Purpose: Almost 50% of patients with inflammatory bowel disease (IBD) will undergo surgery for their disease at some stage of its clinical course. Surgery in IBD is not usually followed by clinical remission and may result in various post operative complications. The purpose of this review is to characterize the factors that may have an influence on the risk of surgery in patients with IBD.Table: [1685]Methods: A retrospective chart review of 792 IBD patients was done of which 243 patients had surgery. All the factors that had an influence on the incidence of surgery were identified. Odds ratio (OR) and p value were calculated using the Fischer exact test for nominal data and T test for continuous data. Results: Out of the 792 patients 30.7% (n=243) had surgery, of which 86% (n=208, OR 7.65, p value <0.05) had CD, 14% (n=35) had UC. Of these patients 56% (n=137, OR 0.91, P value not significant) were females and 44% (n=106) were males. The average age among those who had surgery was 46±15 years (p value< 0.05), average duration of disease was 16±12.5years (p<0.05), average HBI/Lichtiger score was 7.7±6 (p value<0.05), cumulative duration of steroid use was 45±82 months (p<0.05), average Calprotectin was 373.5±591 mcg/g (p value not significant) and average BMI was 26±6 (p value not significant). The other factors that had significant effect on the increase in surgery rates were CRP>2 mg/dl 26% (n=63, OR 1.96, p<0.05), anemia 43% (n=104, OR 1.43, p<0.05) and use of biologic agent 49% (n=118, OR 3.2, p<0.05). Average duration of biologics in patient who underwent surgery was 26.7±28.5 months as compared to 16.4±25.8 months in those who have not had surgery yet. Conclusion: Factors that increased the risk of surgery rates in IBD patients were age, duration of disease, HBI/Lichtiger score, cumulative duration of steroid use, CRP>2, anemia and use of biologic agent. Biologic agents do not offer long term risk reduction of surgery.
