title: Determining Predictors for Intra-abdominal Septic Complications Following Ileocolonic Resection for Crohn's Disease-Considerations in Pre-operative and Peri-operative Optimisation Techniques to Improve Outcome.
abstract: OBJECTIVE
  Intra-abdominal septic complications [IASC] following ileocolonic resection for Crohn's disease are common. Determining risk factors for these complications can aid pre-operative and peri-operative strategies to reduced morbidity. This study aims to determine the incidence and predictors of intra-abdominal septic complications following ileocolonic resection for Crohn's disease.
  
  
  METHODS
  A single-centre, retrospective study was conducted. The clinical case notes of patients with histopathologically proven Crohn's disease, who underwent an ileocolonic resection as a one-stage or two-stage procedure, were reviewed. The primary endpoint was the formation of intra-abdominal septic complications within a 30-day post-operative time frame.
  
  
  RESULTS
  Overall 163 patients underwent 175 ileocolonic procedures. Post-operative intra-abdominal septic complications were demonstrated in 9% [13/142] of one-stage procedures and 12% [4/33] of two-stage procedures [p = 0.2]. Post-operative IASCs following a one-stage procedure demonstrated associations with smokers [p = 0.004], intraoperative abdominal sepsis [p = 0.005], concomitant upper gastrointestinal Crohn's [p = 0.015], the presence of peri-operative anaemia [p = 0.037], hypoalbuminaemia [< 25g/l] [p = 0.04], and histologically involved margins [p = 0.001]. Multivariate analysis demonstrated the presence of intra-abdominal sepsis (hazard ratio [HR] 8.6, 95% confidence interval [CI]: 1.2 60.1] and the use of peri-operative biologicals [HR 24.6, 95% CI: 2.0-298] as independent predictors of post-operative intra-abdominal septic complications.
  
  
  CONCLUSIONS
  This study highlights specific variables that may be contributory to poor outcome. These findings may be important when optimising patients for surgery, as well as planning an appropriate operative strategy. Further prospective studies and a larger sample size are required to validate these findings.
