Official title
Anatomical Variation in Rouvière's Sulcus: a Cross-sectional Study
Overview
Rouvière's sulcus is a 2-5 cm fissure lying on the lower face of the liver, between the right lobe and caudate process. Due to its extrabiliary location, Rouvière's Sulcus could be used as an anatomical landmark for safe laparoscopic cholecystectomy. In literature there's an high variability about Rouvière Sulcus prevalence and its anatomical variants.
Detailed description
The goal of this observational study is to evaluate the presence of Rouvière Sulcus in patients underwent laparoscopic cholecystectomy. The main questions it aims to answer are the prevalence and the anatomical variations of Rouvière's Sulcus and the variants of Rouvière's Sulcus which are catheghorized according to Singh and Prasad criteria.
The following were considered secondary outcome: operative time expressed in minutes, biliary tract injuries according to Stewart's classification and Vascular injuries.
