P237 Superior predictive value of intestinal ultrasound over endoscopic severity for colectomy risk in patients with ulcerative colitis

Abstract

i390 Poster presentations and the number of cases having ulcerations exclusively at the inverted stapled line. Results: Of the 82 patients included in the CD cohort, ulcerations were present in 63/82 (76·8%) at the inverted-versus 1/71 (1·4%) at the everted stapled line. Likewise in the CRC cohort, ulcerations were present in 4/6 (67·7%) at the inverted versus 0/6 (0%) at the everted stapled line. 27% of the 63 patients in the CD cohort had ulcerations exclusively on the inverted stapled line. Conclusion: Inverted stapled lines heal with ulcerations, whereas the everted stapled line heal without any ulcerations, both in CD and non-CD patients. The abnormalities at the inverted stapled line might interfere with endoscopic scoring of recurrence, with potentially an impact on patients' quality of life and on health-care costs if postoperative treatment is initiated incorrectly.
