BACKGROUND AND STUDY AIM Residual or locally recurrent lesions may occur after endoscopic therapy for epithelial colorectal tumors. Additional endoscopic mucosal resection is difficult for large lesions. Endoscopic submucosal dissection may be useful for such lesions, but may be more technically difficult for residual/locally recurrent lesions than for(More)
Gastric submucosal tumor (SMT) is frequently found during screening endoscopy, but definitive diagnosis based on histological confirmation is relatively difficult. Even without accurate diagnosis before treatment, open or laparoscopic surgery is currently carried out to remove SMT. The purpose of this study was to demonstrate the feasibility of endoscopic(More)
A cell-surface 29-kDa protein (Lam29, cysteine-binding protein of the ABC transporter) from Lactobacillus mucosae ME-340 showed an adhesin-like property for human ABO blood group antigens expressed on the gastrointestinal mucosa. In addition, here we report that Lam29 also bound to an 18-kDa protein on human colonic mucus. By ligand blot assay and(More)
BACKGROUND Esophagogastric junction (EGJ) cancers are not only located in regions anatomically difficult for endoscopic submucosal dissection (ESD), but they also have higher clinicopathological malignant potential than non-junctional gastric cancers (NJC). Despite this, no ESD-based comparative studies of junctional cancer (JC) and NJC have been conducted(More)
AIMS The aims of the present study were to evaluate the feasibility of endoscopic submucosal dissection (ESD) as curative treatment for node-negative submucosal invasive early gastric cancer (EGC) and to consider further expansion of the curability criteria for submucosal invasive EGC. METHODS A total of 977 EGC in 855 patients treated by ESD were(More)
BACKGROUND AND STUDY AIM Esophageal stricture following endoscopic submucosal dissection (ESD) can be a serious complication in patients with large mucosal defects. This preliminary study examined the efficacy of using a polyglycolic acid (PGA) sheet with fibrin glue for the prevention of esophageal stricture after ESD. PATIENTS AND METHODS A total of 15(More)
BACKGROUND Endoscopic submucosal dissection (ESD) was developed to resect early gastric cancer (EGC), which could not be resected by conventional endoscopic mucosal resection, and the indications for ESD are expanding to include more types of EGCs. Favorable long-term outcomes of ESD for EGCs that meet the expanded curability criteria have been reported.(More)
Endoscopic submucosal dissection (ESD) is a widely accepted technique for the management of gastric tumors. However, residual or recurrent tumors can occur after ESD; currently, there is no adequate management strategy for these tumors. Thus, the aim of the present study was to establish a strategy of secondary ESD (sESD) for cases with positive lateral(More)
BACKGROUND AND AIMS To clarify optimal therapeutic strategies for early gastric cancers without vestigial remnant or recurrence, we evaluated the benefits of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) according to tumor size and location. METHODS From January 2000 to December 2007, a total of 328 gastric lesions were(More)
AIM Endoscopic submucosal dissection was developed to address the shortcomings of conventional endoscopic mucosal resection. The present study evaluated the benefits of endoscopic submucosal dissection compared with conventional endoscopic mucosal resection for the treatment of neoplasms arising from the remnant stomach after gastrectomy or esophagectomy.(More)
