Importance of Gastric Mucosa in Meckel's Diverticulum

Abstract

ing from the rectum. The mother states that her child (probably from 1 to 6 years old, rarely over 12) has suddenly passed a large amount of blood. An analysis of the amount of blood passed and its color is of prime importance. If the stool containing blood was passed in the toilet bowl the mother will have overemphasized the amount of blood passed; even a teaspoonful of blood in the bowl will make the water red enough to frighten the mother. The color of the blood is equally important. Usually, the first bowel movement in an otherwise normal child will be formed and will contain some brick-red blood. The second movement likewise will be brick-red.

Gastrointestinal Bleeding Caused by Meckel's Diverticulum Diagnosed by Double Balloon Enteroscopy: Three Cases and a Brief Literature Review

“…Similarly, one of our three cases had gastric mucosa in biopsy specimens. with ectopic gastric mucosa among those with diverticular bleeding has been reported to range from 77.8% to 98.0% [7]. Although it has varied clinical presentations, early diagnosis is still one of the most challenging issues in clinical practice.…”

Possible Role of Meckel’s Scan Fused with SPECT CT Imaging: Unraveling the Cause of Abdominal Pain and Obscure-Overt Gastrointestinal Bleeding

“…Ectopic mucosa is present in ∼50%, of which 60% contain gastric mucosa [10], which increases to 90% of bleeding Meckel's diverticula [11]. Diagnostic accuracy of the Meckel's scan is >90% in the pediatric population [12] but is less accurate in adults (sensitivity 62.5%, positive predictive value 60% [13]), which is in part because complications in adults are less commonly associated with ectopic gastric mucosa [14].…”

Das Meckel-Divertikel: Sicherheit der Resektion symptomatischer und asymptomatischer Befunde und Literaturübersicht

“…Komplizierte MD können in allen Altersgruppen auftreten und sollten bei Patienten aller Altersgruppen mit unklaren abdominellen Beschwerden in die Differenzialdiagnose einbezogen werden [6,8,20,39,46]. Sicher erscheint, dass sich Heterotopien wie ektope Magenschleimhaut und ektopes Pankreasgewebe bei Patienten mit symptomatischen MD häufiger finden als bei Patienten mit asymptomatischen MD [5,18,51,52]. So konnte in einer retrospektiven Untersuchung von 1082 resezierten MD bei 43 % der symptomatischen MD ektopes Gewebe gefunden werden, jedoch nur bei 14 % der asymptomatischen MD [9].…”
