ENDOSCOPIC SUBMUCOSAL DISSECTION OF A GIANT CIRCUMFERENTIAL LATERALLY SPREADING TUMOR AND CLOSURE

Video Transcription

Video Summary

The video discusses the endoscopic subcausal dissection (EST) of a large, laterally spreading colorectal tumor, highlighting challenges and solutions in its removal and closure. EST offers a less invasive alternative to traditional surgery, minimizing risks like leakage and permanent stoma. The procedure includes multi-tunneling techniques to improve visibility and reduce surgery time while limiting damage. A 51-year-old female patient underwent this procedure for a 15 cm rectosigmoid lesion, resulting in successful removal without cancer presence. The strategy prevents complications such as bleeding and strictures, promoting efficient recovery and no recurrent adverse events over a two-year follow-up.
