    Objective: To describe morbidity and mortality associated with colorectal prostheses (CP) and identify factors associated with their complications during the 2007 to 2022 at INDISA Clinic. Material and Method: Retrospective cross-sectional study based on clinical registry. Results: 49 CPs were installed with 100% clearing success. 87.8% in left colon. The main etiology was malignant 91.8% and 85.7% were primary colorectal. 34 were installed with palliative intention, 12 as a bridge to elective surgery (BTS) and 3 for benign pathology. There were 13 (26.5%) patients with adverse effects (7 strictures, 4 perforations and 2 migrations). Associated mortality was 4.1% (2 patients). The complicated group was younger, with more advanced oncological stages and rectosigmoid stenosis (p < 0.005). Those under 50 years of age had 5 times higher risk of some complication (OR = 5.0; 95% CI: 1.09-23.0; p = 0.039). Discussion: The use of CPs has low short-term morbidity and mortality. Its main use is as palliative treatment or BTS in malignant colorectal obstruction. It’s a high clearance rate. It is associated with less morbidity than emergency surgery, a lower ostomy rate, and a higher lymph node harvest. Installation as a bridge is also associated with a higher rate of primary anastomosis. Our group showed a higher complication rate in those with advanced and younger tumors. Conclusion: The use of CPs is safe, with low morbidity and mortality. The main indication is in obstructive colorectal neoplasia as palliative treatment. Young patients and advanced colorectal tumors with peritumoral nodes have a higher risk of complications. © 2024, Sociedad de Cirujanos de Chile. All rights reserved.
