Abstract
PURPOSE Patients with inflammatory bowel disease (IBD) often experience severe impairment in different life domains. Psychological factors, such as illness perceptions and coping, may play a role in the adjustment to IBD as indicated by mental and physical health, activity, and work impairment. The present study aimed at examining the assumption of the Common Sense Model (CSM) that coping mediates the relationship between illness perceptions and adjustment in patients with IBD. METHOD In a cross-sectional design, 211 IBD patients (73 % Crohn's disease, 40 % male, mean age 42.9 ± 12.9 years) attending an outpatient clinic completed questionnaires assessing illness perceptions (IPQ-R), coping (CORS), mental and physical health (SF-36), as well as activity and work impairment (WPAI). Multiple mediation analyses were applied that allow estimating the total and direct effects of all illness perception dimensions and the indirect effects through all coping strategies on the illness outcomes simultaneously. RESULTS The analyses yielded significant direct effects of perceptions regarding the cyclical course, the chronic course, the severity of the consequences, the comprehensibility, and the emotional impact of IBD on study outcomes. Additionally, significant indirect effects were found for the perceptions regarding the severity of the consequences, the possibility of personal control, and the comprehensibility of IBD on mental and physical health as well as activity impairment through the use of one specific coping strategy, i.e., reduction of activity. CONCLUSION The results provide evidence for the assumptions of the CSM and suggest the importance of addressing illness perceptions and activity stimulation in quality health care for IBD patients.

Abstract
INTRODUCTION Autologous hematopoietic stem cells are gaining ground as an effective and safe treatment for treating severe refractory Crohn's disease (CD). Autologous hematopoietic stem cell therapy (AHSCT) induces resetting of the immune system by de novo regeneration of T-cell repertoire and repopulation of epithelial cells by bone-marrow derived cells to help patients achieve clinical and endoscopic remission. Areas covered: Herein, the authors discuss the use of AHSCT in treating patients with CD. Improvements in disease activity have been seen in patients with severe autoimmune disease and patients with severe CD who underwent AHSCT for a concomitant malignant hematological disease. Clinical and endoscopic remission has been achieved in patients treated with AHSCT for CD. The only randomized trial published to date, the ASTIC Trial, did not support further use of AHSCT to treat CD. Yet, critics of this trial have deemed AHSCT as a promising treatment for severe refractory CD. Expert opinion: Even with the promising evidence presented for HSCT for refractory CD, protocols need to be refined through the collaboration of GI and hemato-oncology professionals. The goal is to incorporate safe AHSCT and restore tolerance by delivering an effective immune 'cease fire' as a treatment option for severe refractory CD.

Abstract
BACKGROUND AND AIMS Peripheral joint complaints [pJTC] and chronic back pain [CBP] are the most common extra-intestinal manifestations in patients with inflammatory bowel disease [IBD]. This prospective study evaluates variables associated with joint/back pain, including IBD disease activity. METHODS IBD patients with back pain ≥ 3 months and/or peripheral joint pain/swelling [n = 155], and IBD patients without joint complaints [n = 100; controls], were followed for a period of 1 year. Patients were classified as having SpondyloArthritis [SpA] according to several sets of criteria. Statistical analysis included logistic regression models and linear mixed model analysis. RESULTS Of the 155 patients with joint/back pain, 13 had chronic back pain, 80 peripheral joint complaints, and 62 axial and peripheral joint complaints. Smoking, female gender, and IBD disease activity were independently associated with IBD joint/back pain. The Assessment in Spondyloarthritis International Society criteria for axial and peripheral SpA were fulfilled in 12.3% of patients, with 9.7% [n = 15] receiving a rheumatological diagnosis of arthritis. During the 12-month follow-up, the majority of the patients reporting joint/back pain remained stable. CONCLUSIONS In our cohort, the majority of IBD patients reported joint/back pain and SpA was relatively common. To facilitate effective care, gastroenterologists should be aware of the various features of SpA to classify joint complaints and, by making use of an efficient referral algorithm, to refer CBP patients to the rheumatologist.

