OBJECTIVE Esophageal tumors arising in the muscularis propria are difficult to be resected endoscopically using standard electro-surgical techniques, even the endoscopic submucosal dissection (ESD) technique appeared recently. Our purpose is to investigate the efficacy of endoscopic ultrasound (EUS)-assisted tunnel-type ESD for resection of these tumors. (More)
An 85-year-old male patient with common bile duct stones and gallbladder stone was admitted to the hospital. Endoscopic ultrasound (EUS)-guided cholecystogastrostomy and the placement of a novel covered mental stent was performed after the endoscopic sphincter ectomy procedure. Two weeks later the stents were removed, and an endoscope was advanced into the(More)
BACKGROUND Laparoscopic cholecystectomy (LC) has become the 'gold standard' for the treatment of symptomatic gallstones. Innovative methods are being introduced, and these procedures include transgastric or transcolonic endoscopic cholecystectomy. However, before clinical implementation, instruments still need modification, and a more convenient treatment(More)
BACKGROUND Oct4 and Sox2 are two major transcription factors related to the stem cell self-renewal and differentiation. The aim of this study was to examine the association between Oct4 and Sox2 expression levels with both the clinicopathological characteristics and prognoses of patients with hypopharyngeal squamous cell carcinoma. METHOD Tumor tissue(More)
Submucosal tumors (SMTs) are usually discovered fortuitously during routine endoscopy, including various non-neoplastic and neoplastic conditions. Endoscopic ultrasound (EUS) is considered to be the best imaging procedure to characterize SMTs and to determine the need for further treatment. In this review, the following issues will be addressed: The role of(More)
This study was designed to determine the pattern and correlation between expression of the HIF-1α transcriptional targets TGM2 and BNIP3 in laryngeal cancer, and investigate the association of BNIP3 and TGM2 with clinical outcome in laryngeal squamous cell carcinoma (SCC) patients receiving postoperative radiotherapy. Immunostaining with antibodies specific(More)
BACKGROUND The combined predictive value of plasma uric acid and primary tumor volume in nasopharyngeal carcinoma (NPC) patients receiving intensity modulated radiation therapy (IMRT) has not yet been determined. METHODS In this retrospective study, plasma uric acid level was measured after treatment in 130 histologically-proven NPC patients treated with(More)
For the management of pancreatic abscess, endoscopic ultrasound (EUS)-guided puncture and drainage has become recognized as a safer and more effective alternative to surgery. Typically, a double-pigtail plastic stent is placed for drainage. When an abscess is complicated by infected necrosis, endoscopic evacuation is essential. However, endoscopic(More)
BACKGROUND Ligation-assisted endoscopic enucleation (EE-L) was developed for the pathological diagnosis and resection of small gastrointestinal tumors originating from the muscularis propria. The technique combines endoscopic band ligation and endoscopic enucleation. The aim of this study was to evaluate the efficacy and safety of EE-L in the diagnosis and(More)
