Finally, he points out that it is inappropriate to carry out an incomplete examination on screened patients and thereby perhaps give false reassurance. We would agree with this general sentiment but must point out that he has partly based his viewpoint on a study that found no more pathology in these people than in the general population3. Colonoscopy is an investigation with a morbidity and mortality rate. We believe that the evidence to advocate a 'blanket' policy of colonoscopy for all levels of family risk has not been shown by the currently available data.
