Video Transcription

Video Summary

The video demonstrates two different techniques of sphincter-preserving endoscopic resection of anorectal gist. The first case involved a 57-year-old male who refused abdominal perineal resection and was started on neoadjuvant imatinib. Submucosal tunneling endoscopic resection was performed, with the lesion arising from the internal anal sphincter. In the second case, endoscopic full thickness resection was performed due to surface ulceration. The video highlights the importance of choosing the appropriate resection technique based on the morphology of the lesion. Technical modifications such as simultaneous digital palpation and mucosal marking were implemented to preserve the external anal sphincter. These procedures aim to achieve clear margins while minimizing morbidity.
