Sham feeding has been reported to enhance bowel motility. Here, to promote gastrointestinal function after postoperative ileus, the effect of gum chewing (GC) was evaluated.
Literature search including PubMed, Embase, Science Citation Index, SpringerLink, and secondary sources. Fixed-effect and random-effects models were used to measure the pooled estimates. The test of heterogeneity was performed with the Q statistic. Stratified and sensitivity analyses were performed to explore heterogeneity between studies and to assess effects of study quality.
GC was well tolerated in a total of 1,148 cases in this meta-analysis. The pooled weighted mean difference for time to first flatus and bowel movement in GC was found to be -9.21 (95% CI: -12.07 to -6.34; p < 0.01) and -11.42 (95% CI: -16.05 to -6.79; p < 0.01), respectively, compared to standardized postoperative care. The intervention also decreased length of hospitalization by 12.23 h (95% CI: -18.80 to -5.67; p = 0.0003). Subgroup analyses for different abdominal procedures all favored GC.
This meta-analysis demonstrated that GC was safe and easily tolerated without any complications following abdominal surgery to potentially shorten postoperative ileus.
假饲已被报道能增强肠道蠕动。在这里，为了促进术后肠梗阻后的胃肠功能，评估了咀嚼口香糖（GC）的效果。
文献检索包括 PubMed、Embase、科学引文索引、施普林格链接和二级来源。使用固定效应和随机效应模型来测量汇总估计值。用 Q 统计量进行异质性检验。进行分层和敏感性分析，以探索研究之间的异质性，并评估研究质量的影响。
在这项荟萃分析中，GC 在总共 1148 例患者中得到了很好的耐受。与标准化术后护理相比，GC 组首次排气和排便的时间的汇总加权均数差分别为-9.21（95%CI：-12.07 至-6.34；p < 0.01）和-11.42（95%CI：-16.05 至-6.79；p < 0.01）。干预还使住院时间缩短了 12.23 小时（95%CI：-18.80 至-5.67；p = 0.0003）。不同腹部手术的亚组分析均有利于 GC。
这项荟萃分析表明，GC 在腹部手术后是安全且易于耐受的，没有任何并发症，可能缩短术后肠梗阻的时间。
