Abstract
In each case of extraintestinal manifestations of Crohn's disease, active disease, if present, should be treated to induce remission, which may positively influence the course of most concomitant extraintestinal manifestations. For some extraintestinal manifestations, however, a specific treatment should be introduced. This latter part of disease management will be discussed in this chapter, in particular for pyoderma gangrenosum, uveitis, spondylarthropathy--axial arthropathy--and primarysclerosing cholangitis, which have also been described in quiescent Crohn's disease. Few new drugs for the treatment of extraintestinal manifestations of Crohn's disease have been developed in the past and only the role of infliximab has increased in Crohn's disease-related extraintestinal manifestations. Drugs specifically aimed at this treatment, stemming from a few randomized controlled studies or case series, are sulfasalazine, 5-ASA, corticosteroids, azathioprine or 6-mercaptopurine, methotrexate, infliximab, dapsone and cyclosporine or tacrolimus.

Abstract
BACKGROUND/AIM Roughly 50% of patients with chronic hepatitis C, who relapsed after a previous monotherapy with interferon alpha, will respond in a sustained fashion to 24 weeks of re-therapy with the combination of interferon alpha plus ribavirin. Whether prolonging treatment duration to 48 weeks will further increase sustained response rates remains ill defined. In this randomised controlled pilot trial we compared the efficacy and tolerability of a 24 week with that of a 48 week course of combination therapy with interferon alpha and ribavirin in interferon monotherapy relapsers with chronic hepatitis C. METHODS Interferon alpha monotherapy relapsers with chronic hepatitis C were randomised to receive interferon alpha 2b (3 x 3 MIU sc weekly) and oral ribavirin (1000/1200 mg po daily) for either 24 weeks or 48 weeks. Virological response was evaluated by HCV RNA PCR at week 10 (initial response), at the end of treatment (end of- treatment response) and at the end of 24 weeks follow-up (sustained response). Only patients with negative HCV RNA at week 10 continued treatment. Adverse events were recorded at regular intervals. RESULTS Thirty-seven patients were enrolled, 19 (6 females, median age 43) in the 24 week and 18 (5 females, median age 40) in the 48 week treatment arm. Baseline characteristics were similar in both groups. At treatment week 10, 12/19 (63%) in the 24 week group and 14/18 (78%) patients in the 48 week group had lost HCV RNA in serum (p = 0.33). All initial responders remained HCV RNA negative throughout the treatment period. Sustained response rates were 10/19 (53%) in the 24 week group and 13/18 (72%) in the 48 week group (p = 0.31). Three patients discontinued treatment early (two due to moderate adverse events, one due to non-compliance). Dose modifications were necessary in 9 patients, 4 in the 24 week and 5 in the 48 week group for anaemia, neutropenia, nausea and depression, respectively. CONCLUSION Prolonging interferon / ribavirin combination therapy in interferon alpha monotherapy relapsers with chronic hepatitis C from 24 to 48 weeks may increase sustained response rates. Larger controlled trials using pegylated interferon alpha and ribavirin in relapsers with chronic hepatitis C seem warranted.

Abstract
OBJECTIVES To assess the degree of agreement between appropriateness criteria for the use of colonoscopy developed by a standardized expert panel method and evidence from published studies. DESIGN Descriptive, agreement study. SETTING Multidisciplinary panel; primary care practice in Switzerland. PARTICIPANTS Nine national experts; 577 primary care patients referred for colonoscopy, 154 published papers. INTERVENTIONS Evaluation of the appropriateness of 402 possible clinical indications for colonoscopy, based on a comprehensive review of the literature. MAIN OUTCOMES MEASURES Proportion of agreement (weighted kappa), between panel- and literature-based appropriateness categories (appropriate, uncertain, inappropriate) for theoretical and actual indications encountered. RESULTS Nineteen of 402 indications rated by the panel could be based on the evidence retrieved from eight randomized clinical trials. A 68% agreement (kappa = 0.52) was found between panel- and study-based criteria. The addition of an uncontrolled trial and seven observational studies yielded a 71% agreement (kappa = 0.63). Agreement was similar when examining 577 actual cases: 69% agreement, kappa = 0.47. Agreement between panel-based indications and published evidence was not influenced by the perceived comprehensiveness and the apparent quality of the published reports. CONCLUSIONS Evidence for the appropriateness of most indications for colonoscopy could not be derived directly from the published literature. Agreement between appropriateness criteria developed by an expert panel and evidence from published studies was moderate to good, where available. New approaches should be sought in order to systematically integrate complementary evidence obtained from clinical trials and expert panels into practice guidelines.

