摘要

據文獻記載，反轉梅克爾氏憩室發生率甚低，它可能造成臨床併發症有：出血，腸阻塞，腸穿孔，腸絞勒，陽扭轉及腸套疊等。出血因素為異位性胃黏膜潰瘍所造成。電腦斷層攝影可發現卵黃管遺跡似脂肪密度腫塊充填於腸腔內。而於血管攝影可發現永存的卵黃動脈，且可同時偵測是否有活動性出血。在此我們報告一病例，經手術證實因反轉梅克爾氏憩室引發腸胃道出血，並呈現其影像學上之表現。

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, occurring in about 2-3% of the population. It is the remnant of omphalomesenteric (vitelline) duct, which is usually located within 100 cm of the antimesenteric border of the terminal ileum. Meckel's diverticulum rarely causes symptoms, but sometimes it may invert or invaginate into the intestinal lumen, causing intussusception, obstruction, or intestinal bleeding. We present a rare case of Meckel's diverticulum inverting into the ileal lumen causing vague abdominal pain and lower gastrointestinal bleeding.
