目的评价多层螺旋CT(multislice spiral CT,MSCT)用于诊断十二指肠憩室的临床意义。方法对106例经上消化道钡餐造影或/和胃十二指肠镜诊断证实的十二指肠憩室患者的MSCT资料进行回顾性分析。结果106例患者共有118个十二指肠憩室。其中,有37个(31.36%)憩室直径小于1.0 cm,有45个(38.14%)憩室直径介于1.0~2.0 cm之间,其余36个(30.51%)憩室直径大于2.0 cm。有17个(14.41%)憩室在十二指肠的球后段,有19个(16.10%)憩室在十二指肠的水平段,其余82个(69.49%)憩室在十二指肠的乳头旁。有52个(44.07%)憩室的MSCT表现为液性囊状,有5个(4.24%)憩室表现为气性囊状,其余61个(51.69%)憩室表现为液性与气性混合囊状。106例患者中有71.70%的患者并发有胆总管扩张,有73.58%的患者并发有胆囊病变。有胆胰类并发症与无相应并发症的十二指肠乳头旁憩室患者憩室的最大直径相差不大,两者比较差异无统计学意义(P>0.05)。结论 MSCT可很好地诊断十二指肠憩室,能及时发现相关的胆胰类并发症,值得临床推广应用。
Objective To evaluate the clinical value of multislice spiral CT (MSCT) in the diagnosis of duodenal diverticula. Methods Retrospective analysis of MSCT data of 106 patients with duodenal diverticulum diagnosed by upper gastrointestinal barium meal or / and gastroduodenoscopy. Results A total of 118 patients with duodenal diverticulum. Of these, 37 (31.36%) diverticula were less than 1.0 cm in diameter, 45 (38.14%) diverticula were between 1.0 and 2.0 cm in diameter, and the remaining 36 (30.51%) diverticula were larger than 2.0 cm in diameter. There were 17 (14.41%) diverticulum in the posterior segment of the duodenum, 19 (16.10%) diverticulum in the level of the duodenum and the remaining 82 (69.49%) in the duodenal papilla beside. There were 52 (44.07%) diverticulitis with cystic cystic MSCT, 5 (4.24%) diverticulitis with cystic cyst and 61 (51.69%) diverticula with limpid and gas cystic . Among the 106 patients, 71.70% of patients had concurrent dilatation of the common bile duct, and 73.58% of patients had gallbladder lesions. There was no significant difference in the maximum diameter of diverticula with gallbladder and pancreatic complications in patients with duodenal papillary diverticula without complication, the difference was not statistically significant (P> 0.05). Conclusions MSCT can diagnose duodenal diverticulum well and can detect the relevant biliary and pancreatic complications in time, which is worthy of clinical application.
