Colonoscopy in the evaluation of strictures

Area of Science:

• Gastroenterology
• Endoscopy
• Diagnostic Imaging

Background:

• Colonic strictures present diagnostic challenges.
• Barium enema may yield inconclusive results for stricture etiology.
• Colonoscopy offers a potential solution for unclear cases.

Purpose of the Study:

• To evaluate the diagnostic utility of colonoscopy for colonic strictures.
• To determine the success rate of colonoscopy in resolving stricture etiology when barium enema is inconclusive.

Main Methods:

• Review of 181 consecutive colonoscopic procedures.
• Procedures performed for inconclusive barium enema findings in colonic strictures.
• Analysis of intubation success and problem resolution rates.

Main Results:

• Colonoscopy successfully intubated the colon above the stricture in 54% of cases.
• In cases where stricture traversal was impossible (46%), biopsy and cytology resolved the issue in 13% of those cases.
• Overall, colonoscopy was helpful and diagnostic in 67% of the reviewed procedures.

Conclusions:

• Colonoscopy is a valuable tool for diagnosing the etiology of colonic strictures.
• The procedure offers a high success rate in resolving diagnostic uncertainty when initial imaging is inconclusive.
• Combined techniques of biopsy and cytology enhance diagnostic yield in challenging stricture cases.
