BACKGROUND: Rates of postoperative complications are particularly high among patients with Crohn’s disease.
OBJECTIVE: The aim of this study was to assess whether positive inflammatory histological margins, among other factors, pose a risk for intra-abdominal septic complications in patients with Crohn’s disease undergoing ileocolic resection.
DESIGN: A retrospective study of patient records, during 2000–2010, was conducted.
SETTINGS: This investigation was performed at a single medical center.
PATIENTS: Included were 166 individuals with Crohn’s disease (85 males, mean age 35.6).
INTERVENTION: Ileocolic resection with primary anastomosis was performed.
MAIN OUTCOME MEASURE: The primary outcomes measured were postoperative intra-abdominal septic complications.
RESULTS: Twenty-five patients (15%) developed intra-abdominal septic complications, including anastomotic leak, intra-abdominal abscesses and collections, and enterocutaneous fistulas. There were no postoperative deaths. Univariate analysis revealed that a long course of disease before surgery, an emergency surgery, steroid treatment of more than 3 months before surgery, additional sigmoidectomy, and positive surgical margins detected on histopathological examination were associated with intra-abdominal septic complications. In a multivariate analysis, only disease duration longer than 10 years (OR 4.575 (CI 1.592–13.142), p = 0.005), additional sigmoidectomy (OR 5.768 (CI 1.088–30.568), p = 0.04), and positive histological resection margins (OR 2.996 (CI 1.085–8.277), p = 0.03) were found to be independent risk factors.
LIMITATIONS: This study was limited by the incomplete data regarding preoperative albumin levels.
CONCLUSIONS: Positive histological margins, disease duration of more than 10 years, and added sigmoidectomy are independent risk factors that are associated with postoperative intra-abdominal septic complications in patients undergoing ileocolic resection for Crohn’s disease. These risk factors should be considered when the need for a diverting stoma is questionable. A frozen section of the margins may assist in the decision as to a temporary ileostomy construction.
