Efficacy of intra-operative unilateral diaphragm plication for patients undergoing unilateral phrenicotomy during extended surgery.

OBJECTIVE: Diaphragm plication is used to improve lung function and respiratory insufficiency in patients suffering from diaphragm paralysis. We assessed the efficacy of intra-operative unilateral diaphragm plication for prevention of postoperative pulmonary complications in patients, who underwent a phrenicotomy due to extended surgical intervention.

METHODS: Intra-operative unilateral diaphragm plication was performed in 13 patients, who underwent a unilateral phrenicotomy during an extended thoracic operation. Six patients had lung cancer, six had a mediastinal tumour and one had a mesothelioma. We retrospectively observed the postoperative clinical courses in the perioperative period and lung function results at 1 year after operation. The postoperative lung function was compared with the predicted postoperative lung function. In addition, we observed clinical symptoms and radiological findings of the follow-up period.

RESULTS: Ten (77%) of the cases revealed no postoperative complications, while three (23%) had pulmonary complications and two (15%) required prolonged mechanical ventilation. Diaphragm paralysis was not shown clinically and radiologically during the follow-up period. Postoperative lung function was similar to predicted postoperative lung function.

CONCLUSION: Unilateral diaphragm plication in a patient undergoing a unilateral phrenicotomy during an extended thoracic operation is effective to prevent postoperative pulmonary complications and to preserve postoperative lung function.
