Aims Despite higher en-bloc and curative resection rates, better carcinologic outcomes and lower recurrence rates, colorectal endoscopic submucosal dissection (ESD) development is limited in the West regarding the higher rate of adverse events, especially perforations, than piece-meal endoscopic mucosal resection. This study aims to analyze prevalence, risk factors and clinical outcomes of perforations following colorectal ESD.

Aims The environmental impact of endoscopy, including upper Gi endoscopy (UGE), has gained attention due to its contribution to the global carbon footprint. This study aimed to perform a life cycle assessment of the process of making an endoscope available for upper GI endoscopy, comparing disposable and reusable endoscopes.

Aims Colonoscopy is an invasive procedure that may cause patients pain and discomfort. Moderate to deep sedation is mostly used to ensure quality of the procedure and patients comfort. However, sedation is associated with some risks and side effects. Virtual reality (VR) offers immersive and three-dimensional experiences that distract patients' attention. This prospective comparative open-label study aims to determine if colonoscopies with complete sedation or with VR are equivalent.

Aims EUS biliary drainage called hepaticojejunostomy (EUS-HJ) has not been the subject of even retrospective series. We wanted to report the French experience EUS-HJ by requesting the GRAPHE (group of French digestive endosocopists) for a retrospective multicenter study. The main objective was the technical feasibility of the technique. Main secondary objectives concerned the clinical efficacy, the rate of complications and median survival.

Aims The best biliary drainage procedure in patients with hilar malignant strictures remains controversial. This study compared efficiency and safety of endoscopic and percutaneous transhepatic approaches.

Aims Endoscopic necrosectomy is indicated as a first-line procedure in case of symptomatic solid pancreatic collection following a step-up strategy. The use of luminal apposing metal stent (LAMS) to facilitate the procedure is prospectively poorly established. The aim of this study was to validate the effectiveness of LAMS for endoscopic pancreatic necrosectomy

Aims This retrospective monocentric study aimed to assess predictive value of risk factors for intraductal papillary mucinous neoplasm (IPMN) malignancy according to available international guidelines (American/European guidelines and international consensus) and to assess yield of imaging at Nancy University Hospital.

Aims Colorectal endoscopic submucosal dissection (ESD) is an innovative technique from Japan to resect superficial tumors without any size limit and avoid a complete monobloc resection. Colorectal ESD main complications are perforation, delayed bleeding and post electrocoagulation syndrome (PECS), appearing approximately in 10% of cases. This study aim was to define the incidence of colorectal ESD related complications and identify predictive factors of complications in a French tertiary center.

Aims Cirrhotic patients are considered to be at high risk for esophageal cancer. Nowadays, endoscopic resection is the standard treatment for superficial tumors. Data are lacking about the management of portal hypertension in patients diagnosed with endoscopically resectable tumors. This study aims to assess safety, effectiveness and methods to prevent potential complications, especially bleeding in portal hypertension context.

Treatment of benign biliary obstruction is a challenging situation in patients with altered anatomy. ERCP with single or double balloon enteroscopy can be difficult, with an overall cannulation success of about 60%. We describe the case of a 86-years old women with history of 4/5 gastrectomy and Roux-en-Y anastomosis and main bile duct symptomatic lithiasis, with failure of two enteroscopies. After performing hepaticogastrostomy, we performed an anterograde electrohydraulic lithotripsy using an ultraslim videogastroscope as a cholangioscope. A guidewire was placed during cholangioscopy to place a transpapillary biliary metallic stent to enable complete biliary stones clearance.

Aims Development of ESD in Europe remains limited compared to Japan. ESGE lately published a position statement for the training in ESD. We aimed to compare the learning curves of three french centers, with different curriculum.

We report the case of a patient with main bile duct stones, confirmed after EUS examination. The endoscopic view of the duodenal tract showed an intradiverticular papilla. In order to facilitate the exposure of the papilla, we proceed to a counter traction by clip and rubber band. A first Boston Resolution 360 clip, on which was hung a dental rubber band (Ormco Ostrich 19.1 mm) was set up in para-papillary position by the operating channel of the duodenoscope (Olympus). A second clip was introduced into the operator channel to tract the elastic on the outer edge of the duodenum. The papillary exposure was improved and cannulation of the main bile duct was achieved in 3 minutes and 10 seconds with a Boston Jagwire guide wire and a Boston sphincterotome 4.4. After performing a sphincterotomy, the stones were extracted with an balloon and hemostatic compression was performed due to post-sphincterotomy bleeding. The haemostasis was completed by the placement of a covered SEMS Cook Evolution 40 × 10 mm, then by the injection of saline and adrenaline 1/1000.