Abstract
OBJECTIVES To assess whether subclinical inflammatory changes are present on magnetic resonance imaging (MRI) in patients with inflammatory bowel disease (IBD) and arthralgia. METHOD In this pilot study, painful hand joints [metacarpophalangeal (MCP), proximal interphalangeal (PIP), and/or distal interphalangeal (DIP)] of 11 IBD patients (age 18-45 years) with continuous pain for > 6 weeks were scanned on a 1.5-T extremity MRI system. A control group of 11 IBD patients without joint pain who were matched for type and disease duration of IBD, gender, and age was included. All patients were clinically examined by a rheumatologist for the presence of pain and arthritis. Imaging was performed according to a standard arthritis protocol with intravenous contrast administration on the same day. Images (blinded for clinical information) were evaluated by two readers in consensus for the presence of joint fluid, synovitis, tenosynovitis, enthesitis, erosions, cartilage defects, and bone marrow oedema. RESULTS Enthesitis was seen in three hand joints (MCP 2, MCP 3, PIP 3) of 2/11 (18%) arthralgia patients and in none of the control group (p = 0.48). A small amount of subchondral bone marrow oedema was seen in the metacarpal head of two controls. No other abnormalities were observed. CONCLUSIONS Several young IBD patients with chronic hand pain had subclinical inflammation on MRI, which invites for further study in a larger group of patients.

Abstract
BACKGROUND The impact of pregnancy on the course of IBD is still controversial. AIM To investigate the impact of pregnancy on IBD and to search for factors with potential impact on remission. METHODS Pregnant IBD women from 12 European countries were enrolled between January 2003 and December 2006 and compared at conception (1:1) with nonpregnant IBD women. Data on disease course were prospectively collected at each trimester during pregnancy and in the postpartum (6 months) using a standardised questionnaire. RESULTS A total of 209 pregnant IBD women were included: 92 with Crohn's disease (CD; median age 31 years, range 17-40) and 117 with ulcerative colitis (UC; median age 32 years, range 19-42). No statistically significant difference in disease course during pregnancy and postpartum was observed between pregnant and nonpregnant CD women. Longer disease duration in CD and immunosuppressive therapy were found to be risk factors for activity during pregnancy. Pregnant UC women were more likely than nonpregnant UC women to relapse both during pregnancy (RR 2.19; 95% CI: 1.25-3.97, 0.004) and postpartum (RR 6.22; 95% CI: 2.05-79.3, P = 0.0004). During pregnancy, relapse was mainly observed in the first (RR 8.80; 95% CI 2.05-79.3, P < 0.0004) and the second trimester (RR 2.84, 95% CI 1.2-7.45, P = 0.0098). CONCLUSIONS Pregnant women with Crohn's disease had a similar disease course both during pregnancy and after delivery as the nonpregnant women. In contrast, pregnant women with ulcerative colitis were at higher risk of relapse during pregnancy and in the postpartum than nonpregnant ulcerative colitis women.

Abstract
BACKGROUND AND AIMS We examined the impact of disease duration on clinical outcomes and safety in a post hoc analysis of a remission maintenance trial with adalimumab in patients with moderate to severe CD. METHODS Patients in the CHARM trial were divided into 3 disease duration categories: <2 (n=93), 2 to <5 (n=148), and ≥5 years (n=536). Clinical remission and response rates at weeks 26 and 56 were compared between adalimumab and placebo subgroups, and assessed through 3 years of adalimumab treatment in the ADHERE follow-on trial. Logistic regression assessed the effect of disease duration and other factors on remission and safety. RESULTS At week 56, clinical remission rates were significantly greater for adalimumab-treated versus placebo-treated patients in all 3 duration subgroups (19% versus 43% for <2 years; P=0.024; 13% versus 30% for 2 to <5 years; P=0.028; 8% versus 28% for ≥5 years, P<0.001). Logistic regression identified shorter duration as a significant predictor for higher remission rate in adalimumab-treated patients. Patients with disease duration <2 years maintained higher remission rates than patients with longer disease duration through 3 years of treatment. The incidence of serious adverse events in adalimumab-treated patients was lowest with disease duration <2 years. CONCLUSIONS Adalimumab was superior to placebo for maintaining clinical remission in patients with moderately to severely active CD after 1 year of treatment regardless of disease duration. Clinical remission rates through 3 years of treatment were highest in the shortest disease duration subgroup in adalimumab-treated patients, with a trend to fewer side effects.

