Since biliary tract external drainage (BTED) is increasingly used to treat patients with shock, it is necessary to clarify pathophysiological changes following BTED in hemorrhagic shock (HS). The present study aimed to investigate the effect of BTED on farnesoid X receptor (FXR) and Takeda G‑protein coupled receptor 5 (TGR‑5) expression in HS. A total of 24 Sprague‑Dawley rats were randomly allocated to sham, BTED, HS and HS + BTED groups. Rat models of HS were induced by drawing blood from the femoral artery until a mean arterial pressure of 40±5 mmHg was achieved and maintained for 60 min. Rat models of BTED were induced by inserting a catheter into the bile duct. The distal end of the bile duct was ligated, and the catheter was passed through the rat flank to allow external collection of bile. Reverse transcription‑quantitative PCR, western blotting and immunohistochemistry were performed to detect changes in expression levels of FXR and TGR‑5 in the jejunum, ileum and liver. Expression levels of FXR and TGR‑5 increased significantly in jejunum and liver following HS (P<0.05). BTED significantly decreased expression levels of FXR in the liver (P<0.05) and TGR‑5 in the jejunum, ileum and liver (P<0.05). In conclusion, expression levels of FXR and TGR‑5 increased in HS but BTED decreased expression levels of FXR and TGR‑5 in HS.
