OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included.(More)
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is a technique for "en bloc" resection of superficial tumors of the gastrointestinal tract. In France, experience with this technique is still limited. We wanted to assess the development of ESD in France, with special attention to short term outcomes. PATIENTS AND METHODS Members of the(More)
BACKGROUND AND STUDY AIMS A new core biopsy needle for endoscopic ultrasound (EUS)-guided sampling has recently been developed. The aim of this prospective multicenter study was to compare this needle with a standard needle in patients with solid pancreatic masses. PATIENTS AND METHODS Consecutive patients with solid pancreatic masses referred to 17(More)
BACKGROUND AND STUDY AIMS Histology is the gold standard for the diagnosis of pancreatic adenocarcinoma. However, the negative predictive value of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis remains low. The aims of this prospective multicenter study were: (1) to compare the performance of contrast-harmonic EUS (CH-EUS)(More)
BACKGROUND Pancreatic endoscopic stenting aims to relieve abdominal pain due to chronic pancreatitis. Optimal treatment modalities and post-treatment effects have still to be determined. The object of this study was to investigate the results of a standardized protocol of endoscopic stenting. METHODS Twenty-three patients with abdominal pain due to(More)
INTRODUCTION Data on endoscopic resection of sporadic duodenal adenoma (SDA) are sparse; we present our results concerning safety and efficacy in a retrospective analysis of saline-assisted endoscopic resection of SDA. PATIENTS AND METHODS The cases of all patients who underwent endoscopic resection for SDA between May 1998 and May 2006 were analyzed.(More)
or antiplatelet agents (APA) is a common problem before performing digestive endoscopy. Although risks concerning bleeding are the remit of both the gastroenterologist and anaesthetist, the potential risk of interruption of antithrombotic treatment for the patient should not be underestimated. Faced with the wide variety of situations, it is difficult to(More)
BACKGROUND Few data are available on the accuracy of preoperative imaging or on long-term outcome after surgery for intraductal papillary and mucinous tumors of the pancreas. The aims of this study were to assess the following: (1) the accuracy of preoperative computed tomography, endoscopic retrograde pancreatography, and endoscopic ultrasonography for(More)
With the increasing use of antiplatelet agents (APA), their management during the periendoscopic period has become a more common and more difficult problem. The increase in use is due to the availability of new drugs and the widespread use of drug-eluting coronary stents. Acute coronary syndromes can occur when APA therapy is withheld for noncardiovascular(More)
