CONTEXT
Heterotopic pancreas is defined as pancreatic tissue found out of the pancreas proper with no vascular or anatomical connection. It is a rare clinical entity and can be found at any portion of the alimentary system.
CASE REPORT
We describe a case of Meckel's diverticulum with heterotopic pancreas who presented massive lower gastrointestinal bleeding.
CONCLUSION
Lower gastrointestinal bleeding due to Meckel's diverticulum with heterotopic pancreas is extremely difficult to make a definitive diagnosis preoperatively especially when it onsets rapidly.
背景
异位胰腺是指在胰腺固有位置以外发现的胰腺组织，与胰腺本身无血管或解剖学连接。它是一种罕见的临床实体，可出现在消化系统的任何部位。
病例报告
我们描述了一例患有异位胰腺的梅克尔憩室患者，该患者出现大量下消化道出血。
结论
由伴有异位胰腺的梅克尔憩室引起的下消化道出血在术前极难做出明确诊断，尤其是当出血迅速发作时。
