In this issue of JAMA Surgery, DiNorcia et al1 suggest that damage control (DC) strategies adopted from the trauma experience can also be applied to hypothermic, coagulopathic, and/or hemodynamically unstable patients undergoing liver transplant. In this single-center, 10-year experience, 150 liver transplant recipients (8.3%) underwent intra-abdominal ...
