  • Injection of carbon nanoparticle suspension for Surgical Patients with non-small cell lung cancer

    Abstract: Surgery is an effective therapy for non-small cell lung cancer (NSCLC). The standard operation includes lobectomy and systematic dissection of lymph nodes. However, postoperative tumor recurrence is common even among incipient patients due to incomplete dissection of lymph nodes and micrometastasis of lymph nodes. Injecting a carbon nanoparticles suspension is a new technique aimed at preventing this recurrence. The carbon nanoparticles carry lymph node tracers that help surgeons locate lymph nodes in order to clean them thoroughly. The tracers also target the lymph nodes for chemotherapy, thus killing residual tumor cells intraoperatively to avoid postoperative cancer recurrence. Carbon nanoparticles suspension injection is already widely and successfully used in surgery for gastrointestinal and mammary gland tumors, and is being tested for effectiveness in NSCLC patients. Some studies have indicated that carbon nanoparticles suspension injection is effective in NSCLC patients and improves their prognoses. We reviewed the features, application methods, and clinical applications of studies of carbon nanoparticles suspension injection for NSCLC.

  • Analysis of the Inducement and Surgery Treatment of Esophageal Benign Diseases

    ObjectiveTo discuss the causes of esophageal benign diseases and how to prevent, diagnose and treat such diseases. MethodsWe reviewed and analyzed the clinical data of 162 patients with esophageal benign diseases treated in our hospital from March 1994 to July 2011. Causes, diagnosis, treatment and prognosis of this kind of diseases were analyzed and summarized. ResultsEighty-five patients had definite inducements. All patients were diagnosed through barium swallow radiography, CT, and gastroscopic inspection and underwent operation. A total of 155 patients were cured by positive treatment, but 7 patients died because of severe infection. ConclusionMost patients suffering from esophageal benign diseases have definite inducements. Therefore, many such diseases can be prevented. Once being confirmed, active surgery is the main treatment. Most patients can be cured if treatment is performed in time.

  • 非胸腔镜辅助Nuss手术治疗漏斗胸123例

    目的总结Nuss手术治疗漏斗胸及减少术中、术后并发症发生的临床经验。 方法回顾性分析2010年6月至2013年3月四川大学华西医院123例漏斗胸行Nuss手术治疗的临床资料,男101例,女22例;年龄3~32(15.0±5.1)岁;身高80~183(155.5±25.0)cm;体重15~71(44.4±13.3)kg。其中2例为Ravitch术后复发患者,其余患者均为初次手术。术前胸部CT示:Haller指数为4.1±1.4。 结果所有患者均顺利完成手术,手术时间35~155(74.3±25.4)min,术后住院时间3~16(4.2±1.6)d。其中26例患者需植入2根矫形板,其余患者均只需植入1根矫形板。CT示:术后Haller指数为2.6±0.6,与术前比较差异有统计学意义(P<0.05)。术后共发生并发症15例,发生率12.2%。其中气胸4例次,切口感染5例次,1例患者考虑为机体对矫形板材质过敏,伤口长期渗血、渗液,最终患者选择提前取出矫形板;2例患者有轻度脊柱侧弯,7例患者术后1~3个月内发生矫形板移位,需再次手术,重新放置矫形板。 结论Nuss手术安全、可靠,具有矫形效果佳、损伤小、恢复快等优点。
