Bleeding Risk Factors after Endoscopic Submucosal Dissection in Early Gastric Cancer and the Necessity of "Second-Look" Endoscopic Examination on the following Day.

Background And Aim: Hemorrhage is often encountered after endoscopic submucosal dissection (ESD). In addition to active bleeding after resection, exposed blood vessels and blood clots without active bleeding on the post-dissection ulcer floor have been recognized within our department. We consider exposed and/or observable vessel findings and clots on the ulcer floor after re-section as important risk factors for hemorrhage.

The differential expression of perilipin-2 in hepatoblastoma and its association with prognosis.

Perilipin-2, a lipid droplet (LD) coating protein, has been found to be involved in cancer progression. However, its role in hepatoblastoma (HB) is undefined. We collected 87 HB samples and the corresponding clinical data.

[A case of gastric antral vascular ectasia improved by splenorenal shunt embolization].

An 80-year-old man with chronic renal failure and a splenorenal shunt was admitted because of progressive anemia. Gastrointestinal endoscopy revealed bleeding from a gastric antral vascular ectasia (GAVE). Despite treatment with argon plasma coagulation and blood transfusions on multiple occasions, anemia caused by GAVE bleeding recurred frequently.

Sealed endoscopic full-thickness resection for gastric cancer: a pilot study in an ex vivo and in vivo porcine model.

Endoscopic full-thickness resection (EFTR) is a useful procedure that allows minimal resection of the gastric wall because the tumor can be located endoscopically. However, the procedure carries a risk of peritoneal infection or dissemination. Thus, we devised a new EFTR technique in which the serosa is sealed using a silicone sheet to prevent the escape of gastric juice.

Findings of the margin around lesions by magnifying endoscopy with narrow-band imaging in early gastric carcinoma and intestinal metaplasia.

Objective: Many endoscopists have reported their own classifications of early gastric carcinoma (EGC) using magnifying narrow-band imaging (M-NBI). However, few reports on classifying the margin around lesions by M-NBI have been published. The aim of this study was to advocate the usefulness of the demarcation area classification for the diagnosis of EGC.
