Effects of preoperative oral carbohydrate administration combined with postoperative early oral intake in elderly patients undergoing hepatectomy with acute-phase inflammation and subjective symptom burden: A prospective randomized controlled study
Abstract
Background: Enhanced recovery after surgery (ERAS) has received increasing attention. Preoperative oral carbohydrate and postoperative early oral feeding (POC-PEOF) as the basic nutrition administration in the ERAS program suffers from low adherence. The role and benefits of administering POC-PEOF in elderly patients with hepatocellular carcinoma (HCC) are unclear. Therefore, the randomized controlled trial evaluated the effects of POC-PEOF in elderly patients with HCC undergoing hepatectomy with inflammation and patient self-reported symptom burden compared with the corresponding outcomes of traditional fasting protocols. Methods: Elderly patients with HCC (n = 126) were randomly assigned to two groups using the sealed envelope technique. Sixty-three patients were included in the intervention (POC-PEOF) group and received POC-PEOF administration, whereas the 63 patients in the control (FAST) group underwent conventional fasting. Acute-phase inflammation markers, patient self-reported symptom burdens, and postoperative outcomes were compared between the two groups. Results: The average age was 69.60 ± 5.00 years in the POC-PEOF group and 70.44 ± 6.15 years in the FAST group. Compared to prolonged fasting, POC-PEOF achieved significant positive results, including lower overall levels of inflammatory response mediators (CRP, IL-6) on postoperative day (POD) 1, POD 3, and POD 5 (P < 0.05), lower patient self-reported symptom burdens of thirst, hunger, anxiety and nausea (P < 0.05), faster gastrointestinal function return with shortened times to first flatus and first defecation (48.31 ± 13.24 h vs. 96.26 ± 23.12 h and 72.87 ± 21.12 h vs. 144.34 ± 23.31 h, and P = 0.034 and P = 0.013, respectively). Furthermore, the average postoperative hospitalization duration in the POC-PEOF group was shorter than that in the FAST group (6.93 ± 0.98 d vs. 8.12 ± 1.15 d, P = 0.042). There was no significant difference of total complications between the groups (25.39 % vs 36.51 %, RR 0.696, 95 % CI 0.408–0.187, P = 0.177). Conclusion: POC-PEOF helps lessen acute-phase inflammation and relieves the subjective symptom burden, which can ensure better positive postoperative outcomes in elderly HCC patients undergoing hepatectomy.
