    Abstract:
    OBJECTIVE: Bronchopleural fistula is a serious complication of pulmonary resection. For anatomical reasons, lower lobectomy is thought to carry a higher risk for bronchopleural fistula. We investigated the efficacy of bronchial stump reinforcement with a pedicled intercostal muscle flap after lower lobectomy and compared the responses in patients treated with the flap, without the flap, and with other types of flap. We also investigated whether harvesting the intercostal muscle flap leads to an increase in blood loss during surgery and whether the type of flap influences chest-tube volume and pain after surgery. METHODS: One hundred and sixty-eight patients had lower or middle-lower lobectomy between January 1990 and December 2004. The bronchial stumps were treated in one of the three ways: covered with an intercostal muscle flap (116 patients, group A), not covered with a muscle flap (32 patients, group B), or covered with free fat or pleura (20 patients, group C). In a separate study, we compared the blood loss during surgery, and chest-tube volume and pain after surgery between patients treated with the intercostal muscle flap (23 patients) and non-intercostal muscle flap (32 patients). RESULTS: No patients in group A exhibited bronchopleural fistula, and two patients in group B and one patient in group C exhibited bronchopleural fistula. These differences were not significant. Blood loss, chest-tube volume, and pain score after surgery did not differ significantly between treatment groups. CONCLUSIONS: Bronchial stump reinforcement with the intercostal muscle flap after pulmonary resection is safe and effective when performed during lower and lower-middle lobectomy and does not increase the risk of complications.
