An interventional study of NBI during polypectomy and no NBI during polypectomy in Polypectomy, sponsored by Valduce Hospital. Terminated at 1 site in Italy. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-05-21.

Interval colon cancers are an important clinical issue. A recent paper from Pohl et al focused on non-pedunculated polyps of 5-20 mm, evaluating non complete polypectomy revealing that 10% of these polyps were not completely resected. This fact was attributed to size and histology. In this study the investigators want to evaluate the radical resection of non-pedunculated polyps of 5-20 mm by performing biopsies on the margins immediately after polypectomy, to establish if the use of Narrow Band Imaging (NBI) could be useful in the definition of the margins of the lesion before polypectomy.
Interval colon cancers are an important clinical issue. Literature dealing with technics and quality of polypectomy is scarce. A recent paper from Pohl et al focused on non-pedunculated polyps of 5-20 mm, evaluating non complete polypectomy and factors related to it, revealing that 10% of these polyps were not completely resected. This fact was attributed to size and histology (the majority of non completely resected ones, were polyps of 10-20 mm and with serrated characteristics at the histology). In this study the investigators want to evaluate the radical resection of non-pedunculated polyps of 5-20 mm by performing biopsies on the margins immediately after polypectomy, to establish if the use of Narrow Band Imaging (NBI) could be useful in the definition of the margins of the lesion before polypectomy.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
