摘要
AIM： To assess the role of retrograde terminal ileoscopy in hematochezia patients with normal colonoscopy. METHODS： Between January 1997 and March 2005, 39 hematochezia patients （males 36, females 3, mean age 44.7 years） with a reported normal colonoscopy underwent a repeat colonoscopy. After reaching the cecum, attempt was made to localize the ileocecal valve and intubate the terminal ileum. Any abnormality in the mucosa of the terminal ileum was carefully recorded and biopsies were obtained from suspiciouslooking lesions. RESULTS： During the study period there were 39 patients admitted for hematochezia in whom colonoscopy till cecum did not reveal any abnormality. Fulllength colonoscopy till the cecum could be performed in all the patients. The terminal ileum could be intubated in 36 patients. No abnormality was noted in 31 patients. Ileal ulcers were noted in two patients. Noclularity along with ulceration of the ileal mucosa, a Dieulafoy＇s lesion, and an angiomatous malformation were noted in one patient each. Histological examination of the biopsies obtained from the ulcers revealed typical tuberculous lesion in the patient with nodularity and ulceration. One of the patients had typhoid ulcers and another had non-specific ulcers. CONCLUSION： Retrograde terminal ileoscopy gives limited but valuable information, in patients with hematochezia and should be attempted in all such patients.
瞄准：估计角色后退在有正常结肠镜检查的便血病人的终端 ileoscopy。方法：在 1997 年 1 月和 2005 年 3 月之间， 39 个便血病人(男性 36，女性 3，意味着年龄 44.7 年) 与报导正常，结肠镜检查经历了重复结肠镜检查。在到达盲肠以后，被尝试本地化回盲肠阀门和 intubate 终端回肠。在终端回肠的粘膜的任何反常小心地被记录，活体检视从看似可疑的损害被获得。结果：在学习时期期间，有 39 个病人，为结肠镜检查没在揭示任何反常到盲肠为止的便血招收。全身的结肠镜检查能在所有病人被执行到盲肠为止。终端回肠能在 36 个病人被把管子插进。没有反常在 31 个病人被注意。回肠溃疡在二个病人被注意。与 i 的溃疡一起的 Nodularity 忠实粘膜， Dieulafoy 的损害，和血管瘤的畸形性各在一个病人被注意。从溃疡获得的活体检视的组织学的检查与 nodularity 和溃疡在病人揭示了典型有结节的损害。病人之一有伤寒的溃疡，另外一个有非特定的溃疡。结论：后退终端 ileoscopy 给有限却珍贵的信息，在有便血的病人并且应该在所有被尝试如此的病人。