Abstract
BACKGROUND AND STUDY AIMS Appropriateness of use of colonoscopy is an important issue in health care in the quest to improve quality of care while at the same time containing costs. This prospective study examined whether detailed and explicit appropriateness criteria significantly improve the diagnostic yield of colonoscopy. PATIENTS AND METHODS Consecutive patients referred for diagnostic colonoscopy at five centers (one university hospital and its outpatient department, two district hospitals, and two gastroenterology practices) were prospectively studied over a 17-month period. The appropriateness of the indications for these colonoscopies was assessed using explicit Swiss criteria developed by the Rand Corporation/University of California at Los Angeles (RAND/UCLA) panel method, and the relationship between appropriateness of use and the presence of clinically relevant endoscopic lesions was analysed. RESULTS 1188 patients were included in the study. Indications for 1144 (96.3 %) of the colonoscopies could be evaluated using explicit criteria; 64.1 % of the colonoscopies were judged appropriate, 13.3 % uncertain and 22.6 % inappropriate. Significant endoscopic lesions were found in 23.8 % of the colonoscopies. Colonoscopies judged appropriate or uncertain yielded significantly more relevant lesions than did those judged to be inappropriate (25.6 % vs. 17.4 %; P = 0.007). Of 51 colon cancers, all but one were found in colonoscopies judged to be appropriate or uncertain. In a multivariate analysis, the diagnostic yield of colonoscopy was significantly influenced by appropriateness, patient gender and treatment setting. CONCLUSIONS The use of detailed and explicit appropriateness criteria for colonoscopy significantly enhances the identification of relevant lesions and in particular of colon cancer. The use of such criteria could therefore improve patient selection for colonoscopy and thus contribute to efforts aimed at enhancing the quality and efficiency of care.

Abstract
Recent controlled trials on the efficacy of an amantadine/interferon combination in treatment-naive patients with chronic hepatitis C yielded contradictory results. We therefore conducted a large, double-blind, placebo-controlled, multicenter trial in naive patients with chronic hepatitis C: 246 patients were randomized to receive interferon alfa-2a (6 MIU sc thrice weekly for 20 weeks, then 3 MIU sc thrice weekly) and either amantadine sulphate (2 x 100 mg p.o. QD) or placebo. Treatment continued for a total of 52 weeks, if HCV-RNA in serum polymerase chain reaction (PCR) had fallen below detection limit (1,000 copies/mL) at treatment week 10, and stopped otherwise. All patients were followed for 24 weeks off therapy. After 10 weeks of treatment, 66/121 patients treated with amantadine (55%) and 78/125 treated with placebo (62%) had lost HCV-RNA (n.s.). After 24 weeks of follow-up, 25 patients in the amantadine (21%) and 17 (14%) in the placebo group remained HCV-RNA negative (n.s.). During therapy, virologic breakthroughs occurred less often in the amantadine than in the placebo group [14 (12%) vs. 27 (22%) patients; P =.04]. Multivariate logistic regression analysis revealed genotype, viremia level, age, and amantadine therapy [risk ratio 0.4 (95%CI 0.2-1.0), P =.05] as predictors of sustained virologic response. Adverse events and impact of therapy on quality of life were similar in amantadine and placebo treated patients. Compared with current standard treatment (interferon/ribavirin), the interferon/amantadine combination was not cost-effective. In conclusion, amantadine does not add to a clinically relevant extent to the treatment of naive patients with chronic hepatitis C.

Abstract
OBJECTIVES The aim of this study was to assess the still controversial role of treatment of Helicobacter pylori (H. pylori) infection in patients with nonulcer dyspepsia. METHODS We conducted a double-blind, randomized, placebo-controlled, multicenter trial comparing the efficacy of 7 days of eradication treatment (lansoprazole 15 mg b.i.d., amoxicillin I g b.i.d., and clarithromycin 500 mg b.i.d.) with a control treatment (lansoprazole 15 mg b.i.d. and placebo) in H. pylori-infected patients with nonulcer dyspepsia. 13C breath tests were performed at baseline and during follow-up. We assessed patient symptoms, health status (based on the SF-12 questionnaire), patient satisfaction, drug consumption, health care consultation behavior, and absenteeism related to dyspepsia over a 1-yr period. RESULTS A total of 74 patients randomized to eradication treatment and 70 patients randomized to placebo were compared. The rate of eradication of H. pylori infection was 75% in the active treatment group and 4% in the placebo group (p < 0.005). The symptom score improved to a similar extent in the group receiving active treatment (-4.0; 95% CI = -5.0 to -3.0) and placebo (-3.6; 95% CI = -4.5 to -2.7). Treatment response was not related to the severity or duration of initial symptoms or to the severity of gastritis on histology. Quality of life scores were comparable at 12 months. There was no significant difference in dyspepsia-related absenteeism or satisfaction with management of NUD. Patients receiving active treatment were more likely not to have had to use any dyspepsia treatment over the 12 months (60.8% vs 44.3%; p = 0.047). CONCLUSIONS This study did not demonstrate any substantial benefit of curing H. pylori infection in patients with nonulcer dyspepsia. The study adds further evidence that H. pylori is not the main pathogenetic or therapeutic target in these patients.

