Interventions

  • Otheronline survey

    An online survey including 8 case-vignettes was sent to international liver transplant surgeons who had published on liver transplantation. The first part is related to surgeon's own experience. In the second part, the surgeons were asked to rate the difficulty of various situations in liver transplantation on a scale of 1 to 10 (level 1 was labeled as "easier," and level 10 was labeled as "difficult"). In the third part, 8 case-vignettes corresponding to 8 clinical real-life situations are submitted to experts
