Risk factors for colorectal neoplasia in inflammatory bowel disease: a nested case-control study from Copenhagen county, Denmark and Olmsted county, Minnesota.

OBJECTIVES: Population-based data on risk factors and protective factors for colorectal dysplasia and cancer in patients with inflammatory bowel disease (IBD) are sparse. We conducted a nested case-control study of such factors in two well-described IBD cohorts from Copenhagen County, Denmark and Olmsted County, Minnesota. METHODS: Forty-three neoplasia cases were matched on six criteria to 1-3 controls (N = 102). Medical records were scrutinized for demographic and clinical data. For each variable, the odds of neoplasia were estimated using conditional logistic regression. RESULTS: Primary sclerosing cholangitis (PSC) (odds ratio [OR] 6.9, 95% confidence interval [CI] 1.2-40), percentage of disease course with clinically active disease (OR [per 5% increase] 1.2, 95% CI 0.996-1.4), and >or=1 yr of continuous symptoms (OR 3.2, 95% CI 1.2-8.6) were associated with neoplasia, whereas a borderline association with median number of small-bowel x-rays (OR 1.3, 95% CI 0.96-1.6) was observed. We did not observe a protective effect of frequency of physician visits (OR 1.4, 95% CI 0.96-2.0), number of colonoscopies (OR 1.4, 95% CI 1.0-2.1), cumulative dose of sulfasalazine (OR [per 1,000 g] 1.1, 95% CI 1.0-1.3) and mesalamine (OR [per 1,000 g] 1.3, 95% CI 0.9-1.9), or partial intestinal resections (OR 1.5, 95% CI 0.3-7.1). CONCLUSIONS: Subgroups of IBD patients-those with PSC, severe long-standing disease, and exposure to x-ray-were at greater risk of colorectal neoplasia. The protective effect of close follow-up, colonoscopy, and treatment with 5-aminosalicylates was questionable.

Update on the incidence and prevalence of Crohn's disease and ulcerative colitis in Olmsted County, Minnesota, 1940-2000.

BACKGROUND: We previously reported that the prevalence of Crohn's disease (CD) and ulcerative colitis (UC) in Olmsted County, Minnesota, had risen significantly between 1940 and 1993. We sought to update the incidence and prevalence of these conditions in our region through 2000. METHODS: The Rochester Epidemiology Project allows population-based studies of disease in county residents. CD and UC were defined by previously used criteria. County residents newly diagnosed between 1990 and 2000 were identified as incidence cases, and persons with these conditions alive and residing in the county on January 1, 2001, were identified as prevalence cases. All rates were adjusted to 2000 US Census figures for whites. RESULTS: In 1990-2000 the adjusted annual incidence rates for UC and CD were 8.8 cases per 100,000 (95% confidence interval [CI], 7.2-10.5) and 7.9 per 100,000 (95% CI, 6.3-9.5), respectively, not significantly different from rates observed in 1970-1979. On January 1, 2001, there were 220 residents with CD, for an adjusted prevalence of 174 per 100,000 (95% CI, 151-197), and 269 residents with UC, for an adjusted prevalence of 214 per 100,000 (95% CI, 188-240). CONCLUSION: Although incidence rates of CD and UC increased after 1940, they have remained stable over the past 30 years. Since 1991 the prevalence of UC decreased by 7%, and the prevalence of CD increased about 31%. Extrapolating these figures to US Census data, there were approximately 1.1 million people with inflammatory bowel disease in the US in 2000.

Symptomatic overlap between irritable bowel syndrome and microscopic colitis.

BACKGROUND: Microscopic colitis is diagnosed on the basis of histologic criteria, and irritable bowel syndrome (IBS) is diagnosed by symptom-based criteria. There has been little investigation into the symptomatic overlap between these conditions. Our aim was to assess the prevalence of symptoms of irritable bowel syndrome in a population-based cohort of patients with microscopic colitis. METHODS: The Rochester Epidemiology Project (REP), a medical records linkage system providing all health care data for the defined population of Olmsted County, Minnesota, was used to identify all county residents with a diagnosis of microscopic colitis between 1985 and 2001. The medical records of these individuals were reviewed to ascertain symptoms consistent with Rome, Rome II, and Manning criteria for irritable bowel syndrome. RESULTS: One hundred thirty-one cases of microscopic colitis were identified. Median age at diagnosis was 68 years (range, 24-95); 71% were women. Sixty-nine (53%) and 73 (56%) met Rome and Rome II criteria for irritable bowel syndrome, respectively. Fifty-four (41%) had three or more Manning criteria. Forty-three (33%) had previously been diagnosed with irritable bowel syndrome. CONCLUSIONS: In this population-based cohort of histologically confirmed microscopic colitis, approximately one-half met symptom-based criteria for the diagnosis of irritable bowel syndrome. The clinical symptom-based criteria for irritable bowel syndrome are not specific enough to rule out the diagnosis of microscopic colitis. Therefore, patients with suspected diarrhea-predominant irritable bowel syndrome should undergo biopsies of the colon to investigate for possible microscopic colitis if symptoms are not well controlled by antidiarrheal therapy.