Abstract
BACKGROUND Immune suppressant medications such as thiopurines and anti-tumor necrosis factor agents are important for maintaining disease control in most patients with inflammatory bowel diseases (IBDs); however, their use has been associated with the development of malignant lymphoma. The purpose of this Dutch nationwide study was to estimate the relative risk of malignant lymphoma in IBD patients. METHODS IBD patients who developed a lymphoma between 1997 and 2004 were identified using the Dutch National Database of PALGA. Data from confirmed cases were collected from individual hospitals, including data on Epstein-Barr virus (EBV). The age-adjusted 8-year incidence of malignant lymphoma in the Netherlands was retrieved from the Central Bureau of Statistics. RESULTS Forty-two hospitals were visited and 285 matches evaluated in the total cohort of 17,834 IBD patients. Forty-four lymphomas were observed, resulting in a relative risk of 1.27 (95% confidence interval [CI]: 0.92-1.68). Only 19 of 44 patients (43%) were exposed to azathioprine/6-mercaptopurine (AZA/6-MP). Remarkably, 92% of patients (11/12) with EBV-positive lymphoma used AZA/6-MP, in contrast to only 19% patients (4/21) with EBV-negative lymphoma, suggesting a strong relation between EBV-positive lymphoma and thiopurine use. CONCLUSIONS This nationwide study does not suggest a significant overall increased risk for lymphoma in IBD patients. A distinct correlation between EBV-positive lymphoma and AZA/6-MP use was observed.

Abstract
The natural course of Crohn's disease is characterized by the progression from primarily inflammatory disease to a complicated stricturing or penetrating disease. This irreversible complications lead to repeated surgery and considerable disability. It may therefore be argued that a window of opportunity for intensive treatment exists early in the disease course. Healing of the mucosa has been shown to be a strong predictor of improved outcome of Crohn's disease on the long-term, in terms disease control, hospitalizations, and surgery. Anti-tumor necrosis factor (TNF)-alpha therapy has shown to be a strong inducer of mucosal healing and it may be argued that early treatment with anti-TNF's and/or immunomodulators may be the preferable approach in selected patients. The main concern with such strategies is safety, especially the risk of lymphoma's and infections. This paper aims to review the existing data regarding the benefits and disadvantages of inverting the classic step up therapeutic paradigm.

Abstract
OBJECTIVE In acromegaly, overproduction of GH and IGF-I causes abnormal extracellular matrix regulation. We hypothesized that this may predispose to the development of colonic diverticula. Because the relation between acromegaly and colonic diverticula is unknown, the study aim was to assess the prevalence of colonic diverticula in patients with cured acromegaly. DESIGN This was a case-control study. METHODS We screened reports of colonoscopies performed for the purpose of screening for polyps in 107 patients with cured or biochemically controlled acromegaly and in 214 age- and sex-matched controls for the presence of diverticula, dolichocolon, and polyps. In patients, the findings were related to GH/IGF-I concentrations at the time of diagnosis of acromegaly and to the duration of GH/IGF-I excess. RESULTS In acromegaly, colonic diverticula were present in 37% of patients, dolichocolon in 34%, and adenomatous polyps in 34%, which was increased compared with controls (odds ratio 3.6, 95% confidence interval 1.4, 5.7; 12.4, 95% confidence interval 6.8, 18.0; 4.1, 95% confidence interval 1.9, 6.4, respectively). The presence of colonic diverticula was associated with both GH and IGF-I concentrations at the time of diagnosis of acromegaly, when adjusted for the duration of active disease. The presence of dolichocolon and adenomatous polyps was associated with higher IGF-I concentrations at diagnosis. CONCLUSIONS Acromegaly is associated with an increased prevalence of colonic diverticula. In addition to the known irreversible effect of GH excess on collagen of joints and cardiac valves, this observation indicates an irreversible effect of GH and/or IGF-I on the collagen in the colon.

