ABSTRACT
Background and study aims: Motorized spiral enteroscopy is proven to be effective in antegrade and retrograde enteroscopy. Nevertheless, little is known about its use in less common indications. The aim of this study was to identify new indications for the motorized spiral enteroscope. Methods: Monocentric retrospective analysis of 115 patients who underwent enteroscopy using PSF-1 motorized spiral enteroscope between January 2020 and December 2022. Results: A total of 115 patients underwent PSF-1 enteroscopy. 44 (38%) were antegrade procedures and 24 (21%) were retrograde procedures in patients with normal gastrointestinal anatomy with conventional enteroscopy indications. The remaining 47 (41%) patients underwent PSF-1 procedures for secondary less conventional indications: n=25 (22%) enteroscopy-assisted ERCP, n=8 (7%) endoscopy of the excluded stomach after Roux-en-Y gastric bypass, n=7 (6%) retrograde enteroscopy after previous incomplete conventional colonoscopy and n=7 (6%) antegrade panenteroscopy of the entire small bowel. In this group of secondary indications, technical success rate was significantly lower (72.5%) as compared to technical success rates in the conventional groups (98-100%, p<0.001 Chi-square). Minor adverse events occurred in 17/115 patients (15%), all treated conservatively (AGREE I and II). Conclusion: This study demonstrates the capabilities of PSF-1 motorized spiral enteroscope for secondary indications. PSF-1 is useful to complete colonoscopy in case of long redundant colon, to reach the excluded stomach after Roux-en-Y gastric bypass, to perform unidirectional pan-enteroscopy and to perform ERCP in patients with surgically altered anatomy. However, technical success rates are lower as compared to conventional antegrade and retrograde enteroscopy procedures, with only minor adverse events.

We present the case of a 59-years-old woman with a history of abdominal pain and iron-deficiency anemia. Upper and lower gastrointestinal endoscopy turned out negative and further investigation with wireless videocapsule showed an inflammatory stricture in the middle of the small bowel with retention of the videocapsule. Treatment with budesonide was initiated and allowed the spontaneous evacuation of the videocapsule. Retrograde motorized spiral enteroscopy was performed and confirmed an ulcerative stricture 60 cm proximal to the ileocaecal valve. Clinical, iconographic, endoscopic and histological results were compatible with a rare entity described as cryptogenic multifocal ulcerative stenosing enteritis (CMUSE). After the diagnosis budesonide was replaced by azathioprine 100 mg/d as an immunosuppressor. However, azathioprine induced mild pancreatitis and a second course of budesonide was started again. Clinical evolution was favorable.

Background and study aims: Gastrointestinal endoscopic procedures have evolved significantly in the last sixty years revolutionising the approach to the diagnostic and therapeutic spheres of medicine. Despite the advantages of using natural orifices to the bowel, adverse events (AE) may occur following endoscopy. Systematic AE registration is an objective in every realm of quality medicine. Despite the obvious advantage as a quality indicator, tracking endoscopy-related AE is not evident. The current study aimed at tracking all AE of all endoscopic procedures during a 3-month period. The three methods used were voluntary reporting by the endoscopist and by the patient in parallel with retrospective data analysis of patients' electronic medical records to allow capture of all AE and comparison of the three methods. Patients and methods: During a 3-month period endoscopists and patients were requested to report any possible AE. At the end of the period, a systematic review of all patient files was performed to track all AE related to the endoscopic procedure or the endoscopyrelated anaesthesia. In total 2668 endoscopic procedures were reviewed. Results: The total AE rate was 1.95%. Only half (51.9%) of all AE were voluntarily reported by endoscopists, the other half were extracted from the electronic medical record. There were no patient-reported AE. Although the majority (66.7%) of unreported AE were mild, these findings illustrate that voluntary AE reporting is unreliable. However, the retrospective tracking process proved to be difficult and time-consuming. Conclusions: The current study highlighted that systematic registration of all endoscopy-related AE is feasible, but challenging because of multiple hurdles. More practical methods are warranted to obtain reliable and long-term data as part of endoscopy quality measures.

