Gastrointestinal involvement occurs in approximately 4% of cases of systemic amyloidosis. The most common site of amyloid deposition is small bowel, followed by stomach, colorectum and esophagus. Although rare, gastrointestinal amyloidosis may be associated with severe complications including gastrointestinal bleeding or perforation and may be mistaken for malignancy.
胃肠道受累约发生于系统性淀粉样变的 4%病例中。淀粉样物质最常沉积的部位是小肠，其次是胃、结肠直肠和食管。虽然罕见，但胃肠道淀粉样变性可能与严重并发症相关，包括胃肠道出血或穿孔，并可能被误诊为恶性肿瘤。
