The circular stapler has played a critical role in fashioning colorectal anastomoses following low anterior resection for rectal cancer. One of the greatest benefits of the circular stapler has been the feasibility of constructing ultra-low anastomoses, thereby decreasing permanent colostomy rates. A notable US innovation to the original design was the addition of disposable cartridges of various sizes, which greatly decreased assembly time and made the instrument more versatile. Another important modification was the ability to detach the anvil from the stapler shaft. This markedly simplified the construction of anastomoses by negating the need for a double purse-string and avoiding an open rectal stump. An additional modification to facilitate transanal stapler extraction was the tilted-top anvil, which flipped parallel to the shaft once the stapler was fired. The circular stapler continues to evolve while maintaining the basic elements of Hültl's brilliant concept from over a century ago.
