Background: Little is known about how to most effectively deliver relevant information to patients scheduled for endoscopy.Methods: To assess the effects of combined written and oral information, compared with oral information alone on the quality of information before endoscopy and the level of anxiety. We designed a prospective study in two Swiss teaching hospitals which enrolled consecutive patients scheduled for endoscopy over a three-month period. Patients were randomized either to receiving, along with the appointment notice, an explanatory leaflet about the upcoming examination, or to oral information delivered by each patient's doctor. Evaluation of quality of information was rated on scales between 0 (none received) and 5 (excellent). The analysis of outcome variables was performed on the basis of intention to treat-analysis. Multivariate analysis of predictors of information scores was performed by linear regression analysis.Results: Of 718 eligible patients 577 (80%) returned their questionnaire. Patients who received written leaflets (N = 278) rated the quality of information they received higher than those informed verbally (N = 299), for all 8 quality-of-information items. Differences were significant regarding information about the risks of the procedure (3.24 versus 2.26, p < 0.001), how to prepare for the procedure (3.56 versus 3.23, p = 0.036), what to expect after the procedure (2.99 versus 2.59, p < 0.001), and the 8 quality-of-information items (3.35 versus 3.02, p = 0.002). The two groups reported similar levels of anxiety before procedure (p = 0.66), pain during procedure (p = 0.20), tolerability throughout the procedure (p = 0.76), problems after the procedure (p = 0.22), and overall rating of the procedure between poor and excellent (p = 0.82).Conclusion: Written information led to more favourable assessments of the quality of information and had no impact on patient anxiety nor on the overall assessment of the endoscopy. Because structured and comprehensive written information is perceived as beneficial by patients, gastroenterologists should clearly explain to their patients the risks, benefits and alternatives of endoscopic procedures.Trial Registration: Current Controlled trial number: ISRCTN34382782.

The development of liver fibrosis is the consequence of histological remodeling of the liver parenchyma, reflecting chronic inflammatory liver disease or hepatocyte necrosis. These tissue modifications result in structural changes to the extracellular matrix, predisposing to progression to cirrhosis and hepatocellular carcinoma, whatever the underlying etiology. Recent data demonstrate the potential benefits of screening for hepatic fibrosis, in particular in order to detect and treat the cause of the underlying liver disease as early as possible, which could ultimately lead to the many known complications in cirrhotic patients. Early identification of the population at risk of hepatic fibrosis should precede screening, which may be initiated in the primary care physician's office and continued at a later stage by the specialist., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Gastroparesis is a pathology associating upper digestive symptoms, such as nausea and vomiting, with impaired gastric emptying in the absence of mechanical gastric or duodenal obstruction. It has a major impact on patients' quality of life, can lead to undernutrition, and -increases overall mortality. Several schools of thought converge on the hypothesis of a clinico--pathological spectrum of gastric neuro-muscular dysfunction encompassing gastroparesis and functional dyspepsia, in particular the subtype known as "postprandial distress syndrome". Its management includes non--pharmacological interventions, such as hygienic--dietary measures, pharmacological interventions using prokinetic, antiemetic or neuromodulatory treatments, and endoscopic interventions., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Acute diarrheal disease is a frequent primary care reason for consultation, leading to direct and indirect health costs in high-income countries. Most patients presenting with acute diarrhea will have a favorable clinical course with just a symptomatic treatment. The challenge for the general practitioner is to identify the patients who need paraclinical exams and/or antibiotics. Molecular identification of pathogens in stool samples has developed over the past years and presents both advantages and limitations. Because of increasing microbial resistance to quinolones in Campylobacter and Shigella strains, azithromycin is now the first choice for an empiric antimicrobial therapy. This article will discuss these latest developments in the management of acute diarrhea in the primary care setting., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article

