    Abstract Celiac disease (CeD) is a chronic immune-mediated condition triggered by gluten consumption in genetically predisposed individuals. Approximately 1% of the general population is affected by the disorder. Disease presentation is heterogeneous and, despite growing awareness among physicians and the public, it continues to be underestimated. The most effective strategy for identifying undiagnosed CeD is proactive case finding through serologic testing in high-risk groups. We reviewed the most recent evidence on the association between CeD and more than 20 conditions. In light of this review, CeD screening is recommended in individuals with (1) autoimmune disease and accompanying symptoms suggestive of CeD; (2) diseases that may mimic CeD (eg, irritable bowel syndrome [IBS], inflammatory bowel disease [IBD], and microscopic colitis); and (3) among patients with conditions with a high CeD prevalence: first-degree relatives, idiopathic pancreatitis, unexplained liver enzyme abnormalities, autoimmune hepatitis, primary biliary cholangitis, hyposplenism or functional asplenia with severe bacterial infection, type 1 diabetes mellitus, Hashimoto's thyroiditis and Graves' disease, Sjögren's syndrome, dermatitis herpetiformis, recurrent aphthous syndrome and enamel defects, unexplained ataxia, peripheral neuropathy, delayed menarche or premature menopause, Down syndrome, Turner syndrome, Williams syndrome, chronic fatigue syndrome, IgA nephropathy, and IgA deficiency. CeD serology should be the initial step in the screening process. However, for patients with any of the aforementioned disorders who are undergoing upper endoscopy, biopsies should be performed to rule out CeD.

    Abstract Refractory celiac disease (RCD) refers to persistence of malnutrition and intestinal villous atrophy for more than 1 to 2 years despite strict gluten-free diet in patients with celiac disease. Diagnosis remains difficult and impacts treatment and follow-up. RCD has been subdivided into 2 subgroups according to the normal (RCDI) or abnormal phenotype of intraepithelial lymphocytes (IELs) (RCDII). RCDII is considered as a low-grade intraepithelial lymphoma and has a poor prognosis due to gastrointestinal and extraintestinal dissemination of the abnormal IELs, and high risk of overt lymphoma.

    Abstract Lynch syndrome (LS) is an inherited predisposition to colorectal cancer (CRC), responsible for 3-5% of all CRC. This syndrome is characterized by the early occurrence of colorectal neoplastic lesions, with variable incidences depending on the type of pathogenic variants in MMR genes (MLH1, MSH2, MSH6, PMS2 and EPCAM) and demographics factors such as gender, body mass index, tobacco use and physical activity. Similar to sporadic cancers, colorectal screening by colonoscopy is efficient because it is associated with a reduction >50% of both CRC incidence and CRC related mortality. To that end, most guidelines recommend high definition screening colonoscopies in dedicated centers, starting at the age of 20-25 years old, with a surveillance interval of 1-2 years. In this review, we discuss the importance of high definition colonoscopies, including the compliance to specific key performance indicators, as well as the expected benefits of specific imaging modalities including virtual chromoendoscopy and dye-spray chromoendoscopy.

    Title translation Role of the PRED-IdF, a regional network dedicated to patients with hereditary predisposition to digestive cancers.
    Abstract Patients with hereditary predisposition to digestive cancer are at high risk of neoplasia and management in expert centers is recommended. The PRED-IdF network was thus created in 2009, with the support of the French National Cancer Institute (INCa), covering Paris and its suburbs, including five teaching hospitals and two oncology-dedicated institutes. The aim of this network is to offer optimized cancer screening programs based on expert recommendations to patients with hereditary predisposition. Any patient with suspicion of hereditary colorectal syndrome can be referred to the PRED-IdF network. The missions of this network include the establishment of a personalized screening program (PSP), coordination of PSP, expertise/recourse for difficult cases and research. Since 2009, 3384 patients have been included. We genetically identified 1925 patients with Lynch syndrome and 539 with familial adenomatous polyposis (FAP) (including both APC and MUTYH mutations), representing 72.8% of the PRED-IdF cohort. The PRED-IdF is also an important promotor of research in the field. We recently demonstrated the beneficial impact of the network in terms of colorectal cancer occurrence in patients with Lynch syndrome. Moreover, the PRED-IdF is involved in many studies ranging from basic science collaborations to randomized controlled trials. The long-term objective is to offer to all patients a personalized medical approach.

    Abstract Capsule endoscopy (CE), which allows the non-invasive visualisation of mucosa throughout the entire small bowel, has revolutionised the exploration of small-bowel diseases, and particularly the evaluation of obscure gastrointestinal bleeding (OGIB) after a negative initial evaluation, including gastroscopy and colonoscopy. CE has a high negative predictive value and a higher diagnostic yield than all other modalities, such as radiology (small-bowel X-rays or computed tomography scan) or push enteroscopy. CE may be the preferred initial diagnostic choice in OGIB because of its non-invasive quality and better tolerance. Double-balloon enteroscopy, also known as push-and-pull enteroscopy, has recently been developed. It has made it possible not only to explore the small bowel but also to carry out therapeutic interventions deep in the small bowel without the need for surgical laparotomy. This exploration should be considered as a second-line exploration for OGIB in patients with a positive finding on CE requiring endoscopic follow-up for histology or intervention, and in patients in whom suspicion of a small-bowel lesion is high despite a negative CE.

    Abstract Endoscopic submucosal dissection (ESD) is a validated treatment for early rectal tumors, but whether this therapy is efficient or not for rectal tumors extending to the dentate line (RTDL) remains unclear. We performed a systematic review and meta-analysis to assess the effectiveness and safety of ESD in RTDL compared to non-RTDL. A search in PubMed, Scopus and the Cochrane library up to April 2020 was conducted to identify studies that compared ESD in both localizations (RTDL and non-RTDL), reporting at least one main outcome (en bloc, complete resection, recurrence). Secondary outcomes were adverse event occurrence. Five observational studies including 739 patients with a total of 201 RTDL and 538 non-RTDL were considered. The proportion of female sex (66% vs. 36.9%, P < 0.001) and tumor size [mean difference = 7.75, 95% confidence interval (CI): 3.01-12.49, P = 0.001] were higher in the RTDL group. There were no differences in en bloc resection rates between RTDL and non-RTDL groups [odds ratio (OR): 0.95, 95% CI: 0.50-1.79, P = 0.087]. The complete resection rate was significantly higher in the non-RTDL group (OR: 1.72, 95% CI: 1.18-2.53, P = 0.005, I2 = 0%). However, recurrence rates were comparable (RD: -0.04, 95% CI: -0.07 to 0.00, P = 0.06, I2 = 0%). Concerning adverse events, there were no differences in terms of perforation (OR: 0.9, 95% CI: 0.26-3.08, P = 0.86, I2 = 0%) or delayed bleeding (OR: 0.64, 95% CI: 0.17-2.42, P = 0.51, I2 = 35%). Anal pain rate was 28% (95% CI: 21.4-35.8%). ESD is an effective and safe therapeutic approach for RTDL with comparable recurrence rate to non-RTDL. The lower complete resection rate in RTDL needs to be clarified in studies.
