Feasibility of 105-cm flexible sigmoidoscopy in family practice.

The 105-cm flexible sigmoidoscope was studied for the feasibility of its use in a family practice setting in screening for colorectal cancers and polyps. A total of 49 examinations were performed. The average length of colon examined was 71 cm. Insertion to 105 cm was accomplished in 14 patients (29 percent) and exceeded 65 cm in 28 patients (57 percent). No complications of the procedure were encountered. The study indicated that some patients, with no special preparation or medications and no additional discomfort, might benefit by the more thorough screening afforded by 105-cm flexible sigmoidoscope. What is not yet known is the efficacy of large-scale screening for cancers and polyps utilizing the 105-cm flexible sigmoidoscope in the family practice setting.
