Open Abdominal Management for Damage Control in Liver Transplantation: A Single-center Experience.

Abstract

Patients undergoing liver transplantation are in a state of coagulopathy before surgery because of liver failure. Intraoperative hemorrhage, massive transfusions, and post-reperfusion syndrome further contribute to coagulopathy, acidosis, and hypothermia. In such situations, temporary cessation of surgery with open abdominal management and resuscitation in the intensive care unit (ICU), which is commonly used as a damage control strategy in trauma care, may be effective. We assessed the outcomes of open abdominal management in liver transplantation and the corresponding complication rates. We retrospectively reviewed the outcomes of patients undergoing open abdominal management among 250 consecutive liver transplantation cases performed at our institution from 2009 to 2022. Open abdominal management was indicated in 16 patients. The open abdomen management group had higher Model for End-stage Liver Disease scores (24 versus 16, P < 0.01), a higher incidence of previous upper abdominal surgery (50% versus 18%, P < 0.01), more pretransplant ICU treatment (31% versus 10%, P = 0.03), and more renal replacement therapy (38% versus 12%, P = 0.01). At the time of the damage control decision, coagulopathy (81%), acidosis (38%), hypothermia (31%), and a high-dose noradrenaline requirement (75%) were observed. The abdominal wall was closed in the second operation in 75% of patients, in the third operation in 19%, and in the fourth operation in 6%. Postoperatively, the frequency of early allograft dysfunction was predominantly higher in the open abdominal management group (69%), whereas the frequency of vascular complications and intra-abdominal infection was the same as in other patients. Open abdominal management can be a crucial option in cases of complex liver transplant complicated by conditions such as hypothermia, acidosis, coagulopathy, and hemodynamic instability. Damage control management minimizes deterioration of the patient's condition during surgery, allowing completion of the planned procedure after stabilizing the patient's overall condition in the ICU.
