Un algoritmo para la colocación de malla profiláctica en pacientes de riesgo reduce la incidencia de hernia incisional tras laparotomía por cáncer colorrectal

Abstract

ObjectiveIncisional hernia (IH) after colorectal surgery is highly prevalent. The objective of this study is to assess the utility of an algorithm to decide on mesh augmentation after a midline laparotomy for colorectal resection to prevent IH in high-risk patients. MethodsA prospective study was conducted including all patients undergoing a midline laparotomy for colorectal resection between January 2011 and June 2014, after the implementation of a decision algorithm for prophylactic mesh augmentation in selected high-risk patients. Intention-to-treat analyses were conducted between patients in which the algorithm was correctly applied and those in which it was not. ResultsFrom the 235 patients analysed, the algorithm was followed in 166 patients, the resting 69 cases were used as a control group. From an initial adherence to the algorithm of 40% in the first semester, a 90.3% adherence was achieved in the seventh semester. The incidence of IH decreased as the adherence to the algorithm increased (from 28 to 0%) with a time-related correlation (R2=0.781). A statistically significant reduction in IH incidence was demonstrated in high-risk groups in which the algorithm was correctly applied (10,2 vs. 46,3%; p=0,0001; OR: 7,58;95%; CI: 3,8-15). Survival analysis showed that the differences remained constant during follow-up. ConclusionThe implementation of the algorithm reduces the incidence of IH in high-risk patients. The adherence to the algorithm also correlates with a decrease in the incidence of IH.
