摘要
目的分析小肠间质瘤并发消化道出血的临床、影象及病理特点，提高小肠出血的确诊率。方法对我院1990年1月-2007年2月手术确诊的23例小肠间质瘤患者的临床资料进行回顾性分析，结合文献总结小肠间质瘤并发消化道出血的临床特点，分析腹部CT、小肠气钡造影、血管造影、双气囊小肠镜对小肠间质瘤的检出率。结果手术确诊的23例小肠间质瘤患者中，有15例（65．2％）并发消化道出血，其中男11例，女4例，平均年龄50．2岁（38-69岁），血红蛋白中位数为57g／L，60％的患者曾接受输血治疗；腹部CT检出率为69．2％（9／13），小肠气钡造影率为77．8％（7／9），血管造影为88．9％（7／8），小肠镜为100％（8／8）；15例并发出血的小肠间质瘤患者黏膜面均有溃疡形成，间质瘤直径中位数为3．5cm，85％的间质瘤直径≤5．0cm；良性5例，低度恶性8例，恶性2例；另8例无并发出血间质瘤直径的中位数为8．4cm，均为恶性间质瘤。结论小肠间质瘤并发消化道累积出血量较大，多表现为反复出血；双气囊小肠镜和血管造影较腹部检查CT敏感，尤其对于直径≤2．5cm的间质瘤。
Objective To analyze and determine the clinical characteristics and diagnosis of alimentary tract hemorrhage of stromal tumor in small intestine. Methods We reviewed the medical records of all 23 patients who were diagnosed with stromal tumor in small intestine in Peking Friendship Hospital from 1990 to 2007. Results Of 23 patients （ 12 male, 10 female, median age 50.2 years; average Hb 5. 7g/dl） with stromal tumor in small intestine diagnosed by CT （69.2%）, GI （77.8%） , DSA （88.9%） and double balloon enterscopy （ 100% ）, 15 patients had alimentary tract hemorrhage;Pathological results： All 15 stromal tumors of small intestine accompanied ulceration on mucosa, average diameter 3.5 cm ,5 benign cacses,8 cases of low potential malignancy and 2 cases of malignancy, the other 8 cases with stromal tumors without hemarrage were malignant The average diameter of stromal tumors was 8.4 cm. Conclusion Alimentary tract hemorrhage of stromal tumor in small intestine often occurrs and is repeated several times;Angiography is more sensitive for small stromal tumor （average diameter≤2.5cm） than CT.
