Risk factors of reoperation in patients with Crohn's disease recurrence / 中华消化外科杂志

ABSTRACT

Objective 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 interval1.035-3.518,1.087-11.494,1.816-16.590,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.
