Abstract:
Objective To evaluate endoscopic ultrasonography (EUS) for diagnosis and treatment of ectopic pancreas in upper gastrointestinal tract.Methods Data of 52 patients with ectopic pancreas diagnosed by EUS and confirmed by pathological examination were reviewed.The feature of EUS image and diagnostic accuracy were retrospectively analyzed.Results Out of 52 patients, 41 (78.85% ) were pathologically diagnosed as having ectopic pancreas, 6 were stromal tumors, 4 were leiomyoma and 1 was nerve sheath tumor.All ectopic pancreases presented as protruding lesions, in which 37 were located at gastric antrum, 2 in duodenum, 1 in gastric body and 1 in gastric fundus.Under EUS, 1 case appeared as hyperechoic, 10 as isoechoic, 18 as hypoechoic and 12 as mixed echoic.The lesion involved mucosa in 2 cases, muscularis mu-cosae in 8, submucosa in 30 and muscularis propria in 1, in which 15 cases from submucosa underwent endoscopic resection.Bleeding occurred in 2 cases and no other complications occurred.There was one relapse during the 6 months of followed-up.Conclusion EUS is valuable and safe for the diagnosis of ectopic pancreas in upper gastrointestinal tract.Depth of lesions revealed by EUS can help further treatment.
