Double-stapled Colorectal Anastomosis with Beanshaped Rectal Doughnut Eliminating Dog Ears

The double-stapling technique defined by Knight and Griffen in 1980 has found widespread use in colorectal surgery. However, theoretically, the remaining dog ears on each side of the intersecting line between linear and circular stapler lines may have decreased blood supply and may contain tumor cells. Various modifications have been published in the literature to overcome these disadvantages of the double stapling technique. In this article, a modified technique that provides to excise the whole linear stapling line and to not leave the dog ears behind was introduced.
