More than 50% of patients with Crohn’s disease (CD) require intestinal resection at least once during the course of their disease. Patients with Rutgeerts score i0 and i1 have a favourable clinical course, whereas Rutgeerts score > i2 is associated with higher risk of developing symptoms and complications. The aim of this study was to explore the incidence and management of postoperative recurrence in a population of CD patients from the Practicrohn study.


Practicrohn was a retrospective study performed in 26 Spanish hospitals, including patients aged ≥ 18 years old who underwent CD-related ileocolonic resection between January 2007 and December 2010. Patient’s data before and up to 5 years after surgery were collected retrospectively from medical records. Clinical recurrence was defined as suggestive clinical symptoms (diarrhoea, abdominal pain, abscess, or mass) and one of the following: endoscopic Rutgeerts score ≥ 2 and/or CT or MRI confirmatory of disease activity, performed within 6 months of symptoms. Categorical variables were compared with the χ2 test or Fisher’s exact test Kaplan–Meier method was used to assess time to clinical recurrence and a log-rank test to obtain the statistical significance.


In total, 314 patients were analysed (mean age 40 years [SD 13], 48% men). Of these, 149 (51%) were smokers at CD diagnosis, and 115 (77%) kept on smoking at the time of surgery. Median time from CD diagnosis to surgery was 6 years (IQR 1–12). Indication for surgery was 147 (48%) stenosing, 98 (32%) penetrating disease, 46 (15%) stenosing+penetrating, and 14 (4%) refractoriness to medical treatment. Further, 208 (68%) of patients received preventive therapy for recurrence after surgery: 13% aminosalycilates, 9% antibiotics, 46% immunomodulators (IMM), and 1% anti-TNFs. Moreover, 97patients (31%) met the predefined criteria of clinical recurrence (median time to recurrence 315 days (IQR 65–748)). Cumulative probability of clinical recurrence was 16%, 27%, and 31% at 1, 3, and 5 years, respectively. Clinical recurrence was 25% in patients with IMM prophylactic therapy and 41% without prophylaxis (p = 0.014). During follow-up, 44 patients (14%) needed surgical reintervention with median time to surgical reintervention of 228 days IQR 25–75 (133–527).

Almost one-third of CD patients who underwent intestinal resection do not start early prophylaxis for recurrence. The risk of clinical recurrence in clinical practice was about 30 % within the first 5 years after surgery; only IMM seemed to reduce it, and 14% of the patients needed surgical reintervention.
