BACKGROUND: A subxiphoid surgical approach to thoracic cavity operations has potential advantages such as preventing injuries to intercostal nerves and vessels due to the bypass of the intercostal space during thoracic surgery. The aim of this study was to compare the feasibility and efficacy of the subxiphoid and standard transthoracic approaches for anatomic pulmonary lobectomy in a canine model.
METHODS: Nineteen dogs were assigned for pulmonary lobectomy using either the subxiphoid (n = 10) or standard transthoracic approaches (n = 9). Each group underwent thoracic exploration and anatomic pulmonary lobectomy. Subxiphoid thoracoscopy was performed with a flexible bronchoscope via a 3-cm incision over the xiphoid process. In the conventional thoracoscopy group, approach to the thoracic cavity was obtained through a 3-cm incision over the seventh intercostal space. Physiological parameters (respiratory rate and body temperature) and blood samples (white blood cell counts and arterial blood gases) were collected during the preoperative and postoperative periods. Surgical outcomes data (operating time, operative complications, and body weight gain) were also collected and compared between the groups. The animals were sacrificed 14 d after surgery for necropsy evaluations.
RESULTS: Anatomic pulmonary lobectomy was successfully performed without intraoperative and postoperative complications in all animals. There were no significant differences in the mean operating times or weight gain after surgery between the subxiphoid and the standard transthoracic approach groups. In terms of physiological and pulmonary parameters, there were no observed differences between the two surgical groups for respiratory rate, body temperature, white blood cell counts, and arterial blood gases at any time during the study. Necropsy confirmed the success of lobectomy without complication in all studied animals.
CONCLUSIONS: This study demonstrated that the subxiphoid approach was comparable with the standard transthoracic approach for anatomic pulmonary lobectomy, in terms of feasibility and effectiveness.
