Effect of Dissecting of The Inferior Pulmonary Ligament on Postoperative Pulmonary Reexpansion and Recurrence

Chinese Medical Association260 enrolled

Overview

This subject analysis of the influence of the dissociating inferior pulmonary ligament on pulmonary reexpansion and recurrence in the treatment of primary spontaneous pneumothorax by video assisted thoracic surgery. All patients are randomly divided into two groups: group A and group B. Wedge resection(WR) will be performed for all patients. Investigators dissect the inferior pulmonary ligament(DIPL) for group A. Investigators do not dissect the inferior pulmonary ligament for group B. The pulmonary reexpansion and recurrence rate are observed between the two groups.

Wedge resection of the lung is usually used in the treatment of primary spontaneous pneumothorax. And the pleural treatment also might be used. But part of secondary pneumothorax patients who had undergone surgical, the bullae can be found especially in the apical of lung, even if the pleural have been treated in some way.This subject provides a new way of thinking and method to solve the problem of recurrent spontaneous pneumothorax.
