Postoperative complication rate can be up to 40% after surgery for ileocolonic Crohn’s disease. Risk factors of morbidity, especially the role of anti-tumour necrosis factor (TNF) therapy before surgery, remain controversial and have never been evaluated in a large prospective cohort study.


From September 2013 to September 2015, data on 592 consecutive patients who underwent surgery for ileocolonic CD at 19 French academic centres were collected prospectively in the RICCO registry held by the GETAID chirurgie group. We tested the possible relationships between anti-TNF therapy and postoperative overall morbidity by univariate and multivariate logistic regression analyses. Because treatment by anti-TNF is possibly dependent of patients and disease characteristics, a propensity score was calculated and introduced in the analyses using adjustment on inverse probability of treatment-weighted (IPTW) method.


Postoperative mortality, overall morbidity, and intra-abdominal septic morbidity rates in the entire cohort were 0%, 29.7%, and 8.4%, respectively. In total, 137 (23.1%) patients had received anti-TNF < 6 months before surgery. Overall morbidity rates in patients with or without preoperative anti-TNF were 41% and 26%, respectively (p = .001). Intra-abdominal septic morbidity rates in patients with or without preoperative anti-TNF were and 13% and 7.1% respectively (p = 0.03). In multivariate analysis, anti-TNF < 6 months before surgery was identified as an independent risk factor of overall postoperative morbidity (odds ratio [OR] = 1.99; confidence interval [CI] 95% = 1.17 – 3.39; p = 0.011), along with preoperative haemoglobin < 10 g/dL (OR = 4.77; CI 95% = 1.32 – 17.35; p = 0.017), operative time > 180 minutes (OR = 2.71; CI 95% = 1.54–4.78; p = 0.0006), and recurrent Crohn’s disease (OR = 1.95 CI 95% = 1.13 – 3.36; p = 0.017). After calculation of propensity score and adjustment according to the IPTW method, anti-TNF < 6 months before surgery remained a strong predictor of overall postoperative morbidity (OR = 2.10, CI 95% = 1.60–2.75, p <.0001) and postoperative intra-abdominal septic morbidity (OR = 3.13; CI 95% = 2.07–4.73; p <0.001).


Preoperative anti-TNF therapy increases the risk of morbidity after surgery for ileocolonic Crohn’s disease. This information should be taken into account for surgical management of these patients, especially with regard to preoperative preparation (nutritional support and antibiotics) and indication of temporary defunctioning stoma.
