ABSTRACT

Introduction: anastomotic fistulas and unplanned reinterventions are a common problem in oncologic colorectal surgery and generate a significant increase in morbidity, mortality, hospital stay and costs for the health system. Objective: the objective of this study is to describe the frequency of anastomotic fistulas and unplanned reoperation in oncological colorectal surgery in a hospital, over a 3-year time horizon. Material and methods: an observational study was performed focused on patients that underwent surgery as treatment for colorectal cancer, with primary anastomosis in our institution, between January of 2017 and December of 2019, aiming to describe the frequency of anastomotic fistula and reoperations. Descriptive statistics of the variables and bivariate analysis were performed between the outcomes and the main risk factors. Results: in the analyzed period, 2,230 patients underwent surgery in the colon and rectum surgery unit of our hospital center. Of these patients, 150 were taken to oncological colorectal surgery with primary anastomosis. 10 patients (6.7%) presented anastomotic fistula and 21 (14%) needed a re-intervention. Three patients died during follow-up, equivalent to a mortality of 2%. The bivariate analysis did not show statistical significance of any of the risk factors analyzed. Conclusions: anastomotic fistula and re-intervention are both of significant importance in the postoperative evolution of patients undergoing oncologic colon and rectum surgery. These events increase patient morbidity and mortality, length of hospitalization and could be associated with higher costs for the health system. The frequency of these two outcomes in our center are within international recommendations range. The present study did not identify risk factors associated with the outcomes, but the sample size is limited.
