[Double stapler technique in colorectal surgery].

Background: Colorectal surgery has evolved significantly during the last 35 years. The circular stapler and the double stapler techniques have favored the development of very low rectal anastomoses with reduction in anastomotic leakage. The objective of this study is to evaluate the functional results and complication rate of this surgical technique in the Department of Colorectal Surgery at the Hospital de Especialidades, Centro Medico Nacional Siglo XXI and at the Hospital Angeles del Pedregal, both located in Mexico City.
