New Trends in Uniportal Video-Assisted Thoracoscopic Surgery for Primary Spontaneous Pneumothorax: A Narrative Review.

Background

Minimally invasive thoracic surgery has advanced since the introduction of multiportal video-assisted thoracoscopic surgery (mVATS) in 1991. Primary spontaneous pneumothorax (PSP) is an ideal condition for refining minimally invasive techniques owing to its straightforward procedures and predictable bullae distributions.

Methods

Uniportal VATS (uVATS), which involves a single incision, is an alternative to mVATS, offering reduced postoperative pain, lower paresthesia rates, and comparable recurrence outcomes. This review explores two main uVATS approaches: intercostal and subxiphoid.

Results

The intercostal approach is common to surgeons trained in mVATS, easier to adopt, and provides excellent cosmetic outcomes. Innovations such as the chest wall pulley method and anchoring sutures further enhance its operability and prevent recurrence. Subxiphoid uVATS minimizes intercostal nerve damage and postoperative pain, making it advantageous for bilateral PSP surgeries. However, it poses challenges such as longer operative times and limited dorsal visualization. Emerging strategies, including drainless postoperative management and two-lung ventilation with CO2 insufflation, have reduced surgical invasiveness. Additionally, cosmetic techniques such as subaxillary incisions enhance patient satisfaction.

Conclusions

uVATS continues to redefine PSP surgery, prioritize patient-centered outcomes, and integrate novel strategies to achieve superior results.
