One-stage closure of large bronchopleural fistula with pedicled latissimus dorsi muscle flap after preemptive antibiotics: A case report

•Bronchopleural fistula (BPF) often needs two-stage closure after fenestration.•This case highlights one-stage surgical closure of a large BPF with a muscle flap.•Pedicled latissimus dorsi muscle flap would be useful even for 3-cm sized BPF.•Preemptive antibiotics minimized local infection in ischemic bronchitis before BPF.•Minimum infection with a limited-size space may be a key for one-stage closure.
