Brief Summary

EndoVigilant software device augments existing colonoscopy procedure video in real-time by highlighting colon polyps and mucosal abnormalities. It is intended to assist gastroenterologists in detection of adenomas and serrated polyps. The device is an adjunctive tool and is not intended to replace physicians' decision making related to detection, diagnosis or treatment. This study with an adaptive design measures the clinical benefit (increase in detection of adenomatous and serrated polyps) and increased risk (increased extraction of non-adenomas) during standard colonoscopy procedures when EndoVigilant software device is used.

Outcome Measures

Primary Outcomes (2)

  • Average Number of Adenomas Per Colonoscopy

    Average Number of Adenomas Per Colonoscopy for all study subjects undergoing colonoscopy procedures, separately calculated for each of the study arms.

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • Average Number of Adenomas Per Extraction

    Percent of extractions that are adenomas per Colonoscopy for all study subjects undergoing colonoscopy procedures, separately calculated for each of the study arms.

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

Secondary Outcomes (11)

  • Average Number of Serrated Polyps per Colonoscopy

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • Average Number of Non-adenomatous, non-serrated polyps per colonoscopy

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • Adenoma Detection Rate in Screening Colonoscopies

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • Serrated Polyp Detection Rate in Screening Colonoscopies

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • Adenoma Detection Rate in All Colonoscopies

    Receipt of pathology results for procedure findings (typically within 2 weeks after the procedure)

  • +6 more secondary outcomes

Study Arms (2)

Colonoscopy Procedure with EndoVigilant Software

EXPERIMENTAL

Colonoscopy Procedure is performed with EndoVigilant Software assisting the gastroenterologist during colonoscopy procedure.

Device: EndoVigilant Software

Colonoscopy Procedure without EndoVigilant Software

NO INTERVENTION

Colonoscopy Procedure is performed without EndoVigilant Software assisting the gastroenterologist during colonoscopy procedure.

Interventions

While using this device, colonoscopy will continue to be performed in the standard manner as is done without the use of this device. The video signal from the colonoscope will be fed into a computer running the EndoVigilant software in addition to the standard video output to the procedure monitor. The gastroenterologist performing the procedure will therefore be able to observe a standard colonoscopy video on the primary monitor and the augmented video on the second monitor. The gastroenterologist may rely on the second monitor (with augmented video generated from EndoVigilant software) for polyp detection, but the standard procedure monitor with the original feed will always be operational and available for maneuvers such as fast insertion, polypectomy etc.

Eligibility Criteria

Age45 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is 45 years old or older.
  • Patient is presenting for colon cancer screening or low-risk surveillance colonoscopy. Low risk surveillance is defined as the patient qualifying for a colonoscopy surveillance interval of 5 years based on US Multi-Society Task Force 2020 Guidelines (i.e., up to 4 tubular adenomas \<1cm, up to 4 sessile serrated polyps \<1cm on most recent colonoscopy).
  • Informed consent document for participating in the study signed by patient or patient's guardian.

You may not qualify if:

  • Patient has known history of inflammatory bowel disease (ulcerative colitis, Crohn's disease).
  • Patient has known or suspected polyposis or hereditary colon cancer syndrome (such as familial adenomatous polyposis, hereditary nonpolyposis colorectal cancer).
  • Patient referred for diagnostic colonoscopy to work up symptoms (such as abdominal pain or bleeding), laboratory abnormalities (such as anemia) or imaging findings (such as masses found on imaging).
  • Patient has history of colon resection (not including appendectomy).
