To determine the incidence of AS after right lobe living donor liver transplantation with various biliary reconstructions and to identify the predictors of this complication. A retrospective and prospective analysis included 245 RLLDLTs for the period 2011-2018 at the Burnazjan Federal Medical Biophysical Center. The results of transplantations in 207 patients aged 19-68 years (median 43 years) were assessed. There were 82 men and 125 women. Follow-up period ranged from 10 to 98 months (median 35 months). We analyzed the relationship between surgical characteristics (preoperative data of recipients and donors, graft parameters, technical features of biliary reconstruction and features of post-transplantation period) and incidence of anastomotic strictures. A total of 58 parameters were analyzed. AS occurred in 20 (9.7%) recipients. Median AS-free period was 5 months (range 1-44). In 17 (85%) patients, AC developed within a year after surgery. Cumulative 1-, 2- and 5-year incidence of AS was 8.3%, 8.9%, and 11%, respectively. Significant predictors of AS were impaired arterial blood supply to the graft (HR 7.8, 95% CI 2.3-26.0, p<0.001), biliary leakage ISGLS class B or C (HR 5.0, 95% CI 2.0-12.8, p<0.001), early allograft dysfunction (HR 4.2, 95% CI 1.5-11.6, p=0.006) and female recipient (HR 3.2, 95% CI 1.1-9.9, p=0.04). In our sample, variant biliary anatomy of the graft and recipient liver, as well as technical features of biliary reconstruction did not affect the risk of AS. Variant biliary anatomy of potential donor alone should not be considered as a contraindication for organ donation and right liver lobe transplantation. Precise surgical technique, high transplantation activity, as well as experience of reconstructive interventions on the bile ducts during other operations can significantly reduce the incidence of AS after RLLDLT up to 9.7%.
