Amaç: Karaciğer donöründe hepatosteatoz (HS) varlığı, karaciğer transplantasyonu sonuçları üzerinde olumsuz etkilere sahiptir. Bu nedenle, donörde HS’nin tespiti, nakil öncesi dönemde hayati önem taşımaktadır. Bu çalışmanın amacı, canlı karaciğer donör adaylarında HS’nin saptanmasında karaciğer biyopsisi ve radyolojik yöntemlerin etkinliğini karşılaştırmaktır. Gereç ve Yöntem: Demiroğlu Bilim Üniversitesi’ne karaciğer transplantasyonu için donör adayı olarak kabul edilen 226 sağlıklı birey çalışmaya dahil edildi. Donörlerin demografik, histopatolojik, laboratuvar ve görüntüleme bulguları retrospektif olarak incelendi. Donörlerin bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) taramaları geriye dönük olarak yeniden değerlendirildi ve karaciğer yağ ölçümleri kaydedildi. Bulgular: Hastaların %39’u (88) kadın, %61’i (138) erkekti. Çalışma popülasyonunda ortalama yaş 34,3±8,7 yıl, ortalama ağırlık 78,0±12,6 kg, ortalama boy 169,1±9,6 cm ve ortalama vücut kitle indeksi 27,2±4,0 idi. Karaciğer biyopsisinde donörlerin %42’sinde <%5 HS vardı ve donörlerin %58’inde >%5 HS vardı. Hem BT hem de MRG, HS saptamada biyopsi ile anlamlı korelasyon gösterdi (p<0,05). Sonuç: Çalışmamızda MRG’nin BT kadar biyopsi ile ilişkili olduğu ve HS’nin saptanmasında rahatlıkla kullanılabileceği bulunmuştur. Karaciğer donörlerinde MRG kullanımı, iyonizan radyasyon içermemesinden dolayı nakil öncesi donör için daha uygun bir yöntem olabilir.

Effects of Peroperative Cold Ischemia Time and Anhepatic Phase in Adult Living Donor Liver Transplant Recipients: Operation Time That Is Not Affected by the Anhepatic Phase but Is Prolonged by Cold Ischemia Time

Objective. It was aimed to examine the overall role of cold ischemia time and anhepatic phase durations in terms of peroperative blood transfusion needs, hospital stay conditions and postoperative charges, and survival in recipients. Material and Methods. One hundred forty-eight adult living donor liver transplant recipients (18 years and older) were included in the study. Whether the anhepatic phase and cold ischemia duration have an effect on the rates of surgery time, blood product transfusion, total hospital and intensive care unit stay, postoperative biliary complications, hepatic vein thrombosis, portal vein thrombosis, early postoperative bleeding, sepsis, and primary graft dysfunction. Was analyzed statistically. In addition, the effect of the anhepatic phase and cold ischemia time on graft survival was statistically examined by creating an average of the patient follow-up period. Results. It was observed that the operation time increased statistically as the cold ischemia time increased (P P = .000). No statistically significant fi cant relationship was found between other fi nd- ings and cold ischemia time and anhepatic phase. Conclusion. Prolonged surgery time due to increased cold ischemia time may be an important fi nding in terms of peroperative and postoperative results of the graft.

A Single-center's Early Surgical Outcomes of Living Donor Liver Transplantation
(Elsevier Science inc, 2023) Oral, Alihan; Oral, Alihan; Atasoy, Alp; Civan, Hasret Ayyildiz; Topcu, Feyza Sonmez; Bayramoglu, Mert; Unal, Bulent; Tıbbi Hizmetler ve Teknikler Bölümü
Background. Living donor liver transplantation (LDLT) has become an increasingly common surgical option because the number of cadaveric donors is insufficient to fulfill the organ needs of patients facing end-stage cirrhosis. Many centers are investigating different surgical techniques to achieve lower complication rates. We aimed to examine our complication rates in light of demographic data, graft data, and perioperative findings as a single-center experience. Methods. The study included one hundred and three patients who underwent LDLT for endvein, and bile anastomosis type rates; anhepatic phase; cold ischemia time; operation time; and blood product transfusion rates were analyzed. Biliary complications in patients with single or multiple biliary anastomoses, right or left liver transplants, and with or without hepatic artery thrombosis were analyzed statistically. Results. There was no significant difference in biliary complications between patients who underwent single or multiple bile anastomosis (P = .231) or patients receiving right lobe and left lobe transplants (P = .315). Although there was no statistically significant difference in the rate of portal vein thrombosis between the regular and reconstructed portal vein anastomosis groups (P = .693), the postoperative portal vein thrombosis rate was statistically higher in patients with left lobe transplants (P = .044). Conclusions. Vascular and biliary complication rates can be reduced with increasing experience.
