  • 射频消融行保脾手术治疗体会(附24例报道)

    目的探讨脾外伤行射频消融保脾手术的适应证、手术特点及治疗效果。 方法脾外伤患者24例中,行腔镜下射频消融治疗9例,开腹对脾外伤裂口行射频消融止血或脾部分切除术15例(包括7例合并肝外伤)。 结果24例患者均顺利完成手术,手术时间(52±21)min(68~142)min。术后无明显出血、漏胆,腹腔感染等并发症发生,患者住院时间(5±2.1)d(4~16)d。 结论射频消融下保脾安全、可行,术后患者恢复快,住院时间缩短,不适为保脾手术的又一选择。

  • Clinical Experience of Totally Laparoscopic Bile Duct Jejunum Roux En-Y Anastomosis for 67 Cases

    目的总结完全腹腔镜下胆管空肠Roux-en-Y吻合的适应证、禁忌证、技术要点、安全性、并发症的预防及治疗效果。 方法回顾性分析2008年6月至2013年12月期间于笔者所在医院科室接受腹腔镜下胆管空肠Roux-en-Y吻合术的67例患者的临床资料。 结果67例患者中,66例完全在腹腔镜下完成手术,1例于放置蓝蝶后在手助下完成。手术时间144~253 min,平均152 min;术中出血30~220 mL,平均70 mL;术后住院时间6~11 d,平均8.1 d;住院费用2.0~2.5万元,平均2.1万元。术后发生漏胆3例,均经引流后痊愈;术后无肠瘘、出血、腹腔感染、肠梗阻等发生。术后20例患者获访,随访时间5~20个月,中位数为13个月。随访期间发生胆管炎2例,无吻合口狭窄发生。 结论对胆总管囊肿、胆总管下端良性狭窄、胆总管结石伴胆管扩张、壶腹部周围癌等需行胆肠吻合患者施行腹腔镜胆总管空肠Roux-en-Y吻合术是可行的,其手术费用稍高,但患者术后恢复快,且具有微创优势。

  • Research progress of electrospinning polyurethane fiber in the field of biomedical tissue engineering

    Polyurethane materials have good biocompatibility, blood compatibility, mechanical properties, fatigue resistance and processability, and have always been highly valued as medical materials. Polyurethane fibers prepared by electrostatic spinning technology can better mimic the structure of natural extracellular matrices (ECMs), and seed cells can adhere and proliferate better to meet the requirements of tissue repair and reconstruction. The purpose of this review is to present the research progress of electrostatically spun polyurethane fibers in bone tissue engineering, skin tissue engineering, neural tissue engineering, vascular tissue engineering and cardiac tissue engineering, so that researchers can understand the practical applications of electrostatically spun polyurethane fibers in tissue engineering and regenerative medicine.
