This study was aimed at assessing the role of CT-hypotonic gaseous duodenography in the study of the pancreatic-duodenal region. Forty-two patients with malignancies in this region were examined with CT of the upper abdomen followed by CT-hypotonic gaseous duodenography (30 pancreatic head cancers, 7 main bile duct and 5 ampullary lesions). In 20 of 28 cases of pancreatic head carcinoma, CT-hypotonic gaseous duodenography yielded more pieces of information than baseline abdominal CT and was also more useful in small pancreatic head cancers, < 4 cm diameter. In 4 of these patients, CT-hypotonic gaseous duodenography better demonstrated the pancreatic lesions which conventional CT had demonstrated poorly. In contrast, CT-hypotonic gaseous duodenography was less useful in main bile duct carcinomas, depicting focal duodenal infiltration in only 1 of 7 cases. In all ampullary tumor patients (5/5), CT-hypotonic gaseous duodenography demonstrated intraduodenal lesions. The authors conclude that CT-hypotonic gaseous duodenography is a useful technique to investigate small pancreatic head cancers and the method of choice to demonstrate ampullary lesions.
本研究旨在评估CT低张气体十二指肠造影在胰十二指肠区域研究中的作用。对该区域的42例恶性肿瘤患者进行上腹部CT检查，随后进行CT低张气体十二指肠造影（30例胰头癌、7例胆总管病变和5例壶腹病变）。在28例胰头癌病例中的20例中，CT低张气体十二指肠造影比基线腹部CT提供了更多信息，并且对直径<4 cm的小胰头癌也更有用。在其中4例患者中，CT低张气体十二指肠造影能更好地显示传统CT显示不佳的胰腺病变。相比之下，CT低张气体十二指肠造影在胆总管癌中作用较小，仅7例中的1例显示局灶性十二指肠浸润。在所有壶腹肿瘤患者（5/5）中，CT低张气体十二指肠造影均显示十二指肠内病变。作者得出结论，CT低张气体十二指肠造影是研究小胰头癌的有用技术，也是显示壶腹病变的首选方法。
