RESUMEN
BACKGROUND AND STUDY AIM: To reduce the costs of colonoscopy the feasibility of unsedated procedures has been explored. The aims of our study were to assess patient satisfaction with on-demand sedation and identify factors related to painful colonoscopy. PATIENTS AND METHODS: The Norwegian Gastronet quality assurance documentation tools consist of endoscopy reports (completed on site) and a patient satisfaction questionnaire (completed by the patient on the day after colonoscopy). Data were collected from January 1 2004 to December 31 2006. Colonoscopies reported to be moderately or severely painful were defined as "painful colonoscopy." RESULTS: Nine endoscopy centers representing 86 endoscopists reported 14 915 examinations and 12 354 patient reports were returned (83 % response rate). Patient satisfaction with service and information given was greater than 95 % for all centers. Mean rate of painful colonoscopy was 34 % and mean sedation rate 34 %. Odds ratio (OR) for painful colonoscopy was 2.2 ( P < 0.001) when sedation was given. The ORs for painful colonoscopy were similar for all but one center (no. 4) with OR 1.6 ( P = 0.04), while the OR for giving sedation was higher for all but one center (no. 1) compared with the reference center (ORs 2.2 to 7.5, all P-values < 0.001). CONCLUSION: A surprisingly high rate of painful colonoscopy was found. High sedation rates were not associated with low rates of painful colonoscopy. Recommending increased sedation rates as the only intervention to improve suboptimal performance might not lead to lower rates of painful colonoscopy.

UNLABELLED: Fecal calprotectin (CPT) is elevated in the majority of patients with known colorectal cancer (CRC), but the specificity is not clarified. AIM: To evaluate if a CPT test (PhiCal ELISA) was more sensitive than Hemoccult II test in detecting colorectal neoplasia, and to obtain reference values in subjects with normal colonoscopy. To evaluate a possible relation between number and extent of dysplasia of adenomas in first degree relatives of patients with CRC and the stage of the carcinoma in the index casus. Further to study the prevalence of CRC and adenomas in the first degree relatives of patients operated for CRC. METHOD: In a multicenter study, 253 first degree relatives of patients with CRC, aged 50-75 years (mean age 60 years) underwent colonoscopy after having delivered stool samples and three Hemoccult II slides. RESULTS: In 237 first degree relatives from 148 patients with CRC, polyps were found in 118 (50%). Seventy three (31%) had adenomas and 17 had adenomas > or =10 mm. Five had asymptomatic cancers. The specificity of fecal CPT for adenomas at cut off levels

BACKGROUND: The extent of bone density reduction in patients with Crohn disease is still being debated. The aim of this study was to examine bone mineral density (BMD) and factors associated with reduced BMD in a representative population of patients with Crohn disease aged between 20 and 70 years. METHODS: BMD (using dual energy X-ray absorptiometry) was measured in spine and hip in 55 patients with Crohn disease recruited from the entire Crohn population (n = 96) in a defined area of southern Norway. Demographic and clinical data were also collected. The patients were compared with 52 age- and gender-matched healthy controls. Potential demographic and disease-related factors associated with BMD reduction were statistically tested with bi- and multivariate analyses. RESULTS: The BMD reduction in patients with Crohn disease was 7.1% (P = 0.02) in spine L1-4, 6.1% (P = 0.08) in femoral neck and 8.4% (P = 0.02) in total hip as compared with the controls. In total hip and femoral neck, age, body weight and gender were independently associated with reduced BMD, but in the spine only body weight. Among the disease-related variables, only ever use of prednisolone was independently associated with reduction in BMD but this only in the femoral neck. CONCLUSIONS: The spine and hip BMD reduction of 6%-8% is similar to that found in a comparable population-based study performed in another area in Norway. Among the disease-related variables tested for, only the use of prednisolone was independently associated with BMD reduction. However, the BMD reduction measured in this study indicates that disease-related mechanisms are involved.

