ENDOSCOPIC CHARACTERIZATION OF A DIMINUTIVE SPORADIC BRAF-MUTANT TRADITIONAL SERRATED ADENOMA ARISING FROM A SESSILE SERRATED LESION

Video Transcription

Video Summary

The video discusses the endoscopic characterization of a rare type of polyp called a traditional serrated adenoma (TSA) that arises from a sessile serrated lesion (SSL). The video describes a case study of a 29-year-old female who had a 5mm TSA in her colon. The endoscopic diagnosis was made using high-definition white light and narrowband imaging. The polyp was resected using a specific technique called unblock endoscopic mucosal resection. The video emphasizes the importance of optical diagnosis during routine colonoscopy, even for small polyps. The clinical implications of this case include the early detection and removal of BRAF mutant TSAs arising from SSLs. No credits are mentioned.
