目的：探讨胆石性胰腺炎的产生与胆、胰合流部的解剖学关系。方法：对２９例新鲜成人尸体标本进行了实验及解剖学观察。结果：７９％（２３例）的胰管有防止胆胰返流的功能，其开口处和胆管之间菲薄的壶腹隔膜有“活瓣”样作用，可能是防止胆胰返流的重要结构。该活瓣构造不全者占１０％（３例）。胆管和胰管的汇合角度是造成壶腹隔膜构造变异的原因。结论：胆胰管汇合角度过大造成壶腹隔膜短而厚，“活瓣”功能丧失，使胆胰返流容易发生。这可能是共同通道过长者易发生胆石性胰腺炎的根本原因。
Objective: To investigate the anatomic relationship between gallstone pancreatitis and gallbladder pancreatitis. Methods: 29 fresh adult cadaver specimens were observed and anatomically observed. Results: The pancreatic duct of 79% (23 cases) had the function of preventing the reflux of bile and pancreas. The opening of the ampulla and the thin ampulla diaphragm between the bile duct had the function of “flap”, which may be the important structure to prevent the reflux of bile and pancreas . The valve defects accounted for 10% (3 cases). The confluence of the bile duct and the pancreatic duct is the cause of the structural variation of the ampulla of the diaphragm. Conclusion: The junction of bile duct and pancreatic duct is too large, causing the ampulla diaphragm to be short and thick. The function of “flap” is lost and the biliary and pancreatic reflux are easy to occur. This may be the common cause of overcrowding prone gallstone pancreatitis.