Background and study aims: Data on procedural outcome and quality of endoscopic retrograde cholangiopancreatography (ERCP) in Belgian practice are scarce. The aim of this study is to assess current status of ERCP-performance in Belgium. Methods: National multi-institutional survey (online questionnaire) among members of the Belgian Society of Gastrointestinal Endoscopy (BSGIE), conducted in the period June-August 2018. The RIZIV/INAMI provided real-life data on the total number of ERCPs performed in Belgium. Results: Forty-five responders completed the survey (for 43 centers performing ERCP), providing information for 8368 ERCPs performed in 45% (43/95) of institutions performing ERCP in Belgium. Fifty-eight percent of centers performed > 100 ERCPs/year and 7% of centers (n=3) performed < 50 ERCPs/year. According to the RIZIV/INAMI data, low case-volume centers are underrepresented in this survey. The most common ERCPindication was stone extraction (52%). 74% of endoscopists had more than 10 years of experience in performing ERCP. The majority of centers had their own written protocol (84%) for microbiological duodenoscope surveillance. Monitoring of cannulation rate and post-ERCP pancreatitis (PEP) was only performed in a minority of centers (30%). The majority of centers (76%) provided verbal informed consent relating to the ERCP-procedure ; a minority also requested a written informed consent (23%). 65% of centers systematically use NSAIDs for PEP prophylaxis. Conclusion: This is the first survey of ERCP performance in Belgium. There were wide variations in practice. Adherence to key performance measures and measurement and evaluation of ERCP performance in daily practice at center and endoscopist level are not uniformly widespread.

We report a case of a 67-years-old woman presenting a severe acute lymphocytic gastritis induced by pembrolizumab, an immune check point inhibitor (ICI). This gastritis was her third auto-immune adverse event after 5 years of treatment with pembrolizumab, it was metabolically active at the PET Scan and confirmed by analysis of the gastric biopsies. Pembrolizumab treatment cessation and high doses of corticosteroids completely normalized the stomach clinically, endoscopically and histologically. This patient was in complete remission of her metastatic melanoma. Therefore, pembrolizumab therapy was not restarted and the patient is still in remission 6 months later. This strategy is supported by recent publications describing a relapse rate inferior to 10% in patients in complete remission after 2 years of immunotherapy. Particularities of this case are: rareness of this adverse event, late onset after introduction of pembrolizumab, evocative PET scan image, specific endoscopic aspect and histology. In addition, the favorable oncologic evolution of the patient after treatment cessation confirms the prolonged remission after immunotherapy.

BACKGROUND AND AIMS: With the first wave of the COVID-19 pandemic declining, activities in the gastrointestinal clinic are being recommenced after a period of stringent measures. Since a second COVID-19 wave is not entirely ruled out health care professionals might remain faced with the need to perform endoscopic procedures in patients with a confirmed positive or unknown COVID-19 status. With this report we aim to provide a practical relevant overview of preparation and protective measures for gastroenterologists based on the currently available guidelines and our local experience and results of a national Belgian survey, to guarantee a fast recall of an adequate infection prevention if COVID-19 reoccurs. METHODS: From the 23rd of March 2020 and the 13th of May 2020 we performed a Pubmed, Embase and Medline search, resulting in 37 papers on COVID-19 and endoscopy. Additionally, we combined these data with data acquired from the national BSGIE survey amongst Belgian gastroenterologists. RESULTS: Based on 72 completed surveys in both university and non-university hospitals, the results show (1) a dramatic (<20%) or substantial (<50%) decrease of normal daily endoscopy in 74% and 22% of the units respectively, (2) a difference in screening and protective measures between university and non-university hospitals. These findings were subsequently compared with the current guidelines. CONCLUSION: Based on new data from the BSGIE survey and current guidelines we tried to realistically represent the current COVID-19 trends in protective measures, screening and indications for endoscopy and to provide a practical overview as preparation for a possible second wave.