Abstract
BACKGROUND Efforts to decrease overuse of health care may result in underuse. Overuse and underuse of colonoscopy have never been simultaneously evaluated in the same patient population. METHODS In this prospective observational study, the appropriateness and necessity of referral for colonoscopy were evaluated by using explicit criteria developed by a standardized expert panel method. Inappropriate referrals constituted overuse. Patients with necessary colonoscopy indications who were not referred constituted underuse. Consecutive ambulatory patients with lower gastrointestinal (GI) symptoms from 22 general practices in Switzerland, a country with ready access to colonoscopy, were enrolled during a 4-week period. Follow-up data were obtained at 3 months for patients who did not undergo a necessary colonoscopy. RESULTS Eight thousand seven hundred sixty patient visits were screened for inclusion; 651 patients (7.4%) had lower GI symptoms (mean age 56.4 years, 68% women). Of these, 78 (12%) were referred for colonoscopy. Indications for colonoscopy in 11 patients (14% of colonoscopy referrals or 1.7% of all patients with lower GI symptoms) were judged inappropriate. Among 573 patients not referred for the procedure, underuse ranged between 11% and 28% of all patients with lower GI symptoms, depending on the criteria used. CONCLUSIONS Applying criteria from an expert panel of nationally recognized experts indicates that underuse of referral for colonoscopy exceeds overuse in primary care in Switzerland. To improve quality of care, both overuse and underuse of important procedures must be addressed.

Abstract
BACKGROUND Increasing the appropriateness of use of upper gastrointestinal (GI) endoscopy is important to improve quality of care while at the same time containing costs. This study explored whether detailed explicit appropriateness criteria significantly improve the diagnostic yield of upper GI endoscopy. METHODS Consecutive patients referred for upper GI endoscopy at 6 centers (1 university hospital, 2 district hospitals, 3 gastroenterology practices) were prospectively included over a 6-month period. After controlling for disease presentation and patient characteristics, the relationship between the appropriateness of upper GI endoscopy, as assessed by explicit Swiss criteria developed by the RAND/UCLA panel method, and the presence of relevant endoscopic lesions was analyzed. RESULTS A total of 2088 patients (60% outpatients, 57% men) were included. Analysis was restricted to the 1681 patients referred for diagnostic upper GI endoscopy. Forty-six percent of upper GI endoscopies were judged to be appropriate, 15% uncertain, and 39% inappropriate by the explicit criteria. No cancer was found in upper GI endoscopies judged to be inappropriate. Upper GI endoscopies judged appropriate or uncertain yielded significantly more relevant lesions (60%) than did those judged to be inappropriate (37%; odds ratio 2.6: 95% CI [2.2, 3.2]). In multivariate analyses, the diagnostic yield of upper GI endoscopy was significantly influenced by appropriateness, patient gender and age, treatment setting, and symptoms. CONCLUSIONS Upper GI endoscopies performed for appropriate indications resulted in detecting significantly more clinically relevant lesions than did those performed for inappropriate indications. In addition, no upper GI endoscopy that resulted in a diagnosis of cancer was judged to be inappropriate. The use of such criteria improves patient selection for upper GI endoscopy and can thus contribute to efforts aimed at enhancing the quality and efficiency of care.

Abstract
The balance between risks and benefits of gastrointestinal endoscopy for a given patient is essential in defining the appropriate use of endoscopic procedures. The current literature suggests that gastrointestinal endoscopy infrequently results in major procedure-related morbidity and mortality, while cardio-respiratory events occur commonly. However, true complication rates may be underestimated due to inconsistencies in the types of complications reported. No formal reporting requirements exist, and most of the published studies on complications come from centres with highly-skilled endoscopists.

Abstract
We here report the case history of a 75-yr-old woman who developed pancreatitis and recurrent symptomatic, cholestasis-induced hemobilia after percutaneous liver biopsy. An endoscopic sphincterotomy with clot extraction led to relief of symptoms. The risk of hemobilia after percutaneous liver biopsy is less than one per 1000 procedures, and only two cases of acute pancreatitis after percutaneous liver biopsy have previously been reported. To our knowledge, this is the first case in which endoscopic retrograde cholangiopancreatography was used to both diagnostic and therapeutic ends.
