RESUMO
Objective:To investigate the efficacy and application value of vacuum sealing drainage (VSD) in high-risk incision after bone and soft tissue tumor surgery.Methods:From January 2020 to September 2022, 22 patients with high-risk incisions after bone and soft tissue tumor resection in Shengjing Hospital, China Medical University were treated with VSD. The postoperative negative pressure was set at 0.025 MPa (188 mmHg, 1 mmHg = 0.133 kPa), and the VSD device was removed on the 7th day after operation. After removal, the wound healing and the incidence of related complications were observed.Results:After removing the VSD, 20 patients with high-risk incisions reached the standard of grade A healing, the rate of grade A healing was 90.91%, and 2 patients had incision wound necrosis, and the incision healed were improved after dressing change. The patients were followed up for 6 - 12 months, with an average time of 10 months. The wound healing of all patients reached the standard of grade A healing, and no long-term complications occurred.Conclusions:VSD technique has good clinical effect and can be applied to various high-risk incisions after bone and soft tissue tumor surgery, which can effectively prevent the occurrence of incision complications.
RESUMO
This report emphasizes on US diagnostic characteristics of partly BSTT,including OSteogenic sarcotma in 57 cases,chondrosarcoma in 25 cases, fibrosarcoma in 18 cases, synovial sarcoma in 14 cases, myelogenous neoplasm in 21 cases.metastatic bone ttmlor in 67 cases,giant cell turnor of bone in 52 cases, chordoma in 25 cases,hemangioma In 32 cases,desmoplastic fibroma in 10 cases. Pigrnenled villonodular synovius in 10 cases,and aneurysmal bone cyst in 8 cases, altogether 563 cases. The study firstly presents the application and specific menifestation of US diagnosis in BSTI. In many aspects,US is superor to X-ray, CT and MRI in diagnosing BSTT. It provides a great deal of reliable basis for clinical diagnosis and. Treatment.
RESUMO
In malignant bone and soft tissue tumors, lung is the most predilection site of metastasis and multiple pulmonary metastases is a poor prognostic factor. Aggressive treatment of pulmonary metastases may offer a chance of long term survival in selected patients whose primary tumors were controlled. We wanted to know the feasibility of pulmonary metastasectomy, whether it can prolong the survival. From Apr. 1989 to Dec. 1993, pulmonary metastasectomies were carried out for 20 patients, and followed up to Sept. 1994, with average follow-up period of 18.7(2-65) months. The primary malignant tumors were 8 in bone and 12 in soft tissues. Mean age was 27.5(12-70) years. Fifteen cases showed late metastasis after control of primary tumor(late metastasis group), and 5 cases showed pulmonary metastasis at first visit(initial stage III group). As a control we analyzed the survival of 24 cases of no treatment after pulmonary metastasis from bone or soft tissue sarcoma, during the same period of investigation. At final follow-up, in late metastasis group, 4 cases were in no evidence of disease (NED), 4 alive with disease (AWD) and 7 dead of disease (DOD). Tumor free interval (TFI) of NED and AWD was averaged 30 months, and for DOD 9.8 months. Five among 11 cases (45%) of multiple lung metastases and 3 among 4 cases (75%) of single metastasis were alive. In initial stage III group, 1 case was in NED, 1 AWD and 3 DOD. For late metastasis group, Kaplan-Meier's 5-year estimated survival rate from the first metastasectomy was 37.4%. The median survival period of 15 cases was 44 months. For initial stage III group, Kaplan-Meier's 9 months estimated survival rate was 40%. Median survival period was 8 months. Twenty four cases of no treatment cases died within 14 months from diagnosis of pulmonary metastasis. Their median survival period was 6 months. Pulmonary metastasectomy appears to prolong survival and occupies an important mode of treatment for late pulmonary metastases in malignant bone and soft tissue tumor patients. In the cases of initial stage III, more cases and follow up period are needed to have a conclusion.
