Background. In Crohn's disease natural history, about 80% of the patients require surgery, which is not curative: unfortunately, the disease recurs in many patients. Objective. To investigate the role of intestinal ultrasound to predict the risk of post-operative surgical recurrence in Crohn's disease. Material and methods. A total of 196 patients, with ileal or ileocolonic Crohn's disease, undergoing intestinal resection, were retrospectively enrolled. All patients underwent bowel ultrasonography 6-15 months after resection. Wall thickness at the anastomosis level was measured, and thickening >3 mm was evaluated as risk factor of long-term need for reoperation. Results. Patients who have a bowel wall thickness >3 mm have an risk ratio (RR) of surgical recurrence = 2.1 [95% confidence interval (CI) = 1.12-3.74] higher than those with a thickness of ≤3 mm. The absolute incidence of new surgical intervention is 13% in patients with thickness of 3 mm, 28% in patients with thickness >3 mm, 29,1% with thickness >4 mm, 34% with thickness >5 mm, and 40% with thickness >6 mm. Conclusions. Bowel wall thickness >3 mm at ultrasound may be a non-invasive predictor of early surgical recurrence after ileo-colonic resection.
