RESUMO
BACKGROUND AND AIMS: The long-term course of ulcerative colitis [UC] is difficult to predict. Mortality, colectomy, cancer, and hospitalisation represent hard outcomes of disease. Moreover, knowledge on the risk of relapses and need for potent medication add important information about living with UC. We aimed to evaluate the course and prognosis of UC during the first 20 years after diagnosis, and to identify early prognostic risk factors. METHODS: From 1990 to 1994, a population-based inception cohort of patients with inflammatory bowel disease was enrolled in South-Eastern Norway. A systematic follow-up [FU] was conducted at 1,5, 10, and 20 years after diagnosis. Clinical outcomes were recorded continuously, and possible relationships between early disease characteristics and outcomes were analysed using multiple regression analysis. RESULTS: Among 519 UC patients, 119 died, 60 were lost to FU, and 340 were included in the FU cohort. The 20-year cumulative risk of colectomy was 13.0% (95% confidence interval [CI] [11.4-14.6]). Extensive colitis at diagnosis was independently associated with an increased risk of colectomy compared with proctitis (hazard ratio [HR]â =â 2].8, 95% CI [1.3-6.1]). In contrast, mucosal healing at 1-year FU was independently associated with reduced risk of colectomy [HRâ =â 0.4, 95% CI [0.2-0.8]), and inversely associated with subsequent risk of relapse [adjusted HRâ =â 0.5, 95% CI [0.3-0.7]). CONCLUSIONS: The overall risk of colectomy in our cohort was lower than expected from previous studies, although considerable for patients with extensive colitis at diagnosis. Early mucosal healing was associated with better disease outcomes 20 years after diagnosis.

Objective: The association between ulcerative colitis (UC) and colorectal cancer (CRC) is widely accepted, although attenuated risk has been reported in recent years. Colonoscopic surveillance is recommended with intervals based on established clinical risk factors. Nevertheless, a significant number of patients develop interval cancers, indicating the need of improved individualised assessment. In the present study, we evaluated clinical risk factors associated with CRC during a prescheduled follow-up 20 years after diagnosis, the IBSEN study. Design: A population-based inception cohort of patients diagnosed with inflammatory bowel disease from 1 January 1990 until 31 December 1993, prospectively followed at 1, 5, 10 and 20 years after diagnosis. A total of 517 patients with UC were included; 264 (51 %) men; median age at inclusion 37.4 years (4-88). Results: The overall incidence of CRC was 1.6% (8/517) at a 20-year follow-up. The total lifetime risk of CRC prior to or after UC diagnosis was 2.3%. (12/517). Patients older than 70 years at diagnosis had a 15-fold higher risk of CRC compared with those diagnosed when younger than 40 years, with HR 15.68 (95% CI: 1.31 to 187.92). Neither sex, first-degree relative with CRC, extent of colitis nor primary sclerosing cholangitis affected the risk of CRC. Conclusion: The risk of CRC in UC was low and comparable with the risk of CRC in the background population of Norway.

