Tumor Treated by Endoscopy

Benign bone tumor is a typical disease encountered in the field of orthopedic surgery.As one of the palliative treatments, invasive curettage of the lesion has been widely used. 1) It is unavoidable, however, that palliative curettage is extremely invasive to soft tissue and the cortical bone in the lesions depending on the size of lesions.It is thus disadvantageous in that it may lead to various complications such as delayed union or bleeding, postoperative fracture due to a loss of the cortical bone and delayed wound healing and recovery at the operated sites.[2][3][4] To reduce these undesirable side effects, Stricker 5) first reported on endoscopic curettage in 1995.In 1999, Bonnel et al. 6) reported that endoscopic curettage and bone graft were performed for simple bone cyst of the calcaneus.Thereafter, several Background: This study was conducted to examine the clinical usefulness and efficacy of endoscopic curettage on benign bone tumor.Methods: Thirty-two patients (20 men and 12 women) with benign bone tumor were included in the study.The patients were aged between five and 76 years; the mean follow-up period was 27.05 months (range, 9.6 to 39.9 months).The primary sites include simple bone cyst (9 cases), fibrous dysplasia (6 cases), enchondroma (5 cases), non-ossifying fibroma (4 cases), bone infarct (3 cases), aneurysmal bone cyst (1 case), chondroblastoma (1 case), osteoblastoma (1 case), intraosseous lipoma (1 case), and Brodie abscess (1 case).A plain radiography was performed to assess the radiological recovery.Radiological outcomes, including local recurrence and bone union, were evaluated as excellent, good, poor, and recurred.Results: In our series, there were 27 cases (84.4%) of good or better outcomes, six cases (18.8%) of complications (4 local recurrence, 1 wound infection, and 1 pathologic fracture).Conclusions: Our results showed that endoscopic curettage and bone graft had a lower rate of recurrence and a higher cure rate in cases of benign bone tumor.It can, therefore, be concluded that endoscopic curettage and bone graft might be good treatment modalities for benign bone tumors.