Preneoplastic lesions of the esophagus and stomach are cellular abnormalities that have the potential to develop into cancer over time. They are detected during endoscopy and can be classified according to their specific cellular characteristics. Their treatment depends on the severity of the lesion and the individual factors of each patient. Treatment options may include regular endoscopic monitoring, treatment to reduce the risk of progression to cancer (anti-reflux therapy, antibiotics for H. pylori eradication), or endoscopic removal of the lesion. It is important to discuss any concerns about these lesions with a gastroenterologist and to follow recommendations for proper screening and treatment., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: Duodenal defects are complex clinical situations, and their management is challenging and associated with high mortality. Besides surgery, endoscopic treatment options exist, but the size and location of the perforation can limit their application. We present a retrospective study, demonstrating a successful application of endoscopic vacuum therapy (EVT) for duodenal leaks., Methods: We performed a retrospective study of all patients who underwent EVT for duodenal perforations between 2016 and 2021 at two tertiary centers. We analyzed demographic and clinical patient characteristics, surgical outcomes, leak characteristics, sponge-related complications, and success rate., Results: Indications for treatment with EVT in the duodenum consisted of leak after duodenal suture of a perforated ulcer (n = 4), iatrogenic perforation after endoscopic resection (n = 2), iatrogenic perforation during surgery (n = 2), and anastomotic leak after upper gastrointestinal surgery (n = 2). EVT was used as a first-line treatment in seven patients and as a second-line treatment in three patients. EVT was successfully applied in all interventions (n = 10, 100%). Overall, EVT lead to definitive closure of the defects in eight out of ten patients (80%). No severe EVT-related adverse events occurred., Conclusion: EVT is safe and technically feasible, so it emerges as a promising endoscopic treatment option for duodenal leaks. However, multidisciplinary collaboration and management are important to reduce the occurrence of postoperative complications, and to improve recovery rates., (© 2022. The Author(s).)

Autoimmune pancreatitis (AIP) is a type of immune-mediated pancreatitis subdivided into two subtypes, type 1 and type 2 AIP. Furthermore, type 1 AIP is considered to be the pancreatic manifestation of the immunoglobulin G4 (IgG4)-related disease. Nowadays, AIP is increasingly researched and recognized, although its diagnosis represents a challenge for several reasons: False positive ultrasound-guided cytological samples for a neoplastic process, difficult to interpret levels of IgG4, the absence of biological markers to diagnose type 2 AIP, and the challenging clinical identification of atypical forms. Furthermore, 60% and 78% of type 1 and type 2 AIP, respectively, are retrospectively diagnosed on surgical specimens of resected pancreas for suspected cancer. As distinguishing AIP from pancreatic ductal adenocarcinoma can be challenging, obtaining a definitive diagnosis can therefore prove difficult, since endoscopic ultrasound fine-needle aspiration or biopsy of the pancreas are suboptimal. This paper focuses on recent innovations in the management of AIP with regard to the use of artificial intelligence, new serum markers, and new therapeutic approaches, while it also outlines the current management recommendations. A better knowledge of AIP can reduce the recourse to surgery and avoid its overuse, although such an approach requires close collaboration between gastroenterologists, surgeons and radiologists. Better knowledge on AIP and IgG4-related disease remains necessary to diagnose and manage patients., Competing Interests: Conflict-of-interest statement: All the authors report having no relevant conflicts of interest for this article., (©The Author(s) 2022.