Background and aims The quality of medical quality registers is poorly defined and lack of trust in data due to low completeness may be a major barrier against their use in quality improvement interventions. The aim of the current observational study was to explore how selective reporting may influence adverse events registered in the Norwegian quality register for colonoscopy (Gastronet). Materials and methods Gastronet's database includes data provided by endoscopists, nurses and patients. All outpatient colonoscopies reported to Gastronet in 2015 were included and compared to the total number of colonoscopies performed in Norway as retrieved from the National Patient Registry. Hospitals were categorized into four groups according to reporting completeness <â50â%, 50â% to 69â%, 70â% to 89â% and ≥â90â%. The number of recorded adverse events (AEs) and procedure time were analyzed. Multivariate logistic regression models were fitted to explore independent factors for selection bias. Results A total of 22,364 colonoscopies were reported to the National Patient Register of which 15,855 (71â%) were registered in Gastronet. Feedback was received from 11,079 patients (50â%). The frequency of AEs increased from 0.6â% in completeness groupâ<â50â% to 1.6â% in completeness group ≥â90â% ( P â<â0.001). Long colonoscopy procedure time was associated with low reporting completeness. Patient feedback was associated with older age, cecal intubation success and sedation-free colonoscopy. Conclusion Incomplete registration in a colonoscopy quality register is associated with underreporting of AEs. Longer procedure time, a surrogate marker for time constraint, is associated with low completeness.
RESUMO
BACKGROUND: Patients with inflammatory bowel disease [IBD] often suffer from rheumatic manifestations, including inflammatory back disorders. The prevalence of these disorders late in the course of IBD is poorly investigated. The aim of this study was to estimate the prevalence of inflammatory back disorders in patients with IBD 20 years after diagnosis, and to investigate possible associations with IBD severity, HLA-B27, and the NOD2 genotype. METHODS: A population-based cohort [the IBSEN study] was followed prospectively for 20 years. Information covering IBD activity and rheumatic diseases was collected at the regular follow-ups. HLA-B27 and NOD2 were analysed as present or absent. RESULTS: At 20 years, 599 members of the original cohort were alive, of whom 470 [78.5%] were investigated [314 ulcerative colitis and 156 Crohn's disease patients]. Ankylosing spondylitis was diagnosed in 21 patients [4.5%], axial spondyloarthritis was diagnosed in 36 patients [7.7%], and inflammatory back pain was diagnosed in 54 patients [11.5%]. Chronic back pain [back pain > 3 months] was present in 220 patients [46.8%]. HLA-B27 was associated with ankylosing spondylitis, axial spondyloarthritis, and inflammatory back pain, whereas no significant association was found for NOD2. A more chronic IBD course was associated with axial spondyloarthritis. CONCLUSIONS: Our data revealed a high prevalence of ankylosing spondylitis, axial spondyloarthritis, and inflammatory back pain 20 years after the IBD diagnosis. HLA-B27 but not NOD-2 was a predisposing factor for the inflammatory back disorders in IBD patients. Axial spondyloarthritis was associated with a more chronic active IBD disease course.

BACKGROUND AND STUDY AIMS: Some guidelines recommend a minimum standard of 90â% cecal intubation rate (CIR) in routine clinics and 95â% in screening colonoscopy, while others have not made this distinction - both with limited evidence to support either view. This study questions the rationale for making such differentiation. PATIENTS AND METHODS: We assessed cecum intubation rates amongst colonoscopies recorded in the Norwegian national quality register Gastronet by 35 endoscopists performing both clinical and screening colonoscopies. Colonoscopies were categorized into primary screening colonoscopy, work-up colonoscopy of screen-positives and clinical colonoscopy or surveillance. Cases with insufficient bowel preparation or mechanical obstruction were excluded. Endoscopists were categorized into "junior" and "senior" endoscopists depending on training and experience. Univariable and multivariable logistic regression analyses were applied. RESULTS: During a 2-year period, 10,267 colonoscopies were included (primary screening colonoscopy: 746; work-up colonoscopy of screen-positives: 2,604; clinical colonoscopy or surveillance: 6917). The crude CIR in clinical routine colonoscopy, primary screening colonoscopy and work-up colonoscopy was 97.1â%, 97.1â% and 98.6â%, respectively. In a multiple logistic regression analysis, there were no differences in CIR between the 3 groups. Poor bowel cleansing and female sex were independent predictors for intubation failure. CONCLUSION: Cecal intubation rate in clinical colonoscopies and colonoscopy screening are similar. There is no reason to differentiate between screening and clinical colonoscopy with regard to CIR.
RESUMO
Background and aims Patient-reported outcome measures are increasingly important in healthcare. European guidelines have recommended inclusion of patient feedback to capture adverse events due to colonoscopy, but this is rarely implemented. Methods The Norwegian Quality Assurance network for endoscopy (Gastronet) collects patient-reported outcome for colonoscopies. Free-text comments on patient reports from January to December 2015 were characterized as positive or negative. All negative free-text comments were scrutinized for information that might suggest colonoscopy-related adverse events. We identified severe adverse events with and without admission to hospital. Results We included 16 552 outpatient colonoscopies performed at 21 hospitals. A total of 11 248 procedures (68â%) were accompanied by a patient feedback report, of which 2628 (23â%) had free-text comments (2196 [20â%] characterized as positive and 432 [3.8â%] as negative). These negative free texts on patient reports revealed 15 post-colonoscopy hospital admissions due to adverse events that had not been registered in the colonoscopy report. This increased the number of hospital admissions caused by adverse events from 3 (0.03â%) to 18 (0.16â%). In addition, there were 14 patient reports of severe events without hospital admission. Therefore, a total of 29 severe adverse events reported by patients were missed by conventional documentation in the colonoscopy form. Conclusion It is feasible to implement patient feedback as routine reporting to capture the full picture of colonoscopy-related adverse events. Some patients experience significant complications that are not recorded through any registries. Patient feedback forms should be tailored to capture adverse events after colonoscopy that are otherwise not easily disclosed.

