Backgrounds/Aims: Hepatic artery (HA) reconstruction during living donor liver transplantation (LDLT) has been performed by experienced microsurgeons with operative microscope in most centers. However, it takes long time to learn the skills and so, to simplify this procedure, transplant surgeons recently performed this procedure using surgical loupe.
Methods: This study retrospectively reviewed outcomes of 237 LDLTs at our institution from January 2012 to October 2016. In group I, HA reconstruction was performed under operative microscope by an experienced microsurgeon and in group II, it was performed using surgical loupe by a transplant surgeon with little experience for arterial anastomosis.
Results: There was no difference in most perioperative outcomes between two groups except mean time required for HA reconstruction (24.2±4.3 vs. 20.9±6.9 minutes, p=0.001). Multivariable regression modeling to adjust for baseline differences showed that the use of surgical loupe was not associated with either HA thrombosis or intraoperative HA revision rate.
Conclusions: HA reconstruction under surgical loupe can be performed simply and yields results as good as with operative microscopy, even when the transplant surgeon has less experience with HA anastomosis.
