Radiologic Diagnosis of Gastroduodenal Intussusception: A Case Report

胃十二指腸套疊的放射線診斷:病例報告

摘要


胃十二指腸套疊是一罕見的病症,通常發生在一個活動性的胃腫瘤,導致胃壁垂脫到十二指腸。本病例為一胃平滑肌瘤引發胃與十二指腸之套疊。無特異之臨床表徵,常可用上腸胃道鋇劑檢查和腹部電腦斷層檢查于手術前診斷。放射線攝影之典型表徵包括:遠端會聚的胃皺壁、內摺和向外鼓出的胃壁,胃壁套入部和導引腫瘤在擴張的胃幽門和十二指腸造成填充缺損。但導引腫瘤的組織類別還是需要切除標本的病理診斷才能確定。

並列摘要


Gastroduodenal intussusception is a rarely documented condition which occurs usually when a mobile leading gastric tumor prolapses into the duodenum with subsequent invagination of a portion of the stomach wall. An example of this condition, associated with a gastric leiomyoma, is presented herein. The patients clinical manifestations were non-specific. Correct preoperative diagnosis was made by upper gastrointestinal series and computed tomography (CT) study. The typical radiographic signs include distal converging gastric folds, infoldings and outpouchings of the gastric wall, gastric intussusceptum presenting as a filling defect and a leading tumor in the dilated duodenum. The histological nature of the leading tumor can not be determined until examination of the resected specimen.