BACKGROUND: The natural history of ulcerative colitis (UC) is unpredictable. Factors associated with the need for different types of step-up therapy in UC patients failing on 5-aminosalicylic acid (5-ASA) or corticosteroids are understudied. AIMS: Describe step-up therapy in patients with UC the first year after failing on 5-ASA or corticosteroids. METHODS: A Belgian, multi-center, prospective, non-interventional observational study comprising adult UC patients failing on 5-ASA or corticosteroids and naïve to immunomodulators/ biologicals. During a 12 months follow-up, patient characteristics, demography, medical therapy, biomarkers, therapy adherence and quality of life (QoL) were assessed. RESULTS: After 1 year, 35% of the patients were on biological therapy. Use of anti-TNF differed depending on baseline treatment: corticosteroid-refractory patients (55.8%), 5-ASA refractory (20.0%), and corticosteroid-dependent (16.0%) patients (p<0.001). The decision to start a line of therapy was based on the Mayo combined severity but not on biomarkers like faecal calprotectin, haemoglobin, CRP, albumin, platelets, and number of extraintestinal manifestations. At year 1, 84.2% of the patients had only mild UC or remission and a significant improvement of fatigue (p=0.004) and IBDQ scores (p<0.001) were observed implying an improved QoL. CONCLUSION: Treatment step-up, based on clinical scores in immunomodulatory and anti-TNF naïve patients with UC, provides good clinical outcomes and QoL.

The history of Acta Gastro-Enterologica Belgica is long, rich and cloudy. There is no centralised archive available. However, all currently active gastroenterologists in Belgium have been trained with the journal, have published abstracts or manuscripts in it, or at least know of its existence. Whereas it started as a national society's journal in 1933, it has grown to a competitive international journal with Impact Factor. We felt the need to reconstruct the journal's long history, since this was never done before. This review tried to highlight some of the important milestones, without claiming to be complete. Looking back helps to better foresee and anticipate the future.

BACKGROUND AND STUDY AIMS: Anti-TNF monoclonal antibodies are a cornerstone in the treatment of Crohn's disease. Prospective data on switching from the subcutaneous and human adalimumab (ADM) to the intravenous and chimeric infliximab (IFX) are scarce. PATIENTS AND METHODS: In this prospective, observational, multicentre cohort study we included 21 patients with loss of response to ADM despite at least 4 consecutive weekly injections. Clinical response (CDAI drop≥70 points) and remission (CDAI≤150) were assessed after switching from ADM to IFX after 10 weeks, 6 and 12 months. Predictive factors of response/remission, the need for therapy intensification, discontinuation and safety were investigated. RESULTS: Short-term response and remission (10 weeks) were seen in 57% and 48% respectively. Mid- and long-term clinical response and remission were achieved in 40% and 25% after 6 months and in 45% and 20% after 12 months respectively. At 12 months, 81% still were on IFX. IFX therapy intensification was needed in half of the patients at 6 months and three quarter of patients at 12 months. Undetectable ADM trough levels (despite weekly injections) were a predictive factor for short-term response and remission to IFX. About half of the patients with response at week 10 maintained response at 6 and 12 months. CONCLUSIONS: Switching from ADM to IFX can be efficacious in patients with loss of response, in particular in case of undetectable ADM trough levels. The majority of patients however will need IFX therapy intensification during their first year of treatment.

Endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II patients is challenging and different endoscopes can be used. We retrospectively analysed 67 ERCP procedures in 38 Billroth II patients focussing on endoscope type and respective technical success and adverse event rate. 33 (49.2 %) ERCPs were performed using a duodenoscope, 87.9 % were successful and 3 were completed with the single-balloon enteroscope. 28 (41.8 %) ERCPs were performed with the single-balloon enteroscope, 82.1 % were successful and 2 were completed with a paediatric colonoscope. For 6 (9.0 %) ERCPs a paediatric colonoscope was used but only 3 (50.0 %) were successful. Overall technical success rate was 82.1 % without difference between the success rate of the duodenoscope and the single-balloon enteroscope. Overall adverse event rate was 10.5 %: 6.1 % duodenoscope,10.7 % single-balloon enteroscope, 33.3 % paediatric colonoscope. The duodenoscope allowed all conventional ERCP procedures, whereas the singleballoon enteroscope required dedicated ERCP catheters and did not allow metallic stent placement. However, the single-balloon enteroscope facilitated access to the papilla and sphincteroplasty allowed direct cholangioscopy. ERCP indications were bile duct stones (53.7 %), cholangitis (20.9 %), chronic pancreatitis (20.9 %), pancreatic cancer (1.5 %) and liver transplantation (3%). Therapeutic ERCP success rate is high in patients with Billroth II gastrectomy using either a conventional duodenoscope or the single-balloon enteroscope, with an acceptable and comparable adverse event rate. The choice of endoscope may depend on local experience, post-operative anatomy and therapeutic indication.

