Summary

Regular screening colonoscopies can detect and remove early-stage colorectal cancer polyps safely and affordably. This study indicates that colonoscopy is a cost-effective method for reducing cancer incidence and mortality.

Area of Science:

  • Gastroenterology
  • Oncology
  • Preventive Medicine

Background:

  • Colorectal cancer (CRC) incidence and mortality can be reduced through early detection and removal of precancerous lesions.
  • Screening programs must be cost-effective, safe, and time-efficient to be widely adopted.

Purpose of the Study:

  • To evaluate the safety, cost-effectiveness, and time efficiency of screening colonoscopy in an office setting.
  • To assess the yield of adenomatous and hyperplastic polyps, including adenocarcinomas, during screening colonoscopies.

Main Methods:

  • A total of 639 patients underwent screening colonoscopy in an office facility.
  • Physician time for normal examinations was minimized, including sedation, the procedure, and reporting.
  • The total charge for a normal screening colonoscopy was established at $150.

Main Results:

  • Polyps (adenomatous and/or hyperplastic) were detected in 34.1% of patients, with 160 adenomatous and 134 hyperplastic polyps removed.
  • Six adenocarcinomas were identified in five patients.
  • Complications were minimal, including one case of delayed bleeding and one of post-polypectomy syndrome, both requiring no intervention. Average physician time was 18 minutes for normal exams.

Conclusions:

  • Screening colonoscopy is a safe and efficient procedure that can be performed in an office setting.
  • Limiting physician time contributes to a low cost, making it competitive with other cancer screening methods.
  • Further long-term studies are warranted to confirm the impact of screening colonoscopy on CRC mortality reduction.
