Objectives The aim of this study was to compare endoscopic ultrasound‐guided choledochoduodenostomy (EUS‐CDS) vs. EUS‐gallbladder drainage (EUS‐GBD) in cases failed retrograde cholangiopancreatography (ERCP) for jaundice resulting from malignant distal biliary obstruction (MDBO). Methods This multicenter retrospective included patients with obstructive secondary MDBO who underwent EUS‐GBD or EUS‐CDS lumen‐apposing metal stents after ERCP. primary end‐point clinical success rate.

Abstract Background and study aims Capsule endoscopy (CE) is the preferred method for small bowel (SB) exploration. With a mean number of 50,000 SB frames per video, SBCE reading time-consuming tedious (30 to 60 minutes video). We describe large, multicenter database named CAD-CAP (Computer-Assisted Diagnosis CAPsule Endoscopy, CAD-CAP). This serve development CAD tools CE reading. Materials methods Twelve French centers were involved. All available third-generation SB-CE videos (Pillcam,...

Cementless primary total hip arthroplasty (THA) is associated with risks of bleeding and thromboembolism. Anticoagulants are effective as venous thromboprophylaxis, but an increased risk bleeding. Tranexamic acid (TXA) efficient antifibrinolytic agent, the mode timing its administration remain controversial. This study aimed to determine whether two intravenous (IV) TXA regimens (a three-hour two-dose (short-TXA) 11-hour four-dose (long-TXA)) were more than placebo in reducing perioperative...

Summary Background The notion of Crohn's disease (CD) as a chronic, progressive and disabling condition has led to the development new indexes: Lémann Index measuring cumulative bowel damage Inflammatory Bowel Disease (IBD) Disability Index, assessing functional disability. Aims To measure IBD in large prospective cohort CD patients assess correlation between these two indexes. Methods We performed study tertiary referral centre including all consecutive outpatients. assessed questionnaire...

Patients methods This retrospective multicenter included EUS-CDS from 2018 2024. Cases were defined as failure classified follow: type1 (digestive-flange mispositioned), type2 (biliary-flange type3 (stent deployment failure), type4 (catheter-LAMS...

Monitoring muscle atrophy in patients undergoing anterolateral cruciate ligament reconstruction is pivotal for optimizing postoperative recovery. Conventionally, the uninjured contralateral limb serves as control. However, its relevance with prolonged physical activity hiatus due to knee instability remains uncertain. Our objectives were compare limbs within a control group by assessing combined force measurements, cross-sectional areas (CSAs), and neuromuscular activation. In addition, we...

Background: Prospective data about the acceptance and outcomes of switching from adalimumab (ADA) reference product (RP) to multiple ADA biosimilars in inflammatory bowel disease (IBD) patients are lacking. Objectives: To evaluate rate RP biosimilars, identify factors associated with non-acceptance, assess persistence at 6 12 months, determine reasons for discontinuation, analyze changes activity, explore patient perceptions months. Design: A prospective study was conducted a French tertiary...

Abstract Background and aims New techniques for endoscopic resection, including submucosal dissection (ESD), have been developed to allow en-bloc resection with very low recurrence rates organ sparing in patients without inflammatory bowel disease (IBD). Data on ESD the management of colorectal dysplasia IBD are scarce. We aimed evaluate efficacy safety treatment IBD. Methods conducted a retrospective multicenter cohort study that evaluated consecutive procedures visible from 20 French...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown etiology. The treatment UC challenging, especially when it associated with primary sclerosing cholangitis (PSC), the bile ducts that affects around 5% patients UC, and leads to an increased risk cholangiocarcinoma colorectal cancer. Microbiota considered play important role in pathogenesis although efficacy antibiotics this context only limited transient. Several studies have investigated use for PSC adult pediatric...

Infliximab (IFX) is effective in inducing and maintaining remission patients with luminal anoperineal Crohn's disease (CD). However, treatment failure within 12 months after initiating IFX observed a significant proportion of patients. The aim the present study was to determine whether body mass index (BMI) affects response during first year CD. All CD who began between January 2010 May 2014 were prospectively included. BMI calculated before begun, divided into 3 groups: normal (BMI < 25...

Abstract Background Standard high-volume polyethylene glycol [PEG] bowel preparations [PEG-4L] are recommended for patients with inflammatory disease [IBD] undergoing colonoscopy. However, low-volume [≤2 L of active volume] often used in clinical practice. The aim this study was to evaluate the efficacy, tolerability, and safety various IBD, including preparations. Methods We conducted a French prospective multicentre observational over period 1 month. Patients aged 18–75 years IBD an...
