The coeliac trunk (CoT) is an important branch of the abdominal aorta, that typically gives off the left gastric artery (LGA), the splenic artery (SA) and the common hepatic artery (CHA). Variations of the CoT are of great importance in clinical practice. The aim of the current systematic review with meta-analysis is to investigate the prevalence of these variants.
A systematic review was performed in four online databases to identify studies referring to CoT variants prevalence. A meta-analysis was conducted by using the R programming software to calculate the pooled prevalence of the variants, and to detect possible parameters affecting them by using subgroup analysis.
The typical anatomy was considered the CoT with three branches (type 3) with a pooled prevalence of 83.39 %. The most common variation was the CoT with two branches (type 2) identified in 10.53 %. Rarest types were considered the CoT with four branches (type 4-1.80 %) and the CoT absence (type 1-0.43 %). A statistically significant difference according to the type of study (imaging or cadaveric) was identified for CoT type 1 and type 4. Overall, the most common variation was the hepato-splenic trunk calculated with a pooled prevalence of 6.68 %.
The current systematic review with meta-analysis investigated the CoT variants and proposed a classification system based on the number of branches emanating from the trunk. Knowledge of these variations is of paramount importance for anatomists, radiologists and surgeons frequently operating the abdominal organs.
腹腔干（CoT）是腹主动脉的一个重要分支，通常发出胃左动脉（LGA）、脾动脉（SA）和肝总动脉（CHA）。腹腔干变异在临床实践中具有重要意义。本系统评价和荟萃分析的目的是调查这些变异的发生率。
在四个在线数据库中进行了系统评价，以确定提及腹腔干变异发生率的研究。使用R编程软件进行荟萃分析，计算变异的合并发生率，并通过亚组分析检测可能影响它们的参数。
典型解剖结构被认为是具有三个分支的腹腔干（3型），合并发生率为83.39%。最常见的变异是具有两个分支的腹腔干（2型），发生率为10.53%。最罕见的类型是具有四个分支的腹腔干（4型，发生率为1.80%）和无腹腔干（1型，发生率为0.43%）。对于1型和4型腹腔干，根据研究类型（影像学或尸体解剖）发现了统计学上的显著差异。总体而言，最常见的变异是肝脾干，合并发生率为6.68%。
本次系统评价和荟萃分析研究了腹腔干变异，并基于从主干发出的分支数量提出了一个分类系统。了解这些变异对于经常对腹部器官进行手术的解剖学家、放射科医生和外科医生至关重要。
