Grasper type scissors for endoscopic submucosal dissection of gastric epithelial neoplasia

Endoscopic gastric submucosal dissection in low-grade intraepithelial neoplasia.

Endoscopic mucosal resection (EMR) was developed for the purpose of preserving complete gastrointestinal function after the resection of a lesion limited to the mucosa of the digestive tract, as well as for obtaining larger specimens that would enable a precise histopathologic diagnosis. In Japan, different techniques were developed for EMR that were divided into three modalities: EMR with a do...

Endoscopic submucosal dissection for anal intraepithelial neoplasia

A 68-year-old woman was found to have a 20-mm superficial lesion at the dentate line (Fig. 1). Narrow band imaging (NBI) revealed a well-demarcated area with irregular intrapapillary capillary loops, similar to the findings seen in esophageal superficial squamous cell carcinoma [1]. Endoscopic biopsy revealed a high-grade squamous intraepithelial lesion (HSIL). After delineating the lesion unde...

Endoscopic Submucosal Dissection for Early Gastric Cancer

The field of endoscopy has progressed markedly and become widespread in recent years, and the role of minimally invasive endoscopic treatment has become increasingly more important with the increase in the number of patients in whom gastric cancer is detected at an early stage. In addition, the characteristics of early gastric cancer, which can be curably treated by mucosal resection alone just...

[Endoscopic submucosal dissection for early gastric cancer].

Endoscopic mucosal resection (EMR) has been accepted as a treatment of early gastric cancer (EGC). The number of EMR procedures for EGC has been increasing because a patient's quality of life after EMR is superior to that after surgical gastrectomy. In Japan, most EMR have been performed using the strip biopsy method; however, in some cases we experienced local recurrences when multiple fragmen...
