PURPOSE: The aim of this study was to explore the feasibility of image classification of @entity96 surrounding right hepatic pedicle (RHP) and its guide to precise liver resection. METHODS: Twenty-five @entity1 with single @entity96 surrounding RHP were collected. According to the adjacent relationship between @entity5 and RHP shown in CT or MRI, the @entity96 were divided into the 4 types, @entity5 infiltrating or surrounding RHP, type B @entity5 locating in the anterior side of RHP, type C @entity5 locating in the dorsal side of RHP and type D @entity5 locating between the two branches. On the basis of image classification, operation project including hepatic @entity432 (HVO) and surgical resection procedure was designed. In the end, preoperative classification and surgical design was compared with operative results. RESULTS: The locations of @entity96 were completely in line with preoperative classification. The methods of HVO and range of surgical resection were essentially coincident with preoperative plan. Pringle maneuver, total hepatic and @entity432 were applied. Four @entity1 with type A @entity5 underwent right hemihepatectomy or extended right hepatectomy. Seven with type B received right anterior lobectomy or mesohepatectomy. Six with type C underwent segment V, VI resection, and eight with type D received right anterior or posterior lobectomy. All operations were smoothly finished. CONCLUSION: Preoperative classification guided by RHP can provide the accurate location information for @entity96 surrounding RHP, contribute to choosing suitable method of HVO and reasonable range of hepatic resection for precise surgery.
