Methods: Descriptive, correlational and systematic study, based on an electronic bibliographic search in scientific databases, of articles published in high-impact journals, in the last 5 years, in English and Spanish, showing relevant information regarding the topic and meet the inclusion criteria, around 50 documents were analyzed, of which 20 were chosen for the writing of this work. Results: Various studies from various countries were found, among which systematic reviews, metaanalyses, prospective studies, surgical protocols and postgraduate theses were analyzed, which showed insignificant results for the specific comparison of staple line reinforcement materials, in instead they offered more information on the benefit of reinforcing, without more specificity of techniques or materials. Discussion: The reinforcement of the staple line is considered by some authors as a prevention technique against the risk of bleeding and leaks, presenting efficacy in a series of patients around some investigations; On the other hand, there are authors who do not consider the reinforcement of the staple line necessary, since no relevant statistics are found on its use, and identify that it is not a procedure that justifies the lengthening of the surgery and the cost of this intervention, something important in a way routine
