Single-stapled colorectal anastomotic techniques: Do not cross the line.

The double-stapled technique is the most common method of colorectal anastomosis. Despite its widespread use, emerging data suggests that this technique may be a risk factor for anastomotic complications, as it is believed that crossing staple lines and resultant dog-ears are potentially weak points that are prone to ischemia and anastomotic leak. Herein, we describe technical variations of single-stapled colorectal anastomoses which surgeons can readily adopt and integrate into their armamentarium of anastomotic techniques.
