Incidental findings of thickened luminal GI organs (LGIO) on CT are not uncommon. However, the significance of these findings is unclear. Because of the lack of scientific data, there are no clinical guidelines for the evaluation of these radiologic abnormalities. Our objective was to determine whether endoscopic evaluation of these findings revealed significant abnormalities.
This study evaluated all incidental findings of thickened LGIO in a large medical center from October, 1997 to March, 1999 that were followed by endoscopic examinations.
Ninety-six percent of patients with incidental findings of thickening of the sigmoid colon or rectum, 81% of patients with thickening of the distal esophagus, and 13% of patients with thickening of the cecum had significant abnormalities on further endoscopic work up.
Although positive pathologic findings are less common in thickening of the cecum than in other LGIO, all of these incidental findings on CT warrant further endoscopic examination.
CT检查偶然发现的管腔胃肠道器官（LGIO）增厚并不少见。然而，这些发现的意义尚不清楚。由于缺乏科学数据，目前尚无针对这些放射学异常评估的临床指南。我们的目的是确定对这些发现进行内镜评估是否会发现显著异常。
本研究评估了1997年10月至1999年3月在一家大型医疗中心所有偶然发现的LGIO增厚情况，并随后进行了内镜检查。
乙状结肠或直肠增厚的偶然发现患者中，96%、远端食管增厚患者中81%以及盲肠增厚患者中13%在进一步内镜检查时有显著异常。
尽管盲肠增厚时阳性病理结果比其他LGIO少见，但CT上所有这些偶然发现都需要进一步内镜检查。
