En bloc resection of gastrobronchial fistula associated with mesh infection.

A 50-year-old woman presented with chief complaints of fever and cough. She had a poorly controlled left lung abscess and a history of congenital left diaphragmatic hernia treated 9 years prior with composite mesh. Computed tomography showed suspected fistula formation between the left lower lung lobe and stomach, and the tract was visualized in a contrast study from an upper gastrointestinal endoscope. We suspected a gastrobronchial fistula associated with mesh infection and performed en bloc resection of the mesh and inflamed organ tissue, comprising resection of the left lower lung lobe and left diaphragm, partial gastrectomy, and splenectomy. The diaphragm was reconstructed using the latissimus dorsi and rectus abdominis muscles. To our knowledge, this is the first report describing this treatment strategy for gastrobronchial fistula associated with mesh infection. The patient's postoperative course was favourable.
