Capsule endoscopy (CE) effectively diagnoses Meckel's diverticulum, identifying characteristic lesions like double lumens and protruding or caved signs. This imaging technique aids in diagnosing this gastrointestinal condition when other methods fail.

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Surgical Pathology

Background:

  • Meckel's diverticulum is a congenital anomaly of the small intestine.
  • Diagnosis can be challenging, often requiring advanced imaging techniques.
  • Capsule endoscopy (CE) offers a minimally invasive approach to visualize the small bowel.

Purpose of the Study:

  • To describe a case series of Meckel's diverticulum diagnosed via capsule endoscopy.
  • To review literature and identify common CE characteristics of Meckel's diverticulum.
  • To evaluate CE as a diagnostic tool for Meckel's diverticulum.

Main Methods:

  • Retrospective review of four patients diagnosed with Meckel's diverticulum using CE.
  • Patients presented with hematochezia or abdominal pain, with negative upper endoscopy and colonoscopy.

  • Analysis of CE findings, including lesion appearance and capsule behavior.

    • Main Results:

    • Capsule endoscopy detected Meckel's diverticulum in all four patients.
    • Observed CE features included double lumen sign, diaphragm sign, protruding lesions, caved lesions, and capsule retention.
    • Visible blood was noted in one case, and capsule retention occurred in a blind end in another.

    Conclusions:

    • Capsule endoscopy is a valuable tool for diagnosing Meckel's diverticulum.
    • Specific CE findings like protruding/caved lesions, solitary polyps, and stenosing lesions aid diagnosis.
    • While the double lumen sign is characteristic, other findings are also diagnostic.
