BACKGROUND AND STUDY AIM Benign biliary diseases include benign biliary stricture (BBS), lithiasis, and leaks. BBSs are usually treated with plastic stent placement; use of uncovered or partially covered metallic stents has been associated with failure related to mucosal hyperplasia. Some recently published series suggest the efficacy of fully covered(More)
Through-the-scope clips are commonly used for endoscopic hemostasis of gastrointestinal (GI) bleeding, but their efficacy can be suboptimal in patients with complex bleeding lesions. The over-the-scope clip (OTSC) could overcome the limitations of through-the-scope clips by allowing compression of larger amounts of tissue, allowing a more efficient(More)
OBJECTIVES To evaluate the short- and long-term efficacy of self-expanding metal stents (SEMSs) in patients with colorectal obstruction and incurable cancer and the related factors that affect outcomes. DESIGN Retrospective analysis of SEMS placement for incurable colorectal obstruction in a 3-year period. SETTING Five tertiary care endoscopic centers.(More)
BACKGROUND AND STUDY AIMS Optical coherence tomography (OCT) permits high-resolution imaging of tissue microstructures using a probe that can be inserted into the main pancreatic duct (MPD) through a standard endoscopic retrograde cholangiopancreatography (ERCP) catheter. This prospective study was designed to assess the diagnostic capacity of OCT to(More)
OBJECTIVE The aim of this prospective study was to compare the feasibility, technical success rate and complication between single-step endo-ultrasonography (EUS)-guided and two-step EUS-guided drainage technique for symptomatic pancreatic pseudocyst (PP). METHODS Twenty-one PP patients with clear intra-cystic fluid that needed to be drained were divided(More)
BACKGROUND Fully covered self-expanding metal stents are now being used to treat benign biliary diseases. AIMS To assess the outcomes of these stents as first-step therapy in patients with biliary leaks secondary to hepato-biliary surgery. METHODS Thirty patients (56.7% males; mean age: 60.2 ± 13 years) were retrospectively evaluated. The data collected(More)
BACKGROUND Optical coherence tomography has been proposed to obtain high-resolution imaging of tissue structure of GI tract. Up till now, the optical coherence tomography appearance of the common bile duct, main pancreatic duct and sphincter of Oddi wall structure has not yet been defined. AIMS To compare, in a prospective study, optical coherence(More)
Iatrogenic perforations that occur during the endoscopic procedures are generally surgically managed, even if some authors prefer a non-surgical approach in selected cases. The endoscopic application of metallic clips has been widely used in the gastrointestinal (GI) tract for hemostasis and also for marking lesions. Since 1993 several series of endoscopic(More)
The intraoperative identification of the lesions found at endoscopic examination is often difficult, especially during laparoscopic surgery. At present, the most used technique for the intraoperative detection of pathological lesions is endoscopic tattooing. The large majority of studies carried out concern colorectal lesions; however, endoscopic tattooing(More)