The epidemiology of microscopic colitis: a population based study in Olmsted County, Minnesota.

OBJECTIVE: Although the epidemiology of microscopic colitis has been described in Europe, no such data exist from North America. We studied the incidence, prevalence and temporal trends of microscopic colitis in a geographically defined US population. DESIGN AND SETTING: In this population based cohort study, residents of Olmsted County, Minnesota, with a new diagnosis of microscopic colitis, and all who had colon biopsies for evaluation of diarrhoea, between 1 January 1985 and 31 December 2001 were identified. Biopsies were reviewed for confirmation (cases) and to identify missed cases (diarrhoea biopsies). MAIN OUTCOME MEASURES: Incidence rates, age and sex adjusted to the 2000 US white population. Poisson regression assessed the association of calendar period, age and sex with incidence. RESULTS: We identified 130 incident cases for an overall rate of 8.6 cases per 100,000 person-years. There was a significant secular trend, with incidence increasing from 1.1 per 100,000 early in the study to 19.6 per 100,000 by the end (p<0.001). Rates increased with age (p<0.001). By subtype, the incidence was 3.1 per 100,000 for collagenous colitis and 5.5 per 100,000 for lymphocytic colitis. Collagenous colitis was associated with female sex (p<0.001) but lymphocytic colitis was not. Prevalence (per 100,000 persons) on 31 December 2001 was 103.0 (39.3 for collagenous colitis and 63.7 for lymphocytic colitis). CONCLUSIONS: The incidence of microscopic colitis has increased significantly over time, and by the end of the study, the incidence and prevalence were significantly higher than reported previously. Microscopic colitis is associated with older age, and collagenous colitis is associated with female sex.

Abnormal hepatic biochemistries in patients with inflammatory bowel disease.

OBJECTIVES: The relationship between abnormal hepatic biochemistries and inflammatory bowel disease (IBD) is unclear. We determined the prevalence of abnormal hepatic biochemistries and chronic liver disease in a cohort of IBD patients, and we compared patients with normal and abnormal liver biochemistries. METHODS: Patients with IBD evaluated at our institution between January 1, 2000 and December 31, 2000 were identified. Data on gender, age, IBD subtype, extent and activity, medications, liver disease history, liver biochemistries, and vital status were collected. The chi(2) test, Student's t-test, and Cox proportional regression were used. RESULTS: We identified 544 patients with available hepatic biochemistries. Abnormal hepatic biochemistries were found in 159 (29%). Defined chronic liver disease was present in 5.8% of patients (primary sclerosing cholangitis in 4.6%). The prevalence of abnormal hepatic biochemistries was 27% for those with active IBD and 36% for those in remission (P= 0.06). Patients with abnormal hepatic biochemistries were less frequently on 5-aminosalicylates (35%vs 51%, P < 0.001), and a smaller proportion was alive at last follow-up (90.4%vs 98.5%, P < 0.0001). The age-adjusted risk of death was 4.8 times higher in patients with abnormal hepatic biochemistries, after excluding patients with any diagnosis of liver disease. CONCLUSIONS: Abnormal hepatic biochemistries were present in nearly one-third of our patients, and surprisingly, they were not associated with IBD activity. Abnormal hepatic biochemistries and chronic liver disease appeared to have a negative impact on vital status. Persistently abnormal hepatic biochemistries should be evaluated, and not attributed to IBD activity.

Active Crohn disease: CT findings and interobserver agreement for enteric phase CT enterography.

