摘　　要：目的：讨论十二指肠球部充盈缺损的诊断和鉴别诊断。方法：共１２例患者，均进行钡餐造影检查，其中６例进行ＣＴ检查。结果：分别对１２例球部充盈缺损的影像表现进行分析。其中包括球部异物２例；淋巴瘤２例；腺瘤４例；低分化腺癌、类癌、胃窦癌脱入球部、胃息肉脱入球部各１例。钡餐造影显示了１２个病变；ＣＴ检查的６例中，显示５个病变，其中１个漏诊因病变小于１０ｍｍ。结论：十二指肠球部充盈缺损少见，钡餐造影对发现球部病变的大小、形态及腔内结构有重要作用，ＣＴ在病灶的性质病灶周围情况。Purpose:To discuss disagnosis and differential diagnosis of filling defect of duodenal bulb.Methods:In 12 patients with filling defect of duodenal bubl,All patients were performed with barium gastrointestinal,6 patients with CT.All cases were confirmed histological.Results:All patients images filling defect of duodennal bulb were analysed respectively.included:stomach stone in duodenal bulb(n=2);1yphoma (n=2);adenoma(n=4);low grade adenocarcinoma(n=1);carcinold(n=1);carcinoma of gastric antrum protrude into duodenal bulb(n=1);polyp of gastric antrum protrude into duodenal bulb(n=1).Barium gastro intestinal showed all lesion.CT showed 5 lesions,1 lesion was missed because lesion was less 10mm.Conclusion:Filling defect of duodenal bulb is rare,Barium gastrointestinal study is important to finding size and location of lesion and intraduodenal structure.CT may have significant impact on intramural or extraluminal extent and invasion of adjacent structures and distant metastasis.
