Endoscopic submucosal dissection (ESD) and transanal endoscopic microsurgery (TEM) are minimally invasive procedures that can be used to treat early rectal cancer. The aim of this study was to compare clinical efficacy between ESD and TEM for the treatment of early rectal cancer. Between July 2008 and August 2011, 24 patients with early rectal cancers were(More)
The use of self-expandable metallic stents has increased recently to palliate inoperable esophageal neoplasia and also in the management of benign strictures. Migration is one of the most common complications after stent placement and the endoscopist should be able to recognize and manage this situation. Several techniques for managing migrated stents have(More)
CONTEXT Endosonography-guided biliary drainage has been used over the last few years as a salvage procedure when endoscopic retrograde cholangiopancreatography fails. Malignant gastric outlet obstruction may also be present in these patients. We report the results of both procedures during the same session in patients with duodenal and biliary obstruction(More)
BACKGROUND The source and outcomes of upper gastrointestinal bleeding (UGIB) in oncologic patients are poorly investigated. OBJECTIVE The study aimed to investigate these issues in a tertiary academic referral center specialized in cancer treatment. METHODS This was a retrospective study including all patients with cancer referred to endoscopy due to(More)
Use of fully and partially covered selfexpanding metallic esophageal stents (SEMS) is associated with high rates of migration [1]. Stent modification with a silk thread to permit external fixation, proposed by Shim et al., has been shown to reduce migration [2] but this stent may not be routinely available. Therefore we present another modified stent(More)
BACKGROUND AND AIMS Surveillance programs of patients with head and neck cancer (HNC) detect synchronous or metachronous esophageal squamous cell carcinoma (ESCC) in up to 15% of patients. Noninvasive, probe-based confocal laser endomicroscopy (pCLE) technique may improve the diagnosis allowing acquisition of high-resolution in vivo images at the cellular(More)
The endoscopic resection of rectal neuroendocrine tumors (NETs) results in good long-term outcomes [1]. Many techniques for the endoscopic resection of rectal NETs have been described, including polypectomy, endoscopic mucosal resection (EMR), and recently EMR with band ligation [2], endoscopic submucosal dissection [3], and even transanal endoscopic(More)
A 79-year-old man with metastatic adenocarcinoma of the cardia was submitted to palliative chemotherapy and esophageal stenting for relief of dysphagia. After the fourth cycle of chemotherapy he was admitted to the emergency department complaining of dysphagia. At endoscopy a significant regression of the lesion size and migration of the stent into the(More)
