During the study period 3849 (15.1%) of all family physicians performed rigid sigmoidoscopy; the proportion varied from 3.4% (in Quebec) to 40.0% (in the Northwest Territories). A total of 43 914 rigid sigmoidoscopies were performed by family physicians, representing 23% of all such procedures. Flexible sigmoidoscopy was performed by 381 (1.5%) of all family physicians; the proportion varied from 0.4% (in Quebec) to 6.8% (in Prince Edward Island). A total of 5361 flexible sigmoidoscopies were performed, representing 6.0% of all such procedures.Conclusion
