Background: Complex pelvic tumors and fistula-in-ano present challenging anatomical pathologies that can hinder successful surgical outcomes. Three-dimensional (3D) printed anatomical models can improve the accuracy and outcome of surgical treatments, while serving as tools for medical and patient education. This study aims to review existing literature on the application of 3D printing in colorectal surgery, with a special focus on complex pelvic tumors and fistula-in-ano. Additionally, a brief discussion of our initial experience in utilizing 3D printed models is included. Methodology: A literature review was conducted using MEDLINE/PubMed to identify randomized controlled trials (RCTs), retrospective studies, and technical reports. Five 3D-printed anatomical models were manufactured for colorectal surgeons in our center. AI was not used in the research and manuscript development. Results: A total of seven articles were identified, revealing the utility of 3D printing for improving current and future surgical management of complex pelvic tumors and fistula-in-ano through improved pre-operative planning and medical education. In addition, our initial experience exemplified the usefulness of 3D-printed anatomical models for enhancing pre-operative planning, intra-operative navigation, and patient education. Conclusion: Existing literature and our single-center experience highlight the role of 3D printing in improving the management of complex pelvic tumors and fistula-in-ano. Larger and more well-designed studies looking into operative and financial outcomes, as well as patients’ and surgeons’ experiences, may be required to further justify its clinical utility and fidelity.
