The present study was performed to test the reliability of in situ measurements of colorectal polyps when comparing videoendoscopes with fiberoptic endoscopes. In 25 small rectosigmoid polyps 3-12 mm) removed endoscopically, in situ diameters were measured before polypectomy using both video- and fiberoptic endoscopes. Polaroid and videoprint pictures were taken for computerised analysis of the area of the polyps on the pictures. The results showed a good correlation between the polyp diameter measured with the videoendoscope and fiberoptic endoscope (r = 0.97), with no significant difference by parametric testing. The diameter and weight of the removed polyp also correlated well with the diameter measured in situ using videoendoscopes (r = 0.92 and 0.77, respectively) or fiberoptic endoscopes (r = 0.90 and 0.81, respectively). Furthermore, the weight of the removed polyp correlated reasonably well to the computerised area measurement, the correlation coefficient being r = 0.90 for fiberoptic endoscopes and r = 0.75 for videoendoscopes. We conclude that in situ polyp diameter measurements using videoendscopes and fiberoptic endoscopes are similarly reliable and sensitive, and both instruments can be used interchangeably in follow-up studies of polyp growth.
