In the hands of a reputable doctor either one can find polyps or other problems. The difference is that a colonoscope can be inserted further up into the colon than the sigmoidoscope. Cancer in the upper part of the colon cannot be detected with a sigmoidoscopy. My gastroenterologist does both procedures and there was literature about both in his office.
As a young doctor in the 1970s I used a rigid two-foot long sigmoidoscope to check my patients for hemorrhoids, colon polyps, and cancer. The procedure was painful, relatively safe, cost about $100, and could be performed in about 10 minutes without any sedation in my office. Colonoscopies became popular as a screening tool in the late 1970s. Because this instrument (the colonoscope) must travel through 6 feet of torturous and turning bowel with four right angle turns (rather than only 2 feet with two bends with a sigmoidoscope) much more is involved. The colonoscopy requires a thorough bowel preparation (lasting as long as three days), sedation, and at least 30 minutes to perform. The risks from the sedation and passage of the tube are considerable. In contrast, nowadays a much more comfortable sigmoidoscope exam (using a flexible instrument) can be performed, which requires at most a day of preparation, costs about $200, and can be completed in 10 minutes. No sedation is required and harm is rarely caused to the patient. Adequately trained nurse practitioners can perform flexible sigmoidoscopy as competently as gastroenterologists can.

colonoscopy can be useful...he may vary his approach depending on YOUR situation..