Objective: Despite international guidelines recommendations to use mortality as a quality criterion for gastrointestinal (GI) procedures, recent studies reporting these data are lacking. Our objective was to report death causes and rate following GI endoscopies in a tertiary university hospital., Design: We retrospectively reviewed all GI procedures made between January 2017 and December 2019 in our tertiary hospital in Switzerland. Data from patients who died within 30 days of the procedure were recorded., Results: Of 18 233 procedures, 251 patients died within 30 days following 345 (1.89%) procedures (244/9180 gastroscopies, 53/5826 colonoscopies, 23/2119 endoscopic ultrasound, 19/911 endoscopic retrograde cholangiopancreatography, 6/197 percutaneous endoscopic gastrostomies). Median age was 70 years (IQR 61-79) and 173/251 (68.92%) were male. Median Charlson Comorbidity Index was 5 (IQR 3-7), and 305/345 procedures (88.4%) were undertaken on patients with an ASA score ≥3. Most frequent indications were suspected GI bleeding (162/345; 46.96%) and suspected cancer or tumourous staging (50/345; 14.49%). Major causes of death were oncological progression (72/251; 28.68%), cardiopulmonary failure or cardiac arrest of unkown origin (62/251; 24,7%) and liver failure (20/251; 7.96%). No deaths were caused by complications such as perforation or bleeding., Conclusions: Progression of malignancies unrelated to the procedure was the leading cause of short-term death following a GI procedure. After improvements in periprocedural care in the last decades, we should focus on patient selection in this era of new oncological and intensive care therapies. Death rate as a quality criterion is subject to caution as it depends on indication, setting and risk benefit ratio., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Endoscopic submucosal dissection (ESD) is a mini-invasive technique allowing to resect superficial lesions of the digestive tract and maintaining organ function. High technical expertise is required as well as a network approach with referring physicians, pathologists, radiologists, surgeons and oncologists. Rigorous selection of cases as well as endoscopic management of potential complications (hemorrhage, perforation) is mandatory. Therefore, ESD should preferably be performed in expert centers with high volumes of cases, in order to maintain competency and offer optimal patient's management. Most frequent indications in the Western world are early cancers of the esophagus, stomach and colon as well as non-non-lifting polyps and gastrointestinal stromal tumors (GIST)., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Pancreatic cysts (PC) are common and often discovered incidentally. The distinction between PC is essential, because of the potential malignancy of some lesions requiring surgical resection. The clinical orientation will depend on the clinical history and the radiological characteristics. Indeed, in front of all PCs, it is essential to characterize them using cross-sectional imaging (MRI) in order to highlight the worrisome features requiring further examinations by endoscopic ultrasonography and fine needle aspiration of the cysts to guide the diagnosis. Referral to an expert center will allow to propose to each patient an adequate approach: surgical resection, surveillance according to the recommendations or therapeutic abstention., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: Reshaping the tumor microenvironment by novel immunotherapies represents a key strategy to improve cancer treatment. Nevertheless, responsiveness to these treatments is often correlated with the extent of T cell infiltration at the tumor site. Remarkably, microsatellite stable rectal cancer is characterized by poor T cell infiltration and, therefore, does not respond to immune checkpoint blockade. To date, the only available curative option for these patients relies on extensive surgery. With the aim to broaden the application of promising immunotherapies, it is necessary to develop alternative approaches to promote T cell infiltration into the tumor microenvironment of these tumors. In this regard, recent evidence shows that radiotherapy has profound immunostimulatory effects, hinting at the possibility of combining it with immunotherapy. The combination of long-course chemoradiotherapy and immune checkpoint inhibition was recently shown to be safe and yielded promising results in rectal cancer, however short-course radiotherapy and immune checkpoint inhibition have never been tested in these tumors., Methods: Our clinical trial investigates the clinical and biological impact of combining pembrolizumab with short-course radiotherapy in the neo-adjuvant treatment of localized rectal cancer. This phase II non-randomized study will recruit 25 patients who will receive short-course preoperative radiotherapy (5 Gy × 5 days) and four injections of pembrolizumab starting on the same day and on weeks 4, 7 and 10. Radical surgery will be performed three weeks after the last pembrolizumab injection. Our clinical trial includes an extensive translational research program involving the transcriptomic and proteomic analysis of tumor and blood samples throughout the course of the treatment., Discussion: Our study is the first clinical trial to combine short-course radiotherapy and immune checkpoint inhibition in rectal cancer, which could potentially result in a major breakthrough in the treatment of this cancer. Additionally, the translational research program will offer insights into immunological changes within the tumor and blood and their correlation with patient outcome. Taken together, our work will help optimizing future treatment combinations and, possibly, better selecting patients., Trial Registration: This study was registered with www., Clinicaltrial: gov : NCT04109755 .

