Methods and materials

This is a retrospective cross-sectional study with 44 patients who underwent ultrasonography (US), computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) with and without hepatospecific contrast agent, endoscopic retrograde cholangiopancreatography (ERCP) and/or percutaneous transhepatic cholangiography (PTHC) as well as fistulography due to complications following iatrogenic bile duct damage due to laparoscopic cholecystectomy.

All types of biliary tract injuries were evaluated by the certified radiologist, and IBI were classified according to Strasberg et al. classification, and results were compared with the surgical Strasberg et al. classification. Strasberg et al. classification of bile duct injuries see img 1.

IBM SPSS software, version 22.0 (IBM Corm., Armonk, N.Y., USA) and MS Excel 2010 software were used for statistical analysis and graphing.
