    Abstract

    Donation after circulatory death (DCD) liver allografts are associated with higher rates of primary non-function (PNF) and ischemic cholangiopathy (IC). Advanced recovery techniques, including thoracoabdominal normothermic regional perfusion (TA-NRP), may improve organ utilization and patient and allograft outcomes. Given the increasing US experience with TA-NRP DCD recovery, we evaluated outcomes of DCD liver allografts transplanted after TA-NRP.Liver allografts transplanted from DCD donors after TA-NRP were identified from 5/1/2021 to 1/31/2022 across 8 centers. Donor data included demographics, functional warm ischemic time (fWIT), total warm ischemia time (tWIT) and total time on TA-NRP. Recipient data included demographics, model of end stage liver disease (MELD) score, etiology of liver disease, PNF, cold ischemic time (CIT), liver function tests, intensive care unit (ICU) and hospital length of stay (LOS), post-operative transplant related complications.The donors' median age was 32 years old and median BMI was 27.4. Median fWIT was 20.5 min; fWIT exceeded 30 min in two donors. Median time to initiation of TA-NRP was 4 min and median time on bypass was 66 min. The median recipient listed MELD and MELD at transplant were 22 and 21, respectively. Median allograft CIT was 292 min. The median length of follow up was 257 days. Median ICU and hospital LOS were 2 and 7 days, respectively. Three recipients required management of anastomotic biliary strictures. No patients demonstrated IC, PNF or required re-transplantation.Liver allografts from TA-NRP DCD donors demonstrated good early allograft and recipient outcomes.

    Abstract

    A 38-year-old man was brought in by ambulance as a trauma activation after sustaining a self-inflicted stab wound in the left upper quadrant with a kitchen knife. His primary survey was unremarkable and his vital signs were normal. Secondary survey revealed a 2 cm transverse stab wound inferior and medial to the left nipple. Extended focused assessment with sonography for trauma (FAST) did not show intra-abdominal or pericardial fluid and chest X-ray did not show a definite pneumothorax or hemothorax.Wound exploration at bedside.Admit for observation and serial examinations.Exploratory laparotomy and open repair of traumatic diaphragmatic injury (TDI).Thoracotomy and open repair of TDI.Diagnostic laparoscopy and laparoscopic repair of TDI.
