All complications in the D2 Lymphadenectomy and D2 Lymphadenectomy plus complete mesogastric excision group were Clavien-Dindo grade I-II and managed conservatively. In the D2 Lymphadenectomy group, five patients developed grade III-IV complications requiring surgical or interventional procedures. D2: D2 Lymphadenectomy; D2 + CME: D2 Lymphadenectomy plus complete mesogastric excision.