OBJECTIVE: The prevalence of persistent villous atrophy (VA) in patients with celiac disease (CD) on a gluten-free diet (GFD) varies greatly between studies. Most studies show a relatively high prevalence of mucosal atrophy and inflammation in treated patients, a finding which have led to a concept of non-responsive CD. Few studies have examined the prevalence of long-term mucosal healing. Our study aimed to determine the extent of mucosal healing in a cohort of Norwegian patients with CD treated with GFD for several years. MATERIALS AND METHODS: Adult patients diagnosed with VA between 1989 and 2009 were included. We performed a follow-up gastroscopy with duodenal biopsies. Two pathologists evaluated the biopsies according to the Marsh-Oberhuber classification. Mucosal healing was defined as Marsh 0 while mucosal recovery was defined as Marsh 0-2. RESULTS: Duodenal biopsies were obtained from 127 adult patients with established CD. After a follow-up time of 8.1 years (median, range 2.3-22.3), 103 (81%) of the patients showed mucosal healing, 120 patients (94%) showed mucosal recovery, and 7 patients (6%) showed persistent VA. In addition, 103 of the 127 patients (81%) had undergone a routine follow-up biopsy 12.6 months (median, range 5.2-28.8) after diagnosis. At the time of the routine follow-up, only 52 of these patients (50.5%) had achieved mucosal recovery. CONCLUSIONS: Although half of the patients had persistent VA at the time of routine follow-up, both long-term mucosal recovery and healing is possible for the vast majority of adult patients with CD.

BACKGROUND & AIMS: The prevalence of primary sclerosing cholangitis (PSC) among patients with inflammatory bowel disease (IBD) is unclear. Patients with IBD might be screened for PSC using magnetic resonance cholangiography (MRC). We aimed to estimate the frequency and distribution of MRC-detected lesions that indicate PSC in patients with IBD 20 years after their initial diagnosis and to identify clinical characteristics associated with these findings. METHODS: We performed a follow-up analysis of a population-based cohort of 756 patients in South-Eastern Norway diagnosed with IBD from January 1, 1990 through December 31, 1993. Of these subjects, 470 attended a follow-up evaluation 20 years later in which they were offered routine clinical blood testing and ileocolonoscopy; 322 were screened by MRC (222 with ulcerative colitis and 100 with Crohn's disease). Two radiologists independently evaluated results from the MRC examinations. RESULTS: In the MRC examination, 24 patients (7.5%) were found to have PSC-like lesions; only 7 of these patients (2.2%) were known to have PSC. One patient was initially missed and 1 had small-duct PSC, so the final prevalence of PSC was 8.1%. Extensive colitis, a high prevalence of colectomy, and chronic and continuous symptoms of IBD occurred in significantly more patients with suspected PSC than without PSC (P = .029, P = .002, and P = .012, respectively). Among patients with subclinical features of PSC, the MRC progression score for PSC increased when they were re-examined after a median 3.2 years (P = .046). CONCLUSIONS: Using MRC analysis of patients with long-term IBD, we found the prevalence of PSC to be around 3-fold higher than that detected based on symptoms. Sixty-five percent of patients had subclinical PSC associated with progressive IBD, with no biochemical abnormalities and mild disease, based on radiology findings. PSC appears to progress in patients with subclinical disease, but long-term outcomes are not known.

