    Comparison of Intraoperative Biliary Anastomosis Stenting Technique in Living-Donor Liver Transplantation: Review of 41 Patients
    (Turkiye Klinikleri, 2022) Dönmez, Ramazan; Balas, Ş.; Göktuğ, U.U.; Emek, E.; Tokat, Y.; Tıbbi Hizmetler ve Teknikler Bölümü
    Background/aim: Biliary fistula is one of the most important complications in liver transplantation. Complications can vary from simple local peritonitis to death, and various techniques have been described to prevent them. In this study, we compared two different stenting methods used in biliary tract anastomosis in living-donor liver transplantation. Material and methods: We retrospectively analyzed data from 41 living-donor liver transplantations that were performed due to end-stage liver failure between August 2019 and November 2020. Patients were grouped according to the stenting technique used in biliary anastomosis. Postoperative biliary tract complications were investigated. Results: Biliary fistulas were observed in 2 (7.4%) patients in the internal stent group, while 4 (28.5) fistulas were observed in the external stent group. Biliary tract stricture was observed in 2 (7.4%) patients in the internal stent group, but there was no statistical difference in complications. The preoperative MELD score (p = 0.038*) was found to be statistically significant in regard to developing complications. Conclusion: Our study did not show the effect of stenting methods used during biliary anastomosis on the development of complications. However, larger randomized controlled studies are needed. © TÜBİTAK.

    Evaluation of the Compatibility of Preoperative Mrcp and Intraoperative Cholangiography in Imaging of the Bile Ducts in Living Donor Liver Transplantation
    (Springer india, 2022) Dönmez, Ramazan; Gormez, Aysegul; Tıbbi Hizmetler ve Teknikler Bölümü
    To evaluate the compatibility of preoperative 3D magnetic resonance cholangiopancreatography (3D MRCP) and intraoperative cholangiographies (IOC) of donors using Huang classification in living donor liver transplantation. Thirty-six consecutive right donor hepatectomy cases were retrospectively analyzed with preoperative MRCP and intraoperative cholangiography. Biliary variants were determined according to the Huang classification. Compatibility in MRCP and IOC was evaluated. 3D MRCP accurately determined the biliary anatomy in 32 of 36 cases (88.88%). The IOC of the 36 donors showed 25 normal bifurcations and 11 biliary variants. For detecting normal and variant anatomy, sensitivity, specificity, PPV, and NPV were 96.0%, 72.7%, 88.9%, and 88.9.0%, respectively. There was a substantial inter-rater agreement between IOC and MRCP in determining normal and variant anatomy (kappa = 0.724, p < 0.001). 3D MRCP is a non-invasive useful method to evaluate non-dilated bile ducts preoperatively in living donor liver transplantation. The eligibility criteria determined according to preoperative MRCP images should also be confirmed by intraoperative cholangiography.