Our objective was to describe the etiologies of acute colitis and to identify patients who require diagnostic endoscopy. Patients with symptoms of gastrointestinal infection and colonic inflammation on CT were prospectively included. Those immunosuppressed, with history of colorectal cancer or inflammatory bowel disease (IBD), were excluded. Microbiological analysis of the feces was performed using PCR assays BD-Max and FilmArray (GI panel,) and fecal cultures. Fecal calprotectin was determined. Patients with negative BD-Max underwent colonoscopy. One hundred and seventy-nine patients were included. BD-Max was positive in 93 patients (52%) and FilmArray in 108 patients (60.3%). Patients with infectious colitis (n = 103, 57.5%) were positive for Campylobacter spp. (n = 57, 55.3%), Escherichia coli spp. (n = 8, 7.8%), Clostridioides difficile (n = 23, 22.3%), Salmonella spp. (n = 9, 8.7%), viruses (n = 7, 6.8%), Shigella spp. (n = 6, 5.8%), Entamoeba histolytica (n = 2, 1.9%) and others (n = 4, 3.9%). Eighty-six patients underwent colonoscopy, which was compatible with ischemic colitis in 18 patients (10.1%) and IBD in 4 patients (2.2%). Fecal calprotectin was elevated in all patients, with a mean concentration of 1922.1 ± 2895.6 μg/g, and was the highest in patients with IBD (8511 ± 9438 μg/g, p < 0.001). After exclusion of patients with infectious etiology, a fecal calprotectin > 625 μg/g allowed identifying patients with IBD with an area under ROC curve of 85.1%. To conclude, computed tomography-proven colitis was of infectious etiology in 57.5% of patients. The main pathogens identified were Campylobacter spp. (55.3%), Clostridioides difficile (22.3%) and Salmonella spp. (8.7%). Ischemic colitis (10.1%) and IBD (2.2%) were seldom represented. No colorectal cancer was found., (© 2022. The Author(s).)

Among the recent advances in gastroenterology, colonoscopy with artificial intelligence is associated with a better quality of screening. In refractory UC, Ozanimod seems to be an interesting salvage treatment, which still needs to be validated by Swissmedic. Among the direct-acting anticoagulants, Rivaroxaban is more frequently associated with GI bleeding. The classification of oesophageal motor disorders has been recently revised, the Chicago v4.0 classification should be applied in diagnostic management. The use of Semaglutide seems to show very promising results in the management of metabolic steatosis. SARS-CoV-2 infection can be complicated by biliary tract disease, which can progress to hepatocellular failure., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: PEG (percutaneous endoscopic gastrostomy) is a well established endoscopic procedure for enteral feeding. However, patients with a shorter life expectancy will not benefit from PEG tube placement. Furthermore, some specific evolving diseases will never benefit from PEG. The aim of the study focuses on short and long term mortality rates after PEG tube placement in a referral gastroenterology centre (Geneva University Hospital). 219 patients were enrolled in this study., Patients and Methods: All patients scheduled for a PEG procedure between January 2011 and December 2014 were included. Nine patient parameters were collected for further analysis as well as the main underlying disease requiring PEG tube placement. Patients were subsequently divided into 4 groups according to underlying disease: Group 1) swallowing disorders of neurologic origin; Group 2) swallowing disorders associated with upper digestive tract neoplasia ; Group 3) nutritional support for a non GI reason ; Group 4) Other., Results: 219 patients had undergone a PEG tube placement. 33 patients died within 60 days after the procedure. After one year, 71 patients died. Global survival was 870 days. The nutritional support group had the better survival rate with 1276 days compared to the swallowing groups and others. The multivariate analysis has highlighted the underlying disease as the only associated parameter with short and long term mortality., Conclusions: PEG tube placement is associated with high short and long term mortality depending on the underlying disease. We outlined the potential role of PEG tube insertion as a supportive transient approach for nutritional support., Competing Interests: The authors declare that they have no conflict of interest, (© Acta Gastro-Enterologica Belgica.)

