Secondary endoscopic submucosal dissection for residual or recurrent tumors after gastric endoscopic submucosal dissection

Safety and efficacy of secondary endoscopic submucosal dissection for residual gastric carcinoma after primary endoscopic submucosal dissection.

BACKGROUND/AIMS In endoscopic submucosal dissection (ESD), misdiagnosis of the tumor margin may lead to residual carcinoma, which we treat by secondary ESD (sESD) for local control. METHODS 1,458 lesions of early gastric carcinoma were treated by ESD between July 2006 and November 2011. 33 lesions were resected with positive lateral margins. Among them, 13 patients were treated by surgery, 12...

Endoscopic submucosal dissection for colorectal tumors.

BACKGROUND Endoscopic submucosal dissection (ESD) is a state-of-the-art method that enables resection of larger tumors than those resectable by conventional endoscopic mucosal resection (EMR). However, the individual role of each method in the treatment of colorectal tumors remains undetermined. OBJECTIVE AND METHODS To consider the respective indications of ESD and EMR for colorectal tumors,...

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...
