Résumé
Objective To evaluate the etiology and clinical features of jejunoileum bleeding.Methods Seventy-two patients admitted in 7 hospitals of Shangdong province for jejunoileum bleeding from January 1998 to December 2008 were enrolled in the study. There were 46 males and 26 females with mean age of 47 years (ranged 13-85 years). The jejunoileum bleeding was confirmed by means of endoscopy, images or surgery. The causes, diagnostic methods and major clinical manifestations were retrospectively analyzed. Results The most frequent cause of jejunoileum bleeding was tumor (42/72,58.3 %), followed by enteritis (9/72, 12.5 %), diverticulum ( 7/72, 9. 7%), angiopathy (7/72,9.7%), Crohn's disease (3/72,4.2%). Differences were significant in constituent ratio of cause of jejunoileum hemorrhage between male and female and between jejunum and ileum (P＜0.05).Hematochezia or hematochezia with abdominal pain was the first presentation. The jejunoileum bleeding in 54. 2% patients was diagnosed by laparotomy, 23. 6% by capsule endoscopy, 9.7% by selective angiography, 6.9% by small bowel series and enteroclysis, 2.8% by colonoscopy and 2.8% by push enteroscopy. The complications of jejunoileum bleeding were anemia, intestinal obstruction,peritoneal metastasis, shock, ankylenteron and intestinal perforation. Conclusions Intestinal tumor is the most common cause in jejunoileum bleeding, especially in jejunum. Whereas the enteritis,diverticulum and angiopathy were often found in ileum. The capsule endoscopy and push enteroscopy are recommended in diagnosis of jejunoileum bleeding.
