目的 :对可切除的原发性十二指肠恶性肿瘤X线征象进行分析。方法 :对 2 6例原发性十二指肠恶性肿瘤胃肠道造影及CT征象进行了回顾性对比分析总结。结果 :全部病例均经手术病理证实 ,其中腺癌 2 2例 ,平滑肌肉瘤 3例 ,非何杰金氏淋巴瘤 1例。描述包括肿瘤的部位 ,造影X线表现 (黏膜破坏 ,充盈缺损及龛影 ,管腔不规则狭窄 ,肠腔外改变等 )及CT表现 (肠壁增厚肠腔狭窄 ,局部肿块 ,梗阻性改变及转移 )。不能手术切除的影像学征象为 :肿瘤直径大于 6cm ;腹腔、系膜淋巴结成团肿大 ;腔静脉、肠系膜动静脉等重要血管管径被包绕大于 2 / 3时。结论 :CT与X线造影对肿瘤的位置、大小、形态 ,肿瘤的继发征象的术前评价 ,能够提供能否手术切除的重要依据。
Objective: To analyze the X-ray findings of resectable primary duodenal malignancies. Methods: A retrospective comparative analysis of gastrointestinal and CT findings of 26 patients with primary duodenal malignant tumors was performed. Results: All cases were confirmed by surgery and pathology, including 22 cases of adenocarcinoma, 3 cases of leiomyosarcoma and 1 case of non-Hodgkin’s lymphoma. Described include tumor site, radiographic X-ray findings (mucosal damage, filling defects and niche, irregular luminal stenosis, extraluminal changes, etc.) and CT findings (intestinal wall thickening of the stenosis, local mass, obstructive changes And transfer). Imaging signs of incapable resection are: tumor diameter greater than 6cm; abdominal cavity, mesangial lymphoid enlargement; vena cava, mesenteric artery and vein and other important vascular diameter is more than 2/3 when wrapped. Conclusion: The preoperative evaluation of the location, size, shape and secondary signs of tumor by CT and X-ray can provide an important basis for the surgical resection.
