十二指肠隆起性病变98例分析

目的：探讨十二指肠粘膜隆起性病变的内镜表现和病理间的关系。方法：回顾性分析98例十二指肠粘膜隆起性病变的内镜特点,并对活检标本行HE染色,光镜下观察。结果：内镜下表现为单个或多个结节状病变。病理确诊慢性炎症50例（其中1例为十二指肠结核）,增生性息肉20例,腺瘤样息肉10例,腺癌12例,高分化乳头状腺癌2例,异位胰腺2例,壶腹癌1例,鳞癌1例。结论：十二指肠粘膜隆起性病变以慢性炎症为最多见,其次为息肉样病变,恶性病变约占16％,确诊有赖于病理检查。     

闭合性十二指肠损伤几种术式的选择与评价

原发性十二指肠腺癌的影像诊断分析

目的探讨原发性十二指肠腺癌影像学诊断的价值。方法回顾性分析,11例经手术证实的原发性十二指肠腺癌的数字胃肠低张气钡双重造影及CT平扫和增强的影像资料。结果双重造影表现为十二指肠局限性狭窄,不规则充盈缺损及龛影,黏膜破坏,近端肠管扩张;CT检查表现为十二指肠壁增厚,管腔狭窄伴软组织肿块,增强扫描显示肿块明显不均匀强化。结论数字胃肠低张气钡双重造影及CT平扫与增强检查,对原发性十二指肠腺癌的诊断与鉴别诊断有重要价值。     

原发性十二指肠癌的外科治疗及预后分析

目的 探讨原发性十二指肠癌的临床病理特点、外科治疗方法和预后.方法 同顾性分析经外科治疗的86例十二指肠癌患者的临床病理资料并进行随访.结果 86例十二指肠癌患者的临床表现主要为上腹部疼痛、黄疽、贫血、消化道梗阻、黑便和体重下降.肿瘤位于十二指肠球部4例,降部66例,水平部12例,升部4例.B超、CT、MRI、十二指肠镜及十二指肠低张造影的诊断率分别为41.7%、69.4%、75.0%、84.0%和80.9%.86例患者均行手术治疗,其中行根治性手术切除38例,行姑息性手术45例,行削腹探查术3例.根治性切除组和姑息性手术组患者的中位生存时间分别为42个月和13个月,差异有统计学意义(P<0.05).结论 原发性十二指肠癌的临床表现无特异性,早期诊断并行根治性手术切除是改善预后的有效手段.     

十二指肠恶性肿瘤的影像诊断

目的回顾性分析十二指肠恶性肿瘤的影像所见。方法原发肿瘤１３例,继发肿瘤３例,１６例病人均行上消化道气钡双重造影。５例病人行ＣＴ检查,２例行血管造影,２例壶腹部癌行Ｂ超检查,其中１例行ＥＲＣＰ检查。结果所有病人均经手术切除,将Ｘ线所见与病理结果对照分析,腺癌７例,平滑肌肉瘤６例,继发性癌３例。结论消化道造影是十二指肠病变的首选检查方法。本组病例均能提示病变部位,其中１３例定性诊断正确,但对一些外生性肿瘤,造影有其局限性,应结合ＣＴ、Ｂ超综合诊断。     

保留十二指肠胰头全切除术

保留十二指肠胰头全切除术要点：采用柯克手法将胰头从后腹膜分离,直至见到肠系膜下静脉。沿着肠系膜上静脉解剖直至胰颈。结扎切断Henle静脉干。游离、悬吊胃十二指肠动脉,暴露门静脉。缝扎胰腺上下缘、结扎胰头以减少横断胰颈时的出血。切断胰腺勾突,残端缝扎止血。沿着胰头部实质与十二指肠之间的疏松结缔组织解剖,结扎从胰十二指肠动脉弓到胰头的分支。沿着胰头与胆总管之间解剖。切断主胰管,残端用5/0普理灵线缝扎。胰管空肠吻合采用胰管对粘膜吻合法。     

Inflammatory fibroid polyps in children:A new case report and a systematic review of the pediatric literature

AIM: To study that inflammatory fibroid polyps(IFPs) in children are extremely uncommon tumors that may occur throughout the gastrointestinal tract. METHODS: A systematic review of the pediatric literature and a report of a new case of IFP is also pres-ented. The Pub Med database was searched for original studies on pediatric IFPs since 1960, according to "Preferred reporting items for systematic reviews and meta-analyses" guidelines for systematic reviews. RESULTS: Five studies were finally enclosed, encompassing 6 children with IFPs(mean age 64 mo). Tumors were located in the stomach(2 patients), in the small bowel(2 patients), in the rectum(1 patient) and in the colon(1 patient). Open surgery was performed in all patients and complete excision of the mass was achieved in all cases. All patients are alive and free of symptom. Authors described a further case of a 3-year-old boy with a large duodenal IFP, in whom the tumor was removed by "en block resection". The presence of IFP throughout the gastrointestinal tract and its variable clinical appearances make it difficult to diagnose. An accurate pre-operative assessment is fundamental in order to differentiate IFP from other more aggressive gastrointestinal tumor, enabling unnecessary demolitive surgery. CONCLUSION: When complete resection of the IFP is achieved, the prognosis is excellent.
