摘要
目的探讨直肠类癌的内镜超声(EUS)图像特征,以提高其诊断正确率。方法连续收集2001年4月至2004年4月直肠黏膜及黏膜下肿物29例,行EUS检查及病理检查,分析经病理确诊的直肠类癌的EUS图像,找出其特征性表现。结果29例共检出病灶29个,其中类癌12个,腺瘤11个,炎性病灶6个。直肠类癌病灶中10个呈低回声结节,2个呈等回声;5个病灶位于黏膜层,7个位于黏膜下层;12个病灶边界均清晰。结论直肠类癌的EUS声像图特征是:病灶边界清,回声均匀,位于黏膜下层或黏膜层,绝大多数呈低回声结节。EUS声像图特征有助于直肠类癌的早期诊断。
Objective In order to improve the diagnostic accuracy for rectal carcinoid, features of endoscopic ultrasonography ( EUS) in rectal carcinoid were studied. Methods Twenty-nine consecutive ca-ses of rectal mucosal or submucosal mass were collected. EUS and pathologic examinations were performed. EUS images of rectal carcinoid confirmed by pathology were analyzed to find out their characteristic features. Results A total of 29 regions of interest ( ROIs) were detected in 29 patients, including 12 carcinoid le-sions, 11 adenomatous and 6 inflammatory lesions. Ten of the 12 rectal carcinoid lesions were hypoechoic, and the rest isoechoic; five of them were mucosal and 7 submucosallesions; all of the 12 lesions had well de-fined boundaries. Conclusion The characteristic features of EUS images of rectal carcinoids include well-defined boundary, homogeneous echo in submucosa or mucosa, and most of them are hypoechoic nodules. These EUS characteristic features greatly facilitate the early diagnosis of rectal carcinoid.
