Summary
Barium enema revealed redundant colon in 68% of patients with incomplete colonoscopy, compared to 33% in those with complete procedures. This imaging technique aids in identifying anatomical variations after failed colonoscopies.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
Background:
- Incomplete colonoscopy presents diagnostic challenges.
- Barium enema is a valuable tool for colonic evaluation.
Purpose of the Study:
- To assess the utility of barium enema in patients with incomplete colonoscopy.
- To identify common findings, such as redundant anatomy, in this patient group.
Main Methods:
- Retrospective review of 108 barium enemas performed within 6 months of an incomplete colonoscopy (1991-1997).
- Comparison with a control group (27 patients) who had complete colonoscopies.
- Re-evaluation of barium enemas for redundant colon and other lesions.
Main Results:
- A redundant colon was the most frequent finding, present in 68% (55/81) of patients with incomplete colonoscopies.
- In contrast, only 33% (9/27) of patients with complete colonoscopies showed redundant colons.
- Seventy-seven women and 30 men were included in the study cohort.
Conclusions:
- Barium enema is effective in detecting redundant colons in patients with incomplete colonoscopies.
- Findings suggest a higher prevalence of redundant colons in patients experiencing incomplete colonoscopy.
- Barium enema can provide valuable anatomical information when colonoscopy is unsuccessful.
