BACKGROUND Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has proven to be safe and effective in patients with early neoplasia in Barrett's esophagus. However, long-term results in patients with high-grade intraepithelial neoplasia (HGIN) or with early cancer are still lacking. METHODS The aim of the study was to evaluate the efficacy of(More)
BACKGROUND AND STUDY AIMS The increasing use of flexible endoscopy to treat symptomatic Zenker's diverticulum is only partially supported by data on safety and benefits. This retrospective study reports the mid-term results of argon plasma coagulation (APC) for flexible endoscopic therapy of Zenker's diverticulum. PATIENTS AND METHODS Between January 2002(More)
OBJECTIVES Standard colonoscopy offers no reliable discrimination between neoplastic and nonneoplastic colorectal lesions. Computed virtual chromoendoscopy with the Fujinon intelligent color enhancement (FICE) system is a new dyeless imaging technique that enhances mucosal and vascular patterns. This prospective trial compared the feasibility of FICE,(More)
BACKGROUND & AIMS Barrett's esophagus-associated high-grade dysplasia is commonly treated by endoscopy. However, most guidelines offer no recommendations for endoscopic treatment of mucosal adenocarcinoma of the esophagus (mAC). We investigated the efficacy and safety of endoscopic resection in a large series of patients with mAC. METHODS We collected(More)
BACKGROUND & AIMS The aim of this study was to compare magnified still images obtained with high-resolution white light endoscopy, indigo carmine chromoendoscopy, acetic acid chromoendoscopy, and narrow-band imaging to determine the best technique for use in Barrett's esophagus. METHODS We obtained magnified images from 22 areas with the 4 aforementioned(More)
A 70-year-old woman presented with a persistent, nonmalignant esophagorespiratory fistula. Since other treatment options failed or were denied, an experimental nonsurgical therapy was performed. A self-expanding ventricular septal defect (VSD) occlusion device (Amplatzer; AGA Medical Corporation; Golden Valley, MN) was bronchoscopically introduced to close(More)
BACKGROUND Endoscopic therapy (ET) has become a less risky alternative to open surgery in mucosal Barrett's cancer (BC) because of the very low risk of lymph node (LN) metastasis. Recently published surgical series demonstrated that even in case of minimal submucosal invasion of BC, the risk for LN metastasis is very low. In consequence, also these patients(More)
BACKGROUND An exploratory analysis of a prospective study of risk factors for acute pancreatitis after ERCP combined with endoscopic sphincterotomy showed that the frequency of acute pancreatitis was lower in patients who received heparin compared with patients not treated with heparin. The study was continued to further analyze the effect of heparin on the(More)
BACKGROUND Although the efficacy of extracorporeal shockwave lithotripsy for treatment of bile duct calculi is established, there are few studies of the value of extracorporeal shockwave lithotripsy for cystic duct remnant stones and for Mirizzi syndrome. METHODS Patients who required extracorporeal shockwave lithotripsy for cystic duct stones were(More)
BACKGROUND & AIMS Confocal laser endomicroscopy has been shown to allow direct histologic imaging of gastrointestinal tumors in vivo. This study was designed to assess the potential of endomicroscopy for predicting histology in vivo during routine endoscopy in patients with early squamous cell cancer. METHODS Twenty-one consecutive patients with suspected(More)
