Our analysis included data of 713 patients from ten departments of surgery. They were divided in non-obese group and obese group with 617 and 96 patients respectively. Significant differences were found in terms of mortality at 90\u00a0days (obese: 0 vs non-obese: 27, <jats:italic>p<\/jats:italic>\u2009=\u20090.037). Intraoperative data showed no significant differences in terms of conversion (obese: 4 vs non-obese: 43, <jats:italic>p<\/jats:italic>\u2009=\u20090.303). About postoperative complications, significant differences between the two groups were found only in terms of surgical infection (obese: 13 vs non-obese: 38, <jats:italic>p<\/jats:italic>\u2009=\u20090.009). About oncological outcomes, no differences were found about retrieved lymph nodes (obese: 30.71\u2009\u00b1\u200918.44 vs non-obese: 32.93\u2009\u00b1\u200917.62, <jats:italic>p<\/jats:italic>\u2009=\u20090.596) and about surgical radicality (R0) (obese:94 vs non-obese:594, <jats:italic>p<\/jats:italic>\u2009=\u20090.415).
