Brief Summary:
Benign adenomas of the colon have the potential to degenerate and become malignant. Therefore adenomatous polyps should be detected and resected during colonoscopy. Factors like advanced age and male gender are associated with the detection of adenomas. The same epidemiological pattern can be found with regard to colon diverticula. Furthermore, western world countries report higher incidences of both colorectal carcinoma as well as diverticular disease. It is not known whether a correlation exists between both entities. Some recent data have postulated higher adenoma detection rates in patients with concomitant diverticular disease (Rondagh EJ et al. Eur J Gastroenterol Hepatol. 2011; 23:1050-5. Kieff BJ et al. Am J Gastroenterol 2004; 99: 2007-11). If a positive correlation could be found this would possibly affect recommendations regarding colonoscopy surveillance intervals for patients with and without diverticular disease. The investigators therefore plan to conduct the following trial.

Study Type : Observational
Actual Enrollment : 1000 participants
Observational Model: Cohort
Time Perspective: Prospective
Study Start Date : February 2014
Actual Primary Completion Date : September 2016
Estimated Study Completion Date : March 2017

Group/Cohort
Routine colonoscopy
Patients receiving routine colonoscopy (for a multitude of indications) at the study centers are eligible for participation



Primary Outcome Measures :
  1. Adenoma detection rate [ Time Frame: up to 2 weeks (participants will be followed for the duration of hospital stay or outpatient treatment, an expected average of 2 weeks) ]
    After obtaining the histopathological diagnosis of resected polyps (approximately 3 days - 2 weeks after colonoscopy ) accuracy of optical diagnosis can be determined


Secondary Outcome Measures :
  1. Polyp detection rate [ Time Frame: up to one day ]
    a maximum of one day is expected for colonoscopy

  2. Frequency of colon diverticulosis [ Time Frame: up to one day ]
    a maximum of one day is expected for colonoscopy


Biospecimen Retention:   Samples Without DNA
Colon polyps and mucosa
