Transanal Notes Sigmoidectomy in a Cadaver Model
Ezra N. Teitelbaum*, Fahd O. Arafat, Byron F. Santos, Eric S. Hungness, Anne M. Boller Surgery, Northwestern, Chicago, IL
This video shows a transanal hybrid natural orifice transluminal endoscopic surgery (NOTES) sigmoidectomy performed in a cadaver model using a TEM proctoscope. We employ a combined laparoscopic and endoscopic technique to place a stapler anvil in the proximal colon prior to initiation of colon dissection. This allows for a completely intra-corporeal anastomosis to be performed without the need for colon exteriorization. Techniques for occluding the rectal lumen with a purse-string suture, performing a full thickness dissection at the rectosigmoid junction, and creating a colorectal anastomosis through the TEM proctoscope are also shown.
