The traditional methodology in Ewing's sarcoma was chemotherapy and radiotherapy. Recently surgery is reemerging as an important therapeutic tool and some paper report increased survival with it. The purpose of this nonrandomized study is to evaluate our result of Ewing's sarcoma with surgery, retrospectively. We experienced 30 cases for seven years and among them 6 were extraskeletal. In location, axial was 10 cases and peripheral was 20. By Enneking's classification, state IIB was 26 cases and IIIB was 4. Eighteen patients took operation, chemotherapy and/or radiotherapy, and remaining twelve took chemotherapy and/or radiotherapy only. Type of operation was limb salvage in 16 cases and amputation 2. Average dosage of radiation was 45.1Gy. Six kinds of chemotherapeutic regimen were used, but among them main protocols were Ifosfamide-Adriamycin(17 cases) and IESS(Cytoxan, Adriamycin, Methotrexate, Vincristine:8 cases). Complications were as follows. In operation group, there were 3 local recurrence and one case of nonunion. In nonoperated group, one local recurrence and one pancytopenia resulting in death. Average follow up was 29.7 months. Kaplan-Meier's ten year actuarial survival rate for the whole 30 cases was 26.8%. Significant difference in survival exists between central and peripheral lesions(p=0.05, by log rank test). Types of chemotherapy and surgery itself showed no significance. But surgery is important in function and local control. More intensive chemotherapeutic regimen to prevent distant metastasis and combined surgery and radiotherapy may be needed in Ewing's sarcoma.

Recent advances in imaging techniques, surgery and combination anti-cancer chemotherapy have brought high survival rates in osteosarcoma. To investigate the survival rate, local recurrence and complications in treatment, we analysed 25 osteosarcoma cases who had been treated with preoperative neo-adjuvant chemotherapy, surgery and post operative chemotherapy at Department of Orthopedic Surgery, Catholic University. From May 1988 to April 1995, 42 cases of stage IIB osteosarcoma were admitted in Department of Orthopedic Surgery. Among them, 17 cases who didn't follow our treatment guidance were excluded in this study. The average age were 19 years. There were 21 males and 4 females. The involved sites were 4 humerus, 10 femur, 10 tibia and 1 talus. Eleven cases had received intraarterial cisplatin and intravenous adriamycin chemotherapy, and 7 T-10 protocol and 7 intravenous ifosfamide, ADR, methotrexate, cisplatin. Twenty-three cases were treated with limb salvage surgery, and 2 amputation. The average follow-up was 35 months(3~82). There were 14 cases of continuous disease free, 9 cases of died of disease, 1 case of alive with disease, and 1 case of no evidence of disease at final follow-up. There were three cases of local recurrence at 6,8 and 12 months after operation. The estimated Kaplan-Meier's 5 year survival rates for all, ADR-cisplatin group, T-10 protocol group, and ifosfamide regimen group were 6%, 73%, 44% and 72%, respectively.

Background Free tissue transfer is considered the gold standard option for the reconstruction of distal leg defects. Free tissue transfer using recipient vessels in the contralateral leg (cross-leg bridge) is a potential option to supply the flap if there are no suitable recipient vessels in the injured leg. Most studies have described this technique using end-to-end anastomosis which sacrifices the main vessel in the uninjured leg. This study evaluated the use of a cross-leg free latissimus dorsi muscle flap for the reconstruction of defects in single-vessel legs, using end-to-side anastomosis to recipient vessels in the contralateral leg without sacrificing any vessel in the uninjured leg. Methods This is a retrospective study that included 22 consecutive patients with soft tissue defects over the lower leg. All the reconstructed legs had a single artery as documented by CT angiography. All patients underwent cross-leg free latissimus dorsi muscle flap using end-to-side anastomosis to the posterior tibial vessels of the contralateral leg. Results The age at surgery ranged from 12 to 31 years and the mean defect size was 86 cm². Complete flap survival occurred in 20 cases (91%). One patient had total flap ischemia. Another patient had distal flap ischemia. Conclusion Cross-leg free latissimus dorsi muscle flap is a reliable and safe technique for the reconstruction and salvage of mutilating leg injuries, especially in cases of leg injuries with a single artery. As far as preservation of the donor limb circulation is concerned, end-to-side anastomosis is a reasonable option as it maintains the continuity of the donor leg vessels.

