ABSTRACT：ObjectiveTo evaluate the value of gastric contrast-enhanced ultrasound in diagnosing extraluminal duodenal diverticulum.MethodsAretrospective analysis was conducted on4O cases of extraluminal duodenal diverticula confirmed by upper gastrointestinal barium meal and gastroduodenoscopy，all of whom underwentgastriccontrast-enhanced ultrasound examination.The detection rateand imaging features ofduodenal diverticula were retrospectively analyzed.ResultsGastric contrast-enhanced ultrasound detected 34 outof 4O cases of extraluminal duodenal diverticula，with the detection rate （85.0% ）higher than that（10.0%，4/40）of conventional fasting ultrasound （ P<0.001 ）. Gastric contrast-enhanced ultrasound demonstrated higher detection rate forsinglediverticulathan formultiplediverticula（ 97.1% Us. 44.4% ， P<0.001 ）andwasparticularly effective for duodenal diverticula in the descending segment （91.7% ）. According to imaging features，duodenal diverticula were classified into sac-like，gas-containing mass，and air-line types.ConclusionGastric contrast-enhanced ultrasound facilitates the detectionof extraluminal duodenal diverticula in the descending segment，allows concurrent visualization of biliary-pancreatic systempathologies，and enables comprehensiveassessment of the associationbetween duodenal diverticula and biliary-pancreatic diseases，demonstrating significant clinical value.

十二指肠憩室在肠道憩室中的发生率仅次于结肠憩室，通常位于十二指肠降段乳头附近，根据憩室的膨出方向分为腔内型和腔外型，其中腔外型更为常见，约 90% 无明显临床症状，仅在检查中偶然发现[2]。（剩余7100字）
