The normal pattern of the celiac trunk (CT) implies its bifurcation to three branches, the common hepatic, the splenic and the left gastric artery. According to the available literature the CT presents several anatomical variations. The purpose of our study is to investigate the different types of these variations, the corresponding incidences and the probable influence of genetic factors, as they are presented in the existing literature. Four databases were searched for eligible articles for the period up to January 2013 and a total of 36 studies were collected. The CT was trifurcated into the three basic branches in the 89.42% (10,906/12,196) of the cases. Bifurcation of the CT occurred in the 7.40% of the pooled samples (903/12,196). Absence of the CT was the rarest variation with a percentage of 0.38% (46/12,196), hepatosplenomesenteric trunk was found in 49 out of the 12,196 cases (0.40%) and the celiacomesenteric trunk presented an incidence of 0.76% (93/12,196). Other variations of the CT were detected in the 1.64% of the pooled cases (199/12,196). The 14.9% of the cases in the cadaveric series (489/3278 specimens), the 10.5% in the imaging series (675/6501 specimens) and the 4.6% (104/2261) in the liver transplantation series presented variations. These differences are statistically significant (p<0.001). The Japanese and Korean populations presented more variations in the CT than Caucasians (p<0.05 and p<0.001). Negro, colored and black populations presented more variations of the CT than Indian ones (p>0.05). Using those data, a novel classification of CT variations is proposed.
腹腔干（CT）的正常模式意味着它分为三个分支，即肝总动脉、脾动脉和胃左动脉。根据现有文献，CT 存在几种解剖变异。我们研究的目的是调查这些变异的不同类型、相应的发生率以及遗传因素的可能影响，因为它们在现有文献中有所体现。我们在四个数据库中搜索了截至 2013 年 1 月的符合条件的文章，并收集了总共 36 项研究。在 12196 例患者中，89.42%（10906/12196）的 CT 分为三个基本分支。CT 分叉发生在总样本的 7.40%（903/12196）中。CT 缺失是最罕见的变异，占 0.38%（46/12196），肝脾肠系膜干在 12196 例中有 49 例（0.40%），腹腔肠系膜干的发生率为 0.76%（93/12196）。在总样本的 1.64%（199/12196）中发现了 CT 的其他变异。在尸体系列中，14.9%（489/3278 例标本）、影像学系列中，10.5%（675/6501 例标本）和肝移植系列中，4.6%（104/2261 例标本）存在变异。这些差异具有统计学意义（p<0.001）。与高加索人相比，日本人、韩国人和中国人的 CT 变异更多（p<0.05 和 p<0.001）。与印度人相比，黑人、有色人和黑人的 CT 变异更多（p>0.05）。利用这些数据，我们提出了一种新的 CT 变异分类方法。
