Palliative management of malignant duodenocolic fistula: Case report on endoscopic duodenal stent placement and its clinical implications.

Introduction and importance: Malignant duodenocolic fistulas are a rare but serious complication of advanced colorectal cancer. With the growing elderly population and increasing incidence of advanced colorectal cancer, there is a pressing need to explore palliative alternatives to complete resection, especially when a patient's overall health precludes extensive surgery.

Case presentation: This case report presents a palliative approach involving luminal stent placement via gastroscopy in a patient with non-resectable, locally invasive colorectal cancer, resulting in a malignant duodenocolic fistula.

Clinical discussion: We discuss different palliative treatment strategies against malignant duodenocolic fistulas, including endoscopic luminal stent placement and specific technical aspects of this procedure, highlighting factors that may contribute to a successful clinical outcome.

Conclusion: Endoscopic stent placement can represent a minimally invasive palliative strategy to provide symptom relief in a patient with advanced colorectal cancer. Treatment strategy should be considered on a individual basis and in close consultation with the patient.
