16层螺旋CT诊断Lemmel’s综合征的临床价值

MSCT value in the diagnosis of Lemmel's syndrome

目的探讨16层螺旋CT对lemmel’s综合征(十二指肠乳头旁憩室)的诊断价值。方法对经MSCT检查确诊的20例十二指肠乳头旁憩室患者的影像资料进行回顾性分析。结果 20例患者共发现十二指肠乳头旁憩室20个,其中17个憩室壁菲薄,3个憩室壁较厚,憩室大小10～45mm,十二指肠乳头旁憩室表现为十二指肠圈内侧缘呈囊状突出于十二指肠小弯侧壁,其内多为气体密度影,内见气-液平面6例,增强扫描所示憩室壁强化与十二指肠壁强化一致,腔内无强化。20例病例胆管系统均可见不同程度的扩张,多平面重组及三维重组可以清楚的显示憩室与十二指肠及十二指肠乳头的毗邻关系。结论 16层螺旋CT对Lemmel’s综合征的诊断具有较高的准确性,对本病的诊断具有重要价值。

Objective To study the MSCT value in the diagnosis of Lemmel＇s syndrome （Juxtapapillary duodenal diver- ticulum）. Methods The image data of patients with Lemmel ＇s syndrome diagnosed with MSCT were analyzed retrospec- tively. Results In total, 20 duodenal nipple diverticula were found in 20 patients near, of which 17 diverticula presented with thinner wall, 3 with thicker walls, with sizes of 10~45 mm. The duodenal performance presented with duodenal di- verticula nipple ring inside edge that appeared cystic outstanding on amazon duodenal wall, in which the density of the gas shadow can be seen and thevisible gas-liquid plane was found in 6 cases. The enhanced scan showed diverticula wall rein- forcement and the duodenal wall aggrandizement was consistent, without any enhancement inside the cavity. In these 20 cases, the bile duct system appeared expansion in different degree. Reconstruction and reorganization in 3 D plane can clearly display diverticula and the relations of duodenum and duodenal nipple to adjacent tissues. Conclusion MSCT has high accuracy in the diagnosis of Lemmel＇s syndrome, thereby possessing the important value in diagnosis of this disorder.
