Аннотация
BACKGROUND: Pancreatic surgery has developed over the last 60 years. A pancreaticoduodenectomy of the pancreatic head and duodenal papilla is the most common procedure. The most popular pancreatic cross-section site of a pancreaticoduodenectomy is the isthmus of the gland. The pancreatic isthmus anatomical configuration is still being considered.
STUDY DESIGN: The authors propose a new parametric descriptive system of pancreatic cross-section based on an elliptical model.
RESULTS: The pancreatic cross-section was evaluated as a geometric ellipse and the location of the pancreatic duct was based on coordinates. When analyzing the cross-section plane of the pancreatic isthmus, the mean size of the pancreatic isthmus cross-section was 10.46+/-2.34 mm in width (mean+/-SD) and 25.55+/-4.56 mm in length. The mean vertical/horizontal distance ratio was 0.42+/-0.12. The mean size of the main pancreatic duct was 1.02x2.46 mm. The mean distribution coordinates of the main pancreatic duct were: X 51.23; Y 50.60.
CONCLUSIONS: A proportional model of pancreatic isthmus cross-section analysis is easy and effective, and could become a valuable tool in future anatomical studies. The system described allows us to analyze data acquired from several investigators.
