There was no statistically significant difference in the diversity of gut microbiota between baseline and 2 weeks after surgery among the three groups. A–E α diversity (Ace, PD whole tree, Sobs, Chao, and Simpson diversity) of gut microbiota at baseline in each group. F–G α diversity (Ace, PD whole tree, Sobs, Chao, and Simpson diversity) of gut microbiota in each group at 2 weeks after surgery. K, L Genus level of β diversity at baseline (left) and 2 weeks after surgery (right). n = 4–5 per group. Data were presented as mean ± SEM. Statistics were analyzed using one-way analysis of variance (ANOVA) and followed by Fisher’s least significant difference (LSD) test. ns no statistical difference
