Tip 11: Why Do We Biopsy Cancers as a Last Step in Colonoscopy?

Video Transcription

Video Summary

The video transcript is from a colonoscopy on the ASGE SuTab tip of the week. The patient had a referral for resection of a 12 to 13 millimeter sessile lesion in the distal transverse colon. The video shows the examination of the colon, including finding a lesion with the morphology of cancer and the removal of multiple lesions using electrocautery and snare cautery. The video emphasizes the importance of checking the entire colon for synchronous disease and the high prevalence of additional adenomas in patients referred for sessile lesions. The video also discusses the delay of biopsy in cases of cancer and the risk of intraluminal tumor seeding. No credits are granted in the video transcript.
