CURRENT STATUS OF DOUBLE BALLOON ENDOSCOPY

Yamamoto and colleagues have developed a novel insertion method of the endoscope, the ‘double balloon method’ for enteroscopy and, recently, a specialized system for the ‘double balloon method’ has been commercialized by Fujinon. The double balloon endoscopy enables visualization of the entire small bowel and also allows for interventional therapy in the small intestine. This method could be used either from the oral or anal approach. Observation of an affected area with controlled movement of the endoscope enables interventions, including biopsies, hemostasis, balloon dilatation, stent placement, polypectomy, and endoscopic mucosal resection. The procedure is safe and useful, and it provides high diagnostic yields and therapeutic capabilities.     

Detailed Analysis of Mucosal Restoration of the Small Intestine After the Cavitary Two-Layer Cold Storage Method

Small bowel transplantation (SBT) is associated with a high incidence of infectious complications because of ischemia/reperfusion (I/R) mucosal injury concomitant with potent immunosuppression. In this study, we evaluated whether the cavitary two-layer method (cTLM) could reduce I/R injury and allow early mucosal restoration, particularly after prolonged preservation and transplantation. Canine heterotopic segmental SBT was performed immediately without preservation (group 1), after 24-h preservation in UW solution (group 2) or by the cTLM (group 3). The graft samples were taken 1 h after reperfusion and on days 1, 4 and 7. We assessed graft mucosa with detailed microscopic and electromicroscopic analyses. In Group 3, histological injury and cell apoptosis after transplantation were significantly alleviated and rapidly recovered to a similar level of group 1. The mucosal restoration was morphologically completed within 4 days. In contrast, in group 2, more pronounced mucosal injury and delayed recovery were noted. Crypt cell proliferation activity was well maintained in groups 1 and 3 throughout the experimental period. Our ultrastructural analysis suggested that mitochondrial integrity achieved by the cTLM was a basal mechanism under the prompt mucosal restoration. The cTLM could reduce I/R injury, facilitate mucosal regeneration and restore the nearly normal structure early after SBT.     

微小切口胆囊切除术2260例效果观察

目的 总结微小切口胆囊切除术治疗胆道系统疾病的经验。方法 对2002-2004年连续收治的2260例胆囊、胆道系统疾病实施微小切口手术的临床观察资料进行回顾性分析。结果 本组2260例微小切口胆囊切除术的患者无一例因手术原因死亡；术后无残留小胆囊；无胆汁漏及腹腔脓肿，亦无伤口全层裂开及切口疝形成。结论 该术式损伤小、局部显露清楚、不易发生副损伤，可同时行胆总管探查术，特殊情况下可随时改变手术方式。     

永磁速愈贴对妇产科手术切口愈合的观察

目的探讨永磁速愈贴对切13的消肿止痛，促进伤口愈合和防止疤痕粘连与普通敷料进行对比观察。方法将住院行妇产科手术100例患者与同期住院的手术患者进行对比观察。结果永磁速愈贴切13愈合佳者84．0％，良好者13．0％，愈合差为3．0％，而普通敷料为28．0％、60．0％和12．0％，p〈0．01（x^2=63．660）。结论永磁速愈贴切口具有透气、保湿、促进伤口愈合、消肿、止痒，防止疤痕形成等作用。而普通敷料透气性差，保湿性差，术后切口有红肿、缝线反应、切口愈合时间长及切口局部愈合后有痛痒感。     

螺旋CT在小肾癌诊断中的价值

目的评价螺旋CT多期扫描在小肾癌诊断中的价值。方法收集经手术病理证实的小肾癌14例,分析其螺旋CT平扫、皮质期、实质期及肾盂期的表现。结果CT平扫病灶呈等密度7例,稍低密度5例,稍高密度1例,1例为囊实性肿块,其中2例伴斑点状钙化。增强扫描皮质期12例呈明显强化,2例呈轻中度强化。肾实质期肿瘤密度迅速减退,肾盂期肿瘤密度进一步减退。结论小肾癌螺旋CT增强多期扫描征象有一定特征性,对小肾癌的诊断有重要价值。
