摘　　要：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。AIM To evaluate CT appearance of the juxtapapillary duodenal diverticulum (JDD), in combination of clinical appearance. METHODS Clinical appearance and CT of 55 patients with JDD (n=56) were retrospectively reviewed. RESULTS In 55 cases of JDD, 48 ductal abnormalities were found due to biliary concrements, dilated common bile duct and choiecystitis, and 5 pancreatitis. The most dominant CT sign of JDD was air bubble with (n=1 ) or without (n=32) water and contrast agent between the duodenum and the common bile duct. Only one case showed the contrast without the air in JDD. There were air bubbles In the reticular patterns caused by the undigested food (n=5). According to their position with the bile duct, JDD was divided into four groups: lateral (n=27), anterior (n=15), posterior (n=9) and medialinferior (n=5). JDD of the first three groups originated from the descending duodenum and the 4th from ascending duodenum. CT can show excellently the orientation of both JDD and Vater ampulla. CONCLUSION JDD may be associated with cholangiocholecystopancreatic inflammation and Uthiasis. CT can provide sufficient diagnostic information of JDD.
