Colonoscopy as an adjunctive technique in evaluating acquired colonic narrowing

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Barium enema can be inconclusive in diagnosing colonic narrowing.
• Surgical intervention for colonic narrowing requires accurate diagnosis of its nature.

Observation:

• Fiberoptic colonoscopy was reviewed in 500 procedures, with 47 cases of colonic narrowing.
• Barium enema was inconclusive in 34 of these cases, while colonoscopy was inconclusive in only seven.

Findings:

• Colonoscopy influenced surgical management decisions in 34 patients.
• Endoscopic findings were confirmed by biopsy, laparoscopy, or celiotomy.
• 29 patients avoided exploratory surgery based on combined radiographic and endoscopic studies, with no delay in malignancy diagnosis.

Implications:

• Fiberoptic colonoscopy is a valuable tool for determining the nature of colonic narrowing, potentially avoiding unnecessary surgery.
• Accurate endoscopic diagnosis can limit the extent of resection, even for benign processes.
• Colonoscopy enhances diagnostic accuracy and influences surgical planning for colonic narrowing.