BACKGROUND: Data on the long-term observation of health-related quality of life (HRQoL) in the inflammatory bowel diseases (IBD), Crohn's disease (CD), and ulcerative colitis are scarce. Our aim was to determine HRQoL in a population-based cohort of patients with IBD 20 years after diagnosis and its association with demographic and clinical factors and to compare HRQoL of the cohort with that of the background population. METHODS: Patients with IBD from a large population-based inception cohort (the IBSEN cohort) were invited to a prescheduled 20-year follow-up visit with a structured interview, a clinical examination, and laboratory tests. They completed the Short-Form 36 and the Norwegian Inflammatory Bowel Disease Questionnaire. The association between demographic and clinical factors and HRQoL was assessed with a linear regression analysis. Standardized scores were used to compare HRQoL in patients with that of the background population. RESULTS: Of the still-living patients with IBD, 438 (73.1%) completed the HRQoL questionnaires. There were no differences in HRQoL scores between the patients with ulcerative colitis and those with CD. Women with CD obtained scores lower than those of men and women with CD in the background population. Current symptoms, increased disease activity, and not working were identified as factors associated with reduced HRQoL. CONCLUSIONS: In this population-based IBD cohort, the overall HRQoL scores obtained 20 years after diagnosis were relatively unaffected compared with the background population. However, women with CD had lower HRQoL scores than men with CD and women in the background population. Active disease and not working were the main factors associated with impaired HRQoL scores.

IMPORTANCE: Although some countries have implemented widespread colonoscopy screening, most European countries have not introduced it because of uncertainty regarding participation rates, procedure-related pain and discomfort, endoscopist performance, and effectiveness. To our knowledge, no randomized trials on colonoscopy screening currently exist. OBJECTIVE: To investigate participation rate, adenoma yield, performance, and adverse events of population-based colonoscopy screening in several European countries. DESIGN, SETTING, AND POPULATION: A population-based randomized clinical trial was conducted among 94â¯959 men and women aged 55 to 64 years of average risk for colon cancer in Poland, Norway, the Netherlands, and Sweden from June 8, 2009, to June 23, 2014. INTERVENTIONS: Colonoscopy screening or no screening. MAIN OUTCOMES AND MEASURES: Participation in colonoscopy screening, cancer and adenoma yield, and participant experience. Study outcomes were compared by country and endoscopist. RESULTS: Of 31â¯420 eligible participants randomized to the colonoscopy group, 12â¯574 (40.0%) underwent screening. Participation rates were 60.7% in Norway (5354 of 8816), 39.8% in Sweden (486 of 1222), 33.0% in Poland (6004 of 18â¯188), and 22.9% in the Netherlands (730 of 3194) (P < .001). The cecum intubation rate was 97.2% (12â¯217 of 12â¯574), with 9726 participants (77.4%) not receiving sedation. Of the 12â¯574 participants undergoing colonoscopy screening, we observed 1 perforation (0.01%), 2 postpolypectomy serosal burns (0.02%), and 18 cases of bleeding owing to polypectomy (0.14%). Sixty-two individuals (0.5%) were diagnosed with colorectal cancer and 3861 (30.7%) had adenomas, of which 1304 (10.4%) were high-risk adenomas. Detection rates were similar in the proximal and distal colon. Performance differed significantly between endoscopists; recommended benchmarks for cecal intubation (95%) and adenoma detection (25%) were not met by 6 (17.1%) and 10 of 35 endoscopists (28.6%), respectively. Moderate or severe abdominal pain after colonoscopy was reported by 601 of 3611 participants (16.7%) examined with standard air insufflation vs 214 of 5144 participants (4.2%) examined with carbon dioxide (CO2) insufflation (P < .001). CONCLUSIONS AND RELEVANCE: Colonoscopy screening entails high detection rates in the proximal and distal colon. Participation rates and endoscopist performance vary significantly. Postprocedure abdominal pain is common with standard air insufflation and can be significantly reduced by using CO2. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00883792.