배경: 동맥 재건술 후에 발생하는 폐쇄성 합병증은 치료가 어렵고 재발 가능성이 높은 것으로 알려져 있다. 저자들은 동맥 재수술에 관하여 임상양상 및 수술방법, 사용된 이식편, 술 후 결과들을 분석하여 이식편 폐쇄에 영향을 미치는 인자를 알아보고 효율적인 치료 방침을 세우는 데 도움을 얻고자 하였다. 대상 및 방법: 1998년 1월부터 2002년 12월까지 부산대학교병원 흉부외과에서 시행된 173명의 동맥재건술 후 재수술을 받은 33명(55예)을 대상으로 조사하여 임상적 특성과 치초 수술의 유형, 재수술시까지의 경과한 시간, 사용한 이식편, 치료의 결과 등을 후향적으로 분석하였다. 결과: 33명 중 32명이 남자였고 재수술 당시의 평균연령은 63.5세였다. 첫 수술에서 재수술까지의 기간은 11.9개월이었고 원인질환은 동맥경화증이 28예, 버거씨병 5예였다. 동반된 질환은 고혈압 19예, 당뇨병 11예, 심부전 6예 등의 순이었다. 한 환자당 평균 1.67회의 재수술이 시행되었고 치초의 수술유형은 대퇴동맥-슬와동맥 우회술이 19예로 가장 많았다. 수술에 사용되었던 이식편은 PTFE가 25예, Dacron이 6예였고 이식편에 따른 재수술률은 차이가 없었다. 재수술은 혈전제거술이 20예, 혈관 성형술 18예, 우회로 재조성술이 13예, 요부 교감신경절제술이 4예에서 시행되었다. 재수술의 결과는 하지의 기능회복이 15명, 하지보존 7명, 슬상부절단 5명, 슬하부 절단 3명, 사망 3명이었다. 걸론· 하지 동맥 재건술 후 발생하는 폐쇄성 합병증은 유입 동맥이나 유출동맥의 폐쇄가 발생하며 생기는 경우가 많았다 치료의 방침은 최초의 수술방법과 사용된 이식편에 따라 다를 수 있고 무엇보다도 이식편의 감시가 중요한데 이차 수술의 시행빈도가 가장 높은 시기인 술 후 1년 이내의 이식편 감시가 중요하다고 생각한다. 또한 재우회로술 뿐만 아니라 방사선학적 중재술 및 교감신경 절제술과 같은 부가적인 치료도 적극적으로 시행하여야 하지 보존율의 향상을 기대할 수 있을 것이다.

Purpose: The venous flap is used as an alternative method to the standard free flap for the management of small and thin soft tissue defects. Especially, the venous flap has advantages of being thin, easy harvest and various donor sites, as well as it having lower morbidity. Yet their clinical applications have been limited by their unstable postoperative course and also by their complications such as partial necrosis. The aim of this study is to extend the clinical indications of venous flaps with using various methods. Methods: From May 2005 to March 2006, total of 19 patients(21 cases) underwent various venous flaps for soft tissue defects as a result of trauma(15 cases), facial skin cancer(3 cases), chronic ulcer(1 case) and surgical wound for congenital anomaly(2 cases). The arterialized venous free flap were applied in 18 cases, the pure venous free flap was applied in 1 case and the pure venous pedicled flap were applied in 2 cases. Among them, two flow-through arterialized venous free flaps were applied that used the great saphenous vein to reconstructed major arteries as well as the injured skin and soft tissues in the arm. All the flap were harvested from the volar wrist(11 cases), dorsum of foot(5 cases), thenar(2 cases), and medial thigh(3 cases). Results: The sizes of the flap ranged from $0.75cm^2$ to $264cm^2$(mean size: $40.06cm^2$). The follow-up period ranged from two to twelve months. In the majority of cases, we obtained satisfying results, which was the excellent reconstruction of skin and soft tissue defects and especially in the case of limb salvage, replantation and cancer reconstruction. However, there were 5 cases of partial necrosis and 2 cases of complete failure. The donor sites were closed primarily in 7 cases and wound closure with skin graft were in 14 cases. Conclusion: We conclude that the venous flap will not only be useful for reconstruction of small defect in the hand and foot, but also be useful for various other clinical indications.

