大鼠大网膜蒂瓣小肠延长术及延长肠段的蠕动功能

A staged bowel elongation technique usingomentum as vascular flap──An experimen-tal study

采用分期手术建立大网膜为蒂瓣的小肠延长实验模型，术后６周检测延长肠段的蠕动功能。结果显示延长肠段与正常对照肠段具有相似的自动节律性收缩功能，为进一步研究该技术治疗短肠综合征提供了有用的资料。

Using staged surgical approach.a newbowel elongation model in rats was developed.The procedure consists of:①initial enteropexybetween the margin of the omentum and theantimesenteric border of jejunum and ② sec-ondary longitudinal split of the jejunum aftercollaterals have developed 30 days later,toprovide two bowel loops,and then end to endanastomosis to double the original jejunallength. Six weeks later, the elongated jejunumand control bowel segments were evaluated by using transducer. This preliminary study demonstrated that the moter function was pre-served in the elongated jejunum. It is suggest-ed that staged bowel elongation technique us-ing omentum as vascular flap can be used toprovide functioning bowel for the trcatment ofshort bowel syndrome.
