摘要目的 探讨克罗恩病术后复发行再次手术的危险因素.方法 回顾性分析2004年3月至2013年9月中国医学科学院北京协和医院收治的108例克罗恩病行肠切除术患者的临床资料.其中82例患者行单次手术,26例行再次手术.分析可能影响克罗恩病患者术后复发行再次手术的25项因素,包括患者性别、年龄、血型、术前WBC、术前中性粒细胞、术前淋巴细胞、术前Hb、术前Alb、术前前白蛋白、超敏C-反应蛋白(hs-CRP)水平、抗酿酒酵母抗体(ASCA)表达、中性粒细胞胞质抗体(ANCA)表达、病变原发部位、疾病类型、肠外表现、肛周病变、吸烟史、阑尾手术史、初次手术前病程、初次手术前1年内使用免疫抑制剂、初次手术前BMI、术前小野寺预后营养指数(OPNI)、初次手术前应用肠内营养、是否急诊手术、初次术后并发症情况.单因素分析采用x2检验或Fisher确切概率法,多因素分析采用Logistic回归模型.结果 单因素分析结果表明:术前前白蛋白、hs-CRP、病变原发部位、疾病类型、吸烟史、初次手术前1年内使用免疫抑制剂及初次手术前应用肠内营养是克罗恩病患者术后复发行再次手术的危险因素(x2=5.928,4.805,7.491,12.363,5.229,9.026,16.506,P＜0.05).多因素分析结果表明:病变原发部位为回结肠型(L3型)、初次手术前1年内使用免疫抑制剂及初次手术前应用肠内营养制剂提供热量＜500 kcal/d是克罗恩病患者术后复发行再次手术治疗的独立危险因素(OR=1.908,3.535,5.489,95％可信区间:1.035～3.518,1.087 ～ 11.494,1.816 ～ 16.590,P＜0.05).结论 克罗恩病病变部位为回结肠型(L3型)、初次手术前1年内行免疫抑制剂治疗及初次手术前2周内每日肠内营养制剂提供热量＜ 500 kcal的患者有较高的复发再次手术风险.

abstractsObjective To investigate the risk factors of reoperation in patients with Crohn's disease recurrence.Methods The clinical data of 108 patients with Crohn's disease who were admitted to the Peking Union Medical College Hospital from March 2004 to September 2013 were retrospectively analyzed.Of the 108 patients,82 received single operation and 26 received reoperation.Twenty-five factors which might influence the reoperation were analyzed,which were gender,age,blood type,preoperative levels of white blood cells,neutrophils,lymphocytes hemoglobin,albumin,prealbumin,high sensitive-C reactive protein (hs-CRP),anti-saccharomyces cerevisiae antibody (ASCA),anti-neutrophil cytoplasmic antibody (ANCA),location and type of the lesions,extraintestinal manifestation,perianal lesions,history of smoking,appendectomy,course of the disease before the first operation,pre-operative administration of immunosuppressants,body mass index (BMI) before the first operation,onodera prognostic nutrition index (OPNI),enteral nutrition,emergent operation,complications after the first operation.The univariate analysis was done using the chi-square test or Fisher exact probability,and the multivariate analysis was done using the Logistic regression model.Results The results of univariate analysis showed that the level of preoperative prealbumin,hs-CRP,location and type of the lesion,the history of smoking,preoperative administration of immunosuppressants,enteral nutrition before the first operation were the risk factors of reoperation in patients with Crohn's disease (x2=5.928,4.805,7.491,12.363,5.229,9.026,16.506,P ＜ 0.05).The results of multivariate analysis showed that the lesion located at the ileocolon,administration of immunosuppressants prior to the first operation for 1 year and energy provided by enteral nutrition under 500 kcal/d before the first operation were the independent risk factors of reoperation (OR =1.908,3.535,5.489,95％ confidence interval:1.035-3.518,1.087-11.494,1.816-16.590,P＜0.05).Conclusions Patients with lesions located at the ileocolon,administration of immunosuppresants prior to the first operation for 1 year and energy provided by enteral nutrition under 500 kcal before the first operation have higher risk of Crohn's disease recurrence and reoperation.
