Background/Aims: Delayed bleeding after gastric endoscopic submucosal dissection (ESD) commonly occurs within 3 days, but it may also occur after 1 week following ESD, especially in antiplatelet agent users. We evaluated the risk of delayed bleeding in post-ESD ulcers using the Forrest classification. Methods: Registry data on the Forrest classification of post-ESD ulcers (n=371) at 1 week or 2 weeks after ESD were retrospectively evaluated. The Forrest classification was categorized into two groups: increased risk (Forrest Ia to IIc) or low risk (Forrest III)...

Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital with a gastric submucosal tumor. The tumor was observed in the antrum of the stomach. It was preoperatively diagnosed as a schwannoma after immunohistochemical evaluation of a biopsy specimen, obtained using endoscopic ultrasound-guided fine needle aspiration...

Early gastric cancer (ECG) can be difficult to diagnose endoscopically. Endoscopists should be familiar with subtle changes and endoscopic features of EGC. Chromoendoscopy and image-enhanced endoscopy improve diagnostic accuracy and facilitate endoscopic resection. Endoscopic submucosal dissection is a preferred endoscopic technique for resection of EGC and offers a comparable overall survival to surgical resection. Endoscopic management of benign gastric epithelial polyps (fundic gland polyps, hyperplastic polyps, and gastric adenoma) depends on patient symptomatology, patient's comorbidities (eg, familial syndromes), lesions' characteristics, and risk of malignant transformation...

BACKGROUND: Endoscopic submucosal dissection (ESD) is not considered an appropriate treatment for undifferentiated early gastric cancer (UEGC) due to the higher risk of nodal metastases. We aimed to investigate predictive factors for nodal metastases in UEGCs, determine whether the tumor histology is an independent factor for it, and explore whether ESD is applicable for UEGC. METHODS: We reviewed the medical records of 1837 patients who underwent curative gastrectomy for poorly differentiated adenocarcinoma, signet ring cell carcinoma, and a mixed type of both tumors between 2008 and 2012...

Use of endoscopic submucosal dissection (ESD) technique has been widespread. However, ESD of lesions in the duodenum is technically more challenging than ESD in other parts of the GI tract because it is difficult to keep the submucosal layer lifted. Therefore, the procedure is associated with severe complications, such as delayed bleeding and perforation. [1] We present a case of duodenal ESD in which traction method was used with an S-O clip (Zeon Medical Co., Ltd., Tokyo, Japan) (Figure 1) [2] to visualize the submucosal layer clearly...

BACKGROUND AND AIMS: Mucosal lift is critical for successful endoscopic treatment. Normal saline solution (NS) is widely used as the submucosal filler, but its short persistency restricts clinical endoscopic submucosal dissection (ESD) procedure. In this study, thermo-sensitive isopentane was introduced for submucosal injection. With a 27.8°C boiling point, liquid isopentane could be easily applied, whereas gasification inflation could provide great support for submucosal lifting at body temperature...

In past years, the cell-sheet construct has spurred wide interest in regenerative medicine, especially for reconstructive surgery procedures. The development of diversified technologies combining adipose tissue-derived stromal cells (ADSCs) with various biomaterials has led to the construction of numerous types of tissue-engineered substitutes, such as bone, cartilage, and adipose tissues from rodent, porcine, or human ADSCs. Extended esophageal endoscopic submucosal dissection (ESD) is responsible for esophageal stricture formation...

Esophagogastric cancer accounts for the second most common cause of cancer-related mortality worldwide. Significant efforts have been made to detect these malignancies at an earlier stage through the implementation of screening programs in high-risk individuals using advanced diagnostic techniques. Endoscopic management techniques, such as endoscopic mucosal resection and endoscopic submucosal dissection, have consistently demonstrated excellent outcomes in the management of these lesions. These techniques are associated with a lower risk of morbidity and mortality when compared with traditional surgical management...
