Nowadays, post-polypectomy surveillance intervals are determined by combining endoscopic and pathologic data. Real-time imaging technologies, have shown promising results in discriminating adenomatous from non-adenomatous polyps.

The "resect and discard strategy" for small polyps (based on real-time assessment of the histology and on the endoscopic resection without pathological examination) has been shown to be cost-effective in simulation models. No data exist about the impact of this strategy in clinical practice.

The aim of present study was to assess whether the systematic use, in the everyday clinical practice, of the "resect and discard strategy" allows to correctly manage patients with small colonic polyps.

Further study details as provided by Valduce Hospital:

Primary Outcome Measures:
  • The primary outcome of the study was to assess the agreement between "endoscopy-" and "histology-determined" surveillance strategies after small adenoma resection.

Secondary Outcome Measures:
  • sensitivity of the endoscopic assessment (WL coupled with NBI) of small (<10 mm) adenomas
  • operative characteristics for the diagnosis of diminutive (< 5 mm) adenomas
  • the feasibility of non histologic evaluation, represented by the proportion of polyps in which a in-vivo diagnosis of adenoma can be made with high confidence
  • specificity of the endoscopic assessment
  • accuracy of the endoscopic assessment

Enrollment: 286
Study Start Date: February 2011
Groups/Cohorts Assigned Interventions
small polyps patients
Patients with one small polyps at colonoscopy
Other: endoscopic assessment of colonic polyps


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Consecutive adult outpatients undergoing colonoscopy for routine clinical indications

Inclusion Criteria:

  • consecutive adult outpatients undergoing colonoscopy for routine clinical indications

Exclusion Criteria:

  • surveillance interval was not necessarily directed by endoscopic findings (history of colorectal cancer, inflammatory bowel disease, hereditary polyposis syndromes, hereditary non-polyposis colorectal cancer)
  • colonoscopy was performed without NBI technology
  • at least one lesion > 10 mm or < 10 mm but with morphologic features suspect for malignancy (depressed or ulcerated lesions) was detected
  • bowel preparation was inadequate
  • caecal intubation was not accomplished
  • polyps could not be resected for concomitant anticoagulation treatment, 7) polyps were resected but not retrieved for pathology.
