담도 췌장 ; 중심부 함몰이 없는 이소성 췌장의 내시경적 초음파단층촬영술 소견

Background/Aims: A gastric aberrant pancreas can be easily diagnosed through con- ventional endoscopy and radiologic modalities due to its characteristic features such as central dimpling. However, in cases involving an aberrant pancreas without the central dimpling, the differential diagnosis has been some troublesome. As for differential diag- nosis of gastric submucosal tumors, endoscopic ultrasonography (EUS) allows us to visu- alize the structures underlying the gastrointestinal wall in a non-invasive manner, and has a great advantage over conventional modalities such as conventional endoscopy or the UGI series. Methods: We studied the EUS findings of a gastric aberrant pancreas without the central dimpling. We compared EUS features in 10 cases involving a gastric aberrant pancreas without the central dimpling to those in 16 cases with the central dimpling.
