Data are presented as n (%) or median (interquartile range).

¹Mann-Whitney U test for continuous variables, and Pearson’s χ² test or Fisher’s exact test for categorical variables were applied;

²The severity of postoperative complications were classified according to the Accordion Severity Grading System. LSG: Laparoscopic sleeve gastrectomy; LRYGB: Laparoscopic Roux-en-Y gastric bypass.