The video capsule endoscopy allows the exploration or the unreachable part of the small intestine by a standard bidirectional endoscopy. It requires a specific device and a bowel preparation but it's an outpatient examination with an acceptable tolerance of the patients. There are several indications including an obscure gastrointestinal bleeding, an iron deficit anemia, Crohn's disease extension and phenotype, hereditary polyposis and coeliac disease. It doesn't include therapeutic options itself requiring an assisted enteroscopy if any lesion is detected. The use of a dissolvable Patency Capsule lowers the risk of a mechanical intestinal occlusion if a stenosis is suspected. The colon capsule endoscopy is very promising for the colorectal cancer screening and follow-up of inflammatory bowel diseases but it's not currently validated nor recommended., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Gastrointestinal cancers occur in a total of eight different locations, each of them with a different standard of care. This article is not an exhaustive review of what has been published in 2020. We have concentrated on the thirteen phase III randomized studies that are practice-changing. All these studies are oral presentations which have been given in one of the four major oncology congresses, namely American Society of Clinical Oncology (ASCO), ASCO gastrointestinal (GI), European Society of Medical Oncology (ESMO) and ESMO-GI. We provide a concise view of these major trials and their main outcomes, and put these results into context., Competing Interests: Conflict-of-interest statement: No conflict of interest., (©The Author(s) 2021.

Background & Aims: There are conflicting data regarding the epidemiology of hepatocellular carcinoma (HCC) arising in the context of non-alcoholic and metabolic-associated fatty liver disease (NAFLD and MAFLD). We aimed to examine the changing contribution of NAFLD and MAFLD, stratified by sex, in a well-defined geographical area and highly characterised HCC population between 1990 and 2014., Methods: We identified all patients with HCC resident in the canton of Geneva, Switzerland, diagnosed between 1990 and 2014 from the prospective Geneva Cancer Registry and assessed aetiology-specific age-standardised incidence. NAFLD-HCC was diagnosed when other causes of liver disease were excluded in cases with type 2 diabetes, metabolic syndrome, or obesity. Criteria for MAFLD included one or more of the following criteria: overweight/obesity, presence of type 2 diabetes mellitus, or evidence of metabolic dysregulation., Results: A total of 76/920 (8.3%) of patients were diagnosed with NAFLD-HCC in the canton of Geneva between 1990 and 2014. Between the time periods 1990-1994 and 2010-2014, there was a significant increase in HCC incidence in women (standardised incidence ratio [SIR] 1.83, 95% CI 1.08-3.13, p  = 0.026) but not in men (SIR 1.10, 95% CI 0.85-1.43, p  = 0.468). In the same timeframe, the proportion of NAFLD-HCC increased more in women (0-29%, p  = 0.037) than in men (2-12%, p  = 0.010) while the proportion of MAFLD increased from 21% to 68% in both sexes and from 7% to 67% in women ( p <0.001). From 2000-2004 to 2010-2014, the SIR of NAFLD-HCC increased to 1.92 (95% CI 0.77-5.08) for men and 12.7 (95% CI 1.63-545) in women, whereas it decreased or remained stable for other major aetiologies of HCC., Conclusions: In a populational cohort spanning 25 years, the burden of NAFLD and MAFLD associated HCCs increased significantly, driving an increase in HCC incidence, particularly in women., Lay Summary: Hepatocellular carcinoma (HCC) is the most common type of liver cancer, increasingly arising in patients with liver disease caused by metabolic syndrome, termed non-alcoholic fatty liver disease (NAFLD) or metabolic-associated fatty liver disease (MAFLD). We assessed all patients with HCC between 1990 and 2014 in the canton of Geneva (western Switzerland) and found an increase in all HCC cases in this timeframe, particularly in women. In addition, we found that HCC caused by NAFLD or MAFLD significantly increased over the years, particularly in women, possibly driving the increase in overall HCC cases., Competing Interests: The authors declare no conflicts of interest that pertain to this work.

