BACKGROUND Helicobacter pylori infection is associated with gastric cancer, but the effect of eradication treatment on gastric cancer risk is not well defined. PURPOSE To determine whether H. pylori eradication treatment can reduce the risk for gastric cancer. DATA SOURCES PubMed, EMBASE, Cochrane Library, Google Scholar, and online clinical trial(More)
BACKGROUND AND STUDY AIMS Precut papillotomy is considered a risk factor for endoscopic retrograde cholangiopancreatography (ERCP)-related complications; however whether the complication risk is due to precut itself or to the prior prolonged attempts is still debated; therefore, early precut implementation has been suggested to reduce the complication rate.(More)
OBJECTIVES The most common technique used to achieve primary deep biliary cannulation is the standard contrast-assisted method. To increase the success rate and reduce the risk of complications, a wire-guided cannulation strategy has been proposed. Prospective studies provided conflicting results as to whether the wire-guided cannulation technique increases(More)
BACKGROUND & AIMS Data on the safety of bevacizumab-based therapies for patients carrying a self-expandable metallic stent (SEMS) for occlusive colon cancer are lacking. We report 2 cases of colon perforation observed in our case series of patients with SEMS for occlusive colon cancer. METHODS Patients with occlusive symptoms caused by colon cancer(More)
Surgical decompression is the traditional treatment for acute colorectal cancer obstruction. In recent years, colorectal stenting has been used to relieve the obstruction. This study used meta-analytic techniques to compare colonic stenting versus surgical decompression for colorectal cancer obstruction. A comprehensive search of several databases was(More)
BACKGROUND AND AIM Gastric antral vascular ectasia (GAVE) is a cause of bleeding in patients with liver cirrhosis. Argon plasma coagulation (APC) is the most used endoscopic treatment for GAVE-related bleeding. Treatment failures have been described in patients with haemorrhagic diathesis; post-procedure complications include haemorrhages and septicaemia.(More)
BACKGROUND The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity model, and its Portsmouth and colorectal modifications are used to predict postoperative mortality and morbidity after colorectal surgery. AIMS To compare stent placement as a bridge to surgery vs. emergency surgical resection in patients with acute(More)
Computed Tomography (CT) and Magnetic Resonance (MR) permit the acquirement of important diagnostic elements for the anatomo-topographic staging of substernal goiters, and for their characterization. The authors compared data obtained by CT and MR with intraoperative anatomo-topographic findings and definitive histology in 28 patients with substernal(More)
We present an initial report regarding the clinical usefulness of peroral cholangioscopy, using a new type of cholangioscope, the Polyscope. Peroral cholangioscopy was performed in four patients with strictures after orthotopic liver transplantation (OLT) which were suspected of being ischemic biliary lesions, in three with indeterminate biliary strictures,(More)
BACKGROUND AND AIMS Probiotic supplementation seems to provide beneficial effects in the prevention and treatment of radiation-induced diarrhea. We performed a systematic review and meta-analysis to estimate the efficacy of probiotic supplementation for prevention and treatment of radiation-induced diarrhea. METHODS Two reviewers independently searched(More)
