ABSTRACT
Objective To analyze the risk factors affecting postoperative incisional infection in Crohn's disease (CD) patients after bowel resection.Methods The retrospective case-control study was conducted.The clinicopathologieal data of 239 CD patients who underwent bowel resection in the Sixth Affiliated Hospital of Sun Yat-sen University between January 2007 and December 2016 were collected.All patients underwent bowel resection.Observation indicators(1) surgical situations;(2) follow-up;(3) risk factors analysis affecting postoperative incisional infection;(4) clinical factors affecting preoperative anemia.The follow-up using outpatient examination or ward diagnosis was performed to detect incisional infection within 30 days postoperatively up to January 2017.The normality test was done by Shapiro-Wilk.Measurement data with normal distribution were represented as x-±s,and comparison between groups was evaluated with the t test.Measurement data with skewed distribution were described as M (range),and comparison between groups was analyzed using the Wilcoxon ranksum test.The univariate analysis and multivariate analysis were done using the Logistic regression model.The P< 0.05 in univariate analysis was incorporated into multivariate analysis for analysis in the forward wald.Results (1) Surgical situationsof 239 patients,11 underwent emergency surgery and 228 underwent elective surgery;65 and 174 underwent respectively laparoscopic surgery and open surgery;179 received digestive tract reconstruction and anastomosis and 81 received enterostomy (21 combined with anastomosis and enterostomy).Among 239 patients,137,113,101,58,54 and 11 were complicated respectively with fiber stenosis,intestinal fistula,obstruction of small intestine,abscess,cellulitis and enterobrosis (some patients combined with multiple signs).(2) Follow-up239 patients were followed up at 30 days postoperatively.During the follow-up,48 with incisional infection were improved by symptomatic treatment.(3) Risk factors analysis affecting postoperative incisional infection① Results of univariate analysis showed that illness behavior,sedimentation rate of RBC > 20 mm/h,preoperative anemia,preoperative chronic intestinal fistula,open surgery,intraoperative fiber stenosis and intraoperative intestinal fistula were risk factors affecting occurrence of postoperative incisional infection [odds ratio (0R)=2.530,2.579,4.233,2.988,2.554,0.503,3.052,95% confidence interval (CI)1.218-2.259,1.141-5.833,1.598-11.210,1.522-5.864,1.082-6.029,0.265-0.954,1.555-5.993,P<0.05].② Results of multivariate analysis showed that preoperative anemia and intraoperative intestinal fistula were independent risk factors affecting occurrence of postoperative incisional infection (OR =3.881,2.837,95% CI1.449-10.396,1.429-5.634,P<0.05).(4) Clinical factors affecting preoperative anemiacases (male) with preoperative anemia,body mass index (BMI),cases with sedimentation rate of RBC > 20 mm/h,platelet (PLT) > 300x109/L,elevated C-reactive protein,albumin (Alb) <35 g/L were respectively 120,(17.4±2.9)kg/m2,130,75,139,65 in patients with preoperative anemia and 65,(18.3±2.9)kg/m2,36,12,39,10 in patients without preoperative anemia,with statistically significant differences (x2 =17.966,t =2.210,x2 =12.219,14.440,14.661,12.272,P<0.05).Conclusion The preoperative anemia and intraoperative intestinal fistula are independent risk factors affecting occurrence of postoperative incisional infection,and preoperative anemia is associated with perioperative inflammatory conditions.