BACKGROUND: In chronic inflammatory bowel disease (IBD) (Crohn's disease [CD] and ulcerative colitis [UC]), symptoms from outside the gastrointestinal tract are frequently seen, and the joints, skin, eyes, and hepatobiliary area are the most usually affected sites (called extraintestinal manifestations [EIM]). The reported prevalence varies, explained by difference in study design and populations under investigation. The aim of our study was to determine the prevalence of EIM in a population-based inception cohort in Europe and Israel. METHODS: IBD patients were incepted into a cohort that was prospectively followed from 1991 to 2004. A total of 1145 patients were followed for 10 years. RESULTS: The cumulative prevalence of first EIM was 16.9% (193/1145 patients) over a median follow-up time of 10.1 years. Patients with CD were more likely than UC patients to have immune-mediated (arthritis, eye, skin, and liver) manifestations: 20.1% versus 10.4% (p < 0.001). Most frequently seen was arthritis which was significantly more common in CD (12.9%) than in UC (8.1%), p = 0.01. Pan-colitis compared to proctitis in UC increased the risk of EIM. CONCLUSION: In a European inception cohort, EIMs in IBD were consistent with that seen in comparable studies. Patients with CD are twice as likely as UC patients to experience EIM, and more extensive distribution of inflammation in UC increases the risk of EIM.

BACKGROUND AND STUDY AIMS: Colonoscopy without sedation has several advantages over sedated colonoscopy, but a considerable proportion of patients experience pain. The aim of this study was to develop a risk stratification model of pre-examination risk factors to enable targeted sedation during colonoscopy. PATIENTS AND METHODS: Between October 2011 and January 2012, consecutive outpatients who were willing to start colonoscopy without sedation at 11 Norwegian centers were prospectively recruited. Patients recorded pain on a validated 4-point scale (none, slight, moderate, or severe pain). Potential risk factors for a painful procedure (defined as moderate or severe pain) were evaluated using multivariate logistic regression analyses, and the area under the receiver operating characteristics curve (AUROC) was calculated to assess the discriminatory ability of the derived model. RESULTS: A total of 1198 patients (635 men and 563 women) were included. Seven independent, pre-procedural risk factors for patient pain were identified: female sex, age < 40 years, previous abdominal surgery, abdominal pain as indication for colonoscopy, anticipation of pain, previous painful colonoscopy, and a history of diverticulitis. In patients with 0, 1, 2, or ≥ 3 risk factors, a painful colonoscopy was experienced by 35 %, 43 %, 52 %, and 63 % of women and 18 %, 24 %, 35 %, and 63 % of men, respectively. The model showed modest discrimination abilities (AUROC = 0.69). CONCLUSION: Female sex was a strong risk factor for pain during colonoscopy, and sedation or analgesia should be considered for all women prior to colonoscopy. For male patients, the presence of multiple risk factors should encourage the endoscopist to offer sedation.

