NCT02558608

Brief Summary

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.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • The patients diagnosis pneumothorax with chest radiograph or computed tomography (CT)
  • The clinical and final pathological diagnosis for patient is PSP.
  • The patients with stable vital signs, no contraindication for operation and no communication barriers.
  • The patients,after informed of test content, significance and risk, who voluntarily enroll and sign informed consent.

You may not qualify if:

  • The patients who refuse to do a video assisted thoracic surgery.
  • The patients with pneumothorax with specific causes such as pulmonary hamartoangiomyomatosis, catamenial pneumothorax, and pneumothorax secondary to chronic obstructive pulmonary disease.
  • The patients who were older than 50 years
  • The patients with familial history of pneumothorax.
  • The patients with mental disorders, low Intelligence Quotient, can not objectively reflect the indicators of observation.
  • The patients who refuse to follow-up.
