ObjectiveTo summarize the current status of research in nutritional support for glutamine after hepatectomy.MethodThe literatures on nutritional support of glutamine after hepatectomy in recent years were reviewed by searching domestic and foreign literatures.ResultsThe administration of glutamine up-regulated the expression of liver regeneration genes after partial hepatectomy in malnourished rats, and then stimulated cell mitosis by paracrine and endocrine cells, affecting the uptake of amino acids by hepatocytes and intestinal cells, and promoting hepatocyte proliferation. In clinical applications, glutamine could improve postoperative liver function and immune function, reduce the incidence of infectious complications, then relatively shorten the length of hospital stay, and improve the clinical outcome of patients.ConclusionGlutamine is beneficial to the recovery of liver function and has clinical application value.
ObjectiveTo systematically evaluate the effect of different enteral nutrition timing on patients with pancreaticoduodenectomy.MethodsPubMed, Embase, The Cochrane Library, Web of Science, CBM, CNKI, WanFang Data, and VIP databases were searched to collect RCTs for nutritional support in pancreaticoduodenectomy patients. The search time was established until March 1 2019. After two independent investigators conducted literature screening, data extraction, and evaluation of the risk of bias in the included studies, a meta-metabolic analysis was performed using the R 3.5.3 software gemtc package, JAGS 3.4.0, and Revman software.ResultsA total of 8 RCTs were included, for a total of 825 patients. The results of reticular meta-analysis showed that there was no significant difference in the duration of hospitalization for patients with pancreaticoduodenectomy, between the enteral nutrition supported at different timing. The results of the ranking probability map suggested that preoperative enteral nutrition was a better option for supporting nutrition in patients with pancreaticoduodenectomy, secondly, timing to give was 24–48 hours after operation.ConclusionsAccording to the results of mesh meta-analysis and probabilistic ranking, the nutritional status of patients is corrected before surgery, and the effect of enteral nutrition is better than other nutritional support methods. Secondly, enteral nutrition should be given at 24–48 hours after operation in combination with ESPEN and ERAS recommendations.
Objective To systematically evaluate safety and effectiveness of using fast track surgery (FTS) protocol in perioperative management of hepatectomy. Methods The studies were collected by searching the PubMed, Web of Science, Cochrane Library, CNKI, Wanfang Data, and VIP databases by two researchers. The FTS management was used in the FTS group and the traditional perioperative management was used in the traditional group. The meta analysis was performed using the RevMan 5.3 software. Results A total of 28 articles were included in the study, of which 1 632 patients in the FTS group and 1 820 patients in the traditional group; 14 RCTs, 14 CCTs. The results of meta analysis showed: Compared with the traditional group, the FTS not only could reduce the pain of patients during 24 and 48 hours after the surgery [24 h: WMD=–0. 92, 95%CI (–1.05, –0.79), P<0.000 01; 48 h:WMD=–0.73, 95%CI (–0.90, –0.56), P<0.000 01], but also shorten the first postoperative flatus time of patients [WMD=–17.36, 95%CI (–23.16, –11.56), P<0.000 01] and the length of hospital stay [WMD=–2.42, 95%CI (–3.02, –1.63), P<0.000 01] and reduce the hos-pitalization expenses [WMD=–0.52, 95%CI (–0.64, –0.41, P<0.000 01]; While the incidences of pulmonary comp-lications [OR=0.51, 95%CI (0.32, 0.81), P=0.005], total complications [OR=0.57, 95%CI (0.38, 0.87), P=0.008], and nausea and vomiting [OR=0.45, 95%CI (0.31, 0.65), P<0.000 1] were significantly decreased. The RCT group and CCT group showed the same conclusions with the overall study (except incidence of postoperative pulmonary complications between the two groups in the CCT study). Conclusion For patients with elective hepatectomy, it seems feasible to use FTS protocol, which could promote postoperative bowel recovery, shorten length of hospital day, and save medical resources.
