In Crohn's disease natural history, about 80% of the patients require surgery, which is not curative: unfortunately, the disease recurs in many patients.
Dr Teresa Cammarota from Italy investigated the role of intestinal ultrasound to predict the risk of post-operative surgical recurrence in Crohn's disease.
The research team retrospectively enrolled a total of 196 patients, with ileal or ileocolonic Crohn's disease, undergoing intestinal resection.
All patients underwent bowel ultrasonography 6–15 months after resection.
The research team assessed that wall thickness at the anastomosis level was measured, and thickening 3 mm was evaluated as risk factor of long-term need for reoperation.

|Scandinavian Journal of Gastroenterology |
Patients who have a bowel wall thickness 3 mm have an risk ratio of surgical recurrence of 2.1 higher than those with a thickness of 3 mm.
Dr Cammarota's team concluded, "The absolute incidence of new surgical intervention is 13% in patients with bowel wall thickness of 3 mm, 28% in patients with thickness 3 mm, 29% with thickness 4 mm, 34% with thickness more than 5 mm, and 40% with thickness 6 mm."
"Bowel wall thickness 3 mm at ultrasound may be a non-invasive predictor of early surgical recurrence after ileo-colonic resection."
