十二指肠降部螺旋CT表现在壶腹周围癌诊断中的价值

Spiral CT imaging of descending part of duodenum : role in diagnosis of peri-ampullaris carcinoma

病例组与对照组均在ERCP检查时于十二指肠降部Vater，壶腹远端2～3cm处取活检。

All patients underwent an ERCP , biopsies were obtained from the second part of the duodenum distal to the ampulla of Vater .

原发性十二指肠降部中及低分化腺癌行胰十二指肠切除术各1例；

For the descending portion of the duodenum , 1 case of moderately-differentiated and1 poorly-differentiated carcinoma received pancreatoduodenectomy .

肿瘤位于十二指肠降部者11例，占50%。

The location of the tumors in 11 cases ( 50 % ) was at the second part of duodenum .

平均发病时间3.4个月。肿瘤位于十二指肠降部者11例，其中腺癌10例，平滑肌肉瘤1例，位于横部者1例，为腺癌。

Eleven patients had tumor locating in second portion of duodenum , 10 cases of adenocarcinoma and 1 case of leiomysarcoma .

损伤部位以十二指肠降部及降部与水平部交界处为多见，有12例，占75%。

Injuries of discending part and border between discending part and level part were found in 12 of 16 patient ( 75 % ) .

肿瘤好发于十二指肠降部，共45例，另外球部4例，水平部4例，升部0例，病理类型以腺癌为主，占90.5%。

The tumor was predilection in the descending part of the duodenum , 45 cases , while 4 in bulbar zone , 4 in the horizontal part and none in the ascending part . The main pathological type is adenocarcinoma , 90.5 % .

在基线时H.pylori阳性组病人胃体和胃窦的嗜酸性粒细胞计数均较H.pylori阴性组明显升高，而在十二指肠球部和十二指肠降部两组间的嗜酸性粒细胞水平无显著差异。

In the baseline level , the eosinophil counts of body and antrum were significantly increased in the H.pylori-positive group vs the H.pylori-negative group .

结论急性荨麻疹患儿大部分有胃镜下改变，且以十二指肠球-降交界部黏膜损害最多见。

[ Conclusion ] The gastroscopic and histologic mucosal changes were found in most acute urticaria with gastroduodenal tract lesions ;

结果十二指肠损伤合并其他腹部脏器损伤占81%，十二指肠降部损伤占50%，水平部占27.5%。

Lower location of injury was 50 % , and horizontal location was 27.5 % .
