原发性十二指肠癌的诊治与预后分析
Diagnosis and treatment of primary duodenal carcinoma
目的 探讨原发性十二指肠癌的诊断、治疗及影响预后的因素.方法 回顾性分析2000年6月至2007年6月间经手术治疗的41例原发性十二指肠癌患者的临床资料. 结果本组原发性十二指肠癌的临床表现无特异性,可有腹痛、腹胀、黄疸、呕吐以及上消化道出血等表现.术前纤维十二指肠镜确诊率为86%,十二指肠低张造影诊断率为90%,B超检查阳性率为20%,CT扫描诊断正确率为33%.对23例行胰头十二指肠切除术,6例节段性肠管切除术,9例短路手术,剖腹探查取活检术3例.患者术后5年生存率为18%.单因素分析结果显示:手术方式、病理类型、原发肿瘤浸润深度、淋巴结转移与预后相关;多因素回归分析显示:手术方式、原发肿瘤浸润深度和淋巴结转移是影响原发性十二指肠癌患者术后生存的独立因素.结论 十二指肠低张X线造影和纤维胃十二指肠镜是诊断十二指肠癌的主要手段.胰十二指肠切除术是原发性十二指肠癌的首选治疗方法.
更多Objective To evaluate the diagnosis, treatment and prognosis of primary duodenal carcinoma. Methods The clinical data of 41 cases with primary duodenal carcinoma admired during 2000-2007 were analyzed retrospectively. Results Clinical manifestation was not specific, including abdominal pain, abdominal distention, jaundice, bowel obstruction or bleeding. The correct diagnosis rate of endoscopy, duodenography, ultrasound and CT was 86%, 90%, 20% and 33% respectively. 23 cases underwent pancreaticoduodenectomy, 6 cases received segmental duodenectomy, 9 cases received bypass operation and 3 cases underwent biopsy. Overall postoperative 5-year survival rate was 18%. Univariate analysis revealed that the operation types, tumor histology, depth of tumor invatian, lymphatic invasion correlated with prognosis. Multivariate analysis showed that only the operative types, depth of tumor invasion and lymphatic invasion were independent prognostic factors. Conclusions Duodenography and endoscopy are major methods for diagnosis of primary duodenal carcinoma. Pancreaticoduodenectomy is the choice of therapy for primary duodenal carcinoma.
