[Do thoracic surgery patients always need a postoperative chest X-ray?]

Area of Science:

• Thoracic Surgery
• Diagnostic Imaging
• Evidence-Based Medicine

Background:

• Postoperative chest X-rays are standard after thoracic surgery but their necessity, especially after minor procedures like mediastinoscopy, is often unquestioned.
• Practices vary regarding the timing of these X-rays, with some institutions performing them immediately post-procedure and others the following day, while some rely solely on clinical examination.

Purpose of the Study:

• To evaluate the necessity of routine postoperative chest X-rays following video-mediastinoscopy.
• To determine if chest X-rays can be safely omitted in favor of clinical examination after this procedure.

Main Methods:

• A prospective randomized study involving 95 consecutive patients undergoing video-mediastinoscopy.
• Patients were divided into two groups: one receiving a chest X-ray four hours postoperatively, and the other undergoing only clinical examination.

Main Results:

• 52% of patients did not receive a postoperative chest X-ray and were managed with clinical examination alone.
• No surgical revisions were required in either group, and there were no observed differences in therapeutic consequences.
• The study led to the discontinuation of routine chest X-rays after mediastinoscopy.

Conclusions:

• Sparse data exists on postoperative chest X-rays in thoracic surgery, but existing studies suggest routine imaging may not be indicated.
• Studies in pediatric cardiac surgery and after drain removal indicate that on-demand or clinically indicated imaging is sufficient, without impacting outcomes.
• Based on this study's findings, routine postoperative chest X-rays are no longer performed after mediastinoscopy, with patients managed clinically.
