Abstract
Ischemia time is a well-established determinant of liver transplant outcomes. Patient survival is substantially affected by prolonged warm (WIT) and cold ischemia time (CIT) of the graft during liver transplant. One component that may be a contributing factor to both WIT and CIT is back bench time (BBT). We have identified BBT as a potentially significant underlying cause of post transplant complications.
A literature search was performed using the major available databases. Articles comparing grafts using normothermic machine perfusion and static cold storage with measured WIT and CIT, and post-transplant outcomes, were included. A total of 18 studies were selected; however, we were only able to identify two studies that refer to BBT. In this systematic review, we conclude BBT is a modifiable factor of ischemia that may be impacted by the surgeon experience and requires more in depth studies to fully understand a safe threshold and its effect on post transplant outcomes such as EAD, IC, and graft survival.
期刊介绍：
Chirurgia is a bimonthly journal. In Chirurgia, original papers in the area of general surgery which neither
appeared, nor were sent for publication in other periodicals, can be published. You can send original articles,
new surgical techniques, or comprehensive general reports on surgical topics, clinical case presentations and,
depending on publication space, - reviews of some articles of general interest to surgeons from other publications.
Chirurgia is also a place for sharing information about the activity of various branches of the Romanian Society of
Surgery, information on Congresses and Symposiums organized by the Romanian Society of Surgery and
participation notes in other scientific meetings.
Letters to the editor: Letters commenting on papers published in Chirurgia are welcomed. They should contain
substantive ideas and commentaries supported by appropriate data, and should not exceed 2 pages. Please
submit these letters to the editor through our online system.
