BHANA, M; BERNON, M; KLOPPERS, JC  and  JONAS, E. Misinterpretation of the severity of bile duct injuries by MRCP. S. Afr. j. surg. [online]. 2024, vol.62, n.2, pp.190-193. ISSN 2078-5151.  https://doi.org/10.36303/SAJS.00411.

BACKGROUND: Magnetic resonance imaging (MRI) is widely regarded as the gold standard for assessment of the bile ducts in patients with bile duct injuries (BDIs). This case series aims to highlight the shortcomings of this imaging modality and demonstrate how it may overestimate the injury severity. METHODS: Three patients treated at Groote Schuur Hospital and the University of Cape Town in whom MRI/magnetic resonance cholangiopancreatography (MRCP) overestimated the severity of BDI were included in the study. Demographic characteristics, clinical presentation, blood results and imaging findings are presented. RESULTS: All patients had an MRI/MRCP done which assessed the BDIs as major complete cut-off of the proximal common hepatic duct with substance loss. Subsequent direct cholangiography showed minor injuries and all three patients were successfully managed with endoscopic stenting. CONCLUSION: Major BDIs are complex, and assessment of severity is intricate and may be overestimated. These patients are best managed in high-volume multidisciplinary team settings.

Keywords : bile duct injury; magnetic resonance imaging; endoscopic retrograde cholangiography.
