目的 提高对胃良性肿瘤脱垂于十二指肠（球）的Ｘ线表现、机制、脱垂分型和鉴别诊断的认识。方法 回顾性分析和研究了采用钡餐胃肠道造影和胃镜检查，并经手术和病理证实的胃良性肿瘤脱垂十二指肠（球）８例。结果 胃良性肿瘤脱入十二指肠（球）的Ｘ线表现有：①十二指肠（球）的充盈缺损和十二指肠降段充盈缺损；②牵引粘膜桥征和幽门管增宽；③肿瘤表面粘膜显示光整和龛影－“牛眼征”；④胃整体形态的改变；⑤肿瘤脱垂与回纳现象；⑥原发肿瘤的部位分布：胃窦部肿瘤６例，胃体部和胃底部肿瘤各１例。病理诊断一脱委于十二指肠球内平滑肌瘤４例，脂肪瘤和神经鞘瘤各１例，脱垂于十二指肠降部平滑肌瘤２例。结论 可靠的Ｘ线诊断征象有：①十二指肠（球）的充盈缺损；②牵引粘膜桥征；③幽门管增宽；④胃整体形态的改变。
Objective To improve the understanding of X-ray appearance, mechanism, prolapse typing, and differential diagnosis of benign gastric tumour prolapse in the duodenum (ball). Methods Retrospectively analyzed and studied 8 cases of benign duodenal duodenum (ball) with gastric gastrointestinal angiography and gastroscopy confirmed by surgery and pathology. Results X-ray findings of benign gastric tumors in duodenum (ball) were as follows: 1 filling defect of duodenum (ball) and filling defect of descending duodenum; 2 traction mucosal bridge sign and widening of pylorus tube 3 The surface mucosa of the tumor showed smoothness and haze - “Bull’s eye sign”; 4 changes in the overall morphology of the stomach; 5 tumor prolapse and recoil; 6 distribution of the primary tumor: gastric antrum tumor in 6 cases, stomach There were 1 case of tumor in the body and bottom of the stomach. Pathological diagnosis of a dislocation in the duodenal leiomyoma in 4 cases, lipoma and schwannoma in 1 case, prolapse in duodenal descending leiomyoma in 2 cases. Conclusions Reliable X-ray diagnostic signs include: 1 filling defect of the duodenum (ball); 2 traction mucosal bridge sign; 3 widening of the pyloric tube; 4 changes in the overall shape of the stomach.
