Background and Aim Accurate anatomical delineation is the key before definitive repair for benign biliary stricture (BBS). The role of percutaneous transhepatic cholangiography (PTC) as a road map is less studied in the era of magnetic resonance cholangiopancreatography (MRCP). Methods A prospective observational study, performed between July 2012 and December 2013. All patients of post‐cholecystectomy BBS were evaluated with MRCP and PTC prior to definitive repair. Findings of MRCP and PTC were compared with intraoperative details. Results Thirty patients with BBS were included in the study. MRCP was performed in all but PTC was amenable in 28 of 30 (93.3%) patients. PTC was comparable to MRCP in diagnosing stricture type (96.4% vs 89.3%), intrahepatic stones (75% vs 75%), and biliary anomalies (95.6% vs 100%). Additionally, PTC revealed internal biliary fistula in 4 (85.7% vs 61.4%; P value 0.04). PTC‐related minor complications were noted in 2 (7.1%) patients. Conclusion PTC is comparable to MRCP in diagnosing the stricture type, intrahepatic biliary stones, and biliary anomalies. Though comparable to MRCP, the authors could not reveal any additional information that could change the course of management in BBS.
