The authors used a database of Medicare beneficiaries aged 65 years and older to identify individuals who were cancer-free and who had undergone at least one colonoscopy or sigmoidoscopy between 1991 and 1998, and they then calculated the incidence and risk of perforation within seven days of the procedure.During 39,286 colonoscopies, there were 77 perforations, or 1.96 perforations per 1,000 procedures, compared with 31 perforations during 35,298 sigmoidoscopies, or 0.88 perforations per 1,000 procedures.

Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.

Results show that amplitude of displacement excited by vertical incidence wave is larger than that excited by inclined incidence wave and not influenced greatly by the incidence angle. In vertical incidence, amplitudes of displacement of two points at the same altitude along each cavern are basically identical and maximum relative displacement occurs between top and bottom point of the cavern. While in the case of inclined incidence, displacement amplitude on sides meeting the wave is larger than that on leed sides, and maximum relative displacement occurs on left skewback and bottom of the cavern.
