【摘要】 本文报告胃肠道异位胰腺24例,男19例,女5例。其中胃7例(29％),十二指肠5例(21％),空肠12例(50％)。异位胰腺引起病变与症状者10例。异位胰腺的病理形态学与正常胰腺组织相似,包括腺泡、导管与胰岛。本组有22例次见到腺泡与导管,有14例次见到胰岛细胞。有2例仅见大中小导管,周围平滑肌纤维增生,其中1例经过连续切片见到少量胰腺小叶。有12例次见到不同程度的肌上皮瘤样组织。本病的术前诊断困难,要借助于X线的钡剂检查,发现导管充满钡剂的阴影。冰冻切片对诊断胃肠道异位胰腺有一定价值。更多还原

【Abstract】 This series consists of 19 male and 5 female subjects. The locations of ectopia are gastric wall in 7 cases (29％), duodenal wall in 5 (21％), and jejunal wall in 12(50％). Clinical symptoms are present in 10 cases. The histologic structure of ectopic pancreas is similar to that of pancreas in normal location. In this series acini and ducts are seen 22 times in 24 cases, islet cells 14 times, ducts of varying sizes with proliferation of surrounding smooth muscle fibers 2 times, and varying degrees of growth of the myoepithelial cells 12 times. In one case serial sections show a small number of pancreatic lobules. Preoperative diagnosis is diffieult; in none of the cases in this series a correct preoperative diagnosis is rendered. A demonstration of barium-filled ducts may be helpful in arriving at a correct diagnosis.更多还原
