本文报道7例经纤维胃镜诊断的十二指肠癌,其中原发性十二指肠癌6例,肝细胞癌乳头内转移1例。除1例为乳头转移性肝细胞癌外,其余6例均为腺癌。临床症状以腹部疼痛、上消化道出血,梗阻、黄疸及腹部包块为主。X线常规钡餐的误诊率较高,纤维内窥镜对本病的确诊最有价值。 This article reported seven cases of duodenal cancer diagnosed by gastroscopy, including six cases of primary duodenal cancer and one case of intrahepatic metastasis of hepatocellular carcinoma. Except for 1 case of metastatic hepatocellular carcinoma of the papillary, the remaining 6 cases were adenocarcinoma. The clinical symptoms were abdominal pain, upper gastrointestinal bleeding, obstruction, jaundice and abdominal mass. The rate of misdiagnosis of X-ray conventional barium meal is higher, and fiber endoscope is the most valuable for definite diagnosis of this disease.