PURPOSE: To retrospectively evaluate small-bowel enhancement characteristics and the sensitivity, specificity, and interobserver agreement of computed tomographic (CT) findings by using histologic and endoscopic results as a reference standard in patients undergoing enteric phase CT enterography. MATERIALS AND METHODS: The institutional review board approved this retrospective HIPAA-compliant study, which included patients who consented to having their medical records used for research purposes. Enteric phase CT enterographic and ileoscopic findings with or without ileal histologic results were examined in 42 patients (24 women, 18 men). Enteric phase CT enterography was performed after 150 mL of intravenous contrast material was administered at 4 mL/sec, with a 45-second delay. Mural attenuation was measured in the distended and collapsed jejunal and ileal loops and in the terminal ileum. Two radiologists examined CT images for findings of Crohn disease. Mural attenuation for different bowel loops was compared by using a Student t test, with kappa statistics used to measure interobserver agreement and Pearson correleation coefficients used to compare visual and quantitative measures. RESULTS: Distended jejunal loops had significantly greater attenuation than distended ileal loops (113 HU vs 72 HU; P < .001). Attenuation of collapsed jejunal (134 HU) and ileal (108 HU) loops was greater than that of distended jejunal and ileal loops (P < .001). Terminal ileal enhancement was the most sensitive visual CT finding of Crohn disease for both radiologists. Mural thickening demonstrated the greatest interobserver agreement (kappa = 0.83). Visual enhancement and quantitative mural attenuation were significantly correlated (P < .003). CONCLUSION: At enteric phase CT enterography, jejunal attenuation is greater than ileal attenuation and collapsed bowel loops demonstrate greater attenuation than distended bowel loops. Mural hyperenhancement and increased mural thickness are the most sensitive CT findings of active Crohn disease.

Prevention of colorectal cancer in inflammatory bowel disease: value of screening and 5-aminosalicylates.

Colorectal cancer is a serious complication of inflammatory bowel disease. Given this fact, it is necessary to examine the opportunities for current and future approaches to colorectal cancer prevention. The value of surveillance colonoscopy and chemoprevention of colorectal cancer with 5'-aminosalicylic acid has been evaluated in the recent literature. The current state of knowledge in the epidemiology of and new approaches to the prevention of cancer and dysplasia in inflammatory bowel disease were reviewed. It is concluded that there is significant preclinical and clinical evidence to suggest that 5-aminosalicylate drugs reduce the risk of colorectal neoplasia. However, the minimal dosage to achieve this chemopreventive effect remains unclear. There is also indirect evidence to suggest that surveillance colonoscopy is beneficial for patients with inflammatory bowel disease, particularly in those with long-standing pancolitis or primary sclerosing cholangitis-associated inflammatory bowel disease. However, definitive proof from prospective clinical trials is not available.

Evolving diagnostic strategies for inflammatory bowel disease.

Advances in serologic markers, endoscopy, and radiology have led to rapid expansion of diagnosis and disease activity assessment of inflammatory bowel disease (IBD). Serologic markers may have diagnostic value in patients with an intermediate pretest probability of IBD, but these serology tests lack complete sensitivity, and a negative serology result does not exclude the possibility of IBD. Several recent studies have confirmed the utility of serologies in predicting intestinal complications and need for surgery in Crohn's disease. Serum C-reactive protein concentrations correlate with clinical, endoscopic, and radiologic measures of disease activity and appear to have prognostic value in acute severe colitis. Capsule and double balloon endoscopy allow visual inspection of previously inaccessible areas of the small intestine and are useful for patients with suspected small bowel involvement but negative results on conventional testing. CT enterography, which entails oral ingestion of a large volume of a neutral or negative contrast agent and scanning that highlights differences in contrast between the lumen and the bowel wall, appears to be more sensitive than small bowel follow-through for detecting small bowel Crohn's disease and provides extraluminal information. Magnetic resonance enterography uses principles similar to those for CT enterography, and early results are encouraging.

Colorectal cancer prognosis among patients with inflammatory bowel disease.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is associated with an increased risk for colorectal cancer (CRC). However, the genetic, endoscopic, and histologic features of IBD-associated CRC differ from cancers that arise sporadically. The objectives of this study were to describe the clinicopathologic features of IBD-associated CRC and to compare survival rates between patients with IBD-associated CRC and patients with sporadic CRC. METHODS: There were 290 patients with IBD-associated CRC (241 with chronic ulcerative colitis [CUC] and 49 with Crohn's disease) and an equal number of age- and sex-matched sporadic CRC patients who were evaluated at the Mayo Clinic between 1976 and 1996. Medical records were reviewed retrospectively for demographic features, endoscopic and histologic characteristics, and vital status at the time of the last follow-up evaluation. The actuarial survival of each group was calculated by the Kaplan-Meier method. The influence of clinical features on survival was assessed using Cox proportional hazards regression modeling. RESULTS: The median age at diagnosis of IBD-related CRC was 48 years. Fifty-five percent of IBD-related tumors were distal to the splenic flexure compared with 78% of sporadic tumors. During a median follow-up period of 5 years, 163 IBD-associated CRC patients died (56%), compared with 164 sporadic CRC patients (57%). The 5-year survival rates were 54% in the IBD-CRC subgroup vs 53% in the sporadic CRC subgroup (P = .94, log-rank). CONCLUSIONS: CUC-related CRC is diagnosed at a relatively young age, and IBD-related tumors tend to be distributed more evenly across the colorectum than sporadic tumors. The survival rates for IBD-associated and sporadic CRC were similar.