Acute alcoholic microvesicular steatosis (MIC) may complicate heavy alcohol intake and present as alcoholic hepatitis (AH) syndrome. However, detailed clinical, biological, and histologic data associated with MIC are scarce. We compared the clinical presentation, histologic features, and hepatic transcriptomic of patients presenting with AH due to either MIC or severe alcoholic steatohepatitis (ASH). In this case-control study, patients who drank heavily (>100 g/day) with the AH syndrome were included either in the MIC group (>50% severe microvesicular steatosis, no inflammation) or in the severe ASH group (polynuclear neutrophil infiltration, macrosteatosis, ballooned hepatocytes). All patients received standard supportive care plus steroids for those with severe ASH and were followed up for 3 months. Whole-liver transcriptome profiling was performed on liver snap-frozen biopsies. Compared to ASH (n = 24, mean age 49.3 years), patients in the MIC group (n = 12, mean age 49.1 years) had a higher reported alcohol intake ( P  < 0.01), lower Model for End-Stage Liver Disease score ( P  < 0.05), lower hepatic venous pressure gradient ( P  < 0.01), higher alanine aminotransferase ( P  < 0.02) and gamma-glutamyltransferase ( P  < 0.001), higher triglycerides ( P  < 0.001) and total cholesterol ( P  < 0.002), but similar bilirubin levels ( P  = 0.54). At histology, patients with MIC had a lower fibrotic stage compared to those with ASH ( P  < 0.001). A higher density of megamitochondria was seen in MIC compared to ASH ( P  < 0.05). During follow-up, death or transplantation occurred in 4/12 (33%) patients with MIC and 7/24 (29%) patients with severe ASH. Differential hepatic gene expression in MIC compared to ASH included down-regulation of genes related to inflammation and fibrosis and up-regulation of genes involved in lipid metabolism and mitochondrial function. Conclusion: MIC is an acute, noninflammatory, potentially severe alcoholic liver injury mimicking ASH, is associated with a lower fibrosis stage, and has a distinct gene expression profile., (© 2021 The Authors.

Bile holds biomarkers of malignant biliary strictures (MBS) but is unsuited for automated analyzers used in routine diagnostic laboratories. Selected reaction monitoring (SRM) is a flexible high-throughput analytical approach based on targeted mass spectrometry (MS) already implemented in clinical settings. We tested the hypothesis that SRM could be used to quantify cancer biomarkers in human bile. An SRM-based assay was developed to simultaneously quantify up to 37 peptides from 13 bile proteins in a developmental cohort of 15 patients (MBS, n = 8; benign biliary stricture or obstruction (BBS), n = 7). The most reliable biomarkers were then absolutely quantified by SRM in a verification cohort of 67 patients (MBS, n = 37; BBS, n = 30). The diagnostic performances of single and combined biomarkers were assessed. In the developmental cohort, SRM-based analysis revealed six protein biomarkers with significantly higher peptide ratios (endogenous vs. standard) in bile from MBS vs. BBS. In the verification cohort, five of these biomarkers proved good diagnostic ability (individual receiver operating characteristic-area under the receiver operating characteristic curve (ROC-AUC) up to 0.889, accuracies from 67.8% to 83.1%). Combining bile biomarkers and serum CA19-9 in 2 panels allowed differentiating MBS from BBS with up to 0.929 ROC-AUC and 89.8% accuracy. In this study, a newly developed SRM-based assay proved able to simultaneously quantify multiple biomarkers in bile samples. The combination of bile biomarkers with serum CA19-9 was highly accurate for the diagnosis of MBS. Liquid biopsy of bile based on targeted MS is eligible to support MBS diagnosis in clinical practice., (© 2020 The Authors.

