Urgent surgery, surgery without preoperative MBP, colorectal cancer, and fecal diversion were exclusion criteria. A polyethylene glycol solution (2 L) was used for MBP. OA consisted of paramomycin and metronidazole taken at 7 p.m. and 11 p.m. at the evening before surgery. Occurrence of complications at the anastomotic site (leakage, peritonitis, abscess, or fistula in direct proximity to the anastomosis) was a primary outcome measure. Complications of MBP were recorded. Mechanical bowel preparation was defined as \u201cincomplete\u201d when patients took a lesser amount of MBP solution than scheduled.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Between 2016 and 2024, ileocolic or colorectal resections with formation of an anastomosis were performed in 284 patients with Crohn\u2019s disease. Nausea, vomiting, or abdominal pain occurred during the MBP in 29% of patients (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200978), leading to termination of intake in 53 patients (19%)\n                      <jats:bold>.<\/jats:bold>\n                      Women (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), patients hospitalized urgently because of acute abdominal pain (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.008), patients presenting with severe anemia before surgery (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007), and patients scheduled for resections completed by ileocolic anastomosis as opposed to colocolic or colorectal anastomosis (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.01) demonstrated a significantly increased risk of incomplete MBP. Thirty-two percent of patients demonstrated apparent dilatation of small bowel at the time of surgery.
