Use of circular stapling gun with peranal insertion of anorectal purse-string suture for construction of very low colorectal or colo-anal anastomoses

A technique is described for construction of the colorectal or colo-anal anastomosis in low rectal resection by using an automatic circular stapling device and inserting the anorectal purse-string suture peranally from below. This method was employed in 4 patients resulting in complete healing in 3 cases and a moderate leak in 1, which, however, eventually healed satisfactorily.
