Aim: There is scant evidence regarding surgical outcomes of patients with colon cancer in Latin America. The aim of this work was to compare perioperative (30 day) outcomes of patients undergoing surgery for right colon cancer in Latin America based on centre volume. Method: This is a multi-institutional retrospective cohort study. Individuals operated on for right colon cancer with curative intent in an urgent or elective setting between 2016 and 2021 were eligible for inclusion in the study. Patients were divided into two groups according to whether they were operated on in low-volume or high-volume centres (defined as more than 30 cases/year). Results: A total of 2676 patients from 46 hospitals in 11 countries of Latin America were included, with 389 (14.5%) in the low-volume group. The median age was 67.37 years. The high-volume group presented higher rates of laparoscopic procedures (56.8 vs. 35.7%, p < 0.001, OR 2.36), with lower conversion rates, fewer intraoperative complications and a shorter operating time. The high-volume group had a shorter length of hospital stay. The overall complication rate for the whole group was 15.9%, with a lower incidence of these events in the high-volume group (13.7 vs. 28.7%, p < 0.001, OR 0.40). Overall, anastomotic leakage, reoperation and mortality rates were 5.6%, 9.2% and 6.1%, respectively, with differences favouring high-volume centres. On multivariate analysis, low-volume group, history of cardiac disease, emergency surgery, operation performed by a general surgeon, open approach and intraoperative complications were independent predictors of major postoperative complications. Conclusion: This is the first study in Latin America to show better postoperative outcomes at a regional scale when surgery for right colon cancer is performed in high-volume centres. Further studies are needed to validate these data and to identify which of the factors can explain the present results.
