Evaluation on double-balloon enteroscopy in the diagnosis of small intestinal tumor

摘要:

目的：评价双气囊电子内镜对诊断小肠肿瘤的价值。方法:运用双气囊电子内镜对2004年12月至2009年12月,253例不明原因消化道症状的患者进行检查。结果:检出82例小肠肿瘤,占本组病例32.41%,以消化道出血及腹痛、腹胀症状较多，而慢性腹泻、呕吐及不全性梗阻症状比例稍低。82例肿瘤患者中检出44例间质瘤,其中29例病理诊断为恶性；血管瘤12例；管状腺瘤8例；平滑肌瘤、B细胞性淋巴瘤各5例；平滑肌肉瘤3例；脂肪瘤、转移性黏液癌各2例；黑色素瘤1例。手术治疗患者中，部分患者术中再行全小肠检查，4例发现病灶为多发，占6.66%。结论:双气囊电子内镜可提高小肠肿瘤的病变诊断率。

Abstract:

Objective:To evaluate the value of double balloon endoscopy in the diagnosis of small intestinal tumors.Methods: Totally 253 patients with unexplained gastrointestinal symptoms from December 2004 to December 2009 were examined by double-balloon endoscopy.Results:Eighty-two (32.41%) cases were diagnosed as small intestinal tumor,most of which suffered from gastrointestinal bleeding,abdominal bloating and pain,fewer experienced the symptoms of chronic diarrhea,vomiting and incomplete obstruction.Of the 82 cases,there were 44 cases of stromal tumors with 29 cases being malignant,12 cases of vascular tumor,8 cases of tubular adenoma,5 cases of smooth muscle tumors,5 cases of B cell lymphoma,3 cases of leiomyosarcoma; 2 cases of fat tumor and metastatic mucinous carcinoma respectively and 1 case of melanoma.Re examination of the entire small intestine was performed on some cases during the surgery,four of which were found to have multiple lesions,accounting for 6.66%.Conclusion:Double balloon endoscopy can improve the diagnostic accuracy for small intestinal tumors.