Epidemiology and risk factors for colorectal dysplasia and cancer in ulcerative colitis.

Patients with UC are at increased risk of CRC, but a series of population-based studies published within the past 5 years suggest that this risk has decreased over time. The crude annual incidence rate of CRC in UC ranges from approximately 1 in 500 to 1 in 1600. In some cohorts, an elevated risk of CRC relative to the general population can no longer be demonstrated. The exact mechanism for this decrease in risk remains unclear but may be attributable to a combination of more widespread use of maintenance therapy and surveillance colonoscopy as well as more judicious reliance on colectomy. In addition to the classic risk factors of increased extent and duration of UC, it seems that PSC, a family history of sporadic CRC, severity of histologic bowel inflammation, and young age at colitis onset are independent risk factors for cancer.

Safety of infliximab and other biologic agents in the inflammatory bowel diseases.

In many ways, infliximab has drastically altered expectations for medical therapy in IBD, and it is expected that adalimumab and certolizumab pegol with ultimately have a similar role. Patients initiating such therapy should be made cognizant of the potential risks of serious infection including opportunistic ones, such as TB and histoplasmosis; demyelinating disorders; CHF; and lymphoma. Proper selection of candidates for anti-TNF-alpha therapy is critical in maintaining a proper benefit-to-risk ratio.

Risk of intestinal cancer in inflammatory bowel disease: a population-based study from olmsted county, Minnesota.

BACKGROUND & AIMS: The risk for colorectal cancer in Crohn's disease and ulcerative colitis patients from the United States currently is unknown. We estimated the risk for small-bowel and colorectal cancer in a population-based cohort of 692 inflammatory bowel disease patients from Olmsted County, Minnesota, from 1940 to 2001. METHODS: The Rochester Epidemiology Project was used to identify cohort patients with colorectal and small-bowel cancer. The cumulative probability of cancer and standardized incidence ratios (SIR) were estimated using expected rates from Surveillance, Epidemiology, and End Results, white patients from Iowa, from 1973 to 2000, and Olmsted County, from 1980 to 1999. RESULTS: Colorectal cancer was observed in 6 ulcerative colitis patients vs 5.38 expected (SIR, 1.1; 95% confidence interval [CI], 0.4-2.4), but 4 of these occurred among those with extensive colitis or pancolitis (SIR, 2.4; 95% CI, 0.6-6.0). Six Crohn's disease patients (vs 3.2 expected) developed colorectal cancer (SIR, 1.9; 95% CI, 0.7-4.1). Three Crohn's disease patients developed small-bowel cancer vs 0.07 expected (SIR, 40.6; 95% CI, 8.4-118). CONCLUSIONS: The risk for colorectal cancer was not increased among ulcerative colitis patients overall, but appeared to be increased among those with extensive colitis. The colorectal cancer risk was increased slightly among Crohn's disease patients, who also had a 40-fold excess risk for small-bowel cancer.

Predictive and protective factors associated with colorectal cancer in ulcerative colitis: A case-control study.

