IDENTIFYING THE IMPOSSIBLE PIECEMEAL COLD SNARE RESECTION PERFORATION

Video Transcription

Video Summary

Peacemule-Kolzner resection is gaining popularity for resecting large non-pedunculated colorectal polyps, especially serrated lesions, due to its lower adverse event rate compared to conventional EMR. A case involving a 63-year-old female demonstrates the successful management of a perforation, which is rare with this technique. Despite the low risk, endoscopists should remain vigilant for deep mural injuries. Effective management involves prompt closure using available technologies and careful monitoring. The case underscores the need for standard post-resection evaluations to prevent serious complications, promoting Peacemule-Kolzner resection as a safe, effective method.
