目的探讨食管癌患者年龄、吻合位置与术后并发症发生率和死亡率的关系,以及新辅助化疗对食管癌手术切除率的影响。方法回顾性分析西安交通大学医学院第一医院肿瘤外科自1997年~2003年首诊收治、资料完整587例食管癌患者资料。结果不同年龄组手术切除率分别为91.2%、95.9%和97.7%(P>0.05);>70岁年龄组术后吻合口瘘发生率和术后死亡率均较其它组高(P<0.05)。胸膜顶部吻合口瘘发生率为16.67%,较其它位置吻合口瘘发生率明显高(颈部2.17%、弓上1.09%、弓后2.60%、弓下0),具有显著性差异(P=0.019)。III期食管癌患者行术前新辅助化疗组与未化疗组的手术切除率分别为96.92%和78.85%,具有显著差异(P<0.05),而术后吻合口瘘发生率和术后死亡率无明显差异(P=1.000)。结论术前新辅助化疗可提高食管癌手术的切除率并不增加术后并发症。年龄大并不完全是手术禁忌,高龄患者的手术应充分考虑患者的生理年龄。 相似文献

Lacrosse requires the coordinated performance of many complex skills. One of these skills is shooting on the opponents’ net using one of three techniques: overhand, sidearm or underhand. The purpose of this study was to (i) determine which technique generated the highest ball velocity and greatest shot accuracy and (ii) identify kinematic and kinetic variables that contribute to a high velocity and high accuracy shot. Twelve elite male lacrosse players participated in this study. Kinematic data were sampled at 250 Hz, while two-dimensional force plates collected ground reaction force data (1000 Hz). Statistical analysis showed significantly greater ball velocity for the sidearm technique than overhand (P < 0.001) and underhand (P < 0.001) techniques. No statistical difference was found for shot accuracy (P > 0.05). Kinematic and kinetic variables were not significantly correlated to shot accuracy or velocity across all shot types; however, when analysed independently, the lead foot horizontal impulse showed a negative correlation with underhand ball velocity (P = 0.042). This study identifies the technique with the highest ball velocity, defines kinematic and kinetic predictors related to ball velocity and provides information to coaches and athletes concerned with improving lacrosse shot performance. 相似文献

外科作为临床医学核心课程之一,基本以课堂理论教学—实践课操作练习—毕业实习的模式展开,教学周期长达一年及以上。学科涵盖知识量大,教师在有限的理论课上呈现的往往是提炼、概括、浓缩后的知识点。而实践课及毕业实习一般采用传统"传帮带"的方式进行,一过性的演示不利于学生真正掌握技能。2011年微课概念被引入国内,作为一种新型信息教育形式,微课以其"主题突出、情境真实、短小精悍、交互性好"等特点被广泛认可。微课包括微课结合其他新型教育形式在逐渐应用于外科教学中,其效果得到越来越明确验证的同时,也暴露出了一些问题。 相似文献

Objective:To review our experience of the treatment of bilateral primary spontaneous pneumothorax (PSP) by video-assisted thoracoscopic surgery (VATS). Materials and methods: Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results: Twelve males and one female, with age ranging from 15 to 36 years (mean 23.1 years), were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously (n=4) or sequentially (n=9). The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients (84.6%) had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was (45.6±18.3) min (range 25-96 min) and (120.6±28.7) min (range 84-166 min) respectively for the non-simultaneous (second VATS for the recurrence of contralateral side after first VATS) and simultaneous (bilateral VATS in one operation) procedures. There was no postoperative mortality. However, prolonged air leakage (>7 d) occurred in one patient (7.7%) who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions: VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side. 相似文献

Although potassium is critical for normal electro physiology, the associations between pre-operative serum potassium level
and peri-operative adverse events such as arrhythmias in cardiac surgery have not been examined in detail.
The objective of this study was to determine the prevalence of abnormal pre-operative serum potassium levels and whether such
levels were associated with adverse peri-operative events in 50 patients undergoing coronary artery bypass grafting. Intra-operative
and post-operative arrhythmias, the need for cardio-pulmonary resuscitation, cardiac death and death due to any cause prior
to discharge from the post-operative intensive care unit were studied. The incidence for adverse outcome was 0.5% for death,
0.5% for cardiac death and 2% for cardio pulmonary resuscitation in patients with hypokalemia (serum potassium level <3.5
meq. L−1). Hypokalemia was found to be a predictor of serious peri-operative (OR:2.2; 95% Cl: 1.2–4.1) and post-operative arrhythmias
(OR: 1.7;95%Cl: 1.0–2.7).
Pre-operative potassium repletion is low cost and low risk treatment measure and the data from this study suggests that screening
and repletion be considered in patients scheduled for cardiac surgery. 相似文献
