Is body mass index ( BMI ) at diagnosis associated with surgical wound complications in patients with localized osteosarcoma : a report from the Children 's Oncology Group?
Abnormal BMI at the start of treatment for localized osteosarcoma is associated with increased risk of post-operative wound complications such as arterial thrombosis. Future studies should evaluate whether maintenance of age-appropriate BMI reduces the risk of surgical complications.
ESD is an effective and safe therapy in the management of early gastric neoplasms when performed by well-trained endoscopists. Endoscopists should recognize the difficulty to perform ESD for en bloc resection of upper lesion, and the risk of delayed bleeding in cases of lesions >2 cm in size.
