In a retrospective study, 79 patients with gastric (n = 59) or duodenal (n = 20) wall thickening on conventional abdominal ultrasonograms were included. To reduce bias, patients with a microscopic diagnosis of upper GI neoplasia present at the time of scanning were excluded. The final diagnosis was based upon endoscopy, operation, upper GI series, or autopsy. Among the 59 cases of gastric wall thickening, 33 (56%) proved to be gastric cancer, one (2%) was benign neoplasia, and 17 (29%) showed nonneoplastic pathology (ulcer, gastritis, fibrosis). In eight cases (13%) no gastric pathology was present in the final diagnosis, thus producing false-positive sonographic diagnoses. Among the 20 cases of duodenal wall thickening, five (25%) proved to be duodenal cancer and seven (35%) showed nonneoplastic duodenal pathology. We concluded that gastric or duodenal wall thickening shown on abdominal sonography is a significant finding indicating upper GI pathology (malignant or nonmalignant) in a high percentage of the gastric (86%) and duodenal (60%) cases.
在一项回顾性研究中，纳入了79例在传统腹部超声检查中出现胃壁增厚（n = 59）或十二指肠壁增厚（n = 20）的患者。为减少偏倚，排除了扫描时经显微镜诊断为上消化道肿瘤的患者。最终诊断基于内镜检查、手术、上消化道造影或尸检。在59例胃壁增厚病例中，33例（56%）被证实为胃癌，1例（2%）为良性肿瘤，17例（29%）显示为非肿瘤性病变（溃疡、胃炎、纤维化）。8例（13%）最终诊断未发现胃部病变，从而产生了超声检查的假阳性诊断。在20例十二指肠壁增厚病例中，5例（25%）被证实为十二指肠癌，7例（35%）显示为非肿瘤性十二指肠病变。我们得出结论，腹部超声显示的胃壁或十二指肠壁增厚是一个重要发现，表明在高比例的胃（86%）和十二指肠（60%）病例中存在上消化道病变（恶性或非恶性）。
