原发性十二指肠良性肿瘤的诊断和外科治疗

目的探讨十二指肠良性肿瘤的诊断及治疗方法。方法回顾分析1988年10月至2001年10月经手术、病理证实的14例十二指肠良性肿瘤的临床资料。结果Brunner腺瘤5例,间质瘤4例,平滑肌瘤2例,血管瘤2例,脂肪瘤1例。上腹部不适(64%)、原因不明的上消化道出血(50%)和腹痛(20%)为本组患者的主要表现。本组患者术前均行胃镜检查,仅发现1例十二指肠球部肿瘤;5例行十二指肠镜检查,4例发现肿瘤;9例行十二指肠低张造影检查,8例明确见到肠腔内占位性病变;3例予急诊数字减影血管造影检查均发现病灶;2例行B超、CT检查,1例提示十二指肠肿瘤;11例患者(79%)术前经检查获确诊。全组患者均行外科手术切除肿瘤,围手术期死亡1例;13例术后获2～11年随访,未见复发。结论上腹部不适或上消化道出血是十二指肠良性肿瘤最常见的症状;十二指肠低张造影及十二指肠镜检查是最主要的检查手段;手术切除肿瘤是首选的治疗方法。

Diagnosis and treatment of benign duodenal tumor

OBJECTIVE: To investigate the diagnosis and treatment of benign duodenal tumor. METHODS: Clinical data of 14 patients with benign duodenal tumor confirmed pathologically or by operation from Oct.1988 to Oct.2001 were analyzed retrospectively. RESULTS: Of 14 patients, 5 had Brunner's grand adenoma, 4 mesenchymoma, 2 leiomyoma, 2 hemangioma, 1 lipoma. Upper abdominal discomfort (64% ), gastrointestinal bleeding(50% ) and abdominal pain(20% ) were common manifestations. All cases received gastroscopy and only one case was diagnosed. Five cases received duoenoscope and the diagnosis was confirmed in 4 cases. Nine cases received hypotonic duodenography and lesions were found in 8 cases. Digital subtraction angiography was performed in 3 cases and detected all lesions. Computed tomographic scan and B-ultrasound were performed in 2 cases and only one case was diagnosed. Eleven cases (79% ) got definite diagnosis before operation. Tumor resection was performed in all patients. Perioperative death occurred in one patient. No recurrence occurred in 13 cases after following up from 2 to 11 years. CONCLUSION: Upper abdominal discomfort and gastrointestinal bleeding are common features in patients with benign duodenal tumor. Duodenoscopy and hypotonic duodenography are good diagnostic approaches. Surgical tumor resection is the first choice of treatment.
