尾状沟是肝脏下表面的水平沟。此前尚未确定其患病率。由于其位置，它代表了一个有用的胆道外标志，可用于胆道手术以减少胆管损伤。本研究的目的是确定 Rouviere 沟的患病率并描述其解剖结构和相关的手术应用。我们对沟的各种特征进行了文献综述，选择了解剖临床研究和解剖。我们在普尔潘大学解剖学实验室进行了 10 具尸体解剖以确定其内容。我们选择了 1924 年至 2020 年 1 月 1 日期间进行的 12 项解剖学研究，其中包括 2394 名患者。沟的患病率为78.24%±9.1。辛格分类用于描述解剖特征。 50.4%±9.8 的病例被鉴定为 I 型（“深沟”），其中大部分为 Ia 型（开放型）。 II 型（“狭缝状”）估计占 13.3%±13.2，而 III 型（“疤痕”）则占 12.3%±8.0。平均尺寸估计为长度 (26 mm ± 5.7)、宽度 (6.5 mm ± 1.5) 和深度 (7.9 mm ± 1.75)。沟的内容由右门静脉及其分支、右肝动脉以及右肝胆管组成。沟决定胆总管的方向。尾状沟是可靠的胆外标志，为减少肝胆手术期间胆管损伤提供了有用的工具。
The sulcus of the caudate process is a horizontal groove on the inferior face of the liver. Its prevalence has not previously been determined. Because of its location, it represents a helpful extra-biliary landmark that could be used in biliary surgery to decrease bile duct injury. The goal of this study is to determine the prevalence of Rouviere’s sulcus and describe its anatomy and relevant surgical applications. We conducted a literature review on the various characteristics of the sulcus, selecting anatomical clinical studies and dissections. We performed 10 cadaveric dissections in the Laboratory of Anatomy at Purpan University to determine the contents. We selected 12 anatomical studies, conducted between 1924 and January 1st, 2020, which included 2394 patients. The prevalence of the sulcus is 78.24% ± 9.1. Classification of Singh was used to describe anatomical characteristics. Type I (“deep sulcus”) was identified in 50.4% ± 9.8 of cases, mostly consisting of Type Ia (open). Type II (“slit-like”) was estimated to account for 13.3% ± 13.2, whereas Type III (“scar”) described 12.3% ± 8.0. Average dimensions were estimated for length (26 mm ± 5.7), width (6.5 mm ± 1.5), and depth (7.9 mm ± 1.75). The content of the sulcus consists of the right portal vein and its division, the right hepatic artery, along with the right hepatic bile duct. The sulcus determines the orientation of the common bile duct. The sulcus of the caudate process is a reliable extra-biliary landmark, which presents a useful tool for reducing bile duct injuries during hepatobiliary surgery.
