摘要

Background

Gastropleurocutaneous fistula (GPCF) is a rare, potentially life-threatening condition defined by an abnormal connection between the stomach and the pleural cavity with an accompanying cutaneous tract. It is distinct from a gastropleural fistula, which lacks an external cutaneous extension. To our knowledge, no prior reports have described GPCF caused by migration and erosion of a cement chest-wall prosthesis.

Case presentation

We present the case of a 40-year-old female with a history of anterior chest wall sarcoma resection and cement prosthesis reconstruction performed 23 years earlier. The patient developed a chronic cutaneous discharge beneath the left breast and was ultimately diagnosed with a gastropleurocutaneous fistula. Although she had experienced prior episodes of discharge, this was the first time the condition was confirmed through imaging and intraoperative findings. Imaging revealed a large left thoracoabdominal collection and erosion of the diaphragm by the prosthesis into the gastric fundus. Surgical management included isolation and stapling of the gastric fistula, diaphragmatic repair using polypropylene mesh, and pleural cavity debridement.

Case discussion

The development of gastropleurocutaneous fistula secondary to cement prosthesis migration has not been previously documented. While cement-based prostheses offer structural stability, long-term complications such as erosion into visceral organs may occur, particularly with inadequate fixation or soft tissue coverage. Diagnosis requires a high index of suspicion and a combination of radiological and endoscopic modalities. Surgical repair remains the definitive treatment, often requiring a combined thoracoabdominal approach.

Conclusion

This case highlights a rare but serious late complication of chest wall reconstruction with cement prosthesis. It underscores the need for long-term surveillance in patients with synthetic implants and the importance of individualized surgical planning in managing complex thoracoabdominal fistulas.
