小肠出血52例临床分析

Clinical Analysis of 52 Cases of Small Intestinal Bleeding

目的探讨小肠出血的病因、诊断和治疗方法。方法回顾性分析1999～2007年间经手术和病理证实的小肠出血52例的临床资料。结果小肠出血原因中小肠良性肿瘤占首位(33例),其次为小肠憩室(10例)、腺癌(6例)及血管畸形(3例);18例经小肠气钡双重造影确诊,16例经选择性肠系瞙上动脉造影确诊,6例经放射性核素扫描确诊,12例经剖腹探查确诊;52例均行手术治疗。结论小肠出血的主要诊断方法是小肠气钡双重造影、选择性肠系膜上动脉造影和放射性核素扫描;早期剖腹探查仍为目前最可靠的治疗手段。

Objective To investigate the causes,diagnostic methods and therapy of small intestinal bleeding. Methods 52 cases of small intestinal bleeding confirmed by surgery and pathology from 1999 to 2007 were retrospectively analyzed. Results Benign tmmus of small intestinal（33 cases） were the first cause of small intestinal bleeding, followed by diverticulum（10 cases）, ede^inoma（6 cases）and vascular malformation（3 cases）; 18 cases of small intestinal bleeding were diagnosed definitely by enteroclysis, 16 cases were diagnosed definitely by angiography,6 cases were diagnosed definitely by radionucleide scanning,12 cases were diagnosed definitely by exploratory laparotomy. Conclusion Enteroclysis,angiography and radionucleide scanning are the main diagnostic methods of small intestinal bleeding;early exploratory laparotomy is widely accepted as an effective treatment at present.
