A modification of single stapled colorectal anastomosis using the transanal insertion device (TAIS).

A modification of single stapled colorectal anastomosis utilizing a reusable stapler head (transanal insertion device [TAIS]) is described. This modification minimizes the time that the proximal bowel is open by allowing early placement of the circular stapler head, and minimizes the risk of rectal injury that may be associated with the passage of a circular stapling device without the head in situ.
