P1.16-021 - Midterm Oncologic Outcomes of Single Port Thoracoscopic Lobectomy for Lung Cancer by Propensity Matched Analysis (ID 10087)
09:30 - 09:30 | Presenting Author(s): Kook Nam Han
- Abstract
Background:
Current evidence is still weak to establish the oncologic equivalence of single port thoracoscopic approach compared to conventional multiport thoracoscopic surgery as one of minimally invasive approach for lung cancer surgery. The purpose of this study is to evaluate the midterm surgical outcomes of single port approach compared to conventional multiport approach in thoracoscopic lobectomy for lung cancer.
Method:
A total of 228 patients in propensity matched group (both 114 patients with pathologic stage I who underwent lobectomy by conventional multiport or single port VATS) were compared the operative outcomes and we analyzed midterm survival and recurrence to evaluate the feasibility of single port VATS lobectomy for lung cancer.
Result:
Both propensity matched groups showed comparable preoperative variables (age, gender, FEV~1~, and tumor size) (Table 1). The mean operation time, the number of resected lymph node, and conversion to open thoracotomy or multiport VATS in both group did not show differences (respectively, P=0.076, P=0.291, P=0.253). There was no difference in postoperative major morbidity (P=0.807) and 30-day mortality (p=0.247). The duration of chest drain was shorter in single port VATS group (p<0.001) (Table 2). The survival (P=0.258) and freedom from intrathoracic recurrence (p=0.797) for mean 32 (6-62) months follow up in patients with pathological stage I were not statistically different between groups (Fig). Figure 1
Conclusion:
Single port thoracoscopic lobectomy in lung cancer showed acceptable oncologic outcomes for midterm follow ups with oncologic equivalence compared to conventional multiport thoracoscopic lobectomy.

P3.16-020 - Long Term Changes of Pulmonary Function After Lobectomy (ID 10079)
09:30 - 09:30 | Presenting Author(s): Kook Nam Han
- Abstract
Background:
Postoperative pulmonary function changes after lung resection and that decline is determined by the extent of lung resection. It has been known that pulmonary function after surgery recovers gradually within 3 months to 1 year and finally reaches a steady state. However, the long-term respiratory function is unknown. We investigated the changes in respiratory function after thoracic surgery in patients who performed more than segmentectomy to evaluate the long-term effect of lung resection.
Method:
A total of 99 patients who underwent lobectomy followed up serial pulmonary function at postoperative 1month, 6months, 1,2,3 and 5 years. We investigated the serial changes of forced expiratory volume per 1 seconds (FEV~1~%), diffusion capacity of carbon monoxide (DL~CO~%) by groups of minimal invasive surgery and adjuvant chemotherapy.
Result:
The reduced postoperative FEV~1~% recovered to preoperative value until postoperative 6 to 1 year and declined yearly. The value of DL~CO~% increased to preoperative value until postoperative 2 years and remained steady state. There was no significant change in at more than 2 years follow-up (Fig.1). The value of DL~CO~% was decreased significantly during adjuvant therapy (p=0.031) (Fig.2) and the patients performed VATS lobectomy showed faster recovery in FEV~1~% and DL~CO~% compared to thoracotomy group (p=0.001) (Fig.3 and 4). Figure 1
Conclusion:
The respiratory function after lung lobectomy recovered gradually over postoperative 2 years. Adjuvant chemotherapy or thoracotomy showed negative impact on the postoperative pulmonary function.
