Abstract
Background
Thoracoscopic esophagectomy (TE) was reported that increased morbidity in the National Clinical Data analysis in Japan and technical proficiency is required as the esophageal surgery team. The aim of this study is to assess the degree of surgical difficulty from operation time and to applicate for esophageal surgery team-building and the education of next-generation.
Methods
Consecutive initial 33 cases by the same operator was statistically examined concerning the correlation between chest operation time and the empirical effect of the time shortening, BMI, obstructive pulmonary disorders, Rib cage area, tumor progression, preoperative treatment as an indicator of the degree of surgical difficulty. Rib cage area measured in the preoperative CT Imaging.
Results
As the factors affecting the extension of operating time, the narrower upper rib cage area correlated with the prolonged operation time in the univariate (P = 0.0279) and multivariate (P = 0.0125) analysis. Empirical time reduction (P = 0.0429) also was correlated with chest operation time. In addition, there was a significant correlation between chest operation time and blood loss (P = 0.0007).
Conclusion
In the training of TE, operating surgeon or first assistant should start from the patient with broad upper rib cage area in chest CT.