Abstract
OBJECTIVE The aim of the study was to evaluate the impact of the genomic deletion of exon 3 of the GH receptor (d3GHR) on long-term clinical outcome of acromegaly in a well-characterized cohort of patients with long-term remission of acromegaly. DESIGN We conducted a cross-sectional study. METHODS The presence of the d3GHR polymorphism was assessed in 86 acromegalic patients with long-term disease control and related to anthropometric parameters, cardiovascular risk factors, osteoarthritis, bone mineral density, colonic polyps and diverticulae, and dolichocolon. RESULTS Fifty-one patients had two wild-type alleles (59%), whereas 29 patients (34%) had one allele and six patients (7%) had two alleles encoding for the d3GHR isoform. Carriers of the d3GHR isoform showed increased prevalence of osteoarthritis, especially of the hip [adjusted odds ratio (OR), 5.2; 95% confidence interval (CI), 3.2-7.1], of adenomatous polyps (adjusted OR, 4.1; 95% CI, 2.4-5.6), and dolichocolon (adjusted OR, 3.2; 95% CI, 1.8-4.6). Anthropometric parameters, cardiovascular risk factors, bone mineral density, and (non)vertebral fractures were not significantly different between patients with and without the d3GHR allele. CONCLUSION In patients with long-term cured acromegaly, the d3GHR polymorphism is associated with an increased prevalence of irreversible comorbidities such as osteoarthritis, dolichocolon, and adenomatous colonic polyps, but not with other comorbidities such as cardiovascular risk factors.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) and concurrent primary sclerosing cholangitis (PSC) have a higher risk of developing colorectal cancer (CRC) than IBD patients without PSC. The aim of this study was to investigate potential clinical differences between patients with CRC in IBD and those with CRC in IBD and PSC, as this may lead to improved knowledge of underlying pathophysiological mechanisms of CRC development. METHODS The retrospective study from 1980-2006 involved 7 Dutch university medical centers. Clinical data were retrieved from cases identified using the national pathology database (PALGA). RESULTS In total, 27 IBD-CRC patients with PSC (70% male) and 127 IBD-CRC patients without PSC (59% male) were included. CRC-related mortality was not different between groups (30% versus 19%, P = 0.32); however, survival for cases with PSC after diagnosing CRC was lower (5-year survival: 40% versus 75% P = 0.001). Right-sided tumors were more prevalent in the PSC group (67% versus 36%, P = 0.006); adjusted for age, sex, and extent of IBD, this difference remained significant (odds ratio: 4.8, 95% confidence interval [CI] 2.0-11.8). In addition, tumors in individuals with PSC were significantly more advanced. CONCLUSIONS The right colon is the predilection site for development of colonic malignancies in patients with PSC and IBD. When such patients are diagnosed with cancer they tend to have more advanced tumors than patients with IBD without concurrent PSC, and the overall prognosis is worse. Furthermore, the higher frequency of right-sided tumors in patients with PSC suggests a different pathogenesis between patients with PSC and IBD and those with IBD alone.