BACKGROUND: Colonoscopies are common examinations at Norwegian hospitals. In contrast to many other countries, the majority of colonoscopies in Norway are conducted without routine sedation or analgesia. We wanted to investigate whether current Norwegian practice offers adequate pain relief. MATERIAL AND METHOD: The material consists of prospectively recorded outpatient colonoscopies in the period January 2003-December 2011 performed at Norwegian hospitals in the quality assurance network for gastrointestinal endoscopy (Gastronet). We analysed demographic patient data and data from colonoscopies. Patients' experience of pain (none, slight, moderate or severe pain) in connection with the examination was established with the aid of a validated questionnaire. RESULTS: Data from 61,749 colonoscopies (55% on women) performed at 29 different hospitals were analysed. Colonoscopies were perceived as moderately or very painful by 33% of the patients (41% of the women, 24% of the men, p < 0.001). There were substantial differences between hospitals as to the percentage of colonoscopies that were perceived as moderately or very painful (from 9% to 43%, p < 0.001) and the use of sedatives and analgesics for the colonoscopies (from 1% to 92% of the examinations, p < 0.001). Only 23% of those who found the colonoscopy painful received analgesics. Pethidine was used in 95% of the cases in which analgesics were used during the examination. INTERPRETATION: Many patients find colonoscopies painful. Pain relief practice varies substantially between hospitals. Pethidine is an analgesic with a slow onset of action, and should perhaps be replaced with more rapidly acting opiates.

BACKGROUND: Ulcerative colitis (UC) negatively affects health-related quality of life (HRQoL), but population-based and long-term data on this topic are scarce. Our aim was to determine the HRQoL in UC patients after a 10-year disease duration. METHODS: UC patients from a population-based inception cohort met at a prescheduled 10-year follow-up visit. In addition to a clinical examination, interview, and blood samples, the patients completed the Short Form 36 (SF-36) and the Norwegian Inflammatory Bowel Disease Questionnaire (N-IBDQ). The SF-36 scores were compared to scores from a general population sample using one-sample t-tests. Standardized scores were calculated and interpreted according to Cohen's effect size index. The associations between relevant clinical and demographic factors and HRQoL were examined through linear regression analyses. RESULTS: A total of 196 patients completed the HRQoL questionnaires (response rate: 80%), of whom 54% were women; the mean age of all patients was 48 years (range: 22-86). The SF-36 scores were comparable to those of the general population except for lower scores in the General Health dimension. The SF-36 scores were significantly lower in the presence of current symptoms, in patients who had used corticosteroids, and in patients who reported not working. Overall N-IBDQ scores were equivalent to scores of patients in remission. Female gender, work status (not working), current symptoms, and smoking were associated with significantly lower N-IBDQ scores. CONCLUSIONS: SF-36 scores were not reduced compared to the general population sample. The presence of current symptoms, the use of corticosteroids, work status (not working), female gender, and smoking had a negative impact on HRQoL.

BACKGROUND: Usually, colonoscopy insertion is performed by the colonoscopist (one-person technique). Quite common in the early days of endoscopy, the assisting nurse is now only rarely doing the insertion (two-person technique). Using the Norwegian national endoscopy quality assurance (QA) programme, Gastronet, we wanted to explore the extent of two-person technique practice and look into possible differences in performance and QA output measures. METHODS: 100 colonoscopists in 18 colonoscopy centres having reported their colonoscopies to Gastronet between January and December 2009 were asked if they practiced one- or two-person technique during insertion of the colonoscope. They were categorized accordingly for comparative analyses of QA indicators. RESULTS: 75 endoscopists responded to the survey (representing 9368 colonoscopies) - 62 of them (83%) applied one-person technique and 13 (17%) two-person technique. Patients age and sex distributions and indications for colonoscopy were also similar in the two groups. Caecal intubation was 96% in the two-person group compared to 92% in the one-person group (p < 0.001). Pain reports were similar in the groups, but time to the caecum was shorter and the use of sedation less in the two-person group. CONCLUSION: Two-person technique for colonoscope insertion was practiced by a considerable minority of endoscopists (17%). QA indicators were either similar to or better than one-person technique. This suggests that there may be some beneficial elements to this technique worth exploring and try to import into the much preferred one-person insertion technique.

