Usefulness of endoscopic radial incision and cutting method for refractory esophagogastric anastomotic stricture (with video).
BACKGROUND There is no effective treatment for gastroesophageal anastomotic strictures that are refractory to repeated endoscopic balloon dilation (EBD). However, EBD is still selected worldwide to… Expand
A large-scale multicenter study of long-term outcomes after endoscopic resection for submucosal invasive colorectal cancer.
BACKGROUND AND STUDY AIMS Patients with submucosal invasive colorectal cancer (SM-CRC) treated with endoscopic resection who are at low risk of lymph node metastasis and local recurrence may be… Expand
Clinical impact of surveillance for head and neck cancer in patients with esophageal squamous cell carcinoma
AIM To evaluate the clinical impact of surveillance for head and neck (HN) region with narrow band imaging (NBI) in patients with esophageal squamous cell carcinoma (ESCC). METHODS Since 2006, we… Expand
Endoscopic balloon dilatation for benign fibrotic strictures after curative nonsurgical treatment for esophageal cancer
BackgroundEndoscopic balloon dilatation (EBD) is performed to treat strictures after esophagectomy. However, little is known about using EBD for benign strictures that occur after nonsurgical… Expand
Phase I study of photodynamic therapy using talaporfin sodium and diode laser for local failure after chemoradiotherapy for esophageal cancer
BackgroundPhotodynamic therapy (PDT) is a less invasive and effective salvage treatment for local failure after chemoradiotherapy (CRT) for esophageal cancer, however it causes a high rate of skin… Expand
Salvage photodynamic therapy for local failure after chemoradiotherapy for esophageal squamous cell carcinoma.
BACKGROUND AND AIMS Photodynamic therapy (PDT) is a less-invasive salvage treatment option for local failure at the primary site after chemoradiotherapy (CRT) for esophageal squamous cell carcinoma.… Expand
Radial incision and cutting method for refractory stricture after nonsurgical treatment of esophageal cancer.
Strictures remaining after nonsurgical treatment for esophageal cancer are generally more refractory to endoscopic balloon dilation (EBD) when compared with anastomotic strictures. The aim of the… Expand
Prospective trial of biodegradable stents for refractory benign esophageal strictures after curative treatment of esophageal cancer.
BACKGROUND AND AIMS Biodegradable stents are reportedly effective for refractory benign esophageal strictures; however, little is known about their use in patients with refractory stricture after… Expand
Evaluation of complications related to therapeutic colonoscopy using the bipolar snare
BackgroundThe complications with therapeutic colonoscopy reported to date have been associated with the monopolar snare, and the frequency of complications related to use of the bipolar snare is… Expand
Clinicopathological features and endoscopic findings of HER2-positive gastric cancer
BackgroundHuman epidermal growth factor receptor 2 (HER2) expression in gastric cancer is highly heterogeneous. Therefore, it is important to take endoscopic samples from appropriate tumor… Expand