BACKGROUND & AIMS: Predictive and protective factors associated with colorectal cancer in chronic ulcerative colitis are not well described. Surveillance colonoscopy and 5-aminosalicylic acid therapy may mitigate cancer risk, but there is debate because these variables have not been evaluated in the same study. The presence of postinflammatory pseudopolyps and use of other anti-inflammatory medications may be important variables that influence risk, but data are sparse. METHODS: Variables associated with colorectal cancer were registered in 188 patients with ulcerative colitis-related cancer and matched controls. Conditional logistic regression, adjusted for age at colitis diagnosis and colitis duration, identified a final set of variables independently associated with colorectal cancer. RESULTS: In the final multiple variable model, the most important factors associated with colorectal cancer were a history of pseudopolyps (OR, 2.5; 95% CI: 1.4-4.6), 1 or 2 surveillance colonoscopies (OR, 0.4; 95% CI: 0.2-0.7), smoking (OR, 0.5; 95% CI: 0.2-0.9) and use of corticosteroids (OR, 0.4; 95% CI: 0.2-0.8), aspirin (OR, 0.3; 95% CI: 0.1-0.8), nonsteroidal anti-inflammatory drugs (OR, 0.1; 95% CI: 0.03-0.5), and 5-aminosalicylic acid agents (OR, 0.4; 95% CI: 0.2-0.9), although the latter was not statistically significant after 5 years. Primary sclerosing cholangitis and immunosuppressive use were not statistically significant. CONCLUSIONS: These results suggest that, in a population matched for extent and duration of chronic ulcerative colitis, surveillance colonoscopy and use of anti-inflammatory medications may reduce the risk of colorectal cancer. A history of postinflammatory pseudopolyps appears to be a predictive factor for cancer.

Incidence and prognosis of colorectal dysplasia in inflammatory bowel disease: a population-based study from Olmsted County, Minnesota.

BACKGROUND AND AIMS: The risk, fate, and ideal management of colorectal dysplasia in inflammatory bowel disease (IBD) remain debated. We estimated the incidence, long-term outcome, and risk factors for progression of colorectal dysplasia (adenomas [adenoma-associated lesions or masses (ALMs)], flat dysplasia, and dysplasia-associated lesions or masses [DALMs]) in a population-based IBD cohort from Olmsted County, Minnesota. MATERIALS AND METHODS: The Rochester Epidemiology Project was used to identify cohort patients with colorectal dysplasia. Medical records were reviewed for demographic and clinical characteristics. Histology slides were reviewed by a pathologist blinded to previous pathology reports. The cumulative incidence of dysplasia was estimated, and the association between patient characteristics and recurrence/progression of dysplasia was assessed using proportional hazards regression. RESULTS: Twenty-nine (4%) IBD patients developed flat dysplasia (n = 8), DALMs (n = 1), ALMs in areas of IBD (n = 18), or ALMs outside areas of IBD (n = 2). Among 6 patients with flat low-grade dysplasia (fLGD) who did not undergo colectomy, none progressed during a median of 17.8 (range 6-21) years of observation with a median of 3 (range 0-12) surveillance colonoscopies. Four (22%) patients with ALMs in areas of IBD who did not undergo surgery developed LGD or DALMs. Primary sclerosing cholangitis and dysplasia located proximal to the splenic flexure were significantly associated with risk for recurrence/progression of dysplasia. CONCLUSIONS: This population-based cohort study from Olmsted County, Minnesota did not confirm an increased risk of cancer related to fLGD, whereas 22% of patients with ALMs in areas of IBD developed fLGD or DALMs.

Microscopic colitis is not associated with cholecystectomy or appendectomy.

BACKGROUND: Microscopic colitis is a common cause of chronic watery diarrhea of unknown origin. Some patients develop diarrhea after cholecystectomy, and some patients with microscopic colitis have evidence of bile acid malabsorption. However, the association between cholecystectomy and microscopic colitis has not been studied. A protective effect of appendectomy on the development of ulcerative colitis also has been reported, but its relationship with microscopic colitis has not been studied. The aim of this study was to assess cholecystectomy and appendectomy as potential risk factors for the development of microscopic colitis in a nested case-control study. MATERIALS AND METHODS: Using the Rochester Epidemiology Project, we identified all Olmsted County (Minnesota) residents with an initial diagnosis of microscopic colitis between January 1, 1985, and December 31, 2001. Rates of antecedent cholecystectomy or appendectomy in patients with microscopic colitis were compared with age-, gender-, and calendar year-matched community controls through conditional logistic regression. RESULTS: Microscopic colitis was identified in 130 cases. Cholecystectomy preceded the diagnosis of microscopic colitis in 12 cases (9%) compared with 17 (13%) in the control group (odds ratio [OR] 0.7; 95% CI 0.3-1.5). Appendectomy preceded the diagnosis of microscopic colitis in 39 subjects (30%) compared with 28 (22%) in the control group (OR 1.6; 95% CI 0.9-2.7). Similar results were obtained when the analysis was restricted to microscopic colitis subtype (lymphocytic colitis or collagenous colitis). CONCLUSIONS: In this population-based nested case-control study, no significant association was seen between cholecystectomy or appendectomy and the development of microscopic colitis or its subtypes.

Budesonide in the treatment of inflammatory bowel disease: the first year of experience in clinical practice.

