Background and Aims: Ampullary impaction of an entrapped stone-basket complex is not an infrequent yet challenging event during endoscopic retrograde cholangiopancreatography (ERCP).The aim of this study is to evaluate the feasibility, safety, and efficacy of "post-cut" for the management of such scenarios.Methods: Patients with impacted biliary stone with an entrapped basket during ERCP at West China Hospital,Chengdu, China, between October 2004 to August 2014 were included in this retrospective study.Adequate biliary sphincterotomy was performed in all cases before attempted stone basket removal.Using free hand needle knife techniques, the authors extended the sphincterotomy along the long axis of the distal common bile duct to manage thebiliary stone-basket impaction.In comparison with "pre-cut", the authors coined the term "post-cut" to describe this technique.The feasibility, safety, and potential complications of post-cut were analyzed.Results: "Post-cut" was performed in consecutive10 cases of impacted biliary stone and an entrapped extraction basket when a therapeutic duodenoscope was used during the ERCP and allowed post-cut.The size of the removed stone ranged from 6mm to13mm.The length of post-cut 2 mm-4 mm.The impacted basket was easily retrieved in all patients without complications, including bleeding, perforation, and pancreatitis.Conclusions: "Post-cut" is a feasible, effective, efficient, and safe endoscopic technique when impaction of a biliary stone with an entrapped extraction basket develops.

食管纤维血管型息肉作为临床上较为少见的一种病变,具有增长快、并发症凶险、病人生活质量严重下降等临床特征.早期由于诊断技术的落后而被忽视,近年来由于技术的不断进步,该病变的诊断率也不断提高.依靠先进的检查手段,可以明确其临床及病理特点.目前,手术治疗、内镜介入等是食管纤维血管型息肉的主要治疗手段,应在术前及术后准确给予病变明确诊断,正确根据其病变特制定适当的个体化治疗方案,以提高患者的生活质量.
目的:探讨三腔二囊管在辅助急诊内镜下组织胶注射术联合硬化剂注射、静脉曲张套扎治疗食管胃底静脉曲张破裂出血的作用.方法:按就诊先后顺序选择60例患者,并采用单盲随机法分为研究组及对照组各30例,研究组运用三腔二囊管辅助急诊内镜下组织胶注射术联合硬化剂注射、静脉曲张套扎治疗食管胃底静脉曲张破裂出血,对照组运用常规急诊内镜下组织胶注射术联合硬化剂注射、静脉曲张套扎治疗食管胃底静脉曲张破裂出血,对两组疗效
食道鳞状细胞癌是中国最为常见的肿瘤之一.食道癌胃转移发生率较低,既往国内文献报道为0.2％,诊治一例以胃底粘膜下肿瘤就诊,最终手术证实为胃鳞状细胞癌的病例,当内镜发现胃底明显的粘膜下肿瘤时，在未确诊为间质瘤之前，不能排除其为鳞状细胞癌的可能。因此食道的观察需仔细，必要时需卢戈氏液染色，排除食道癌的可能。对食道癌的观察，即使是早期食道癌，如果在胃底、胃体上段发现可疑的粘膜下隆起，需进一步检查，排除鳞
急性胰腺炎(Acute pancreatitis,AP)是一种由多种病因引起胰酶异常分泌增加,在胰腺内被激活后导致胰腺组织自身消化甚至坏死的炎症反应.成年人发病率较儿童发病率高,病因主要为胆石症、酗酒、高脂血症等.儿童胰腺炎病因与成年人多有不同,本文对部分国内已发表的儿童急性胰腺炎病例进行总结、归纳,对于中国儿童胰腺炎发病原因进行综述.
胆石症是中国常见的一类外科疾病,它是引起腹痛的常见原因,在大于70岁的人群中约有30％患有胆囊结石.根据国内外研究显示,胆石症可占到胆道外科疾病的2.36％～42％,胆囊结石同时合并胆总管结石的患者占胆石症患者的5％～29％.胆囊结石与胆管结石常常互为因果,10％～15％的胆囊结石患者最终可能会出现胆总管结石.对于胆囊结石合并胆总管结石的患者,传统胆囊结石合并胆总管结石的治疗方法为开腹行胆囊切除、

背景 相对于胃肠镜而言,ERCP耗时较长,患者配合度较差,从而使部分患者舒适性差、满意度低、甚至无法顺利完成ERCP.近年来,国外对照研究表明全身麻醉下行ERCP能够提高患者的舒适度,提高ERCP的成功率,同时其安全性也与常规的镇静操作无显著性差异.我院自2015年4月开展无痛ERCP以来,目前已积累了一定的经验,本文采用回顾性分析的方法评价无痛ERCP的安全性.方法 收集2016年1月-8月ER