Objective: Emergence of molecular methods to screen stools could provide a more complete picture of pathogens causing gastroenteritis, allowing to adequately treat patients whenever required but, so far, no aggregate data have been released. Our objective was to report pathogens identified in patients suffering from gastroenteritis using a multiplex molecular array., Design: Medline and Embase were searched for original publications reporting pathogens identified with FilmArray GI panel in patients suffering from gastroenteritis. Proportions of pathogens were extracted and pooled using a model with random effects., Results: Fourteen studies (17,815 patients) were included in the analysis. Among the 7,071 patients (39.7%) with positive FilmArray, identified pathogens were EPEC (27.5%), Clostridium difficile (19.3%), Norovirus (15.1%), EAEC (15%), Campylobacter spp (11.8%), Salmonella spp (8.1%), ETEC (7.3%), Rotavirus (7.3%), Sapovirus (7.1%), STEC (5.2%), Shigella/EIEC (4.9%), Giardia lamblia (4%), Adenovirus (3.8%), Cryptosporidium spp (3.8%), Astrovirus (2.8%), Yersinia enterocolitica (1.7%), Escherichia coli O157 (1.1%), Plesiomonas shigelloides (1.1%), Cyclospora cayetanensis (0.7%), Vibrio spp (0.5%), Vibrio cholerae (0.3%) and Entamoeba histolytica (0.3%). When considering only studies with control group (microbiological examination of the stools performed by other methods), FilmArray identified at least one pathogen in 48.2% of patients versus 16.7% when using comparative diagnostic methods., Conclusions: FilmArray GI panel was positive in 39.7% of patients suffering from gastroenteritis. This proportion has to be mitigated by the carriage rates of identified organisms. Ultimately, restricted ordering of molecular panels to those patients who might benefit from specific treatment could provide medical value by swift identification of the pathogen and more targeted therapy.

Foreign bodies ingestion is a common event, with a potential morbidity and mortality. In the majority of cases, the foreign bodies pass through the digestive tract without any complication. An endoscopy for removal of the foreign body is necessary in 10 to 20 % of cases and a surgical intervention is required in < 1 % of cases. In this article, we describe the clinical presentation, the potential complications, as well as the timing and endoscopic technics of foreign bodies retrieval, essentially based on the European Society of Gastrointestinal Endoscopy recommendations., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Esophageal cancer remains an oncological burden with a low survival rate. Multidisciplinary management is essential to offer an adjusted treatment to the patient general condition and the tumor stage. New minimally invasive surgical treatments help to reduce the surgical trauma and improve post-operative patient recovery. Oncological treatments have also evolved and definitive treatment by radio-chemotherapy can be proposed in specific cases., Competing Interests: Les auteurs n’ont aucun conflit d’intérêts en relation avec cet article.

Identification of disease-associated autoantibodies is of high importance. Their assessment could complement current diagnostic modalities and assist the clinical management of patients. We aimed at developing and validating high-throughput protein microarrays able to screen patients' sera to determine disease-specific autoantibody-signatures for pancreatic cancer (PDAC), chronic pancreatitis (CP), autoimmune pancreatitis and their subtypes (AIP-1 and AIP-2). In-house manufactured microarrays were used for autoantibody-profiling of IgG-enriched preoperative sera from PDAC-, CP-, AIP-1-, AIP-2-, other gastrointestinal disease (GID) patients and healthy controls. As a top-down strategy, three different fluorescence detection-based protein-microarrays were used: large with 6400, intermediate with 345, and small with 36 full-length human recombinant proteins. Large-scale analysis revealed 89 PDAC, 98 CP and 104 AIP immunogenic antigens. Narrowing the selection to 29 autoantigens using pooled sera first and individual sera afterwards allowed a discrimination of CP and AIP from PDAC. For validation, predictive models based on the identified antigens were generated which enabled discrimination between PDAC and AIP-1 or AIP-2 yielded high AUC values of 0.940 and 0.925, respectively. A new repertoire of autoantigens was identified and their assembly as a multiplex test will provide a fast and cost-effective tool for differential diagnosis of pancreatic diseases with high clinical relevance.