BACKGROUND: Delayed release budesonide was approved by the FDA for the treatment of mildly to moderately active Crohn's disease involving the ileum and ascending colon. Controlled trials have demonstrated that budesonide is effective in inducing remission and for maintenance of remission, with less frequent steroid side effects than conventional steroids. We sought to determine the benefit of this medication in clinical practice and to identify any non-FDA-approved uses that may warrant further study. METHODS: Patients in whom oral budesonide was prescribed between November 1, 2001 and October 31, 2002, were identified and medical records were reviewed. Patients were categorized by indication for therapy: ileocolonic Crohn's disease (group 1), Crohn's disease elsewhere (group 2), and other conditions (group 3). RESULTS: A total of 225 patients were identified (108 in group 1, 62 in group 2, and 55 in group 3). Group 3 included patients with microscopic colitis (n = 28), pouchitis (n = 13), ulcerative colitis (n = 12), and celiac disease (n = 2). A favorable outcome occurred in 61% of group 1 patients but only 24% of patients in group 2. In group 3, only microscopic colitis patients and pouchitis patients experienced response rates >50% (77% and 60%, respectively). CONCLUSION: Budesonide is effective in a majority of patients with ileocolonic Crohn's disease and microscopic colitis, which is consistent with results reported from clinical trials. A majority of patients with pouchitis also benefit from budesonide therapy, but prospective controlled trials are necessary to clarify the benefit in this group.

Medical management of left-sided ulcerative colitis and ulcerative proctitis: critical evaluation of therapeutic trials.

BACKGROUND: The goal of this work was to critically evaluate the published studies on the treatment of ulcerative proctitis (UP) and left-sided ulcerative colitis (L-UC). The results of this review provided the content for the accompanying treatment guidelines, Clinical Guidelines for the Medical Management of Left-sided Ulcerative Colitis and Ulcerative Proctitis: Summary Statement. METHODS: All English language articles published between 1995 and September 2005 were identified through a comprehensive literature search using OVID and PubMed. The quality of the data supporting or rejecting the use of specific therapies was categorized by a data quality grading scale. An "A+" grade was assigned to treatment supported by multiple high-quality randomized controlled trials with consistent results, whereas a "D" grade was given to therapy supported only by expert opinion. The therapeutic efficacy of a treatment was defined by its success in treating UP and L-UC compared with placebo. A medication was ranked as "excellent" if it was specifically studied for UP and L-UC and had consistently positive results compared with placebo or another agent. Quality and efficacy scores were agreed on by author consensus. RESULTS: For the acute treatment of UP or L-UC, the rectally administered corticosteroids and mesalazine (5-ASA), either alone or in combination with oral 5-ASAs, are the most effective therapy: evidence quality, A+; efficacy, excellent. Only rectally administered 5-ASA received an A+/excellent rating for maintenance of remission. Infliximab received an A+ grade for induction and maintenance of remission but only a "good" rating because the studies were performed in all UC, not specifically UP or L-UC. CONCLUSIONS: This critical evaluation of treatment provides a "report card" on medications available for the management of patients with UP and L-UC. The guidelines should provide a useful reference and supplement for physicians treating UC patients.

Clinical guidelines for the medical management of left-sided ulcerative colitis and ulcerative proctitis: summary statement.

There are few published guidelines for the treatment of inflammatory bowel disease. Physicians choose therapy based on evidence-based data, peer and expert opinion, and personal experience. This article provides treatment guidelines for the induction and maintenance of ulcerative proctitis and left-sided colitis and the management of disease refractory to 5-aminosalicylic acid (5-ASA) compounds and corticosteroids The guidelines are derived from evidence-based data and, when lacking, expert opinion or the authors' experience. The comprehensive review of the literature is presented in the accompanying article, "The Medical Management of Left-Sided Ulcerative Colitis and Ulcerative Proctitis: Critical Evaluation of Therapeutic Trials". Rectally administered 5-ASA and corticosteroid suppositories are effective treatment for most ulcerative proctitis patients. Corticosteroid and 5-ASA enemas, which reach the splenic flexure of the colon, are recommended for patients with left-sided ulcerative colitis. The combination of rectally administered 5-ASA enemas and oral 5-ASA agents may afford better treatment of left-sided colitis and possibly prevent proximal extension of disease. Patients refractory to 5-ASAs and corticosteroids may require an immunomodulator or biological response modifier therapy. Those who have ongoing signs and symptoms of ulcerative proctitis and left-sided ulcerative colitis despite maximal medical therapy require a proctocolectomy.
