Diagnosing a Type 1 Muscle Injury

Video Transcription

Video Summary

In this video, we see the aftermath of two procedures: an endoscopic mucosal resection using traditional EMR and an on block resection of a serrated lesion. The white area in the center of the EMR defect represents type 1 muscle injury, which is not really an injury but rather the exposure of the muscle. The rest of the semicosal defect is stained blue, indicating typical staining. Closing the type 1 muscle injury is not always necessary, but if the muscle is believed to be injured, it can be closed using hemostatic clips or other devices.
