Frequency and risk factors of postoperative recurrence of Crohn's disease after intestinal resection in the Chinese population.
ABSTRACT Data on risk factors of postoperative recurrence in patients with Crohn's disease (CD) have shown conflicting results. The aim of this retrospective study is to identify predictors of early symptomatic recurrence of CD after surgical intestinal resection in the Chinese population.
Patients diagnosed as CD who underwent intestinal resection in Jinling Hospital between May 2004 and December 2010 were included in our study. Clinical data of these patients were reviewed. Multivariable survival analysis was performed to elucidate risk factors of early postoperative symptomatic recurrence.
There were a total of 141 CD patients who had at least one previous curative resection for CD under regular follow-up in our unit. Our data indicated disease behavior (95 % CI 1.01-1.70, P = 0.044), smoking habits (95 % CI 1.32-2.84, P = 0.001), indication of perforation (95 % CI 1.09-4.02, P = 0.026), and location of anastomosis (95 % CI 1.09-3.39, P = 0.023) which are, as a result, strong independent predictors of symptomatic recurrence, while the anastomosis type as side-to-side anastomosis (SSA) was significantly associated with a decreased risk of symptomatic recurrence when compared with other anastomosis type (95 % CI 0.26-0.94, P = 0.038). Medical prophylaxes also played a role in the prevention of postoperative symptomatic recurrence.
A smoking habits and perforation indication for surgery at the time of resection are associated with an increased risk of symptomatic recurrence. Anastomosis type with SSA is associated with a reduced risk of symptomatic recurrence. This population-based study supports the concept that environmental factors, disease character, and surgical technique influence the risk of postoperative symptomatic recurrence of CD.

ABSTRACT: Anastomotic recurrence after bowel resection is a major problem in Crohn's disease surgery. The aim of this study is to compare recurrence rate after stapled side-to-side ileo-colonic anastomosis to those after stapled end-to-side or hand-sewn side-to-side anastomosis to distinguish the role of suture technique and anastomotic configuration in the prevention of Crohn's disease recurrence. Eighty-four consecutive patients who had undergone ileo-colonic resection for Crohn's disease were enrolled: 12 of them had stapled side-to-side anastomosis, 36 stapled end-to-side anastomosis and 36 hand-sewn side-to-side anastomosis. We evaluated duration of operation, first bowel movement after operation, postoperative hospital staying, postoperative surgical complications, clinical recurrence and reoperation rate. The statistical analysis was performed using Student's t-test and Fisher exact test. Cumulative recurrence rates were compared using F Cox test and Kaplan-Meier method. No statistically significant difference between the three groups was observed in early postoperative follow up. The stapled side-to-side anastomosis group obtained a better symptom-free survival than the stapled end-to-side group (p=0.04). In the stapled and hand-sewn side-to-side groups reoperation rates were significantly lower than in the stapled end-to-side group (p=0.01 and p=0.05 respectively). All the three types of anastomosis were demonstrated to be equally safe in early postoperative outcome. A longer follow-up showed a significantly lower incidence of reoperation recurrence in the stapled and hand-sewn side-to-side anastomosis compared to the stapled end-to-side anastomosis group. This result may suggest the configuration of the anastomosis as the key point in the recurrence of anastomotic Crohn's disease.Hepato-gastroenterology 51(58):1053-7. · 0.77 Impact Factor

ABSTRACT: We evaluated the effect of potential clinical factors on surgical recurrence of ileal Crohn's disease after initial ileocolic resection. One hundred seventy-six patients with ileal Crohn's disease who underwent an ileocolic resection with anastomosis were identified from our database. The outcome of interest was time from first to second ileocolic resection. Survival analysis was used to assess the significance of the Montreal phenotype classification, smoking habit, a family history of inflammatory bowel disease and other clinical variables. In our final Cox model, a family history of inflammatory bowel disease (hazard ratio 2.24, 95 percent confidence interval 1.16-4.30, P = 0.016), smoking at time of initial ileocolic resection (hazard ratio 2.08, 95 percent confidence interval 1.11-3.91, P = 0.023) was associated with an increased risk of a second ileocolic resection while postoperative prescription of immunomodulators (hazard ratio 0.40, 95 percent confidence interval 0.18-0.88, P = 0.022) was associated with a decreased risk of a second ileocolic resection. Both a family history of inflammatory bowel disease and smoking at the time of the initial ileocolic resection are associated with an increased risk of a second ileocolic resection. Postoperative prescription of immunomodulators is associated with a reduced risk of surgical recurrence. This study supports the concept that both genetic and environmental factors influence the risk of surgical recurrence of ileal Crohn's disease.Diseases of the Colon & Rectum 07/2008; 51(8):1211-6. · 3.34 Impact Factor
