  Bariatric surgery is the most effective treatment for obesity but is invasive and associated with serious complications. Endoscopic sleeve gastroplasty (ESG) is a less invasive weight loss procedure to reduce the stomach volume by full-thickness sutures. ESG has been adopted in many countries, but implementation at Scandinavian centres has not yet been documented. We performed a clinical pilot trial at a Norwegian centre with the primary objective to assess the feasibility of the ESG procedure. Patients and methods We included the first 10 patients treated with ESG at a Norwegian centre in a single-arm pilot study. The eligibility criteria were either a body mass index (BMI) of 40–49.9 kg/m2, BMI 35–39.9 kg/m2 and at least one obesity-related comorbidity, or BMI 30–34.9 kg/m2 and type 2 diabetes. Patient follow-up resembled the scheme used for bariatric surgery at the center, including dietary plans and outpatient visits. Results All procedures were technically successful except for one patient who had adhesions between the stomach and anterior abdominal wall, related to a prior hernia repair, resulting in less-than-intended stomach volume reduction. Mean total body weight loss (TBWL) after 26 and 52 weeks was 12.2% (95% CI 8.1–16.2) and 9.1% (95% CI 3.3 − 15.0). One patient experienced a minor suture-induced diaphragmatic injury, which was successfully managed conservatively. Conclusions This first Scandinavian clinical trial of ESG, documenting the implementation of the procedure at a Norwegian center, demonstrated acceptable feasibility and safety, with large variations in individual weight loss during the 52-week follow-up period.

  Introduction Gastro-esophageal reflux disease (GERD) occurs frequently in patients operated for esophageal atresia (EA). Longstanding esophagitis may lead to dysphagia, strictures, columnar metaplasia, and dysplasia with an increased risk of adenocarcinoma. Are clinical factors and non-invasive assessments reliable indicators for follow-up with endoscopy? Material and method A follow-up study with inclusion of EA adolescents in Norway born between 1996 and 2002 was conducted. Clinical assessment with pH monitoring, endoscopy with biopsies, along with interviews and questionnaires regarding gastroesophageal reflux disease (GERD) and dysphagia were performed. Results We examined 68 EA adolescents. 62% reported GERD by interview, 22% by questionnaire. 85% reported dysphagia by interview, 71% by questionnaire. 24-hour pH monitoring detected pathological reflux index (RI) (>7%) in 7/59 (12%). By endoscopy with biopsy 62 (92%) had histologic esophagitis, of whom 3 (4%) had severe esophagitis. Gastric metaplasia was diagnosed in twelve (18%) adolescents, intestinal metaplasia in only one (1.5%). None had dysplasia or carcinoma. Dysphagia and GERD were statistically correlated to esophagitis and metaplasia, but none of the questionnaires or interviews alone were good screening instruments with high combined sensitivity and specificity. A compound variable made by simply taking the mean of rescaled RI and dysphagia by interview showed to be the best predictor of metaplasia (85% sensitivity, 67% specificity). Conclusion The questionnaires and interviews used in the present study were not good screening instruments alone. However, combining dysphagia score by interview and RI may be helpful in assessing which patients need endoscopy with biopsy at each individual follow-up examination.

  Background: Low-grade immune activation in the gut is a potential treatment target in irritable bowel syndrome (IBS). Aims: To determine improvement in IBS symptoms after mesalazine treatment, and the utility of measures of immune activity in the rectal mucosa METHODS: This was a randomised, double-blind, placebo-controlled, parallel-arm, multicentre trial in subjects with IBS (Rome III criteria), with an eight-week treatment period of mesalazine 2400 mg or plcebo once-daily. The primary endpoint was the global assessment of satisfactory relief of IBS symptoms in ≥50% of weeks during intervention. IBS symptoms were also measured with the IBS severity scoring system; immune activity was measured by mucosal patch technology. A post hoc meta-analysis of randomised placebo-controlled trials of mesalazine in IBS was added. Results: Of 181 included patients, 91 received mesalazine and 90 received placebo. The primary endpoint was met by 32 (36%) patients after mesalazine and 27 (30%) after placebo (p = 0.40). There were no differences in response rates related to IBS subtype or post-infection symptom onset. More reduction of abdominal bloating was noted in the mesalazine group (p = 0.02). The meta-analysis showed no effect of mesalazine on IBS symptoms. No mucosal patch technology measure could predict response to mesalazine, and found no differences in the effects of intervention on levels of immune markers. Conclusions: Mesalazine is ineffective in reducing IBS symptoms. Rectal measures of immune activity by the mucosal patch technology cannot predict a higher chance of response to mesalazine.

  Background & Aims A gluten-free diet usually leads to mucosal remission in celiac disease, but persistent symptoms are common. A low fermentable oligo-, di-, monosaccharides and polyols (FODMAP) diet is an established treatment for irritable bowel syndrome (IBS). We have assessed the efficacy of a moderately low FODMAP diet on persistent symptoms in treated celiac patients. Methods A randomized controlled trial was performed from 2018 to 2019 in 70 adults with biopsy-proven celiac disease. Inclusion criteria were as follows: persistent gastrointestinal symptoms defined by a Gastrointestinal Symptom Rating Scale (GSRS)–IBS version score of 30 or higher, gluten-free diet adherence for 12 months or longer, and serologic and mucosal remission. Participants were randomized to a low FODMAP–gluten-free diet (intervention) or usual gluten-free diet (control). The GSRS-IBS score was recorded at baseline and at weeks 1 to 4, and the Celiac Symptom Index at baseline and at week 4. Statistics included marginal models for repeated data and analyses of covariance. Results We included 34 participants in the intervention group and 36 in the control group. Time development of GSRS–IBS total scores differed significantly between the groups (Pinteraction < .001), evident after 1 week (mean difference in intervention vs control, -8.2; 95% CI, -11.5 to -5.0) and persisting through week 4 (mean difference in intervention vs control, -10.8; 95% CI, -14.8 to -6.8). Moreover, significantly lower scores were found for the dimensions of pain, bloating, diarrhea, and satiety (Pinteraction ≤ .04), but not constipation (Pinteraction = .43). FODMAP intake during the intervention was moderately low (mean, 8.1 g/d; 95% CI, 6.7–9.3 g/d). The Celiac Symptom Index was significantly lower in the intervention group at week 4 (mean difference, -5.8; 95% CI, -9.6 to -2.0). Conclusions A short-term moderately low FODMAP diet significantly reduced gastrointestinal symptoms and increased celiac disease–specific health, and should be considered for the management of persistent symptoms in celiac disease.

