Abstract
Background: Rouviere’s sulcus (RS) was first identified in 1924 by Henri Rouviere. It lies oblique to the anterior and inferior border of the liver and holds the right portal pedicle. Material and Methods: The study was conducted in the Department of Anatomy of a Medical College in Maharashtra, India, on 45 cadaveric livers. The morphological observations made were: presence/ absence RS; direction of RS (oblique/ horizontal/ vertical); sulcus type ( deep/ slit/ scar); length, width and depth; presence of right hepatic pedicle; distance of the hepatic vessels from edge of the sulcus . Results: 40 livers showed the presence of Rouviere’s Sulcus. It was absent in five specimens. Direction was horizontal in 40%, oblique in 57.5% and vertical in 2.5% .26 livers showed a deep type of sulcus, 12 showed the slit type and 2 showed scar type .29 livers showed the right hepatic pedicle entering the RS. Average length, depth, of the RS was 2.35 cm and1.07 cm respectively. The average width was 0.32cm at medial end, 0.22cm at midpoint and 0.1cm at lateral end. Present study has added the details of depth of vessels from the edge of RS, which was not recorded in earlier studies. Depth of vessels from the edge of the sulcus was average 5mm (0.5cm) for the right branch of the hepatic artery and was 12mm (1.2cm) for the right branch of portal vein. Conclusion: Rouviere’s sulcus is a reference landmark for surgeons during laparoscopic surgeries on gall bladder and during hepatic resection to avoid injuries. This study wishes to provide detailed morphological data of the Rouviere’s Sulcus to hepatobiliary surgeons including depth of hepatic vessels in the RS as an added parameter to aid them in their surgical endeavor. KEY WORDS: Rouviere’s sulcus, Anatomical Landmark, Morphology, Depth, Hepatobiliary Surgery.
