Isolated right posterior bile duct injury following cholecystectomy: Report of two cases

Figure 1 Dangerous anatomical variants of right posterior hepatic duct draining into the cystic duct (A), gall bladder neck (B) or the common hepatic duct (C). RPHD: Right posterior hepatic duct.

Figure 2 Endoscopic retrograde cholangiogram showing seemingly “normal” biliary tree with no evidence of a biliary leak. However, only the left hepatic duct (long arrow) and the right anterior hepatic duct (short arrow) are visible.

Figure 3 Magnetic resonance cholangiography with the use of T2-weighted sequences and maximum-intensity-projection imaging. The fluid-containing bile ducts as high signal-intensity structures; the right posterior hepatic ducts of segments 6 and 7 are shown (double arrow) with no connection to the right anterior duct (single short arrow) and the left hepatic duct (single long arrow); the abdominal drain placed in the subhepatic area and draining the bile externally is also visible in between the right anterior and posterior hepatic ducts.
