[A Retrospective Study of Microporous Polysaccharide Hemostatic Powder Combined with Other Repair Materials for Reducing Postoperative Pulmonary Air Leakage during Pulmonary Segmentectomy].

BACKGROUND

Anatomical segmentectomy is more and more widely used in lung nodules and early stage lung cancer. Postoperative lung air leakage is one of the common complications after surgery. This study aimed to explore the effect of the application of repair materials in precise segmentectomy under thoracoscopy in reducing postoperative lung air leakage.

METHODS

This study included patients admitted to the Department of Thoracic Surgery of Jiangsu Provincial People's Hospital who were scheduled to undergo thoracoscopic segmentectomy from August 1, 2018 to July 31, 2019. According to the difference of the materials used in the treatment of the inter-segment interface during the operation: patients who used microporous polysaccharide hemostatic powder+fibrin adhesive glue+absorbable polyglycolic acid patch were divided into group A, and the patients with fibrin adhesive+absorbable polyglycolic acid patch were divided into group B. The preoperative basic information of all patients and the daily postoperative chest drainage volume, the indwelling time of the chest drainage tube, the chest radiograph before the chest drainage tube is removed, the chest radiograph after the chest drainage tube is removed, blood routine and postoperative hospital stay were collected and recorded, and the effect of the application of intraoperative repair materials on postoperative lung air leakage was analyzed.

RESULTS

There were statistically significant differences in the indwelling time of thoracic drainage tube (P=0.019) and postoperative hospital stay (P=0.017) between the two groups.

CONCLUSIONS

Compared with the use of the fibrin glue+absorbability polyglycolic acid patch, the use of microporous polysaccharide hemostatic powder+fibrin glue+absorbability polyglycolic acid patch in the treatment of the inter-segment interface during segmentectomy can better reduce the incidence of postoperative air leakage and shorten the postoperative hospital stay.