  Background: Systematic training in colonoscopy is highly recommended; however, we have limited knowledge of the effects of "training-the-colonoscopy-trainer" (TCT) courses. Using a national quality register on colonoscopy performance, we aimed to evaluate the effects of TCT participation on defined quality indicators. Methods: This observational study compared quality indicators (pain, cecal intubation, and polyp detection) between centers participating versus not participating in a TCT course. Nonparticipating centers were assigned a pseudoparticipating year to match their participating counterparts. Results were compared between first year after and the year before TCT (pseudo)participation. Time trends up to 5 years after TCT (pseudo)participation were also compared. Generalized estimating equation models, adjusted for age, sex, and bowel cleansing, were used. Results: 11 participating and 11 nonparticipating centers contributed 18 555 and 10 730 colonoscopies, respectively. In participating centers, there was a significant increase in detection of polyps ≥ 5 mm, from 26.4 % to 29.2 % (P = 0.035), and reduction in moderate/severe pain experienced by women, from 38.2 % to 33.6 % (P = 0.043); no significant changes were found in nonparticipating centers. Over 5 years, 20 participating and 18 nonparticipating centers contributed 85 691 and 41 569 colonoscopies, respectively. In participating centers, polyp detection rate increased linearly (P = 0.003), and pain decreased linearly in women (P = 0.004). Nonparticipating centers did not show any significant time trend during the study period. Conclusions: Participation in a TCT course improved polyp detection rates and reduced pain experienced by women. These effects were maintained during a 5-year follow-up.

  To decrease colon polyp miss-rate during colonoscopy, a real-time detection system with high accuracy is needed. Recently, there have been many efforts to develop models for real-time polyp detection, but work is still required to develop real-time detection algorithms with reliable results. We use single-shot feed-forward fully convolutional neural networks (F-CNN) to develop an accurate real-time polyp detection system. F-CNNs are usually trained on binary masks for object segmentation. We propose the use of 2D Gaussian masks instead of binary masks to enable these models to detect different types of polyps more effectively and efficiently and reduce the number of false positives. The experimental results showed that the proposed 2D Gaussian masks are efficient for detection of flat and small polyps with unclear boundaries between background and polyp parts. The masks make a better training effect to discriminate polyps from the polyp-like false positives. The proposed method achieved state-of-the-art results on two polyp datasets. On the ETIS-LARIB dataset we achieved 86.54% recall, 86.12% precision, and 86.33% F1-score, and on the CVC-ColonDB we achieved 91% recall, 88.35% precision, and F1-score 89.65%.

  Dysphagia and obstruction are among the most common indications for upper gastrointestinal endoscopy in African countries [1]. In a survey conducted by the European Society of Gastrointestinal Endoscopy (ESGE) International Affairs Working Group (IAWG), benign esophageal strictures as well as malignant upper gastrointestinal obstruction were reported as some of the most prevalent diseases leading to gastrointestinal endoscopy [1]. Management of esophageal obstruction may vary, depending on the cause of obstruction as well as the availability of resources. According to the ESGE original guideline, it could involve, for example, stent placement, radiotherapy/brachytherapy, or bypass surgery [2]. For resource-limited settings, however, a number of additional factors need to be considered before recommendations can be made. These involve economic considerations and resource availability. Furthermore, patients in low-resource settings presenting with malignant esophageal obstruction are often unfit for surgery due to presentation with advanced malignant disease as well as comorbidities such as HIV/AIDS and tuberculosis [3]. For such situations, self-expanding metal stents (SEMS) of the esophagus may provide a suitable palliative option [3, 4].

  Abstract Objective To create and validate an objective and reliable score to assess referral quality in gastroenterology. Design An observational multicentre study. Setting and participants 25 gastroenterologists participated in selecting variables for a Thirty Point Score (TPS) for quality assessment of referrals to gastroenterology specialist healthcare for 9 common indications. From May to September 2014, 7 hospitals from the South-Eastern Norway Regional Health Authority participated in collecting and scoring 327 referrals to a gastroenterologist. Main outcome measure Correlation between the TPS and a visual analogue scale (VAS) for referral quality. Results The 327 referrals had an average TPS of 13.2 (range 1–25) and an average VAS of 4.7 (range 0.2–9.5). The reliability of the score was excellent, with an intra-rater intraclass correlation coefficient (ICC) of 0.87 and inter-rater ICC of 0.91. The overall correlation between the TPS and the VAS was moderate (r=0.42), and ranged from fair to substantial for the various indications. Mean agreement was good (ICC=0.47, 95% CI (0.34 to 0.57)), ranging from poor to good. Conclusions The TPS is reliable, objective and shows good agreement with the subjective VAS. The score may be a useful tool for assessing referral quality in gastroenterology, particularly important when evaluating the effect of interventions to improve referral quality.
