Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.     

小儿肾积水Anderson－Hynes手术后并发症及其治疗

对５２例（５４侧）先天性肾盂输尿管连接部梗阻性肾积水患者行Ａｎｄｅｒｓｏｎ－Ｈｙｎｅｓ手术，对其手术的并发症进行分析，主要并发症为吻合口梗阻（３９％）和泌尿系感染（２８％）．经腹进行手术，肠梗阻发生率为１３％（３／２３）．患儿手术时年龄与手术后并发症发生率无显著性意义．     

动脉灌注灭活再植治疗骨肉瘤的体会

本组１２例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法，术后２年存活率平均为７５％，１例因经验不足致局部复发，仅占８．３％，表明在化疗保障下，采用此种方法即能保肢，又能获得与截肢治疗相同的手术效果，优于单纯行灭活再植术后中方法。     

胃癌D17S261和D17S799位点二核苷酸重复序列不稳定性的意义

目的研究二核苷酸重复序列不稳定性〔ＤＲＳＩ〕在胃癌发生中的作用及其临床意义．方法采用ＰＣＲ方法检测了Ｄ１７Ｓ２６１和Ｄ１７Ｓ７９９位点二核苷酸重复序列不稳定性．结果胃癌总ＤＲＳＩ发生率为３４％（１７／５０），其中高中分化腺癌ＤＲＳＩ阳性率（６６７％，１０／１５）显著高于低分化癌（１９４％，６／３１，Ｐ＜００１）；肠型胃癌ＤＲＳＩ阳性率（５５６％，１０／１８）显著高于胃型胃癌（２０％，６／３０，Ｐ＜００５），ＤＲＳＩ与胃癌部位、大小、浸润、分期、淋巴结转移无显著相关．结论ＤＲＳＩ在胃癌的发生中可能起重要作用．     

64例脾脏损伤手术的临床分析

目的探讨脾脏损伤有效的手术治疗方法。方法对手术治疗的64例脾脏损伤的病因、伤情分级、手术方法分析。结果64例脾脏中钝器伤45例,占70.31%,锐器伤19例,占29.69%。Ⅰ～Ⅱ级损伤26例占40.63%,Ⅲ～Ⅳ级损伤38例,占59.38%,64例患者死亡2例,均为Ⅳ级损伤,占3.13%。结论正确的手术方法,积极稳妥地处理合并伤是降低病死率的关键。     

内镜治疗上消化道异物160例临床分析

目的:总结上消化道异物在内镜下处理的经验。方法:根据异物的性质、大小和形状选择合适的方法，内镜下取出异物或设法让异物通过肠道排出体外。结果:160例患者中，155例通过上述方法取得满意的疗效，5例失败后改手术治疗，内镜治疗消化道异物成功率96．9％。结论:经内镜下治疗上消化道异物是一种有效、安全、经济的方法。     

阿托伐他汀对冠心病患者肱动脉内皮依赖性舒张功能的影响

目的：应用高频超声观察冠心病（CAD）患者，经阿托伐他汀治疗后对肱动脉内皮依赖性舒张功能（EDD）的改善作用。方法：经冠脉造影（CAG）确诊为CAD患者59例，利用高频超声血管技术检测阿托伐他汀对CAD患者治疗前后肱动脉EDD的疗效。结果：阿托伐他汀治疗2年后，EDD比治疗前有明显改善（P〈0．05），与对照组相比无显著性差异（P〉0．05）。常规治疗组治疗2年后，EDD无明显改善（P〉0．05），与阿托伐他汀组治疗后及对照组相比差异有显著性（P〈0．05）。结论：阿托伐他汀具有改善EDD的作用。
