Abstract:Objective To evaluate the safety, efficacy and advantage of thoracoscopic costectomy in treatment of fibrous dysplasia.Methods The clinical data of 15 patients with costal fibrous dysplasia underwent thoracoscopic costectomy from February 2013 to August 2020 were retrospectively analyzed. There were 7 male and 8 female. The average age of the patients was (36.7 ± 12.6) years old (range, 16 ~ 52 years). The costal fibrous dysplasia were located on the left in 6 cases and on the right in 9 cases. The costal fibrous dysplasia were located in the fourth rib in 1 case, the fifth rib in 5 cases, the sixth rib in 5 cases, the seventh rib in 3 cases, the eighth rib in 2 cases, and the ninth rib in 1 case (17 ribs involved). All operations were performed by the same group of senior doctors. Thoracoscopic operation (2 holes, one for observation and the other for operation) was used to locate the lesion and the whole operation was completed by this method.Results All the operations of the 15 cases were completed successfully and the postoperative pathology was coastal fibrous dysplasia. The operation time was 45 ~72 min, with an average of (61.0 ± 10.5) min. The postoperative hospital stay was 3~5 days, with an average of (3.0 ±1.0) days. The postoperative pain score was 1~5 points, with an average of (3.3 ± 1.2) points. There were no serious complications. All the patients were followed up for 12~36 months, with an average of (24.5 ± 6.2) months, no recurrence was found.Conclusion Thoracoscopic costectomy in treatment of costal fibrous dysplasia is safe and effective. The procedure has the advantage in aspects of less invasive, pain and convenient. It is worthy of extending clinical application.
