十二指肠球部及降部隆起性病变的内镜分析及临床意义

目的通过对十二指肠球部及降部的隆起性病变的内镜分析,提高人们对该病变的认识。方法经电子胃镜、十二指肠镜、超声内镜、ERCP等检查方法,共检出十二指肠球部及降部的隆起性病变1 187例,对其进行内镜分析。结果本组十二指肠球部及降部隆起性病变共1 187例,其中息肉981例,恶性肿瘤69例,间质瘤53例,异位胰腺31例,囊肿27例,脂肪瘤26例,所占比例分别为82.65%、5.81%、4.47%、2.61%、2.27%、2.19%。981例息肉中,经病理证实肿瘤性息肉137例,占13.97%(137/981)。60 748例上消化道内镜检查中恶性肿瘤69例,其发生率为0.11%(69/60 748)。结论十二指肠球部及降部隆起性病变中息肉最为常见,其中肿瘤性息肉所占比例远高于文献报道,恶性肿瘤的发生率也较以前增加,人们应提高对十二指肠球部及降部隆起性病变的警惕。

The endoscopic analysis and clinical significance of the protrusion lesions in duodenal ball and descendant duodenum

Objective The protrusion lesions of duodenal ball and descendant duodenum were analyzed through endoscope signs in order to raise awareness of this lesion.Methods Through electronic gastroscope,duodenoscope,echogatstroscope and ERCP,1 187 cases of the protrusion lesions in duodenal ball and descendant duodenum were detected and analyzed.Results The total number of upper gastrointestinal endoscopy were 60 748 in our digestive endoscopy center nearly 3 years.From these cases,the total number of the protrusion lesions in duodenal ball and descendant duodenum were 1 187.Among them,981 cases were polypi(82.65%).69 cases were malignant tumor(5.81%).53 cases were interstitialoma(4.47%).31 cases were heterotopic pancreas(2.61%).27 cases were cyst(2.27%) and 26 cases were liparomphalus(2.19%).Among 981 cases of polypi,adenomatous polyp were 137 cases which had confirmed through pathology.The proportionate morbidity rate of malignant tumor was 0.11%.Conclusion Polypi are the most among the protrusion lesions of duodenal ball and descendant duodenum.The proportionate morbidity rate of adenomatous polypi and malignant tumor is far higher than reported.We should be vigilant to the protrusion lesions in duodenal ball and descendant duodenum.
