AbstractBackground: Currently there are conflicts about the prevalence of proximal colorectal polyp/s among
patients with distal colorectal polyp/s discovered by sigmoidoscopy.
Design: A retrospective study.
Setting: Gastroenterology and Hepatology Teaching Hospital –Baghdad –Iraq.
Patients and methods: During the study period (1st of August-2003 to 31 of December -2004) all
patients who underwent total colonoscopy procedure were involved in this study. Out of patients with
different polyps, 96 patients were included when they did not have the Exclusion criteria.
Results: This study included ninety-six patients, (Male= 67(69.8%), Female= 29(30.2%)) mean age of
patients 51.5 year. Forty two (62.7%) of male patients had distal colorectal polyp (CRP), 30.9 %( 13 of
42) had proximal one (combined), while in female patients 21 patients had distal CRP, 14.3% (3 of 21)
had combined CRP. For adult patients with distal CRP, 26.8% (11 of 41) had combined CRP, all pediatric
patients had distal CRP, and 22.7% of them had combined CRP. Seven (14.6%) patients with distal single
CRP had combined one, while in patients with multiple CRP, 60 %( 9 of 15) of patients with distal
multiple CRP had combined one. With regard to the size of polyps, 26 %( 13 of 50) of patients with distal
small CRP (<1cm) had combined one, while in those patients who had distal CRP ≥ 1 cm, 23.1 %( 3 of
13) had combined one, 32.3 %( 10 of 31) of patients with distal neoplastic CRP had combined one, while
in patients with distal non- Neoplastic CRP, 18.8%(6 of 32) had combined CRP.
Conclusions and recommendations:
1. All patients with distal colorectal polyp/s discovered during sigmoidoscopy should undergo total
2. Colonoscopy should be used as a screening procedure instead of sigmoidoscopy.
3. Sigmoidoscopy can be used as a screening procedure in pediatric patients