Background and Aims: Anticoagulant therapy has been recommended in patients with cirrhosis and portal vein thrombosis especially in candidates for liver transplantation. These patients are also likely to need variceal band ligation. This study aimed to assess the incidence of upper gastrointestinal bleeding after elective variceal band ligation in patients with cirrhosis receiving anticoagulant therapy for portal vein thrombosis., Methods: Patients with cirrhosis and nontumoral portal vein thrombosis treated with anticoagulant therapy undergoing elective variceal band ligation were retrospectively included. We recorded upper gastrointestinal bleeding events occurring within two weeks after variceal band ligation. Postvariceal band ligation bleeding was defined as active bleeding on at least one site of previous ligation at endoscopy., Results: Between 2014 and 2017, 32 patients with cirrhosis had scheduled variceal band ligations while on anticoagulant therapy [men 75%; median age 59 years; aetiology of cirrhosis: alcohol (50%), viral (34%), alcohol and viral (16%); and Child-Pugh score: A (31%), B (44%), and C (25%)]. Three (9%) patients presented postvariceal band ligation bleeding during the follow-up. None of these events led to haemorrhagic shock or death. Factors associated with postvariceal band ligation bleeding included variceal band ligation performed as secondary prophylaxis (P = 0.05) and previous decompensation of cirrhosis (P = 0.03)., Conclusion: In this small group of patients under anticoagulation therapy undergoing variceal band ligation, only a minority presented postendoscopic bleeding of minor importance. Nevertheless, particular attention should be paid to patients with previous decompensation of cirrhosis.

This article aims to review the most important innovations and updates in gastroenterology and hepatology in 2019. The role of ursodesoxycholic acid is questioned in cholestasis during pregnancy. Aspirin appears to prevent fibrotic lesions in NALFD. Tenofovir remains the gold standard in the treatment (TT) of HBV during pregnancy. The role of carvedilol is confirmed in the TT of portal hypertension. The risk of degeneration of TIPMP lesions suggests increased surveillance. Colonoscopy should be systematic after an episode of acute diverticulitis. The surveillance of celiac disease is specified. Tofacitinib is an effective molecule in ulcerative colitis but precautions are needed. Budesonide tablet is validated for the TT of eosinophilic esophagitis., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: Patients with periampullary tumors frequently undergo endoscopic biliary investigations and biliary drainage (BD) prior to surgery. Recent literature shows a shift of the biliary microbiome toward more resistant bacteria in patients having BD. This study aimed to evaluate the local microbiome and changes induced by BD and related antibiotic exposure and to consider the choice of antibiotic for peri-operative prophylaxis. Methods: A single-center retrospective cohort study included patients operated on for periampullary tumors between January 2013 and November 2017. All patients had intra-operative bile samples taken for culture and peri-operative antibiotic use as well as documentation of complications according to the Dindo-Clavien classification. Results: A total of 37 patients were included. All received pre-operative endoscopy, and 29 (78%) had BD preceded by administration of ceftriaxone or metronidazole. Intra-operative antibiotic prophylaxis consisted of cefuroxime (92%) or ceftriaxone (13%) combined with metronidazole (100%). Bacterial contamination of bile samples was more common in the BD group than in the no biliary drainage (NBD) group (93% vs 38%; p < 0.01). A shift was observed from bile containing mainly Escherichia coli and Streptococcus spp. toward Enterococcus faecalis (0 in the NBD group versus 44.8% in the BD group; p < 0.01), Enterococcus faecium (0 versus 23%; p = 0.3), and Candida albicans (0 versus 34.5%; p = 0.08). Post-operative antibiotic modifications were common. No difference was found regarding Dindo-Clavien complications, post-operative stay, or antibiotic use in the two groups, although one patient in the NBD group who had pre-operative biliary endoscopy with antibiotic prophylaxis developed a fatal septic clot caused by Escherichia coli resistant to cefuroxime. Conclusions: We observed a significant change toward colonization by enterococci and fungi in the microbiome of patients who had pre-operative biliary investigations or drainage with antibiotic prophylaxis. These findings indicate that bile samples should be obtained systematically during surgery for periampullary tumors to guide any post-operative antibiotic therapy and peri-operative antibiotic prophylaxis and might need adaptation to target the modified microbiome.
