Abstract: PURPOSE: The impact of infliximab (IFX) on postoperative complications in surgical patients with Crohn's disease (CD) and ulcerative colitis (UC) is unclear. We examined a large patient cohort to clarify whether a relationship exists between IFX and postoperative complications. METHODS: A total of 413 consecutive patients--188 (45.5%) with suspected CD, 156 (37.8%) with UC, and 69 (16.7%) with indeterminate colitis--underwent abdominal surgery at the Massachusetts General Hospital between January 1993 and June 2007. One hundred one (24.5%) had received preoperative IFX < or = 12 weeks before surgery. These patients were compared to those who did not receive IFX with respect to demographics, comorbidities, presence of preoperative infections, steroid use, and nutritional status. We then compared the cumulative rate of complications for each group, which included deaths, anastomotic leak, infection, thrombotic complications, prolonged ileus/small bowel obstruction, cardiac, and hepatorenal complications. Potential risk factors for infectious complications including preexisting infection, pathological diagnosis, and steroid or IFX exposure were further evaluated using logistic regression analysis. RESULTS: Patients were similar with respect to gender (IFX = 40.6% men vs. non-IFX = 51.9%, p = 0.06), age (36.1 years vs. 37.8, p = 0.43), Charlson Comorbidity Index (5.3 vs. 5.7, p = 0.25), concomitant steroids (75.3% vs. 76.9%, p = 0.79), preoperative albumin level (3.3 vs. 3.2, p = 0.36), and rate of emergent surgery (3.0% vs. 3.5%, p = 1.00). IFX patients had higher rates of CD (56.4% vs. 41.9%, p = 0.02), concomitant azathioprine/6-mercaptopurine use (34.6% vs. 16.6%, p < 0.0001), and lower rates of intra-abdominal abscess (3.9% vs. 11%, p < 0.05). After surgery, the two groups had similar rates of death (2% vs. 0.3% p = 0.09), anastomotic leak (3.0% vs. 2.9%, p = 0.97), cumulative infections (5.97% vs. 10.1%, p = 1), thrombotic complications (3.6% vs. 3.0%, p = 0.06), prolonged ileus/small bowel obstructions (3.9 vs. 2.8, p = 0.59), cardiac complications (1% vs. 0.6%, p = 0.42), and hepatic or renal complications (1.0 vs. 0.6% p = 0.72). A logistic regression model was then created to assess the impact of IFX, as well as other potential risk factors, on the rates of cumulative postoperative infections. We found that steroids (odds ratio [OR] = 1.2, p = 0.74), IFX (OR 2.5, p = 0.14), preoperative diagnosis of CD (OR = 0.7, p = 0.63) or UC (OR = 0.6, p = 0.48), and preoperative infection (OR = 1.2, p = 0.76) did not affect rates of clinically important postoperative infections. CONCLUSIONS: Preoperative IFX was not associated with an increased rate of cumulative postoperative complications.

Abstract: BACKGROUND & AIMS: Postoperative morbidity and mortality following a colectomy for ulcerative colitis (UC) has been primarily reported from tertiary care referral centers that perform a high volume of operations; however, the postoperative outcomes among nonselected hospitals are not known. We set out to evaluate postoperative morbidity and mortality using a nationally representative database and to determine the factors that influenced outcomes. METHODS: We analyzed the 1995-2005 Nationwide Inpatient Sample to identify 7108 discharges for UC patients who underwent a total abdominal colectomy. The effects of hospital volume on postoperative morbidity and mortality were evaluated in logistic regression models adjusting for demographic and clinical factors. RESULTS: Postoperative mortality and morbidity rates were 2.3% and 30.8%, respectively. Most operations were performed in low-volume hospitals that had an increased risk of death (adjusted odds ratio [aOR], 2.42; 95% confidence interval [CI]: 1.26-4.63). In-hospital mortality was increased in patients who were admitted emergently (aOR, 5.40; 95% CI: 3.48-8.40), aged 60-80 years (aOR, 8.70; 95% CI: 3.30-22.92), and those with Medicaid (aOR, 4.29; 95% CI: 2.13-8.66). Emergently admitted UC patients whose surgery was performed 6 days after their admission had significantly increased likelihood of in-hospital death (aOR, 2.12; 95% CI: 1.13-3.97). CONCLUSIONS: Postoperative mortality was lowest in hospitals that performed the highest volume of operations. Increasing the proportion of total colectomies performed in high-volume hospitals may improve clinical outcomes for patients with UC.
