve the surgical comfort of patients, which has certain clinical application value.
