Abstract:

Objective To study the factors of persistent cough after pulmonary resection (CAP) in patients with lung cancer after thoracoscopic lobectomy. Methods A retrospective analysis had been conducted with clinical data of 570 patients (163 cases in CAP group and 407 cases in non-CAP group) with lung cancer who underwent surgery in the Department of Thoracic Surgery of He’nan Provincial People’s Hospital from April 2017 to October 2019, including gender, age, BMI, smoking history, surgical side (left or right), surgical lobe site (upper lobe or not), anesthesia time, dissected peritracheal lymph nodes, pathological types, postoperative pleural effusion and/or pneumothorax. The factors of CAP were examined through univariable and multivariable logistic regression. Results The occurrence rate of CAP was 28.60% (163/570) among 570 lung cancer surgery patients. Univariable analysis showed that the occurrence rates of CAP among patients with age <60 years, BMI ≥24.28, no smoking history, right surgical side, upper lobe surgery, anesthesia time ≥196.36 min, no peritracheal lymph node dissection and without postoperative pleural effusion/pneumothorax (32.34% (109/337), 33.33% (86/258), 33.33% (91/273), 33.93% (113/333), 34.11% (117/343), 35.68% (71/199), 29.85% (157/526), 36.11% (52/144)) were higher than those with age ≥60 years, BMI<24.28, smoking history, left side surgery, surgery outside upper lobe, anesthesia time <196.36 min, peritracheal lymph node dissection and postoperative pleural effusion/pneumothorax (23.18% (54/233), 24.68% (77/312), 24.24% (72/297), 21.10% (50/237), 20.26% (46/227), 24.80% (92/371), 13.64% (6/44) and 26.06% (111/426)). The differences were statistically significant (χ2 values were 5.671, 5.179, 5.757, 11.174, 12.826, 7.510, 5.226 and 5.329, respectively, P values were 0.017, 0.023, 0.016, 0.001, 0.001, 0.006, 0.022 and 0.021, respectively). Multivariable logistic regression analysis showed that age ≥60 years (OR=0.616, 95%CI: 0.424-0.895) and smoking history (OR=0.656, 95%CI: 0.432-0.997) were protective factors for CAP; BMI<24.28 (reference: BMI ≥24.28; OR=1.814, 95%CI: 1.241-2.652) and right side surgery (reference: left; OR=3.601, 95%CI: 1.695-7.561), upper lobe surgery (reference: outside upper lobe; OR=1.114, 95%CI: 1.020-1.217), anesthesia time ≥196.36 min (reference: <196.36 min; OR=1.789, 95%CI: 1.214-2.636), and peritracheal lymph node dissection (reference: no dissection, OR=2.730, 95%CI: 1.126-6.622) were risk factors of CAP. Conclusion Patients with age <60 years, BMI<24.28, no smoking history, right side surgery, upper lobe surgery, anesthesia time ≥196.36 min, and peritracheal lymph node dissection have higher risk of CAP after surgery.
