The rate of postoperative complications is relatively high in CD patients but might be even higher in CD with morbid obesity (MO).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective study using a prospectively maintained database of all patients undergoing Ileocolic resection for CD between 2014 and 2021 in two referral centres, comparing postoperative complication rates according to BMI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three hundred and forty\u2010six patients were identified.

MO in this setting is associated with statistically non\u2010significant increases in all surgical complications, severe complications, readmission, and a higher chance for a bailout stoma creation upon reoperation. However, MO seems to be a protective factor for medical postoperative complications, which might suggest better nutritional
