Background: Liver transplantation (LTx) is one of the most complex transplant procedures. The aim of the present study was to determine whether the learning process can be observed after the introduction of LTx in a center with extensive previous experience in renal transplantation.
Methods: This retrospective analysis included 264 primary LTx procedures performed with the piggyback technique (2005-2016). The procedures were divided into 4 equal groups. The characteristics of the recipients, data related to the surgery, and the postoperative course and complications were analyzed.
Results: We observed a significant reduction in surgical time and in the anhepatic phase duration between Group 1 and the other groups (median surgical time was 455 minutes vs 415 minutes, 410 minutes and 387 minutes, respectively, P < .05; median anhepatic phase duration was 75 min vs 60 min, 62 min, 60 min, respectively, P < .05). There was a decrease in the number of transfused blood units (median in Group 1 of 6 packs vs 3 packs in Group 4, P < .05) and a decrease in blood recovered from the operating field using the Cell Saver system (median in Group 1 of 1570 mL vs 1057 mL, 1123 mL, and 1045 mL, respectively, P < .05). A significant reduction in the number of hemorrhages was found (1.5% in Group 4 vs 13.6%, 10.6%, and 7.6% in the other groups P < .05). The remaining studied parameters were not statistically significant.
Conclusions: Extensive previous transplantation experience affected the lack of typical features of the learning process.
