Chest wall surgery used to be a subspecialty of traditional thoracic surgery, which has an ancient history of research and clinical practice. It has gradually become an independent professional field in recent years. With the change of concept and the progress of interdisciplines, we have deepened our understanding of related diseases, and the treatment of chest wall surgical diseases has also acquired new characteristics. This article reviews the progress in the treatment of chest wall surgical diseases including chest wall trauma, chest wall deformity, chest wall tumor, chest wall infection and chest wall defect from the perspective of chest wall surgery.
Objective To study the diagnosis and surgical treatment of multi-primary esophageal carcinoma. Methods The data of 29 patients of multi-primary esophageal carcinoma were collected .The diagnosis was made by dye-staining through gastroscopy and X-ray examination.Pathological examination after operation was analyzed.Three kinds of operations were used: 22 by radical resection, 5 by partial resection and 2 by surgical exploration. Results Twenty-one patients were diagnosed before operation,8 patients were diagnosed during and after operation. Sixty-seven foci and 6 early stage patients were found. The complications were found in 7 patients.No patient died during operation. Twenty-five patients were followed up. The follow up time was 7-36 months.1-year survival rate 77.8%,3-year survival rate 41.6%. Conclusion Routine X-ray examination of esophagus, and esophageal dye-staining and/or biopsy through endoscopy are important measures for early diagnosis of multi-primary esophageal carcinoma.Prompt surgery is advised.
Objective To explore the shortcomings of the traditional clinical probation teaching mode, propose and implement the interactive teaching mode, so as to stimulate the students’ interest in knowledge and achieve better teaching effects. Methods The students of Grade 2017 who had clinical probation in the Orthopaedic Trauma Center of West China Hospital of Sichuan University from September 2020 to December 2021 were selected. Students were randomly divided into traditional clinical probation teaching mode group and interactive teaching mode group according to random number table method. Wechat mini program anonymous questionnaire survey was used to evaluate students’ satisfaction with the interactive teaching model of orthopaedic trauma and the teaching effect. Results A total of 110 students were enrolled, 55 in the traditional clinical probation teaching mode group and 55 in the interactive teaching mode group. There was no significant difference in gender or age between the two groups (P>0.05). The students in the interactive teaching mode group were better than those in the traditional clinical probation teaching mode group in orthopedic theory test (90.13±3.65 vs. 88.39±3.74; t=2.469, P=0.015) in the orthopedic theory test, teacher evaluation (89.15±2.94 vs. 87.56±3.12; t=2.751, P=0.007) and student self-evaluation (89.07±3.18 vs. 87.41±2.89; t=2.865, P=0.005). The teaching satisfaction of the interactive teaching group was higher than that of the traditional teaching group (96.36% vs. 87.27%; Z=−2.159, P=0.031). Conclusion Interactive teaching mode can effectively stimulate students’ interest in knowledge seeking, improve the enthusiasm and interaction of clinical probation, and effectively improve the satisfaction of undergraduate orthopaedic trauma clinical probation teaching.
目的总结复杂腹腔镜胆囊切除术的操作技巧。方法对1996年8月至2003年1月我科施行的4 971例腹腔镜胆囊切除术中因各种原因所致手术操作困难者711例的临床资料进行回顾性分析。结果711例中687例在腹腔镜下运用顺行法或顺逆结合法完成胆囊切除手术，24例中转开腹，中转率3.4%，均治愈，无并发症发生。结论掌握好复杂性腹腔镜胆囊切除术中的操作技巧，能降低手术中转率以及手术风险，拓展腹腔镜的应用领域。
ObjectiveTo review the development and clinical application of ankle prosthesis.MethodsThe recent literature on ankle prosthesis design and clinical application was reviewed and analyzed. ResultsCompared with the hip and knee prostheses, the ankle prosthesis develops slowly and has been developed to the third generation. The ankle joint has a special structure of multi-axis movement. The design of the first and second generations of prostheses is not conformed to the biomechanics of the ankle. The third generation of prosthesis is more conform to the characteristics of ankle biomechanics, with high postoperative survival rate and satisfactory clinical outcome. ConclusionAt present, the survival rate of ankle prosthesis is low, and there is still much room for improvement in biomechanics, materials, and other aspects.
目的:探讨陈旧性髌骨骨折的最佳治疗方案。方法:我院1997.1～2007.12收治陈旧性髌骨骨折患者20例,均采用术前髌骨牵引、股四头肌锻炼,术中髌前纵形S切口、改良张力带固定骨折块,配合关节腔注射玻璃酸钠,术后早期行患肢CPM机功能锻炼。结果: 所有患者均获得随访,随访时间1.5～3.5年,平均2.2年。患者术后X片髌骨骨折块对位良好、关节面平整。术后切口甲级愈合,下床时间2d～21d,平均6.5d。骨折愈合时间3.0～6.5月,平均4.2月。术后1.5年膝关节HSS功能评分:优8例,良8例,可3例,差1例,优良率80%。结论: 术前牵引、术中正确处理骨折、术后术后早期锻炼等综合治疗陈旧性髌骨骨折疗效显著。
