P1.08-009 - Does Body Mass Index (BMI) Affect Outcomes Post Lung Resection Surgery? (ID 5082)
14:30 - 14:30 | Author(s): S. Avtaar Singh
- Abstract
Background:
Increased BMI increases the surgical risk, atelectasis and postoperative complications in patients considered obese (BMI≥30). Several published studies have shown a protective effect of increased BMI. The introduction of Enhanced Recovery Programmes (ERP) in surgical units has greatly benefited obese patients in other surgical specialties but its impact in patients undergoing thoracic surgery is uncertain. We looked at the outcomes of patients at our unit since its implementation.
Methods:
A retrospective cohort study was performed on all patients undergoing first time lobectomies for primary lung cancer between January 2015-June 2016. Patients with BMI<18 were excluded from the study. Student’s T-test, Mann-Whitney-U Test and Chi-Squared analysis was used for statistical analysis of demographics and outcomes.
Results:
Figure 1 Preoperatively, the FEV1 and DLCO were both significantly higher in patients with BMI≥30. There were no statistically significant postoperative differences between the two groups.
Conclusion:
Patients with a BMI≥30 can do just as well as patients with BMI<30 in an ERP for patients with lung cancer undergoing lobectomy.

P1.08-016 - BMI in Patients with Operated Lung Cancer in Comparison with the Scottish Health Survey 2014. Is There a Democracy in BMI? (ID 4388)
14:30 - 14:30 | Author(s): S. Avtaar Singh
- Abstract
Background:
Lung cancer has the most common cancer related mortality in Scotland¹. Malnutrition is common in these patients and may affect survival². However many patients with operable lung cancer are overweight³. We looked at lung cancer resection rates at our unit and compared it to the Scottish Health Survey (SHS) 2014.
Methods:
A retrospective cohort study of all patients undergoing lobectomy and pneumonectomy for pathologically proven primary lung cancer from April 2012 to May 2016.
Results:
5833 patients have been operated in our centre during the period, 1882 had anatomical lung resections and 979 of these were eligible to enter our study. Mean age of male patients was 68±9.5 years and female patients was 66.7 ±9.0 years. The median length of stay for males and females were 8 (Q1=6, Q3=12) and 7 (Q1=6, Q3=10) days respectively. The Chi squared test for trend for males showed X²(1) =0.07, 2p=0.8, females showed X²(1) =0.00, 2p=1.0. There was no statistical difference for both males and females BMI distribution between the SHS and our cohort.
Figure 1BMI males females <18.5kg/m² 8 15 18.5-24.9kg/m[2] 106 155 25-29.9kg/m[2] 146 135 30-39.9kg/m[2] 90 123 >40kg/m[2] 1 13 total *BMI not recorded (missing data) 351 89 441 98
Conclusion:
Our study reveal that the rate of resection in our cohort was similar to the SHS. Further studies will be required to look into the relationship between surgical outcomes and BMI.

P1.08-040 - Lymph Node Sampling in 3-Port Video Assisted Thoracoscopic Surgery (VATS) vs Uniportal VATS (ID 5083)
14:30 - 14:30 | Author(s): S. Avtaar Singh
- Abstract
Background:
VATS is fast overtaking thoracotomy as the approach to lobectomies due to faster recovery times. Uniportal VATS lobectomies are slowly becoming more popular throughout the world but the advantages of Uniportal VATS over the standard 3-port approach is unclear. The lung resection can often be performed via a Uniportal approach although concurrent lymphadenectomy/lymph node sampling, may be more challenging. We explored the adequacy of lymph node sampling at our unit as per the ESTS 2006 guidelines on intraoperative lymph node staging.
Methods:
All Primary Lung cancers (Non-small cell lung cancers) performed by 4 VATS surgeons from May 2015-July 2016 were included in the study. A single surgeon performed all the Uniportal VATS lobectomies. The standard 3-port approach was employed by 4 VATS surgeons. Patient demographic details and length of stay were obtained from our Cardiothoracic Database (CaTHi) alongside pathological findings.
Results:
Figure 1 The patients in the standard cohort had a higher ThoracoScore indicating increased risk of surgery. There was no statistically significant demographic difference between the two groups. The rate of lymph node dissection was similar in both groups.
Conclusion:
Despite the perceived limited access, uniportal VATS has shown to be as good as standard 3 port VATS for lymph node sampling intraoperatively.
