Clinical Effects of Absorbable and Non-absorbable Suture in Bronchial Sleeve Resection

Lung cancer has been one of the most serious life-threatening diseases of human society. It has the highest morbidity and mortality worldwide among all the malignant tumors. Although the treatment of lung cancer is increasingly diverse, surgical resection is still the mainstay. Pneumonectomy, as a surgical approach for central primary lung cancer, is very harmful to patients. Bronchial sleeve resection is performed as an alternative to pneumonectomy for lung cancer patients with centrally located lesions and limited cardiopulmonary reserve. Intraoperative bronchial anastomosis is very complex and difficult, mainly due to the difficulty of suturing and knotting in limited space. Both absorbable and non-absorbable suture are used for it. But there are currently few studies comparing the clinical effects of absorbable and non-absorbable suture in bronchial sleeve resection. So the investigator wants to conduct a prospective study, trying to figure out this problem. The investigator sets incidence rate of anastomotic complications as the primary endpoint. According to the calculation, a total of 40 patients will be enrolled (each group has 20 patients).
