Flat colonic neoplasms detected by barium enema may be missed during endoscopy. Repeat barium enema is recommended if endoscopy fails to find suspected colonic tumors.

Area of Science:

  • Gastroenterology
  • Colorectal Cancer Screening
  • Diagnostic Imaging

Background:

  • Endoscopy is the gold standard for evaluating colonic neoplasms.
  • Barium enemas can detect colonic lesions, but confirmation often relies on endoscopy reaching the target area.

Purpose of the Study:

  • To investigate cases where colonic neoplasms were detected by barium enema but missed during initial endoscopy.
  • To assess the implications of missed diagnoses on patient outcomes.

Main Methods:

  • Retrospective review of 18 cases with confirmed colonic neoplasms (2-8 cm) initially detected by barium enema.
  • Analysis of endoscopic and histopathological findings for missed lesions.

Main Results:

  • All 18 lesions were relatively flat and had minimal intraluminal protrusion.

  • Malignant foci were found in 6 of 11 resected tumors.
  • Two unresected lesions progressed to advanced carcinomas.

    • Conclusions:

    • Flat colonic neoplasms can be overlooked during standard endoscopy.
    • A repeat barium enema is indicated when endoscopy fails to detect a colonic tumor suspected on prior barium enema examination.
