Brief Summary

BACKGROUND: Previous studies of short-term surgical outcomes after preoperative exposure to anti-TNF therapy in ulcerative colitis (UC) patients who have undergone IPAA have been conflicting. We sought to determine whether preoperative exposure to anti-TNF therapy affects histological measures of fibrosis in the colorectum, which may be a potential factor in adverse anastomosis complications following IPAA surgery. METHODS: Individuals who received infliximab as maintenance therapy and who received their last dose within 180 days of the first stage of IPAA were selected. The control group comprised UC patients who were not exposed to anti-TNF therapy, matched by age, sex, BMI, disease duration, albumin levels, and post-operative leak outcome. Hematoxylin and eosin- (H\&E) and trichrome-stained slides from the most distal, well-oriented, full-thickness section of colorectum from each patient's total colectomy specimen were evaluated. Blinded assessment of the degree of fibrosis in the lamina propria, the submucosa, the submucosa immediately adjacent to the muscularis propria, and the subserosa was performed by a single observer using a semi-quantitative pictorial scale.

Outcome Measures

Primary Outcomes (1)

  • to determine whether preoperative exposure to anti-TNF therapy affects histological measures of fibrosis in the rectum, as increased rectal fibrosis may be a potential factor in adverse anastomosis complications following IPAA surgery

    Assesment of the degree of fibrosis in the lamina propria, the subbmucosa, the submucosa immediately adjacent to the muscularis propria, and the subserosa was performed by a single observer using a semi-quantitative pictorial scale.

    all individuals with IBD who underwent IPAA from January 2002 to June 2013 were reviewed

Study Arms (2)

anti-TNF

UC patients treated with maintenance anti-TNF therapy who underwent IPAA surgery

Drug: Anti-TNF Drug

CONTROL GROUP

UC patients who were not exposed to anti-TNF therapy

Interventions

anti-TNF
