乙状结肠间隐窝的解剖学观测及其临床意义

The Clinical Significance and Anatomical Observation of Intersigmoid Recess

目的:对乙状结肠间隐窝进行解剖学研究,为影像学诊断及肛肠外科手术提供解剖学依据。方法:在92例盆腔标本上观察乙状结肠间隐窝的位置、形态及构成,测量其长度、宽度及毗邻结构间的距离,并对所得结果进行统计学分析。结果:乙状结肠间隐窝出现率为100%,形态为卵圆形、弧形、圆形和三角形;经统计学分析,两性之间无显著差异(P>0.05)。结论:乙状结肠间隐窝的形成、位置、毗邻均较恒定,对该区域的影像学检查及相关外科疾病的诊断和手术入路均有参考价值。

Objective： To study intersigmoid recess anatomically for providing an anatomical basis for imngeology diagnosis and surgery of anus and rectum. Methods： To observe the shape, location and formation of intersigmoid recess, and measure its length, width, and the distance between intersigmoid recess and its adjacent organs in 92 cases. The findings were analyzed with SPSS software. Results： Everyone has an intersigmoid recess. The shape of intersigmoid recess display orbicular, arcuated, round and triangle. The statistics analysis shows no conspicuous difference between male and famale. Conclusion： Intersigmoid recess plays an important role in imaging exam, diagnosis about related surgical diseases and operative approach, because its formation, position and adjacent organs are comparatively invariant.
