Abstract

Objective: To investigate the effect of bile duct variations on liver remnant volume in living donors,
according to the Huang classification.
Material and Methods: Triphasic abdominal Computed Tomography (CT) and magnetic
resonance cholangiopancreatography (MRCP) images of one hundred sixty-nine live donors were
analyzed retrospectively. Biliary tracts were divided into four categories according to the Huang
classification. Liver total and lobar volumes were calculated from CT images with a special computer
program (Myrian Pro; Intrasense, Montpellier, France). The volume was proportional to the left lobe
volume percentage. The categorical data of the Huang classification and the percentage of left lobe
volume were compared using the Kruskal-Wallis test. Values with P <0.05 were considered statistically
significant.
Results: According to Huang classification, there was no statistical difference in age and gender
distribution between categories (P = 0.756 and P = 0.124, respectively). There was no significant
relation between the groups in Huang classification and remnant left lobe volumes calculated through
the liver transplantation resection line (Cantlie line) (P = 0.354).
Conclusion: It was concluded that variations in biliary tract did not affect the remnant left lobe
volume in living liver donor candidates planned for right hepatectomy.

Sağ Hepatektomi Planlanan Canlı Karaciğer Donör Adaylarında Sol Lob Volümünün Huang Safra Yolu Varyasyonları ile İlişkisi

Abstract

Amaç: Huang sınıflandırmasına göre, safra kanalı varyasyonlarının canlı donörlerde karaciğer kalıntı
hacmi üzerine etkisini araştırmak.
Gereç ve Yöntemler: Yüz altmış dokuz canlı donöre ait, trifazik batın Bilgisayarlı Tomografi (BT)
ve manyetik rezonans kolanjiopankreatografi (MRKP) görüntüleri retrospektif olarak incelendi.
MRKP ile safra yolları huang sınıflamasına göre dört kategoriye ayrıldı. BT görüntülerinden özel
bir bilgisayar programıyla (Myrian Pro; Intrasense, Montpellier, France) karaciğer total ve lobar
volümleri hesaplandı. Sol lob volümü total volume oranlanarak sol lob volüm yüzdesi bulundu.
Huang sınıflaması kategorisel verileri ile sol lob volüm yüzdesi verileri Kruskal-Wallis testi aracılığıyla
karşılaştırıldı. İstatistiksel olarak P<0.05 olan değerler anlamlı kabul edildi.
Bulgular: Huang sınıflamasına göre kategoriler arasında yaş ve cinsiyet dağılımında istatistiksel fark
izlenmedi (sırasıyla; p= 0,756 ve p= 0,124). Karaciğer transplantasyon rezeksiyon hattına (Cantlie
hattı) göre hesaplanan remnant sol lob volümleri ile Huang sınıflamasındaki gruplar arasında anlamlı
ilişki saptanmadı (p= 0,354).
Sonuç: Sağ hepatoktomi planlanan canlı karaciğer vericilerinde safra yollarındaki varyasyonların
remnant sol lob volümünü etkilemediği sonucuna varıldı.
