摘要：

目的探讨胃裸区和胃周围间隙的划分、形态学特征及其在影像学的应用意义。方法将 65具成人尸体解剖观测胃裸区后膈下腹膜外间隙；46具成人尸体腹部连续断层标本,观测胃裸区后膈下腹膜外间隙出现平面、范围。选2例上腹部标本在胰尾处向肾旁前间隙内灌注红色乳胶，观察乳胶胰在周围的扩散和积聚情况。结果尸体解剖观测发现胃裸区位于食管腹段后方、邻近胃小弯侧胃的后壁无腹膜覆盖的区域，其出现率为100%。胃膈内侧韧带、胃膈外侧韧带和胃胰韧带勾画出胃裸区的范围，胃裸区与左膈之间的间隙为左侧膈下腹膜外间隙。胃周围间隙可划分为肝胃隐窝、网膜囊上隐窝、左侧膈下腹膜外间隙、网膜囊下隐窝、脾胃隐窝。左侧膈下腹膜外间隙与左肾旁前间隙相交通。结论（1）胃膈内侧韧带、胃膈外侧韧带和胃胰韧带勾画出胃裸区的范围,它们是划分胃周围间隙依据。（2）胃周围间隙可划分肝胃隐窝、网膜囊上隐窝、左侧膈下腹膜外间隙、网膜囊下隐窝、脾胃隐窝。（3）左侧膈下腹膜外间隙与左肾旁前间隙相通。

Abstract:

Objective To investigate anatomic features of perigastric space and gastric bare area, and explore their clinical values. Methods Perigastric space and gastric bare area were dissected and analyzed on 65 adult cadavers, while continuous cross sections of 46 cadaveric abdomens were performed and observed the appearance plane and scope of extraperitoneal space in posterior gastric bare area under diaphragm. 2 specimens of epigastrium were perfused red latex into pararenal space from the site of the tail of pancreas and observed the distribution of it. Results For all specimens, gastric bare area was behind abdominal esophagus, near the posterior wall of stomach, without peritoneal covering. Gastric bare area was divided by internal gastrophrenic ligament, external gastrophrenic ligament and gastropancrestic ligament. Left extraperitoneal space under diaphragm was the space between gastric bare area and left diaphragm. Perigastric space could be divided into hepatogastric recess, superior recess of lesser sac, left extraperitoneal space under diaphragm, inferior recess of lesser sac, and gastrosplenic recess. Left extraperitoneal space under diaphragm had connection with left anterior pararenal space. Conclusions （1） Gastric bare area is divided by internal gastrophrenic, external gastrophrenic and gastropancrestic ligaments, which are marks for the division of perigastric space area. （2）Perigastric space can be divided into hepatogastric recess, superior recess of lesser sac, left extraperitoneal space under diaphragm, inferior recess of lesser sac, and gastrosplenic recess.（3）Left extraperitoneal space under diaphragm connects with left anterior pararenal space.
