Endoscopic ultrasonography and small‐bowel endoscopy: Present and future

Over the last decade, impressive technological advances have occurred in ultrasonography and small‐bowel endoscopy. Nowadays, endoscopic ultrasonography is an essential diagnostic tool and a therapeutic weapon for pancreatobiliary disorders. Capsule endoscopy and device‐assisted enteroscopy have quickly become the reference standard for the diagnosis of small‐bowel luminal diseases, thereby leading to radical changes in diagnostic and therapeutic pathways. We herein provide an up‐to‐date overview of the latest advances in endoscopic ultrasonography and small‐bowel endoscopy, focusing on the emerging paradigms and technological innovations that might improve clinical practice in the near future.     

双球囊与缩宫素用于促宫颈成熟以及引产的效果比较

目的比较双球囊与缩宫素用于促宫颈成熟并引产的临床效果。方法选取于2017年7月—2018年7月在本院分娩的足月妊娠孕妇100例为研究对象,随机平均分为观察组和对照组各50例,观察组采用双球囊引产,对照组采用缩宫素进行引产,对比2组孕妇的总产程、宫颈成熟度、引产成功率和新生儿Apgar评分、并发症发生率等。结果观察组促宫颈成熟有效率(100%)、引产成功率(96%)均高于对照组(82%,74%),差异均有统计学意义(P<0.05),治疗后新生儿Apgar评分、并发症发生率差异均无统计学意义(P>0.05);宫颈Bishop评分观察组(9.12±1.42)高于对照组(7.92±1.56),观察组总产程(8.23±2.54)h,对照组(13.45±3.77)h,差异均有统计学意义(P<0.05)。结论双球囊用于妊娠引产效果显著,能明显促进宫颈成熟、缩短产程,保障分娩的顺利进行,安全可靠,值得在临床中推广。     

球囊导管取栓术治疗急性下肢动脉栓塞患者的体会

目的探讨球囊导管取栓术治疗急性下肢动脉栓塞患者的临床疗效。方法回顾性分析祈福医院2013年1月至2018年12月应用球囊导管微创取栓术治疗的78例急性下肢动脉栓塞患者的临床资料。结果治愈60例,治愈率为89.6%,患肢血供恢复。好转7例(10.4%),肢体缺血症状明显好转。全部患者无截肢。死亡1例(2.6%)。结论球囊导管取栓术是治疗急性动脉栓塞的有效方法,患者一经确诊应尽早手术取栓,有利于提高其保肢率和降低病死率。

Long-term results in the treatment of menorrhagia and hypermenorrhea with a thermal balloon endometrial ablation technique.

BACKGROUND AND OBJECTIVES: Evaluation of long-term results using a thermal balloon endometrial ablation technique to treat menorrhagia and hypermenorrhea, considered dysfunctional uterine bleedings. METHODS: A single-arm, prospective study with long-term follow-up of 48 months at the department of obstetrics and gynecology, University of Kiel, Germany. Following hysteroscopic evaluation of the uterine cavity and fractionated curettage, the Cavaterm endometrial thermal ablation technique was performed on 70 patients over the age of 40 with menorrhagia and hypermenorrhea in whom medical treatment had previously failed. The study included a group of 10 patients with adenomyosis and uterine fibroids. RESULTS: In 65 patients, a complete 48-month follow-up evaluation was possible: 58% of patients reported amenorrhea and 33% hypomenorrhea. Nine percent of patients remained eumenorrheic. Fifty percent of the small group with failed indications for the procedure had to undergo a hysterectomy. CONCLUSIONS: The Cavaterm thermal coagulation system in the earlier mode of application (15 minutes at a temperature of 70 degrees C and a pressure of 200 mm Hg) is a safe and highly effective method of endometrial ablation resulting in a minimal amount of posttreatment menstrual bleeding.     

留置超滑乳胶气囊导尿管并发症的原因分析及对策

目的探讨留置超滑乳胶气囊导尿管并发症的原因及对策。方法对586例留置超滑乳胶气囊导尿管患者进行观察,回顾分析。结果留置超滑导尿管并发症与导尿方法、规范操作、留置导尿管的时间及相关知识宣教有关。结论严格无菌操作,选择合适的导尿管、缩短留置尿管的时间是降低并发症的重要措施。     

Successful treatment with balloon dilatation using a double‐balloon enteroscope for a stricture in the small bowel of a patient with Crohn's disease

The requirement for endoscopic access to a stricture is a major limitation of the endoscopic dilatation for the treatment of strictures in the gastrointestinal tract. We have developed the double‐balloon enteroscopy method that enables visualization of the entire small bowel. In addition, double‐balloon enteroscopy has a potential for the interventional therapy including dilatation of strictures. We present here a case of jejunal strictures in a 47‐year‐old woman with Crohn's disease successfully treated with a balloon catheter in combination with double‐balloon enteroscopy. Balloon dilation with double‐balloon enteroscopy is a promising method for the treatment of small bowel strictures in Crohn's disease.     

介入法制作犬颅内动脉瘤模型

目的运用介入方法建立犬颅内动脉分叉部囊状动脉瘤模型。方法6条犬全麻后，采用血管内介入方法，用冠状动脉球囊导管扩张右颈总动脉近段，再用可脱球囊于扩张段远端将其栓塞，制作成6个分叉部动脉瘤。分别于术后1、2、3d行DSA检查并切除动脉瘤做病理组织学检查。结果6条犬成功获得6个动脉瘤模型。动脉瘤的平均宽度和平均长度在3d内逐渐减少。结论犬动脉瘤模型较好地模拟了人颅内动脉瘤大小、形态及DSA表现，可用于介入治疗新材料、新技术的实验研究。本动脉瘤模型的建立快速、可靠、可重复性强。
