An 80-year old Caucasian woman with a 35-year history of left-sided ulcerative colitis (UC) underwent surveillance colonoscopy in January 2009.A random biopsy of the rectum revealed chronic colitis with low-grade dysplasia.A repeat colonoscopy in May 2009 revealed a polypoid area 3cm from the anal verge with histological examination revealing lowand high grade dysplasia.The patient declined colectomy and an attempt was made at local surgical excision.

自从射频消融术治疗心律失常问世以来,由于其成功率和安全性高,迅速在世界各地广泛推广.随着技术的进步和临床操作水平的提高,目前射频消融术已成为临床治疗快速性心律失常的一线治疗方法.近年来冷冻消融术也作为一种新的消融能源,开始在国内外应用于临床心律失常的消融治疗,其疗效也得到了临床实践和实验证实.与射频消融相比,在房颤的消融术中,冷冻消融术是一种安全无痛的术式,肺静脉狭窄的风险很低,特别是靠近房室结的
目的:分析肝动脉化疗栓塞(TACE)联合氩氦刀冷冻消融(AHCS)治疗原发性肝癌的近期疗效.方法:对31例原发性肝癌患者首先进行TACE治疗,3周后进行AHCS治疗.AHCS治疗后1周再次进行TACE治疗.全部介入治疗结束后1个月进行影像学及实验窜检查.根据RECIST标准、肿瘤坏死程度影像评价标准、治疗后AFP变化、外科手术治疗情况、不良反应、1年生存率等评价近期临床疗效.结果:总有效率为93.
