十二指肠乳头部肿瘤的超声诊断价值

Value of Ultrasound in the Diagnosis of Duodenal Papilla Tumor

【目的】探讨十二指肠乳头部肿瘤的超声征象及其与临床病理的相关性。【方法】对14例常规经腹超声怀疑十二指肠乳头部肿瘤的患者的临床、病理及声像图特征进行分析。【结果】9例病理及胃镜证实十二指肠乳头部病变（7例恶性，2例潜在恶性），4例胆总管下段腺癌侵及十二指肠乳头及肠壁，1例十二指肠降部憩室。声像图特征：①以低回声多见，边界较模糊，无明显包膜；②形态多为不规则结节状；③病灶内可见偏心气体强回声，或周边可见肠气、肠壁蠕动。【结论】在经腹常规超声检查中十二指肠乳头部肿瘤有其影像特征，注意肿块与十二指肠肠壁的关系是诊断及鉴别诊断的要点。

[Objective]To explore the ultrasonic sign of duodenal papilla tumor and its correlation with the clinicopathological manifestations. [MethodslThe clinical and pathological data and ultrasonic features of 14 patients suspected of duodenal papilla tumor examined by transabdominal ultrasound were analyzed, [Results] Nine patients with duodenal lesions including 7 patients with malignant tumor and 2 patients with potential malignant tumor. Four patients were adenocarcinoma of distal common bile duct involved in duodenal papilla and intestinal wall. One patient was diverticula of the descending part of duodenum. The ultrasonographic features were mainly low echo of nodules, ilbdefined and no marked pseudocapsule. The shape was irregular nodule. Strong eccentric gas echo in lesions, bowel gas and intestinal peristalsis beside were seen. [Conclusion] Duo- denal papilla tumor by transabdominal ultrasound has the iconographic features. Paying attention to the rela- tionship between tumors and duodenal wall is the key point of diagnosis and differential diagnosis.
