At the root canal therapy process, hidden in the root canal isthmus, bifurcation area, triangle, shape and irregular dentinal tubules within the Enterococcus faecalis prepared by mechanical means it is difficult to remove, it can be biofilm, proton pump tolerance mechanisms such as root canals harsh ecological environment, to avoid conventional drugs, the role of disinfection, resulting in the failure of root canal therapy.

在根管治疗过程中，隐藏在根管峡部、分叉区、三角区、形态不规则区及牙本质小管内的粪肠球菌难以用机械预备的方法去除，它可通过生物膜、质子泵等机制耐受根管内苛刻的生态环境，躲避常规消毒药物的作用，从而导致根管治疗的失败。

Abstract］ objective to explore the experience in the diagnosis and treatment of small bowel diverticular surgical complication.methods 24 cases of small bowel diverticular were retrospectively analysed.results the diagnosis was made preoperatively in 4 duodenal diverticula and only 1 jejunal diverticula.clinical complications included obstruction in 11 cases,bleeding in 4 cases,perforation in 4 cases.23 cases were cured.1 case was died of mof.all the diverticular with complications had histopathological signs of inflammation and 3 had signs of ulcer and 4 had the resected.conclusion the small bowel diverticular is rare.it may diagnose except common reason underwent gastrointestinal bleeding or obstruction.the gi is an effective way of examinations.operation is effective for small bowel diverticular disease.

回顾性分析24例小肠憩室病外科并发症的临床资料。结果术前6例十二指肠憩室中4例确诊，18例空回肠憩室仅1例确诊。小肠憩室伴小肠梗阻11例，憩室出血4例，憩室穿孔4例。23例治愈，1例死于多脏器功能衰竭。有并发症的憩室病理都有炎症表现，5例有溃疡，4例有异位黏膜组织。结论小肠憩室病比较少见。在胃肠出血或梗阻的情况下，可采取对常见原因排除的方法进行诊断。在不需要急诊手术的情况下，钡餐造影是最有效的检查。手术是可靠有效的治疗方法。

We propose that the noncell-autonomous effects of Spemann's organizer on dorsoventral patterning are executed in part by diffusible signals that directly bind to and neutralize ventral BMPs during gastrulation.
