目的:评价双气囊电子内镜(DBE)在诊断小肠间质瘤中的价值,并比较DBE结果与多层螺旋CT小肠造影法(MSCTE)。方法:对2003年7月至2007年1月收治的62例经DBE检查确诊为小肠间质瘤患者的临床及病理资料进行回顾分析。结果:小肠间质瘤患者的主要临床表现为消化道出血、腹痛、腹部肿块和不完全小肠梗阻。62例小肠间质瘤患者中,原发于十二指肠者6例,空肠34例,回肠22例;发生远处转移者4例。58例局限性小肠间质瘤中,极低度危险者1例,低度危险者49例,中度危险者3例,高度危险者5例。62例患者经DBE检查诊断为小肠间质瘤57例,诊断率达91.9%;23例行多层螺旋CT小肠造影法(MSCTE)检查,诊断为小肠间质瘤20例,诊断率达87.0%。58例局限性病变患者手术完全切除后平均随访18个月,有2例患者复发,其中1例死亡。结论:DBE和MSCTE对小肠间质瘤均有较高的诊断率,两者结合有助于小肠间质瘤的早期诊断。
Objective: To evaluate the value of dual balloon endoscopy (DBE) in the diagnosis of small intestinal stromal tumors and to compare the results of DBE and multislice CT small intestine angiography (MSCTE). Methods: The clinical and pathological data of 62 patients diagnosed as small intestinal stromal tumors by DBE were retrospectively analyzed from July 2003 to January 2007. Results: The main clinical manifestations of patients with small intestinal stromal tumors were gastrointestinal bleeding, abdominal pain, abdominal mass and incomplete intestinal obstruction. 62 cases of small intestinal stromal tumor patients, primary in the duodenum in 6 cases, jejunum in 34 cases, ileum in 22 cases; distant metastasis in 4 cases. Among the 58 cases of small intestinal stromal tumors, 1 was at very low risk, 49 were at low risk, 3 were at moderate risk, and 5 were at high risk. Sixty-two patients were diagnosed as intestinal stromal tumors by DBE in 57 cases, the diagnostic rate was 91.9%. Twenty-three cases were diagnosed as small intestinal stromal tumors by MSCTE, the diagnosis rate was 87.0% . Fifty-eight patients with localized lesions were followed up for a mean of 18 months after complete resection. Two patients relapsed and one died. Conclusion: Both DBE and MSCTE have a high diagnostic rate for small intestinal stromal tumors, and the combination of the two can contribute to the early diagnosis of small intestinal stromal tumors.
