Fast-track improves post-operative nutrition and outcomes of colorectal surgery: a single-center prospective trial in China

Fast-track (FT) has been shown to enhance post-operative recovery. The aim of this study was to compare the effects of FT and traditional nutrition on post-operative rehabilitation, as well as evaluate the feasibility of applying FT in nutrition management of colorectal surgery. A prospective and randomized controlled trial was performed. This study included 464 patients who underwent colorectal surgery. The patients were randomly assigned into an FT group and a traditional group. The nutritional risk screening (NRS 2002) score, post-operative recovery index and surgical complications were compared between the FT and traditional groups. The NRS 2002 score in the FT group was better than the traditional group (p<0.05). Serum indicators for nutrition (HGB, ALB, A/G) and immune function (lymphocyte rate [LYMPH%], IgA, and CD4+) in the FT group were superior to those in the traditional group (p<0.05) on post-operative day 5. The first time to aerofluxus, defecation, oral intake and ambulation in the FT group was shorter when compared to the traditional group (p<0.05). The complication incidence was significantly lower in the FT group than in the traditional group (p<0.05). In particular, the occurrence rate of anastomotic leakage was higher in the traditional group than in the FT group (0.5% vs 2.8%, p<0.05). Taken together, these data suggest that FT management can improve the nutritional condition and outcomes of colorectal surgical patients.
