Patients with abscesses, compared to patients without abscess, had a 1.24 relative risk (RR) of undergoing a surgical diversion procedure (95% CI, 1.14-1.34, P\u2009&amp;lt;\u2009.001). Patients with known abscesses not drained preoperatively, compared to no abscess, had an RR of 1.69 for diversion (P\u2009&amp;lt;\u2009.001, 95% CI, 1.28-2.22). Patients who had a drain removed prior to surgery had a 1.7 RR for diversion (95% CI, 1-2.91, P\u2009=\u2009.05). However, patients who had a drain placed and kept until surgery did not have a significantly different rate of diversion compared to those without an abscess (P\u2009=\u2009.16).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Penetrating terminal ileitis with abscesses was associated with adverse outcomes after ileocolic resection for Crohn disease.
