Laparoscopic-Assisted Transgastric Endoscopic Retrograde Cholangiopancreatography With Placement of a Biliary Stent to Treat Traumatic Intrahepatic Bile Duct Disruption in a Patient With Roux-en-Y Gastric Bypass.

Hepatic injuries are common following blunt trauma and while frequently managed expectantly, biliary injury as a result of the trauma requires a high index of suspicion, a focused workup, and likely interventional treatment. A 44-year-old female with a history of Roux-en-Y gastric bypass presented after a ground level fall and was initially discharged home but represented with worsening abdominal pain and elevated liver enzymes. She was found to have a segment 5/6 biliary injury requiring laparoscopic-assisted transgastric endoscopic retrograde cholangiopancreatography with common bile duct stent placement. This case represents the difficulty of diagnosing biliary injuries following blunt trauma, and the need for advanced endoscopic interventions for treatment in patients with atypical anatomy.
