Summary
Collagenous colitis patients with mucosal tears during colonoscopy face an increased risk of colonic perforation. Awareness of these endoscopic findings is crucial for preventing serious complications.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- Collagenous colitis typically presents with a macroscopically normal colonic mucosa.
- Mucosal tears, or longitudinal mucosal lacerations, are uncommon but significant endoscopic findings in collagenous colitis.
Observation:
- This report details three cases of women with collagenous colitis and mucosal tears identified during colonoscopy.
- A literature review identified a total of 12 reported cases, including these three.
- Mucosal lacerations most frequently involved the ascending or transverse colon.
Findings:
- Three out of 12 patients with collagenous colitis and mucosal tears experienced immediate colonic perforation post-colonoscopy.
- The presence of mucosal tears appears to correlate with a heightened risk of iatrogenic perforation.
Implications:
- Colonoscopists must recognize the endoscopic characteristics of mucosal tears in collagenous colitis.
- Increased vigilance is necessary during colonoscopy in patients with collagenous colitis, particularly when mucosal tears are observed, due to the elevated risk of perforation.
