Compared with conventional care group, FTS group relates to shorter postoperative hospital stay (WMD - 2.16; 95% CI - 3.05 to - 1.26, P < 0.00001), less cost of hospitalization (WMD - 4.72; 95% CI - 6.88 to - 2.55, P < 0.00001), shorter time to first flatus (WMD - 9.72; 95% CI - 13.75 to - 5.81, P < 0.00001), lower level of C-reaction protein on postoperative days 3 or 4 (WMD - 19.66; 95% CI - 28.98 to - 10.34, P < 0.00001), higher level of albumin on postoperative day 4 (WMD 3.45; 95% CI 2.01 to 4.89, P < 0.00001), and postoperative day 7 (WMD 5.63; 95% CI 1.01 to 10.24, P = 0.02).
