Video Tip: Diagnosing a Type 3 Muscle Injury | October 2022-Diagnosing a Type 3 Muscle Injury

Video Transcription

Video Summary

In this video, an endoscopic mucosal resection (EMR) of a lateral spreading lesion in the ascending colon is being performed. The lesion is grasped and released using a snare, and then re-grasped for transection. A section of the lesion has not been removed yet, and there is a depression area with white bands along the top. The correct answer to what happened during this EMR is a type 3 muscle injury, where the muscle is cut and seen as parallel white bands. It is important to recognize and reinforce this injury to prevent a delayed perforation, usually by using clips. This video tip is sponsored by an educational grant from Braintree, a part of Cibela Pharmaceuticals, makers of SUTAB.
