Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Postoperative nausea and vomiting (PONV) was one of the common complications in patients with HCC who had undergone TACE. This study was a prospective analysis of patient data to investigate risk factors for PONV in patients after TACE. Data were collected from 212 patients undergoing TACE in the interventional department between August 2022 and August 2023.

Background: Endoscopic diagnosis of early gastric cancer (EGC) is a challenge. It is not clear whether deep convolutional neural network (DCNN) model could improve the endoscopists' diagnostic performance.
Methods: We established a DCNN-assisted system and found that accuracy of diagnosis is higher than endoscopists.

Autoimmune gastritis (AIG) is a chronic condition in which the body's immune system mistakenly attacks the stomach lining, specifically targeting parietal cells that produce stomach acid and intrinsic factors. After the infection was eradicated, AIG developed in an elderly woman with symptoms of the disease. 1.

MedStar Health Internal Medicine Residency Program, Baltimore, MD, USA.
Gastric Linitis plastica is characterized by extensive infiltration of gastric wall by poorly differentiated tumor cells, creating a "leather-bottle stomach" appearance. We describe a case involving a 71-year-old male presenting with globus sensation, early satiety and weight loss. Recent EGD had revealed chronic gastritis with polypoid mucosa at the GE junction, and subsequent FDG-PET indicated asymmetric FDG localization.
