目的结合临床表现评价CT对十二指肠乳头旁憩室(JDD)的诊断价值。方法回顾性分析55例JDD(共56个)的临床表现和CT征象。结果在55例JDD中出现胆系疾病48例次,胰腺炎5例次。JDD最突出的CT征象是在十二指肠与胆总管下段之间的气泡影,可不伴有液平(32例)或伴液平(18例)。5例JDD腔内存留未消化食物及气体而成网格状影。仅1例JDD不含气,因有碘剂而被显示,JDD均位于十二指肠环内,根据与胆总管下段的关系,被分成居右(27个)、居前(15个)、居后(9个)及左下方(5个),除后者源于十二指肠水平段外,前三者均源于降段。CT在横断面上能很好显示JDD壁与胆胰管下段管壁的位置关系。结论 JDD可引起明显的胆胰管并发症,CT是诊断JDD非常实用而有效的影象学方法。
Objective To evaluate the diagnostic value of CT in the diagnosis of parathyroidectomy (JDD). Methods Retrospective analysis of 55 cases of JDD (a total of 56) clinical manifestations and CT signs. Results In 55 cases of JDD in 48 cases of gallbladder disease, pancreatitis in 5 cases. The most prominent CT sign of JDD was air bubble between the duodenum and the lower common bile duct, which was not associated with either level (32 cases) or with fluid level (18 cases). 5 cases of JDD cavity remain undigested food and gas into a grid-like shadow. Only one patient with JDD was gas-free and was shown to have iodine. JDD was located in the duodenal loop and was divided into right (27), front (15), right Habitat after (9) and the bottom left (5), except for the latter derived from the duodenum horizontal section, the first three from the descending section. CT in the cross-section can be a good show JDD wall and the location of the tube wall of the lower bile duct. Conclusion JDD can cause obvious complications of biliary and pancreatic duct. CT is a very practical and effective imaging method for diagnosing JDD.
