The Video-Assisted Thoracic Surgery for Mediastinal Bronchogenic Cysts: A Single-Center Experience.

Area of Science:

• Thoracic Surgery
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Mediastinal bronchogenic cysts (MBCs) are congenital abnormalities requiring surgical management.
• Accurate diagnosis and complete excision are crucial for preventing complications.

Purpose of the Study:

• To evaluate the outcomes of video-assisted thoracic surgery (VATS) for MBC excision.
• To investigate surgical indications and factors influencing MBC excision outcomes.

Main Methods:

• Retrospective review of 119 consecutive MBC patients undergoing surgical excision (2001-2016).
• VATS was the primary surgical approach, with complete cyst resection as the goal.
• Follow-up conducted annually via telephone or outpatient clinic.

Main Results:

• 118 patients underwent VATS; one conversion to open thoracotomy.
• Average operative time: 103.8 min; average blood loss: 56.6 ml.
• Maximal diameter >5 cm significantly correlated with increased operative time and blood loss (p<0.05).
• No serious postoperative complications; no local recurrence observed in 102 patients with a mean follow-up of 45 months.

Conclusions:

• VATS is a safe and effective approach for MBC excision.
• Early surgical intervention is recommended to establish diagnosis, alleviate symptoms, and prevent complications.
• Cyst size >5 cm is a risk factor for prolonged operation and increased bleeding.
