Despite the numerous advances in medical treatment, it is estimated that a significant percentage of patients with IBD requires bowel resection at least once. The aim of this study was to evaluate patient characteristics and factors associated to surgical resection in patients with IBD in a tertiary IBD unit in Southeastern Brazil.


Retrospective analysis of data from 446 patients with IBD in follow-up at the University Hospital, Ribeirão Preto Medical School, from January 2000 up to December 2016. Medical records data comprised age, gender, disease type (Crohn’s disease [CD] or ulcerative colitis [UC]), disease location, disease behaviour, disease duration and smoking. Patients were divided into two groups: presence or absence of surgical resection.


Out of the 446 patients, 143 (111 CD and 32 UC) underwent surgical resection (53.2% female, 82.9% Caucasians, mean age: 45.49 ± 13.30 years). Main indications for surgery were: stenosis (10.3%), clinical intractability (6.5%) and massive haemorrhage (2.7%). Smoking (p = 0.0109, OR = 2.244; 95% CI: 1.237 to 4.056), stenotic phenotype (p < 0.0001, OR = 5.294; 95% CI: 3.073 to 9.1212), ileo-colonic location (p < 0.0001, OR = 3.447; 95% CI: 2.061 to 5.698) and longer disease duration (15.17 ± 9.19 vs. 7.94 ± 5.96 years) [p < 0.0001] were significantly associated with operations for CD. Longer duration (21.15 ± 21.58 vs. 9.79 ± 7.08 years) [p < 0.0001] and pancolitis (p = 0.0014; OR = 3.823; 95% CI: 1.698–8.605) were associated with surgical resection in UC. This results are summarised in Tables 1 and 2.

Clinical factors associated with higher risk of surgery in ulcerative colitis.

No significant differences were observed in relation to gender, race, age at diagnosis, and previous use of corticosteroids.


Need for surgical treatment is still frequent in patients with IBD. Smoking (current or past), longer disease time, stenotic phenotype, and ileo-colonic localisation in CD and more extensive disease in UC (pancolitis) were associated with a higher risk of surgery in our IBD Unit. Awareness about factors associated with unfavourable outcome allows these patients to be treated more appropriately.1