Abstract
BACKGROUND Crohn's disease and ulcerative colitis have a complex genetic background. We assessed the risk for both the development and severity of the disease by combining information from genetic variants associated with inflammatory bowel disease (IBD). METHODS We studied 2804 patients (1684 with Crohn's disease and 1120 with ulcerative colitis) and 1350 controls from seven university hospitals. Details of the phenotype were available for 1600 patients with Crohn's disease and for 800 with ulcerative colitis. Genetic association for disease susceptibility was tested for the nucleotide-binding and oligomerisation domain 2 gene (NOD2), the IBD5 locus, the Drosophila discs large homologue 5 and autophagy-related 16-like 1 genes (DLG5 and ATG16L1) and the interleukin 23 receptor gene (IL23R). Interaction analysis was performed for Crohn's disease using the most associated single nucleotide polymorphism (SNP) for each locus. Odds ratios were calculated in an ordinal regression analysis with the number of risk alleles as an independent variable to analyse disease development and severity. RESULTS Association with Crohn's disease was confirmed for NOD2, IBD5, DLG5, ATG16L1 and IL23R. Patients with Crohn's disease carry more risk alleles than controls (p = 3.85 x 10(-22)). Individuals carrying an increasing number of risk alleles have an increasing risk for Crohn's disease, consistent with an independent effects multiplicative model (trend analysis p = 4.25 x 10(-23)). Patients with Crohn's disease with a more severe disease course, operations or an age of onset below 40 years have more risk alleles compared to non-stricturing, non-penetrating behaviour (p = 0.0008), no operations (p = 0.02) or age of onset above 40 years (p = 0.028). CONCLUSION Crohn's disease is a multigenic disorder. An increase in the number of risk alleles is associated with an increased risk for the development of Crohn's disease and with a more severe disease course. Combining information from the known common risk polymorphisms may enable clinicians to predict the course of Crohn's disease.

Abstract
BACKGROUND AND AIMS To detect precancerous dysplasia or asymptomatic cancer, patients suffering from inflammatory bowel disease often undergo colonoscopic surveillance based on American or British guidelines. It is recommended that surveillance is initiated after 8-10 years of extensive colitis, or after 15-20 years for left-sided disease. These starting points, however, are not based on solid scientific evidence. Our aim was to assess the time interval between onset of inflammatory bowel disease (IBD) and colorectal carcinoma (CRC), and subsequently evaluate how many patients developed cancer before their surveillance was recommended to commence. METHODS A nationwide automated pathology database (PALGA) was consulted to identify patients with IBD-associated colorectal carcinoma in seven university medical centres in The Netherlands between January 1990 and June 2006. Data were collected retrospectively from patient charts. Time intervals between onset of disease and cancer diagnosis were calculated in months. RESULTS 149 patients were identified with confirmed diagnoses of IBD and CRC (ulcerative colitis n = 89/Crohn's disease n = 59/indeterminate colitis n = 1). Taking date of diagnosis as the entry point, 22% of patients developed cancer before the 8 or 15 year starting points of surveillance, and 28% if surveillance was commenced 10 or 20 years after diagnosis for extensive or left-sided disease, respectively. Using onset of symptoms to calculate the time interval, 17-22% of patients would present with cancer prior to the surveillance starting points. CONCLUSIONS These results show that the diagnosis of colorectal cancer is delayed or missed in a substantial number of patients (17-28%) when conducting surveillance strictly according to formal guidelines.

Abstract
The prognostic significance of single-nucleotide polymorphisms (SNPs) and tumour protein levels of MMP-2 and MMP-9 was evaluated in 215 colorectal cancer patients. Single-nucleotide polymorphism MMP-2(-1306T) and high MMP-2 levels were significantly associated with worse survival. Extreme tumour MMP-9 levels were associated with poor prognosis but SNP MMP-9(-1562C>T) was not. Tumour MMP levels were not determined by their SNP genotypes.

Abstract
BACKGROUND We recently developed and validated limited sampling models (LSMs) for cyclosporine monitoring after orthotopic liver transplantation based on individualized population pharmacokinetic models with Bayesian modelling. Aim To evaluate LSM in practice, and to seek optimal balance between benefit and discomfort. METHODS In 30 stable patients, more than 6 months after orthotopic liver transplantation, previously switched from trough- to 2 h post-dose (C2)-monitoring, we switched to 3-monthly LSM 0,1,2,3 h-monitoring. During 18 months we evaluated dose, creatinine clearance, calculated area under the curve, intra-patient pharmacokinetic variability and ability to assess systemic exposure by several previously validated LSMs. RESULTS Within patients, there was variability of cyclosporine-area under the curve with the same dose (CV of 15%). Compared to C2-monitoring, there was no significant difference in dose (P = 0.237), creatinine clearance (P = 0.071) and number of rejections. Some models showed excellent correlation and precision with LSM 0,1,2,3 h comparing area under the curves (0,2 h: r(2) = 0.88; 0,1,3 h: r(2) = 0.91; 0,2,3 h: r(2) = 0.92, all P < 0.001) with no difference in advised dose. CONCLUSIONS The limited sampling model, with only trough- and 2-h sampling, yields excellent accuracy and assesses systemic exposure much better than C2 with less bias and greater precision. Considering the calculated intra-patient variability, more precision is redundant, so LSM 0,2 h seems the optimal way of cyclosporine-monitoring.