BACKGROUND: Early detection of cobalamin deficiency is clinically important, and there is evidence that such deficiency occurs more frequently than previously anticipated. However, serum cobalamin and other commonly used tests have limited ability to diagnose a deficiency state. METHODS: We investigated the ability of hematological variables, serum cobalamin, plasma total homocysteine (tHcy), serum and erythrocyte folate, gastroscopy, age, and gender to predict cobalamin deficiency. Patients (n = 196; age range, 17-87 years) who had been referred from general practice for determination of serum cobalamin were studied. Cobalamin deficiency was defined as serum methylmalonic acid (MMA) >0.26 micromol/L with at least 50% reduction after cobalamin supplementation. ROC and logistic regression analyses were used. RESULTS: Serum cobalamin and tHcy were the best predictors, with areas under the ROC curve (SE) of 0. 810 (0.034) and 0.768 (0.037), respectively, but age, intrinsic factor antibodies, and gastroscopy gave additional information. CONCLUSIONS: When cobalamin deficiency is suspected in general practice, serum cobalamin should be the first diagnostic test, and the result should be interpreted in relation to the age of the patient. When a definite diagnosis cannot be reached, MMA and tHcy determination will provide additional discriminative information, but MMA, being more specific, is preferable for assessment of cobalamin status.

To evaluate the therapeutic potential of the newly developed proton pump inhibitor lansoprazole in patients with reflux oesophagitis, we performed a double-blind randomized clinical trial comparing 20 mg omeprazole and 30 mg lansoprazole, involving 229 patients at 9 Scandinavian hospitals. The treatment period was 4 or 8 weeks, and main efficacy variables were healing of endoscopic changes, relief of reflux symptoms, and occurrence of adverse events. No significant difference in terms of healing was found, either after 4 or after 8 weeks' treatment. Patients receiving lansoprazole experienced a greater improvement in heartburn after 4 weeks (p = 0.03), and there was a similar trend for acid regurgitation. Lansoprazole was found to be an effective and safe alternative to omeprazole in short-term treatment of moderate reflux oesophagitis.

Today, most upper GI-haemorrhages can be handled without surgery. We discuss the available endoscopic haemostatic methods. Injection therapy seems to be as effective as laser-, heater probe- and bipolar electrocoagulation, and is often preferred because the equipment is inexpensive. In a pilot study of 37 patients with haemorrhage from peptic ulcer (13 with active bleeding and 24 with stigmata of recent hemorrhage) we injected thrombin in the ulcer base and treated the patients systemically with an antifibrinolytic drug (tranexamic acid) for five days. Endoscopic follow-up revealed stigmata of recent haemorrhage in 23 patients on day 1 and in eight patients on day 5. "Blood in stomach" was seen in eight patients on day 1 and in two patients on day 5. Four patients had clinical signs of rebleeding, but only one of them needed operation (definite hemostasis 97%). There were no obvious side effects of the treatment. Contrary to other endoscopic methods, local injection of thrombin does not damage the normal mucosa. However, the method has not been sufficiently explored as yet, and cannot be recommended without strict control and follow-up measures. Early control endoscopy seems to be a sensitive way of monitoring haemostasis.

In a double-blind, randomized, multicenter trial 150 consecutive outpatients with endoscopically verified duodenal ulcer were treated with either a low-dose antacid regimen (1 tablet q.i.d.; acid-neutralizing capacity, 120 mmol/day), or cimetidine (800 mg nocte). After 4 wk of treatment control gastroscopy showed ulcer healing in 54 of 76 patients (71.1%) in the antacid group, as compared with 58 of 74 patients (78.4%) in the cimetidine-treated group. The difference in healing rate of 7.3% (95% confidence interval, -6.5% to +21.1%) was not statistically significant. The symptomatic effect, measured as number of days and nights with ulcer pain, was also quite similar in the two treatment groups. However, the number of days with pain was significantly lower in the first week of treatment in the antacid group (p less than 0.01). Thus, the efficacy of a low-dose antacid tablet regimen approximated that of cimetidine (800 mg nocte) in the treatment of duodenal ulcer patients.
