Petersen’s hernia after living donor liver transplantation

Background Hepaticojejunostomy may be used for biliary reconstruction in certain cases of liver transplantation. In this occasion, Roux-en-Y biliary reconstruction is predominantly performed. Petersen’s hernia is an internal hernia that can occur after Roux-en-Y reconstruction, and it may lead to extensive ischemic changes affecting incarcerated portions of the small bowel or Roux limb resulting in severe complications with a poor prognosis.
