胃肠道穿孔（食管下段到结肠）能导致腹膜炎，如图尸检所见。浓密的黄*色脓性渗出物覆盖在腹膜表面。卵巢癌引起乙状结肠的梗阻、穿孔。骨盆中可见明显扩张和灰黑色的乙状结肠。
Perforation of GI tract (from lower esophagus to colon) can result in a peritonitis as seen here at autopsy. A thick yellow purulent exudate covers peritoneal surfaces. An ovarian carcinoma caused sigmoid colonic obstruction (the sigmoid is the markedly dilated grey-black bowel in the pelvis seen here) with perforation.
