A Follow-up Colonoscopy Examination in Patients Who Had Previously Undergone Screening Colonoscopy
Colorectal cancer (CRC) is the second commonest cancer in Hong Kong, and tends to be
increasing. Screening for colorectal cancer can reduce the cancer incidence and mortality
by detecting early lesions. However, the best interval for a follow up colonoscopy,
particularly for those with normal baseline colonoscopy, remains largely unknown.
This study aim to determine the prevalence of colonic neoplasm in average-risk patients who
had previously undergone screening colonoscopy and the optimal time interval for
re-screening.
Inclusion Criteria:
- Subjects who are previously participated in one of our two screening colonoscopy
studies [Sung, Gastroenterol 2003; Leung, AJG 2004]
- Asymptomatic on first screening colonoscopy
- Age>50and <75
- No family history of CRC
- No other colonoscopy except the baseline screening colonoscopy
Exclusion Criteria:
- Subjects who refused consent
- Subjects who are not warrant follow up colonoscopy
Type of Study:
Observational
Study Design:
Observational Model: Case Control, Time Perspective: Prospective
Outcome Measure:
The prevalence of advanced colonic adenoma in the re-screening population
Outcome Time Frame:
5 year from index colonoscopy
Safety Issue:
No