OBJECTIVE: The present population based adult cohort was part of a new prospective study of patients with inflammatory bowel disease (IBD) in South-Eastern Norway, the Inflammatory Bowel South-Eastern Norway II study, investigating disease characteristics in an attempt to improve our knowledge regarding factors related to early clinical phenotype and disease activity. MATERIAL AND METHODS: Patients suspected to have IBD on the basis of predefined symptoms, including abdominal pain, diarrhea, and/or blood in stool for more than 10 days were examined at the local hospital. Colonoscopy with biopsies was performed and blood and stool samples were taken. RESULTS: In ulcerative colitis (UC) patients, the median Simple Clinical Colitis Activity Index (SCCAI) was 4 (range 0-10) in mild and 6 (range 0-14) in patients with moderate or severe endoscopic activity of inflammation (p = 0.002). The calprotectin concentration in feces was significantly related to the SCCAI (p = 0.034) and the Mayo endoscopic subscore (p = 0.031). There was a significant association between the C-reactive protein (CRP) value, leucocytes and thrombocytes and the SCCAI, but only leucocytes were significantly associated with the Mayo endoscopic subscore. In Crohn's disease (CD) patients, there was no statistical significant association between the Harvey-Bradshaw Index (HBI) and the endoscopic grade of mucosal inflammation (p = 0.8). The calprotectin concentration in feces was significantly related to the endoscopic activity score (p = 0.004), but not to the HBI (p = 0.5). HBI was significantly related to the CRP value (p = 0.047) and thrombocytes (p = 0.03). CONCLUSIONS: In UC, both biochemical and fecal markers are related to disease activity and extent of disease, whereas in CD, the fecal calprotectin concentration is a reliable marker of mucosal affection, but not for systemic disease activity.

BACKGROUND: Knowing the position of the endoscope within the abdomen is important for performing a high-quality, painless colonoscopy. The recently introduced magnetic endoscopic imaging (MEI) system provides a continuous, real-time image of the endoscope during the entire procedure. OBJECTIVE: To compare MEI versus standard colonoscopy with on-demand fluoroscopy on unsedated patients, as performed by experienced and inexperienced endoscopists. DESIGN: Randomized, controlled trial. SETTING: Endoscopy outpatient clinic. PATIENTS: This study involved 810 consecutive patients (391 randomized to standard group; 419 randomized to MEI) referred for colonoscopy. INTERVENTION: MEI or standard approach (involving on-demand fluoroscopy) during colonoscopy. MAIN OUTCOME MEASUREMENTS: Perceived patient pain and cecal intubation rate and time to cecum. RESULTS: For inexperienced endoscopists, the cecal intubation rate was significantly higher in the MEI group (77.8%) compared with the standard group (56.0%), P = .02 but not for experienced endoscopists (94.0% for MEI and 96.0% for standard group, P = .87). Inexperienced endoscopists had less need for assistance from a senior colleague when they used MEI (18.5%) compared with the standard technique (40.0%), P = .02. Mean (± standard deviation) time to reach the cecum was 14.0 ± 12.2 minutes in the MEI group and 15.3 ± 14.2 minutes in the standard group, P = .67. LIMITATIONS: Single center, unblinded study. CONCLUSION: Inexperienced endoscopists improved their colonoscopy performance when they used MEI, compared with the standard technique, but experienced endoscopists did not. The MEI may be advantageous to use for colonoscopy centers educating endoscopists. ( CLINICAL TRIAL REGISTRATION NUMBER: NCT00519129.).

