t₀: Samples before the procedure; t_end: Samples at the end of the procedure [gastrointestinal endocopy (GI) in control group and double-balloon enteroscopy (DBE) in experimental group]; t_{24 h}: Samples 24 h after the procedure (GI in control group and DBE in experimental group); t_168h: Samples 7 d after the procedure (GI in control group and DBE in experimental group).

P < 0.01 vs control group.
