BACKGROUND Benign esophageal strictures refractory to standard dilation therapy present a challenging problem. Temporary plastic and metal stents have been proposed with inconclusive results. OBJECTIVE To evaluate the efficacy and safety of a new biodegradable stent for the treatment of refractory benign esophageal strictures (RBESs). DESIGN AND SETTING(More)
BACKGROUND Placement of self-expanding metal stents (SEMS) or plastic stents (SEPS) has emerged as a minimally invasive treatment option for benign oesophageal ruptures and leaks; however, it is not clear which stent type should be preferred. AIM To assess clinical effectiveness and safety of treating benign oesophageal ruptures and anastomotic leaks with(More)
BACKGROUND Benign esophageal ruptures and anastomotic leaks are life-threatening conditions that are often treated surgically. Recently, placement of partially and fully covered metal or plastic stents has emerged as a minimally invasive treatment option. We aimed to determine the clinical effectiveness of covered stent placement for the treatment of(More)
BACKGROUND Benign biliary strictures may be a consequence of surgical procedures, chronic pancreatitis or iatrogenic injuries to the ampulla. Stents are increasingly being used for this indication, however it is not completely clear which stent type should be preferred. METHODS A systematic review on stent placement for benign extrahepatic biliary(More)
BACKGROUND Metal stents are frequently used for palliation of malignant dysphagia. Recently, a new stent design, the partially covered Wallflex stent (Boston Scientific, Natick, Mass), has been introduced. OBJECTIVE To determine clinical effectiveness and safety of the esophageal Wallflex stent for the palliation of dysphagia. DESIGN A prospective(More)
BACKGROUND AND STUDY AIM Although biodegradable stents do not require removal, a single biodegradable stent may only temporarily relieve dysphagia in patients with refractory benign esophageal stricture (RBES). The aim of this study was to evaluate the safety and long term efficacy of single and sequential biodegradable stent placement in patients with(More)
BACKGROUND To examine the association of education with body mass index (BMI) and waist circumference (WC) in the European Prospective Investigation into Cancer and Nutrition (EPIC). METHOD This study included 141,230 male and 336,637 female EPIC-participants, who were recruited between 1992 and 2000. Education, which was assessed by questionnaire, was(More)
OPINION STATEMENT Benign esophageal strictures arise from a diversity of causes, for example esophagogastric reflux, esophageal resection, radiation therapy, ablative therapy, or the ingestion of a corrosive substance. Most strictures can be treated successfully with endoscopic dilation using bougies or balloons, with only a few complications. Nonetheless,(More)
BACKGROUND Self-expandable metal stents (SEMSs) are increasingly used for the treatment of benign biliary strictures (BBSs). A new fully covered SEMS (FCSEMS) with flared ends and high conformability was designed to prevent migration of the stent. OBJECTIVE To evaluate the efficacy of a novel FCSEMS with antimigration features. DESIGN Prospective cohort(More)
Biodegradable stents overcome some of the problems encountered with self-expanding metal stents. They main advantage over self-expanding metal stents is that endoscopic removal is not needed. Single biodegradable stents are often only temporarily effective in patients with a refractory benign esophageal stricture, as in the majority dysphagia recurs. If(More)