OBJECTIVE: An important challenge of any quality assurance (QA) programme is to maintain interest among participants to ensure high data quality over time. The primary aim of this study was to identify factors associated with endoscopist compliance with the Norwegian QA programme for colonoscopies (Gastronet). MATERIAL AND METHODS: The Gastronet registration tools are an endoscopy report form to be filled in directly after the procedure by the endoscopist, and a satisfaction questionnaire to be filled in by the patient on the day after the examination. During the study period from 1 January 2004 to 31 December 2006, endoscopist compliance was measured by assessing patient report coverage, defined as the percentage of patient satisfaction questionnaires received by the Gastronet secretariat divided by the total number of colonoscopy reports registered by the individual endoscopists during the study period. Multivariate logistic regression models were applied to identify individual factors related to patient report coverage. RESULTS: Eighty-eight endoscopists from 10 hospitals contributed a total of 16,149 colonoscopies. Overall patient report coverage decreased from 87% in 2004 to 80% in 2006. A low patient report coverage was associated with time since the registrations started [odds ratio (OR) 0.98, 95% confidence interval (CI) 0.97-0.98; P < 0.001], use of sedation (OR 0.7, 95% CI 0.61-0.76; P < 0.001), and incomplete colonoscopy (OR 0.6, 95% CI 0.54-0.76; P < 0.001). CONCLUSIONS: Decreasing compliance with registration over time may compromise data quality and the validity of the results. Lower coverage of patient's reports (presumably for the most difficult examinations) may lead to erroneous conclusions regarding colonoscopy performance.

OBJECTIVE: Intravenous proton pump inhibitors (PPIs) induce a high intragastric pH and may thereby improve haemostasis in patients with bleeding peptic ulcer. The aim of this study was to investigate whether a similar therapeutic intragastric pH level could be reached when the PPI was administered orally. MATERIAL AND METHODS: Twenty-four-hour intragastric pH was measured in patients treated endoscopically for bleeding peptic ulcer (Forrest class I or II). The patients received lansoprazole capsules (90 mg) after successful endoscopic treatment, followed by 30 mg every third hour for 72 h. The primary end-point was the percentage of the 0 to 24-h registration period with an intragastric pH of 6 or higher. Additionally, the total number of patients obtaining an intragastric pH above 6 for 80% or more of the 0 to 24-h period after start of treatment was evaluated. RESULTS: Of the 14 patients included in the study (4 F, mean age 74 years, range 50-84 years), 10 patients had duodenal ulcer and 4 had gastric ulcer; median lowest Hgb: 8.9 mg/ml (range 5.8-12.4), blood transfusions: 2.7 SAG units (range 0-7). In the 0 to 24-h period, the median time duration of pH above 6 was 55% (range 6-99). One out of 14 patients (7%) reached a pH above 6 in at least 80% of this time period. CONCLUSIONS: An increase in intragastric pH of therapeutic importance was reached with this oral medication regimen. However, there were large intra-individual differences. Treatment with oral lansoprazole may be a therapeutic alternative to intravenous administration of PPI.

OBJECTIVES: Perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) and anti-Saccharomyces cerevisiae antibody (ASCA) have been proposed as markers for diagnosis and for subtyping of inflammatory bowel disease (IBD). The aim of this study was to investigate the association of p-ANCA and ASCA with a 10-year disease outcome in terms of cumulative rate of colectomy and relapse in a population-based European inception cohort of ulcerative colitis (UC) patients. METHODS: Serum samples from 432 consenting patients were analysed for p-ANCA and ASCA. The results were compared with the cumulative colectomy rate, relapsing disease and total number of relapses. We used multiple regression analyses adjusted for age, sex, residence, disease extent at diagnosis, smoking, familial IBD and drug treatment to study the relationship between serological values and disease course. RESULTS: The relapse rate was higher in the p-ANCA-positive patients: 82% (95% confidence interval [CI] 75-89%) compared with 67% (CI 62-72%, p=0.011) in the p-ANCA-negative patients. The risk of relapsing disease course was higher by a factor of 1.4 (CI 1.1-1.8, p=0.009) for p-ANCA-positive patients than for p-ANCA-negative patients, and the corresponding relative risk (RR) for the total number of relapses was 1.9 (CI 1.7-2.1, p<0.001). In ASCA-positive patients RR for the total number of relapses was 1.8 (CI 1.5-2.1, p<0.001). No significant association with colectomy rate was found for the presence of either p-ANCA or ASCA. CONCLUSION: UC patients positive for p-ANCA and possibly for ASCA may have a more unfavourable long-term disease outcome in terms of relapse than UC patients without these markers.