Abstract
BACKGROUND Fish oil supplements, which are rich in n-3 fatty acids, may reduce inflammation, decrease the need for anti-inflammatory drugs, and promote normal weight gain in people with ulcerative colitis. OBJECTIVES This review evaluates the efficacy of fish oil for induction of remission in ulcerative colitis using all available randomised controlled trials. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, EMBASE, CINAHL, the database of ongoing trials and the reference lists of all publications of included or excluded trials were searched. SELECTION CRITERIA Randomised controlled trials and quasi-randomised controlled trials with active ulcerative colitis patients who were treated with fish oil. DATA COLLECTION AND ANALYSIS The reviewers performed study selection, assessment of methodological quality by using different approaches: including Cochrane assessment of allocation concealment and Jadad quality assessment score. Data extraction forms were used by the two reviewers to extract the data independently. Authors were contacted for additional information. MAIN RESULTS Six studies were included. Three were of cross-over design and three were of parallel design. No data were pooled for analysis due to differences in outcomes and methodology among the included studies. One small study shows a positive benefit for induction of remission (RR 19.00; 95% CI 1.27 to 284.24). Some of the other included studies show some positive benefits for secondary outcomes. However, these results need to be interpreted with caution due to small study size and poor study quality. AUTHORS' CONCLUSIONS The current data does not allow for a definitive conclusion regarding the efficacy of fish oil. There is no adequate information to make recommendations for clinical practice. More research is required.

Abstract
BACKGROUND AND OBJECTIVE Matrix metalloproteinases are associated with matrix turnover in both physiological and pathological conditions. We postulate an association between aberrant matrix metalloproteinases proteolytic activity and the intestinal tissue destruction, seen in patients with Crohn's disease and/or ulcerative colitis. MATERIALS AND METHODS Surgically resected inflamed and non-inflamed ileum and colon with/without extensive fibrosis from 122 Crohn's disease, 20 ulcerative colitis and 62 control patients were homogenized. Protein levels of matrix metalloproteinases and tissue inhibitor of metalloproteinases were measured by enzyme-linked immunosorbent assays (ELISA), while matrix metalloproteinases and myeloperoxidase activity were measured by specific activity assays. RESULTS Expression of total levels of matrix metalloproteinases-1, -2, -3 and -9 relative to tissue inhibitor of metalloproteinases-1 and -2 was increased in inflamed inflammatory bowel disease compared to non-inflamed inflammatory bowel disease and control intestinal mucosa. Also, net matrix metalloproteinases-1, -2, -3 and -9 activity in inflamed inflammatory bowel disease was increased, with similar expression profiles in Crohn's disease and ulcerative colitis. Within inflamed inflammatory bowel disease, a close correlation of matrix metalloproteinases with myeloperoxidase was observed. The expression of matrix metalloproteinases and tissue inhibitor of metalloproteinases was similar in inflamed Crohn's disease tissue with or without extensive fibrosis and not related to fistulizing disease. CONCLUSIONS We have shown increased net matrix metalloproteinases activity in intestinal inflammatory bowel disease tissue, likely to contribute to the tissue damage and remodelling seen in inflammatory bowel disease.

