    Abstract:
    BACKGROUND: The aim of the present study was to evaluate the effects of preoperative nutritional status on the short-term outcomes of an enhanced recovery after surgery (ERAS) programme for colorectal cancer surgery. METHODS: This prospective observational study included 149 patients who underwent elective resection of colorectal cancer with ERAS from January 2011 to January 2014 in a university hospital. Subjective global assessment (SGA) was used to determine preoperative nutritional status. Primary outcomes included the length of postoperative stay, postoperative morbidity, gastrointestinal recovery, and 30-day readmission. RESULTS: The patients were divided into 3 groups according to the SGA classification. There were 96 patients (64.4 %) in SGA-A (well-nourished), 48 (32.2 %) in SGA-B (mild to moderately malnourished), and 5 (3.4 %) in SGA-C (severely malnourished). Patients in SGA-A had the median length of postoperative stay of 4 days (range 2-23), which was significantly shorter compared to SGA-B (5 days; range 2-16; p < 0.01) and SGA-C (7 days; range 4-17; p < 0.01). The overall complication rates of SGA-A, SGA-B, and SGA-C patients were 11, 31 % (adjusted OR 3.76; 95 % CI 1.36-10.36; p < 0.01) and 40 % (adjusted OR 2.15; 95 % CI 0.07-63.64; p = 0.66). Mean time to resumption of normal diet and time to first defecation were 1.6 ± 1.3 and 2.2 ± 0.9 days in SGA-A, 2.6 ± 1.7 and 3.1 ± 1.6 days in SGA-B (p < 0.01 compared to SGA-A) and 3.2 ± 2.4 days and 2.6 ± 1.5 days in SGA-C (p = 0.07 and p = 0.1 compared to SGA-A, respectively). No 30-day mortality occurred in any group. One patient in SGA-A (1 %), and 3 patients in SGA-B (6 %) had unplanned 30-day re-admission; p = 0.11. CONCLUSIONS: Within an ERAS programme for colorectal cancer surgery, malnourished patients were at risk for increased postoperative morbidity, delayed recovery of gastrointestinal function, and prolonged length of hospital stay.
