Abstract:
Objective To evaluate the value of gastric contrast-enhanced ultrasound in diagnosing extraluminal duodenal diverticulum. Methods A retrospective analysis was conducted on 40 cases of extraluminal duodenal diverticula confirmed by upper gastrointestinal barium meal and gastroduodenoscopy,all of whom underwent gastric contrast-enhanced ultrasound examination.The detection rate and imaging features of duodenal diverticula were retrospectively analyzed. Results Gastric contrast-enhanced ultrasound detected 34 out of 40 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 for single diverticula than for multiple diverticula (97.1% vs.44.4%,P<0.001) and was particularly 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. Conclusion Gastric contrast-enhanced ultrasound facilitates the detection of extraluminal duodenal diverticula in the descending segment,allows concurrent visualization of biliary-pancreatic system pathologies,and enables comprehensive assessment of the association between duodenal diverticula and biliary-pancreatic diseases,demonstrating significant clinical value.