Abstract
Transforming growth factor-β1 (TGF-β1), a tumour suppressing as well as tumour-promoting cytokine, is stored as an extracellular matrix-bound latent complex. We examined TGF-β1 activation and localisation of TGF-β1 activity in gastric cancer. Gastric tumours showed increased stromal and epithelial total TGF-β1 staining by immunohistochemistry. Active TGF-β1 was present in malignant epithelial cells, but most strongly in smooth muscle actin expressing fibroblasts. Normal gastric mucosa from the same patient showed some staining for total, and little for active TGF-β1. Active TGF-β1 levels were determined by ELISA on tissue homogenates, confirming a strong increase in active TGF-β1 in tumours compared to corresponding normal mucosa. Moreover, high tumour TGF-β1 activity levels were significantly associated with clinical parameters, including worse survival of the patients. Total and active TGF-β1 levels were not correlated, suggesting a specific activation process. Of the different proteases tested, active TGF-β1 levels were only correlated with urokinase activity levels. The correlation with urokinase activity suggests a role for plasmin in TGF-β1 activation in the tumour microenvironment, resulting in transformation of resident fibroblasts to tumour promoting myofibroblasts. In conclusion we have shown localisation and clinical relevance of TGF-β1 activity levels in gastric cancer.

Abstract
Abstract
Background
The aim of this systematic review was to assess the prevalence and site of dysplasia after restorative proctocolectomy (RPC) for ulcerative colitis (UC), and to identify risk factors that could be used in a surveillance programme.
Methods
Medical databases were searched for potentially relevant publications between 1978 and 2006. Studies that dealt with RPC for UC and postoperative surveillance were included. Two researchers independently performed study selection, quality assessment, data extraction and analysis.
Results
Twenty-three observational studies and case series were included, with a total of 2040 patients. The pooled prevalence of confirmed dysplasia in the pouch, anal transitional zone or rectal cuff was 1·13 (range 0–18·75) per cent. The prevalence of high-grade dysplasia, low-grade dysplasia and indefinite for dysplasia was 0·15 (range 0–4·49), 0·98 (range 0–15·62) and 1·23 (range 0–25·28 per cent) respectively. Dysplasia was equally frequent in the pouch and rectal cuff or anal transitional zone. Dysplasia and cancer identified before or at operation seemed to be significant predictors of the development of dysplasia. Pouchitis and duration of follow-up were not of predictive value.
Conclusion
Although based on low-level evidence from uncontrolled studies, the prevalence of dysplasia observed after RPC was remarkable. A surveillance programme that takes into account the risk factors found is therefore advocated.

Abstract
BACKGROUND AND STUDY AIM Patients with longstanding ulcerative colitis are at increased risk of developing colorectal cancer. Colonoscopic surveillance is advised, but the detection of neoplasia by conventional colonoscopy is difficult. The aim of this study was to compare the accuracy of narrow-band imaging (NBI), a new imaging technique, with standard colonoscopy for the detection of neoplasia in patients with longstanding ulcerative colitis. PATIENTS AND METHODS This was a prospective, randomized, crossover study of 42 patients with longstanding ulcerative colitis. All participants underwent NBI and conventional colonoscopy with at least 3 weeks between the procedures. Randomization determined the order of the examinations. Targeted biopsies were taken during both procedures; additional random biopsies were taken at conventional colonoscopy only. The number of patients with neoplasia detected by targeted biopsies was used to assess the sensitivity for each technique. RESULTS With NBI, 52 suspicious lesions were detected in 17 patients, compared with 28 suspicious lesions in 13 patients detected during conventional colonoscopy. Histopathological evaluation of targeted biopsies revealed 11 patients with neoplasia: in four patients the neoplasia was detected by both techniques, in four patients neoplasia was detected only by NBI, and in three patients neoplasia was detected only by conventional colonoscopy ( P = 0.705). Aside from targeted biopsies, 1522 random biopsies were taken. These revealed one additional patient with dysplasia that was not detected by either technique. CONCLUSIONS The sensitivity of the studied first-generation NBI system for the detection of patients with neoplasia seems to be comparable to conventional colonoscopy, although more suspicious lesions were found during NBI. We believe that it is still too early to stop taking additional random biopsies at surveillance colonoscopy in patients with ulcerative colitis.
