Evidence is presented to show that maize starch particles, usually recognized in histological sections by their Maltese cross birefringence under cross-polarized light, lose this characteristic appearance when transected by the microtome blade. Such particles are, therefore, likely to be overlooked. Though maize starch usually enters the abdomen during surgery, the female genital tract is another possible route from sources such as contraceptive devices. Other types of starch particle have different shapes, sizes and surface markings and these may be distinguished from maize starch by light and electron optical methods.
有证据表明，玉米淀粉颗粒通常在组织切片中通过其在正交偏光下的马耳他十字双折射来识别，但当被切片机刀片切断时，会失去这种特征性外观。因此，这类颗粒很可能会被忽视。虽然玉米淀粉通常在手术过程中进入腹腔，但女性生殖道是来自避孕装置等来源的另一条可能途径。其他类型的淀粉颗粒具有不同的形状、大小和表面标记，这些可以通过光学和电子光学方法与玉米淀粉区分开来。
