This video fully demonstrates all the technical aspects of performing sentinel node biopsy in the sigmoid mesocolon by NOTES. A transgastric access to the peritoneum allows a flexible gastroscope observe the lymphatic mapping in real-time and then to perform excisional nodal biopsy while magnetic retraction provides full exposure of the sigmoid mesentery. Such a totally NOTES procedure could be used to supplement colonoscopic intraluminal dissection (e.g. ESD) or prompt transmural localized resection (perhaps also by NOTES).
