Abstract
Background and study aims Diagnosis of Meckel’s diverticulum (MD) before
surgery may be challenging; double-balloon endoscopy (DBE) facilitates
identification of MD in the setting of a gastrointestinal bleeding; however, MD
can be found incidentally without this condition. The purpose of this research
was to determine specific characteristic of hemorrhagic MD and incidental MD at
DBE.
Patients and methods Ectopic gastric mucosa enclosed in the MD and/or
ulceration were defined as “major findings”; ring-like scar surrounding the MD
was defined as “minor finding”. We retrospectively reviewed the medical records
of patients affected by MD and analyzed the findings that significantly affected
the characterization of MD.
Results MD was diagnosed in 33 patients. The axis of the diverticulum was
longer in hemorrhagic MD compared to incidental MD (P = 0.031). The
amount of transfusion was significantly higher (P = 0.018) in the
hemorrhagic MD group. Hemorrhagic MD was significantly more correlated with
major findings (P = 0.01) and minor findings (P < 0.01). The
specificity of major finding was 100 % while the sensitivity of major and/or
minor findings was 96 %.
Conclusions The combination of major and minor findings appears to improve
the diagnostic ability of hemorrhagic MD avoiding unnecessary
diverticulectomy.
