Frequency and Morphological Pattern of Rouvier's Sulcus in Human Liver

Abstract

Background and Objective: Rouvier's Sulcus is present as an indentation on the inferior aspect of right lobe
of liver. It is used as an anatomical landmark by surgeons to begin dissection during laparoscopic
cholecystectomy. It may be oriented horizontally, obliquely or vertically. The aim of our study was to
determine the morphological appearance, size, frequency, types and orientation of Rouvier's Sulcus.
Methods: A cross-sectional study was conducted on 38 formalin fixed cadaveric livers from March 2024 to
August 2024. The livers which were healthy on gross examination were taken and measurement of rouvier's
sulcus was done along with its type and orientation.
Results: Rouvier's sulcus was present in 68% of the sample (mean length: 2.91cm). Three types were
observed: Type 1A (46%), Type 1B (23%), and Type 2 (26.9%). Type 3 was rare (3.8%). Sulcus orientation
was mainly oblique (80.7%) or horizontal (19.2%).
Conclusion: The rouvier's sulcus is a consistent, easily identifiable landmark unaffected by biliary
inflammation or cirrhosis. Its most common morphology noted is Type I, facilitates clear visualization of
biliary and vascular structures.
Key Words: Laparoscopic cholecystectomy, anatomical landmark, liver, rouvier's sulcus.
