Pdf Summary

This presentation discusses a retrospective study on the methods of covering the bronchial stump/anastomotic site to avoid bronchopleural fistula (BPF) after lung cancer surgery. BPF is a serious complication that can occur after lung resection, especially in patients who undergo induction chemoradiotherapy (iCRT) for locally advanced non-small cell lung cancer (LA-NSCLC). To prevent BPF, surgeons often cover the bronchial stump or anastomotic site with surrounding tissue. The aim of this study was to determine which type of tissue flap is most effective in preventing BPF.<br /><br />The study included 182 patients with LA-NSCLC who underwent radical resection after iCRT between 1999 and 2019. Out of these, 152 patients were included in the analysis after excluding cases where the bronchial stump or anastomotic site was not covered. The researchers examined the clinicopathological characteristics of the patients, including the type and thickness of the tissue flap used for covering, as well as postoperative complications.<br /><br />The results showed that BPF occurred in five patients (3.3%). All five patients had complications that could affect delayed wound healing, such as pneumonia. The bronchial stump/anastomotic site was covered with different types of tissue, including pericardial fat pad, intercostal muscle, and omentum. The thickness of the covering tissue was significantly greater in cases where BPF did not occur, despite a high risk of BPF, compared to the five cases with BPF.<br /><br />The findings suggest that perioperative management is important to avoid complications affecting the healing of the bronchial stump/anastomotic site. In cases where complications do occur, the thickness of the covering tissue may be an important factor in avoiding or minimizing BPF. This study provides insights into best practices for preventing BPF after lung cancer surgery in patients with LA-NSCLC who undergo iCRT.
