¹The tumor stage of the patients was judged according to the 7th edition of American Joint Committee on Cancer staging manual[8];

²Complications are defined as none = 1, infection = 2, fistula = 3, others = 4, and postoperative outcome as recovery = 1, no recovery = 2, death = 3, for easier statistical presentation of the results. NS: Nutrition support; NNS: Non-nutrition.
