Compared with the conventional care group, patients of FTS group had shorter postoperative hospital stay [WMD = -1.85, 95%CI: (-2.60, -1.11), P < .00001], earlier first flatus [WMD = -9.33, 95%CI: (-13.74, -4.91), P < .0001], lower level of C-reactive protein (CRP) at postoperative day 4 [WMD = -13.94, 95%CI: (-22.74, -5.15), P = .002], and less hospitalization fees [SMD = -1.12, 95%CI: (-2.07, -0.18), P = .02].
The results showed that in the FTS group, latency to the first postoperative flatus (1.5 ± 0.6 versus 3.1 ± 0.8 s in controls, P < 0.0001), CRP (71.36 ± 5.48 versus 80.71 ± 8.32 mg/L in at POD 7, P < 0.0001), the length of hospital stay (18.1 ± 1.4 versus 27.4 ± 6.6 days, P < 0.0001), and the medical costs (29.9 ± 2.7 versus 37.2 ± 3.6 thousand Chinese Yuan, P < 0.0001) were significantly reduced compared to the group receiving conventional management.
