Pulmonary complications are 57% with TTE 27% with THE ( SKF 409)
Anastomotic leak 16% TTE and 14% THE ( not significant) subclinical leak slightly more in THE
Option D is correct
Cardiac complications, Vocal cord paralysis , wound infection, chyle leak are all more with TTE
Blackmon et al. published a propensity-matched analysis comparing outcomes between side-to-side stapled anastomosis, end-to-end circular stapled anastomosis, and handsewn, with no significant difference in leak rate noted. ( SKF page 475)
