Objective The examination of barium enema ever since 1905,colonoscope occurrence,it is very development to diagnose in small nonpolypoid lesion of large bowel.

中国诺宇综合网http：//www.siaaa.com 目的 1905年首次钡灌肠X线检查被用于临床诊断大肠病变以来，大肠镜的问世，为提高早期大肠癌的诊断和治疗，提供了最简便、最安全、最有效的方法。

Results: The positive rate of angiography, radionuclide scanning, double intestinal air-barium contrast examination, enteroscope, exploratory laparotomy and intraoperative colonoscopy...

小肠出血的诊断首选选择性肠系膜动脉造影；再行核素扫描，尤其是少量小肠出血对核素扫描较敏感；小肠气钡双重造影对小肠微小的隆起和凹陷性病变诊断价值较高；小肠镜的技术有待进一步提高；剖腹探查用于上述辅助检查均未能明确，且排除了上消化道和大肠病变而又有大量出血和反复出血者。应将小肠认为是中消化道而大肠是下消化道。
