Abstract

Objective: Certain anatomical variations may represent preconditionsfor technical operation errors in right trisectionectomy. These varia-tions include: the confluence of the common bile duct, the length ofthe left hepatic duct, the localization of the bile duct confluence forsegments 2 and 3 of the umbilical portion of the left portal vein andthe peculiarities of the afferent and efferent blood supply of these twosegments. The aim of the present study is to identify and discuss suchpreconditions.Materials and Methods: The anatomical variations of the common bile duct confluence were analyzed by intraoperative cholangiography in 112 patients undergoing liver resections and in 32 preparations after left hepatectomy. The variations of the afferent and efferent blood supply were morphologically examined in 43 liver resections. Results: Seven types of anatomical variations of the common bile duct confluence were detected through intraoperative cholangiography, and three were extracted from the available literature. Three anatomical types (central, peripheral, and combined) of bile drainage from segment 4 were established. The mean distance between the bile duct confluence for segments 2 and 3 and the main hepatic duct confluence, i. e., the length of the left hepatic duct, was 3.68 cm. The anatomical peculiarities of the afferent and efferent arterial and venous supply of segments 2 and 3 were presented and discussed with respect to their roles in a safe right trisectionectomy. Conclusion: Surgeons’ sound knowledge of anatomical variations of the biliary tract and hepatic blood vessels coupled with increased experience and technique refinements could contribute to better outcomes in right trisectionectomy.

Özet

Amaç: Sağ triseksiyonektomide çeşitli anatomik varyasyonlar, cerrahi teknik hatalarına neden olabilir. Bu varyasyonlar ana safra kanalınınbirleşimini, sol hepatik kanalın uzunluğunu, 2. ve 3. segment safra yollarının konfluensinin lokalizasyonunu ve sol portal venin umbli- kal parçası ile yine bu iki segmentin afferent ve efferent kan akımının özelliklerini içermektedir. Bu çalışmanın amacı, bu varyasyonları ta- nımlamak ve tartışmaktır. Gereç ve Yöntem: Ana safra kanalı konfluensinin anatomik varyasyonları karaciğer rezeksiyonu uygulanan 112 hasta ve sol hepatektomi uygulanan 32 hastada intraoperatif kolanjiyografi ile analiz edildi. Afferent ve efferent kanlanmanın varyasyonları 43 karaciğer rezeksi- yonunda morfolojik olarak incelendi. Bulgular: Ana safra kanalı konfluensinin anatomik varyasyonlarının 7’si intraoperatif kolanjiografi ile, 3’ü ise mevcut literatürde varolan- lardan tespit edildi. Dördüncü segmentin safra drenajını sağlayan üç anatomik varyasyon (santral, periferik ve kombine) tespit edildi. Segment 2 ve 3 safra yolarının konfluensi ile ana hepatik kanal birleşimi arasındaki ortalama mesafe, yani sol hepatik kanalın uzunluğu; 3.68 cm olarak ölçüldü. Segment 2 ve 3’ün afferent ve efferent arteriyel ve venöz kanlanmalarının anatomik özellikleri sunulmuş ve güvenli bir sağ triseksiyonektomideki rolleri açısından tartışılmıştır. Sonuç: Safra yolları ve hepatik kan damarlarının anatomik varyasyonları konusunda cerrahların sağlam bir bilgi ve teknik iyileştirmeler ile artan deneyimi birleştiğinde doğru triseksiyonektomi için daha iyi sonuçlar elde edilmesine katkıda bulunabilir.