Background: We report our 10-year experience with traumatic peripheral arterial injury repair at an urban level I trauma center. Methods: Between January 2007 and December 2016, 28 adult trauma patients presented with traumatic peripheral arterial injuries. Data were retrospectively collected on demographic characteristics, the mechanism of injury, the type of vascular injury, and physiological status on initial assessment. The analysis also included the Mangled Extremity Severity Score (MESS), Injury Severity Score, surgical procedures, and outcome variables including limb salvage, hospital stay, intensive care unit stay, and postoperative vascular complications. Results: Four (14.3%) patients required amputation due to failed revascularization. MESS significantly differed between patients with blunt and penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005). The amputation rate was not significantly different between patients with blunt and penetrating trauma (20% vs. 0%, respectively; p=0.295). The overall mortality rate was 3.6% (1 patient). Conclusion: Blunt trauma was associated with higher MESS than penetrating trauma, and amputation was more frequent. In particular, patients with blunt trauma had significantly higher MESS than patients with penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005), and amputation was performed when revascularization failed in cases of blunt trauma of the lower extremity. Therefore, particular care is needed in making treatment decisions for patients with peripheral arterial injuries caused by blunt trauma.

Aim: We conducted a study in China to assess the health-related quality of life (HRQoL) in patients treated on for malignant bone tumors after surgery, and investigate the possible determinants. Methods: The subjects were 120 patients surgically treated by amputation and limb-salvage for bone tumors during the period of June 2008 to June 2010. The Medical Outcomes Study Short Form 36 (SF-36) was employed to measure the HRQoL of all the patients before and after surgery. Results: With regard to the results of the general quality of life tool (SF-36), we observed a significant improvement of all the indexes of HRQoL after 6 months (p<0.05). PF, RP and BP scores showed significant increase between surgery after 6 and 12 months (p<0.05). The means of the HRQoL of bone tumor patients in our study were still much lower than those of general population in every domain, even 12 months after surgery. Logistic regression showed that female patients were found to have lower scores in physical component summary (PCS) than males (OR=0.64, 95% CI=0.35-0.89). Patients older than 15 years had lower scores in mental component summary (MCS) (OR=0.60, 95% CI=0.32-0.86). Ablative surgery was related to both lower MCS and PCS scores (For MCS, OR=0.54, 95% CI=0.31-0.83; for PCS, OR=0.43, 95% CI=0.25-0.73). Conclusion: Our study showed the treatment for bone tumor could greatly alter the HRQoL of patients. Age, sex and type of surgery were associated with physical or mental HRQoL after surgery.

Osteosarcoma is the most common primary bony malignancy and its survivorship has been progressed markedly through refined chemotherapy and surgery. But still there are many non-responders and analysis of prognostic factors may be helpful for them. Two hundred and sixty-six patients were enlisted between Mar, 1985 and Sep. 1994. Among them our inclusion criteria were: 1)primary, nonmetastatic classical osteosarcoma 2)extremity in location 3)no prior treatment at other institute and completed neoadjuvant chemotherapy and surgery according to our protocol. One hundred and eleven cases were eligible. Analyzed factors were:age, sex, location, tumor size, and pathologic response. Statistical methods were log-rank test for univariate and Cox's test for multivariate analysis. Male to female ratio was 69:42 with an average age of 17.2 years. Locations of tumor were distal femur 59, proximal tibia 29, and proximal humerus 8. Tumor size were measured by its maximal diameter and 48 cases were above 10cm and 47 cases were below 10cm. For pathologic response, 57 cases showed more than 90% and 54 cases were less than that. Limb salvage procedure was 101 cases and amputation was 10 cases and their local recurrence rate were 3.6%. Average follow-up period was 24(9-78.2) months and their final status was CDF 86, AWD 8, NED 5, and DOD 12 cases. In univariate study: type of operation(p=0.005), tumor size(p=0.005), and pathologic response(p=0.02) were significant variables. Pathologic response(p=0.03) and type of operation(p=0.01) were meaningful prognostic factors on multivariate analysis. But the latter result was interpreted as a bias, so pathologic response remained as a sole meaningful prognostic factor. More aggressive chemotherapy will be needed to improve the survival.
