Risk of postoperative morbidity in patients having bowel resection for colonic Crohn’s disease

Background The aim of the present multicenter study was to analyze the incidence and risk factors associated with postoperative morbidity in patients who had colorectal resection for colonic Crohn’s disease. Methods Consecutive patients undergoing colorectal resection for colonic Crohn’s disease at seven surgical units in 1992–2017 were included. Exclusion criteria were: proctectomy for perianal disease, surgery for cancer, previous colectomies, surgery before 1998. Abdominal colectomy and proctocolectomy were defined as extended resections; all other operations were classified as segmental resections. Postoperative intraabdominal septic complications (IASC) were: anastomotic leaks, peritonitis and abscess. Results One hundred ninety-nine patients met the inclusion criteria: 116 patients had segmental resections and extended resections were performed in 83 patients. An anastomosis was constructed in 122 patients and an additional stoma was formed in 15 of those cases. Segmental resections were performed significantly more frequently in stricturing or penetrating disease (93% vs. 61%, p
