腰肋三角解剖特点与急性胰腺炎并发左侧胸腔积液的关系

目的:探讨腰肋三角的解剖特点及其与急性胰腺炎并发左侧胸腔积液的关系。方法:对9具尸体标本进行解剖,分别测量左、右侧腰肋三角的面积及其与胰腺的垂直距离。结果:左侧腰肋三角的面积比右侧大,差异具有统计学意义(P<0.01);左侧腰肋三角与胰腺的垂直距离比右侧短,差异具有统计学意义(P<0.01)。结论:腰肋三角是急性胰腺炎并发胸腔积液的生要通路,左侧腰肋三角面积大且与胰腺距离近,是导致左侧胸腔积液多发的可能原因。

Relationship between the anatomic characteristics of lumbocostal triangle and left pleural effusion in acute pancreatitis

Objective To study the anatomic characteristics of lumbocostal triangle and the cause of left pleural effusion in acute pancreatitis. Methods The areas of left and right lumbocostal triangle and the vertical distance between the lumbocostal triangle and the pancreas were measured in nine cadavers. Results The area of left lumbocostal triangle was significantly larger than that of the right side, P〈0.01. The vertical distance between the left lumbocostal triangle and the pancreas was significantly shorter than that of the right side, P〈0.01. Conclusions Our results suggests that the lumbocostal triangle is an important pathway of pleural effusion in acute pancreatitis. Larger area and shorter distance with the pancreas of the left lumbocostal triangle may be the underlying cause of much more left pleural effusion in acute pancreatitis compared with right pleural effusion.
