Difficulties in the preoperative diagnosis of gastrointestinal submucosal tumors by endoscopic ultrasonography and errors of tissue sampling may make invasive surgery [1] or endoscopic resection [2] inappropriate for their removal. Better methods of diagnosing submucosal tumors are therefore needed. We have found that bloc biopsy and use of the submucosal endoscopy with a mucosal flap (SEMF) me...
Large (>2.5 cm) rectal laterally spreading tumors (LSTs) are often managed endoscopically with piecemeal endoscopic mucosal resection technique (pEMR). However, the mean recurrence rate after pEMR is 20% [1]. Furthermore, rectal LST-mixed granular type lesions (0-Is+IIa) demonstrate deep submucosal cancerous infiltration in 10.1% of cases [2]. Endoscopic submucosal dissection (ESD) is an endosc...
PURPOSE Transanal endoscopic microsurgery provides a minimally invasive alternative to radical surgery for excision of benign and malignant rectal tumors. The purpose of this study was to review our experience with transanal endoscopic microsurgery to clarify its role in the treatment of different types of rectal pathology. METHODS A prospective database documented all patients undergoing tra...
Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Two cases of intramucosal adenocarcinoma originating from gastric hyperplastic polyps that were successfully removed by endoscopic mucosal resection or endoscopic submucosal dissection are reported. On pathological examination, adenocarcinoma limited to the hyperplastic...
To discuss the rationale for the widespread application of endoscopic mucosal resection (EMR) rather than endoscopic submucosal dissection (ESD) in Western centers. In Western centers, EMR is the treatment of choice for most non-pedunculated colorectal adenomas >2 cm in size. EMR is sufficiently effective and safe to be performed without post-procedure hospitalization. Advances in EMR have led ...
PURPOSE Endoscopic submucosal dissection has recently been practiced on a differentiated type of early gastric cancer. However, there is no clear evidence for endoscopic treatments of signet ring cell carcinoma. The aim of this study is to identify the predictive clinicopathological factors for lymph node metastasis in signet ring cell carcinoma for assisting endoscopic submucosal dissection tr...
Diagnosis. A VS800 (OLYMPUS, Tokyo, Japan) in a WSI system and an AS-400 (KURABO, Tokyo, Japan) for the ASP systemwere used. Up to 100 slides consisting of biopsy, endoscopic mucosal resection (EMR), or endoscopic submucosal dissection (ESD) specimenswere scanned and stored digitally in one set and the digital images were viewed on a monitor in a separate room using a VS800 viewer. Ocular obser...
