Abstract:
Objective The aim of this study was to explore the value of ultrasound in the diagnosis of Lemmel syndrome. Methods Ultrasound images of 36 patients with Lemmel syndrome confirmed by ERCP or surgery were retrospectively analyzed, and the image′s feature of ultrasound was explored. Results The ultrasound feature of Lemmel syndrome was showed as cystic protuberance from lesser curvature of duodenum, and three types of ultrasound characteristics were found: hyperechogenicity of gas, solid-cystic echogenicity full filled with fluid and inhomogeneous echogenicity full filled with food residue. The presence of hyperechogenicity (24 cases), solid-cystic echogenicity (8 cases), inhomogeneous echogenicity (4 cases) were found in 36 patients with periampullary diverticulum, and the biggest diameter of periampullary diverticulum was 6 to 32 mm. All of the patients (36 cases) were with mechanical obstruction in the common bile duct, and 12 patients were found mild dilatation of the pancreatic duct. Conclusion Higher clinical application value of ultrasound has been found when ultrasound is used in the diagnosis of Lemmel syndrome.
