BACKGROUND Endoscopic sphincterotomy (ES) is an established treatment for patients with choledocholithiasis or common bile duct stones (CBDS), but further management of patients after ES with recurrent CBDS remains controversial. Endoscopic papillary large balloon dilation (EPLBD) has been used safely and effectively for stone removal in patients after ES with recurrent CBDS. The aim of this st...

Objectives. Balloon dilation laryngoplasty has been suggested as an alternative treatment to open surgical treatment of acquired subglottic stenosis in children. We describe long-term outcomes of balloon dilation for acquired subglottic stenosis in children. Methods. The medical charts of children who had balloon dilation for subglottic stenosis secondary to intubation were reviewed. Data inclu...

Benign colorectal strictures have numerous causes, including postoperative stenosis, radiation, diverticular disease, ischemia, and inflammatory bowel disease. Although surgical management was once considered the standard treatment for benign colorectal strictures, advances in endoscopic techniques and various accessories have enabled successful treatment of benign colorectal strictures using e...

A 29-year-old woman was referred to our department for endoscopic dilation of upper esophageal stricture. Dilation was performed with Savary–Gilliard dilators allowing the passage with resistance of a standard flexible video gastroscope (EG-201FP; Fujinon, Willich, Germany). Esophagogastroduodenoscopy showed a double esophageal lumen at 18cm from the incisors. A thick bridge of intact mucosa se...

BACKGROUND Arterial remodeling after balloon angioplasty has been recognized as a major determinant of restenosis. Perturbation of collagen metabolism might be important. After balloon injury, matrix metalloproteinase (MMP) expression is upregulated. We investigated the effect of Batimastat, a nonspecific MMP inhibitor, on late lumen loss, arterial remodeling, and neointima formation after ball...

Biliary endoscopic sphincterotomy (ES) followed by biliary orifice dilation (BOD) with large-diameter balloons (> 12 mm) is a relative new technique for extraction of large biliary stones. However, the safety and the potential complications of this combined technique are not known yet. We present a patient who developed benign retroperitoneum after ES plus BOD with large-diameter balloon for re...

AIM To examine the influence of night duty (ND) on endoscopic therapy for biliary duct stones. METHODS The subjects consisted of 133 patients who received initial endoscopic therapy for biliary duct stones performed by eight endoscopists after they had been on (ND group, n = 34 patients) or not [day duty (DD) group, n = 99 patients]. Patient characteristics (age, gender, history of abdominal ...
