OBJECTIVE To estimate the safety and efficacy of submucosal tunneling endoscopic resection (STER) for upper gastrointestinal submucosal tumors (SMTs) originating from the muscularis propria layer. METHODS During October 2011 and May 2014, a total of 80 patients with SMTs underwent STER at our hospital. A submucosal tunnel was created from 3-5 cm above the(More)
Submucosal tunneling endoscopic resection (STER) is a new treatment technique for upper gastrointestinal submucosal tumors (SMT) originating from the muscularis propria (MP) layer. In contrast to conventional endoscopic resection, the new therapy can maintain the mucosal integrity of the digestive tract, which effectively prevents mediastinitis and(More)
Submucosal tunneling endoscopic resection (STER) has been proved to be safe and effective for removal of esophageal leiomyoma originating from the muscularis propria (MP) layer. However, there are still technical challenges for tumors ≥35 mm due to the limited space of the submucosal tunnel. The aim of the study was to estimate the safety and efficacy of(More)
Dear Editor: Anastomotic benign stricture develops in 3–30 % of patients after surgery for rectal carcinoma. Although most of the strictures can be successfully managed with dilation, refractory stricture that does not respond to repeated dilations is difficult to be managed. Affected patients often suffer from constipation, abdominal pain, bloating, and(More)
Extracellular nucleotides uridine-5'-triphosphate (UTP) and adenosine-5'-triphosphate (ATP) induce contraction of gastric smooth muscle (SM). The dinucleotide uridine adenosine tetraphosphate (Up4 A), an endothelium-derived contraction factor, induces vascular SM contraction. Its effect on gastric SM contractions, however, is unknown. We addressed the(More)
OBJECTIVE Mediastinitis secondary to hypopharyngeal and esophageal foreign bodies is a rare but lethal complication. So far, no literature on a large scale has been reported. This investigation reviewed cases of mediastinitis associated with foreign body ingestion during the past 40 years. STUDY DESIGN Case series with chart review. SETTING Second(More)
PURPOSE This study analyzes the efficacy and safety of a retrievable, fully covered self-expanding metal stent (cSEMS) in the treatment of refractory benign esophageal restenosis in children. METHODS This is a retrospective analysis of the application of a newly designed cSEMS in treating refractory benign postoperative restenosis in five children with(More)