BACKGROUND AND STUDY AIMS: Small bowel ulceration poses a limited, but difficult differential diagnosis. The most common causes are Crohn's disease (CD), NSAID-associated enteritis, lymphoma, cytomegaly virus infection and tuberculosis. A less known and relatively novel differential diagnosis is cryptogenic multifocal ulcerative stenosing enteritis (CMUSE). PATIENTS AND METHODS: ive patients referred for balloon-assisted enteroscopy for various reasons showed endoscopic features of CMUSE. These findings and, when available, medical imaging were reviewed in order to increase general knowledge on CMUSE. RESULTS: Five patients, 3 males and 2 females, with a mean age of 39±5 years, underwent balloon-assisted enteroscopy. Typical short, circular, ulcerative stenoses were detected in the jejunum in 2 and in the ileum in 3 patients. The number of stenoses ranged from 1 to 7 per patient. Histopathology revealed nonspecific granulocyte inflammation without specific CD findings. Stenoses were often missed on pre-enteroscopy CT or MRI enteroclysis due to their short length. Treatment consisted of endoscopic balloon dilation in 3, corticosteroids in 3, azathioprine in 1 and anti-TNFα biologicals in 3 patients. 3 patients needed additional surgery because of ongoing symptomatic small bowel stenosis or retained wireless videocapsule. CONCLUSION: In patients with short, ulcerative small intestinal stenoses CMUSE is an important but often neglected differential diagnosis. The pathophysiology and relationship to CD are subject of ongoing debate, but specific endoscopic characteristics, different histopathological findings and lack of clear abnormalities on CT or MRI enterography suggest that CMUSE is a distinct albeit rare chronic inflammatory bowel disease.

Ulcerative colitis and Crohn's diseases are relapsing longstanding inflammatory bowel diseases, associated with an increased risk of developing colorectal cancer. Continuous surveillance is necessary to detect the preneoplastic lesions in an early stage. New endoscopic techniques have improved the diagnostic accuracy and have resulted in a new and more simplified classification system of the dysplastic lesions in the bowel. Histopathologically these lesions are very heterogenous, consisting of adenomatous, villous and the more recently discovered serrated dysplasia. Its diagnosis may be hampered by the inflamed mucosa, resulting in a high interobserver variability in the categories of indefinite for dysplasia and low-grade dysplasia. Therefore the ECCO guidelines recommend to confirm the diagnosis of dysplasia by a pathologist with expertise in gastrointestinal pathology. In this article we give an overview of colitis-associated dysplasia from the point of view of the endoscopist and the pathologist.

Colonoscopy is an important endoscopic examination for the diagnosis and treatment of pathological conditions of the colon, like polyps and colorectal cancer. However, several factors determine the quality of colonoscopy and thus the quality of polyp and colorectal cancer detection. The Flemish Society of Gastroenterology (VVGE) performed a voluntary on-line registry among its members to identify quality of colonoscopy in Flanders, Belgium. 64 gastroenterologists voluntarily registered 4276 consecutive colonoscopies performed during a 3 month study period. Colonoscopy quality indicators were prospectively collected and analysed. Results showed a low voluntary participation rate (17%), acceptable overall adenoma detection rate of 20,5% and colorectal cancer interval rate of 5,4%. Complications were low (perforation 0,1% and major bleeding 1,5%). The current study showed that in Flanders, Belgium on-line registration of colonoscopy quality indicators is feasible and that quality of colonoscopy in daily practice meets the expectations of (inter)national guidelines. However, further improvement of the registry and an open debate on the quality control of colonoscopy in Flanders is warranted (Belgian Registry B30020096548).
