Rouvière’s sulcus variants from a clinical perspective: A systematic review

Figure 1  PRISMA flow diagram.

Figure 2 An intra-operative image during single incision laparoscopic cholecystectomy that demonstrates an open-type Rouvière’s sulcus (arrows), whose medial end is continuous with the transverse fissure, posterior to the gallbladder. GB: Gallbladder; TF: Transverse fissure.

Figure 3 Intra-operative image during cholecystectomy, demonstrating a closed-type Rouvière’s sulcus, maintaining its posterior relationship to the gallbladder neck. The medial end of Rouvière’s sulcus is separated from the transverse fissure by a bridge of liver parenchyma (L) so that the sulcus is not continuous with the transverse fissure. GB: Gallbladder; TF: Transverse fissure.

Figure 4 Intra-operative image taken during laparoscopic cholecystectomy, demonstrating a slit-type Rouvière’s sulcus (arrow), posterior to the gallbladder. The sulcus is narrower than the operative instruments which are 5mm in diameter. GB: Gallbladder.

Figure 5 Intra-operative image taken at laparoscopic cholecystectomy, demonstrating a scar-type Rouvière’s sulcus (arrow). There is only a vague impression/white line seen at the expected location of Rouvière’s sulcus, maintaining its posterior relationship to the gallbladder. GB: Gallbladder.
