中文摘要：

为探讨原发性阑尾肿瘤的临床特点,提高阑尾肿瘤的诊治水平,本文回顾性分析本院2009年1月~2016年7月经手术治疗的原发性阑尾肿瘤30例患者临床资料。本组30例患者临床表现主要为阑尾炎和腹部包块,均经手术和病理确诊,包括黏液性肿瘤19例,阑尾腺癌8例,阑尾类癌2例,恶性淋巴瘤1例。行右半结肠切除术3例,行回盲部切除术8例,15例行单纯阑尾切除,其他手术方式4例。随访25例,2例腺癌术后死于其他疾病,1例粘液性肿瘤死于白血病,1例腺癌于术后10个月复发,余均无复发和转移。阑尾肿瘤临床少见,缺乏特异临床表现,术前诊断困难,主要依靠术中快速冰冻切片和术后病理确诊。手术为主要的治疗方法,术式选择是影响预后的关键因素。

英文摘要：

To investigate the clinical features and to improve the accuracy diagnosis and treatment of the disease.The clinical data of 30 patients with primary tumors of the appendix in our hospital from January 2009 to July 2016 were retrospectively studied.Appendicitis and abdominal mass were the major clinical manifestations of primary appendix tumors.All 30 patients received surgical operation and confirmed by the histopathological diagnosis.The primary appendix tumors included mucinous tumor in 19 cases,appendix adenocarcinoma in 8cases,appendix carcinoid in 2cases,and malignant lymphoma in 1case.All of them were treated with surgical resection.Right hemicolectomy were performed in 3cases,ileocecal resection in 8cases,single appendectomy in 15 cases,and other operation patterns in 3cases.The 2cases with adenocarcinoma died of other diseases,one case with mucinous tumor died of leukemia,one case with adenocarcinoma was performed because of tumor recurrence at 10 months after operation respectively.Appendix tumors which lack specific clinical features are uncommon and difficult to be diagnosed,and the diagnosis mainly relies on rapid and postoperative pathological examinations.Operation is a principle therapy,operation choice is important for improving the prognosis of appendicular tumor.
