Colonoscopic polypectomy in a regional teaching hospital

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Endoscopy

Background:

• Colonic polyps are common and can be precursors to cancer.
• Understanding polyp characteristics and recurrence is crucial for patient management.
• Regional centers manage a similar spectrum of colonic polyp cases as specialist units.

Purpose of the Study:

• To analyze the characteristics and recurrence rates of colonic polyps in a regional teaching hospital.
• To compare findings with large, metropolitan referral center studies.
• To establish optimal follow-up surveillance protocols for patients with colonic polyps.

Main Methods:

• Retrospective analysis of 200 patients undergoing colonoscopy over 6 years.
• Inclusion of polyp size, distribution, histology, and recurrence data.
• Statistical comparison with existing literature.

Main Results:

• 535 polyps were identified in 200 patients.
• Polyp presentation, complications, size, distribution, and histology mirrored metropolitan data.
• A smaller proportion of polyps exceeded 1 cm in diameter.
• 25-53% of patients had recurrent or residual polyps on follow-up colonoscopy.
• Patients with multiple initial polyps had a significantly higher likelihood of recurrence (P < 0.01).

Conclusions:

• Colonic polyp management in regional centers reflects findings from major referral hospitals.
• High recurrence rates, particularly in patients with multiple initial polyps, warrant close monitoring.
• Recommended surveillance: annual colonoscopy until polyp-free for 2 years, then 5-year intervals.
