Although there were differences in the frequency of occurrence, various adverse reactions were confirmed in using all 4 COVID-19 vaccines, even with the BNT162b2 (Pfizer-BioNTech) vaccine. Caution is needed, and further research should be continuously conducted.

Obesity, visceral adiposity, and sarcopenia showed additive effects on MS prediction. Subjects with obesity, visceral adiposity, or sarcopenia were significantly associated with the increased risk of MS after adjustment for multiple confounders. Increasing skeletal muscle and reducing visceral fat may be strategies for the prevention or treatment of MS.

CCL28 could be useful for diagnosing UC. However, further validations of CCL28 on disease activity and severity are needed.

Non-Hodgkin lymphoma involving the esophagus is very rare. Only a few cases have been reported in the English literature to date, and it accounts for less than 1% of all cases of gastrointestinal lymphoma. As this malignancy manifests as a submucosal tumor, pathological diagnosis by using a simple endoscopic biopsy alone is difficult. Therefore, surgical biopsy, endoscopic mucosal resection, and endoscopic ultrasound-guided fine-needle aspiration have been used in most cases. Herein, we report a

Gastric cancer patients with acute disseminated intravascular coagulation experiences a rare but severe complication resulting in a dismal prognosis. We report a case of advanced gastric cancer complicated with disseminated intravascular coagulation with intractable tumor bleeding which was successfully treated with chemotherapy consisting of 5-fluorouracil and oxaliplatin. The patient was a 63-year-old man who complained of abdominal pain, melena, and dyspnea on 24 November 2010. We diagnosed s

Gastroparesis following radiofrequency catheter ablation (RFCA) is a very rare complication, as only two cases have been reported in the English literature. A 42-year-old man underwent RFCA due to recurrent drug-resistant symptomatic atrial fibrillation. The patient complained of indigestion and early satiety 2 days after the procedure. Contrast-enhanced computed tomography and an upper gastrointestinal series of the abdomen showed a large amount of material remaining in the stomach area. All fo

Regional lymph node enlargement on abdominal CT scan in patients within expanded criteria for ESD of ECG may be not due to metastasis but a reactive change.

We have developed a new ESD simulator that can help beginners achieve a high level of technical experience before performing real-time ESD procedures in patients.

Background/Aims: We used 3-dimensional (3D) printing technology to create a new hemostasis simulator for the stomach and investigated its efficacy and realism in endoscopic hemostasis training. Methods: A new stomach hemostasis simulator, with two hemostasis modules for hemoclipping and injection, was constructed using a 3D printer. Twenty-one endoscopists, including 11 first-year fellows (beginner group) and 10 faculty members (expert group), tested the performance of the simulator. We recorded

This preliminary study shows that guidetube-assisted endoscopic procedures are faster, easier, safer and cheaper than conventional endoscopic procedures.

There are many reports about causes of corrosive agents such as acids and alkaline and occasionally hot food in either liquid or solid forms as causes of upper gastrointestinal mucosal injury. However, there have been no reports on bowel preparation solutions as a cause of upper gastrointestinal injury. We describe a case of bowel preparation solution (PICOLIGHT powder) induced thermal injury of the gastric mucosa with a review of the literature. (

Droplets released from the mouth of a COVID-19 infected patient are an important source of infection [1]. Currently, gastrointestinal (GI) endoscopy preventative guidelines have been developed based on cough models with droplet travel distances of over 2 m [2] [3] [4] [5] [6]. However, the droplet-related studies reported so far have mostly focused on cough models related to respiratory disease. Thus far, no studies have been conducted on droplets generated during GI endoscopic examinations.
