Clinical Analysis Of Small Intestinal Vascular Malormation In 22 Cases

Objectives:To explore the clinical feature and examination methods of small intestinal vascular malformation, increase the knowledge and improve the diagnostic rate. Methods:Retrospectively analyze 22 cases of small intestinal vascular malformation about their major symptoms, predilection site and diagnostic methods, which were treated in our hospital from 2008.1-2011.2. Results:In 54 patients with small intestinal hemorrhage 25(46.30%) were small intestinal tumor, of which 18 were interstitialoma (33.33%),adenoma(3.70%), adenocarcinoma (1.85%), lymphoma (1.85%),leiomyoma (1.85%),fibroma (1.85%), liparomphalus (1.85%),others 22 were vascular malformation(40.74%), ulcer (5.56%), diverticulum (1.85%), Crohn disease(1.85%). In 22 patients with small intestinal vascular malformation,the patient's age ranged from 26 to 80 years,with an average age of 60.32±14.22 years.The ratio of male and female was almost equal.The course of disease from 4days to 18 years, with an average course of 30.62 months. The predominant haemorrhage symptoms were either melena or tarry stool.The predilection site of small intestinal vascular malformation was no specificity. All of above, there were no difference between vascular malformation and non-vascular malformation (P>0.05),but the symptoms like abdominal pain,diarrhea,abdominal mass were normal accured in non-vascular malformation (P<0.05). Among these vascular malformation patients, capsule endoscopy and DSA was the major diagnostic methods, obviously higher than Gastrointestinal barium meal examination(P<0.01) and CT (P<0.05).The rate of surgical operation of vascular malformation is lower than non-vascular malformation(P<0.01).Conclusion:One of common reasons lead to small intestinal hemorrhage is small intestinal vascular malformation,which almost happened in old people, and the ratio of male is a little more than female. There was no specificity clinical manifestations and signs in small intestinal vascular malformation. The predilection site of small intestinal vascular malformation was no specificity. Capsule endoscopy and DSA was the major diagnostic methods. The rate of surgical operation of vascular malformation is very low.
