Pleurodesis involves inducing an inflammatory reaction between the pleural layers, causing them to adhere and obliterate the pleural space to prevent lung collapse. It can be achieved mechanically through pleurectomy, pleural abrasion, or chemically by instilling a sclerosing agent like talc or doxycycline. Pleurodesis is highly effective in preventing pneumothorax recurrence, with a recurrence rate of 2% [3]. However, it is associated with significant postoperative pain due to pleural inflammation. Extended pain management may be required, and complications can include acute respiratory distress syndrome, infection, and chronic pleuritic pain. Additionally, extensive pleurodesis is irreversible, complicating future thoracic surgeries.

This study suggests no-knife endoscopic stapler blebotomy is a safe and effective alternative for preventing recurrent pneumothorax. The technique demonstrated no recurrences over a median follow-up of 24 months, no postoperative complications, and favorable recovery metrics. Unlike cutting staplers, the no-knife stapler lays down six rows of staple lines, potentially reducing prolonged air leaks. We conjecture that the in situ bleb tissue undergoes necrosis, promoting inflammation at the chest apex and causing natural pleurodesis. There is a legitimate concern that leaving a devitalized tissue may lead to fever, infection, or cause pleuritic chest pain. However, these complications were not observed in any of the patients.

The results have significant clinical implications for managing spontaneous pneumothorax, especially for young, healthy individuals with primary SP who wish to avoid the morbidity associated with painful pleurodesis. This technique may also benefit patients with complications or recurrences from traditional surgical methods. Reduced chest tube placement duration and shorter hospital stays can lead to cost savings and improved resource utilization. Enhanced recovery protocols can further improve patient outcomes and satisfaction. Exploring this technique’s use in secondary spontaneous pneumothorax and complex cases like lung reductions for emphysema could expand its applicability.

While promising, this study has limitations. The retrospective design may introduce selection bias and limit the generalizability of the findings. Prospective randomized controlled trials are needed for more robust evidence of this technique’s efficacy and safety. The small sample size limits the statistical power and ability to detect rare complications or outcome differences. Larger studies with diverse patient populations are necessary to validate these results. Although the median follow-up of 24 months is adequate for short- to mid-term outcomes, longer follow-up is needed to assess the procedure’s durability and late recurrence risk.

In conclusion, no-knife endoscopic stapler blebotomy represents a promising alternative to traditional methods for preventing recurrent pneumothorax. This minimally invasive technique avoids pleurodesis and appears to reduce postoperative pain, shorten hospital stays, and improve recovery outcomes. The absence of recurrences in our study underscores its potential effectiveness. Further research, including larger prospective studies and long-term follow-up, is warranted to confirm these findings and establish this technique as a standard treatment for spontaneous pneumothorax.
