VITERI-CEVALLOS, Diego Fernando. Usefulness of magnetic resonance cholangiopancreatography (MRCP) in patients with bile duct injury. Cir. gen [online]. 2017, vol.39, n.1, pp.19-25.  Epub 26-Mar-2020. ISSN 1405-0099.


Benign biliary strictures include several clinical entities; the most important group is for those who had a postoperative bile duct injury (BDI), the incidence of which has risen from 0.1-0.2% to 0.4-0.7% from laparoscopic cholecystectomy, although the incidence is similar to that of open surgery in the hands of expert surgeons. Within the diagnostic, MRCP has proven to be comparable with ERCP in the location and extent of extrahepatic LVB, with a sensitivity of 91 to 100%.

Material and methods:

A retrospective correlation was performed in the Gastrosurgery Service of HE Siglo XXI. The correlation (Cohen’s kappa) between the MRCP with surgical findings in patients undergoing LVB was observed, as well as its validation as a diagnostic tool.


Forty patients were included in this study. It was found that the overall correlation for the presence of BDI was 0.55; the one identified in relation to the anatomical level of the LVB was 0.59; to determine whether the BDI was complete or partial, kappa was of 0.39, and for the presence of intraabdominal collections, 0.59 (0.32 to 0.86). Regarding the diagnostic accuracy, it was found that to determine globally the presence of a BDI, the sensitivity (S) was 88.9% and the specificity (Sp) of 80%; to determine the level of preoperative lesion, S was 84% and Sp 26%.


We conclude that there is a moderate correlation between MRCP diagnostic and surgical findings in patients undergoing surgery for bile duct injury.
