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

## TL;DR

This case report explores using endoscopic stent placement as a minimally invasive palliative treatment for a rare complication of advanced colorectal cancer.

## Contribution

The paper presents a novel palliative approach using endoscopic stent placement for non-resectable malignant duodenocolic fistulas.

## Key findings

- Endoscopic stent insertion is a safe and minimally invasive palliative option for advanced colorectal cancer patients.
- Correct stent positioning and anchoring may improve clinical outcomes and quality of life.
- Palliative treatment strategies should be individualized and discussed closely with patients.

## Abstract

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.

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.

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.

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.

Malignant duodenocolic fistulas are a serious complication of advanced colorectal cancer.

Advanced colorectal cancer requires palliative alternatives to complete resection.

Endoscopic stent insertion is a minimally invasive and safe palliative treatment option.

Stent insertion offers several significant benefits and can improve quality of life.

Correct positioning, anchoring and measurement of the stent might improve clinical outcome.
