Özet
Giris ve Amaç: Bu çalismadaki amacimiz terapötik- palyatif amaçli perkütan biliyer girisim uygulanmis hastalarda safra yollarindaki anatomik varyasyonlarin sikligini tespit etmekti. Gereç ve Yöntem: Mayis 2006 ile Nisan 2008 dönemi arasinda çesitli nedenlerle terapötik ve palyatif amaçli perkütan biliyer girisim uygulanmis 236 hasta gözden geçirildi. Hastalarin kolanjiyogramlari yazarlar tarafindan görüs birligi olusacak sekilde degerlendirildi. Intrahepatik safra yollarindaki varyasyonlar basli ca 7 tipe ayrildi ve her varyasyon tipinin sikligi hesaplandi. Bulgular: Çalisma kapsamindaki 236 hastanin 54 (yaklasik %23)?ünde anatomik varyasyon tespit edildi. En sik görülen anatomik varyasyon %8,5 ile trifurkasyondu. Bunu takiben en sik görülen diger iki varyasyon sag posterior segmental duktusun; sol hepatik duktusa (%5,9) ve ortak hepatik duktusa açilmasi (%5,5) idi. Sonuç: Hiler dallanma düzeyinde en sik görülen varyasyonlar trifurkasyon ve sag posterior segmental duktusun sol hepatik duktusa ve ortak hepatik duktusa açilimidir. Cerrahi ve biliyer girisim uygulanacak hastalarda anatomik varyasyonlarin bilinmesi önemlidir.
Abstract
Background and Aims: The aim of this study was to determine the anatomical variations of the biliary tree in patients undergoing percutaneous biliary intervention. Materials and Methods: Two hundred and thirty- six patients who underwent therapeutic and palliative percutaneous biliary intervention for various reasons between May 2006 and April 2008 were analyzed. Cholangiograms of the patients were evaluated by the authors and consensus was achieved. Anatomical variations of the biliary tree were classified into seven major types, and the frequency of each variation was calculated. Results: In 54 of the 236 patients (approximately 23%), anatomical variations were determined. The most frequently seen anatomical variation was trifurcation (8.5%), followed by the right posterior sectorial duct joining the left sectorial duct (5.9%) and the right posterior sectorial duct joining the common hepatic duct (5.5%). Conclusions: The most frequently seen variations in hilar bifurcation were trifurcation, right posterior sectorial duct joining left sectorial duct and right posterior sectorial duct joining common hepatic duct. Determining the anatomical variations in patients in whom surgery and biliary intervention are planned is important.
