The aim of this study was to review the literature on the posterior gastric artery, estimate its prevalence and summarize its reported origins. The databases Pubmed, Scopus, Web of Science and Google Scholar were searched to find all studies describing the prevalence and origin of the posterior gastric artery. Pooled prevalences were estimated using a random effects model. Thirty-eight studies with a total of 3366 subjects were included in the analysis. The overall prevalence of the posterior gastric artery was 57.4% (95% CI = 49.1%-65.7%). The prevalence of the posterior gastric artery was significantly higher in surgical studies than in cadaveric and angiographic studies. There were no differences in prevalence between multi-detector computed tomography studies and cadaveric studies, nor were there differences when comparing geographical location or study size. Origin data were extracted from 34 studies, with a total of 1533 cases. The posterior gastric artery arose as a single vessel from the splenic artery in 1160 cases (pooled prevalence 86.5% [95% CI = 78.5%-94.7%]), from the superior polar splenic artery in 339 cases (pooled prevalence 11.8% [95% CI = 3.7%-19.9%]) and from other origins in 50 cases (pooled prevalence 0.27% [95% CI = 0.00-0.71%]). The posterior gastric artery is present in 57.4% of cases and most commonly arises from the splenic artery. It should be identified before gastric resections as it may be an important source of blood to the gastric stump. Multi-detector computed tomography has sufficient sensitivity to detect it before surgery.
本研究旨在回顾胃后动脉的文献，估计其发生率，并总结其报道的起源。通过检索 Pubmed、Scopus、Web of Science 和 Google Scholar 数据库，查找所有描述胃后动脉发生率和起源的研究。使用随机效应模型估计汇总发生率。共纳入 38 项研究，共计 3366 例患者。胃后动脉的总体发生率为 57.4%（95%CI=49.1%-65.7%）。手术研究中的发生率明显高于尸体和血管造影研究。多排 CT 研究与尸体研究的发生率无差异，地理位置或研究规模也无差异。从 34 项研究中提取起源数据，共 1533 例。胃后动脉起源于脾动脉单一血管的有 1160 例（汇总发生率 86.5%[95%CI=78.5%-94.7%]），起源于脾上极动脉的有 339 例（汇总发生率 11.8%[95%CI=3.7%-19.9%]），起源于其他部位的有 50 例（汇总发生率 0.27%[95%CI=0.00-0.71%]）。胃后动脉在 57.4%的病例中存在，最常见的起源于脾动脉。在进行胃切除术之前应识别它，因为它可能是胃残端的重要血液来源。多排 CT 术前具有足够的敏感性来检测它。
