【摘要】：目的探討小腸腫瘤及腫瘤樣病變患者的病理特征及其CT表現(xiàn)。方法回顧性分析本院2013年2月-2016年2月經(jīng)手術(shù)病理證實(shí)的60例小腸腫瘤及腫瘤樣病變患者的臨床資料,比較觀察不同腫瘤、瘤樣病變病理特征及CT表現(xiàn)。結(jié)果病理檢查顯示60例患者中惡性腫瘤5例,良性腫瘤35例,腫瘤樣病變20例,均呈現(xiàn)息肉狀且往腸腔內(nèi)突出特點(diǎn);胃腸道間質(zhì)瘤病灶在黏膜下,梭形腫瘤細(xì)胞,排列走向不一;脂肪瘤也位于黏膜下,黏膜表面潰瘍,腫瘤切面黃色;淋巴組織增生鏡下顯示黏膜層存在病灶,細(xì)胞分化成熟。CT對小腸腫瘤、腫瘤樣病變檢出率均為90.00%,腺癌CT增強(qiáng)掃描呈現(xiàn)"快速上升-平臺"特點(diǎn);小腸淋巴瘤CT表現(xiàn)為腸壁增厚、腸管狹窄、腹膜及腸系膜淋巴結(jié)腫大;胃腸道間質(zhì)瘤以腔外生長為主,圓形或橢圓形,病灶與周邊正常腸壁邊界清楚。結(jié)論小腸腫瘤以良性腫瘤為主,病理特征、CT表現(xiàn)在小腸腫瘤及腫瘤樣病變診斷中有重要價(jià)值。
[Abstract]:Objective to investigate the pathological features and CT findings of small intestinal tumors and tumor-like lesions. Methods 60 cases of small intestinal tumors and tumors proved by surgery and pathology from February 2013 to 2016 were retrospectively analyzed. Clinical data of patients with like lesions. Results pathological examination showed that there were 5 cases of malignant tumor, 35 cases of benign tumor and 20 cases of tumor-like lesion. All of them showed polypoid and protruding into the lumen. Gastrointestinal stromal tumors (GIST) with submucous and fusiform tumor cells are arranged in different directions. Lipoma is also located in the submucous membrane, mucosal surface ulcer, tumor section yellow; Lymphoproliferative examination showed that there were lesions in mucosal layer. The detectable rate of tumor-like lesions was 90.00% for small intestinal tumors with mature cell differentiation. The CT enhanced scan of adenocarcinoma showed the characteristics of "rapid rise-platform". Ct findings of small intestinal lymphoma included thickening of intestinal wall, stenosis of intestinal duct and enlargement of peritoneal and mesenteric lymph nodes. Gastrointestinal stromal tumors (GIST) are mainly extraluminal, round or oval, and the boundary between the lesions and the surrounding normal intestinal wall is clear. Conclusion small intestinal tumors are mainly benign tumors, pathological characteristics. Ct findings are of great value in the diagnosis of small intestinal tumors and tumor-like lesions.

【正文快照】： 小腸具有長度長、走向曲折、活動度大特點(diǎn),因此小腸腫瘤臨床少見,在消化道腫瘤中僅占1%~4%[1]。大部分小腸腫瘤患者經(jīng)手術(shù)治療后早期治愈率高,為此早期診斷出小腸腫瘤對其治療方案制定、預(yù)后改善具有十分重要的意義[2]。由于小腸腫瘤早期癥狀無特異性,且X線、小腸鏡檢查對黏膜
