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)...

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...

A nonresonant, femtosecond (fs) laser is employed to desorb samples of Victoria blue deposited on stainless steel or indium tin oxide (ITO) slides using either electrospray deposition (ESD) or dried droplet deposition. The use of ESD resulted in uniform films of Victoria blue whereas the dried droplet method resulted in the formation of a ring pattern of the dye. Laser electrospray mass spectrometry (LEMS) measurements of the ESD-prepared films on either substrate were similar and revealed lower average relative standard deviations for measurements within-film (20...

In Nigeria, a large number of radiographic examinations are conducted yearly for various diagnostic purposes. However, most examinations carried out do not have records of doses received by the patients, and the employed exposure parameters used are not documented; therefore, adequate radiation dose management is hindered. The aim of the present study was to estimate the dose-area product (DAP) of patients examined in Nigeria, and to propose regional reference dose levels for nine common examinations (chest PA, abdomen AP, pelvis AP, lumbar AP, skull AP, leg AP, knee AP, hand AP, and thigh AP) undertaken in Nigeria...

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...

OBJECTIVES: Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. METHODS: We performed a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at our hospital...
