Prevalence of Raspberry-type Gastric Foveolar-type Tumor in Individuals Undergoing Medical Checkups.
Objective This study was performed to clarify the prevalence of raspberry-type gastric foveolar-type tumors, along with the time-course changes in the size and clinical course. Methods The subjects were 10,663 consecutive patients who underwent a medical checkup between April 2016 and March 2022, including an esophagogastroduodenoscopy (EGD) examination and determination of Helicobacter pylori infection status (uninfected, positive, post-eradication). The presence of characteristic reddish polypoid lesions in the stomach was investigated, and a diagnosis of raspberry-type gastric foveolar-type tumor was made based on histological findings. ⋯ Furthermore, examinations of previous EGD images revealed that two-thirds of the lesions had not changed in size, while follow-up EGD findings showed that lesions ≤5 mm in size had disappeared after a biopsy procedure. Conclusion The prevalence of raspberry-type gastric foveolar-type tumors was 0.42% in H. pylori-uninfected subjects. More than half of the lesions were too small to be removed by an endoscopic biopsy.

Objective A positive hemoculture in acute cholangitis is serious, but a blood culture result cannot be obtained at the initial diagnosis and so cannot be used for the severity assessment and decision-making concerning urgent/early biliary drainage. Accordingly, a predictor for bacteremia at the initial diagnosis of acute cholangitis would be particularly useful. We investigated the association between neutrophil proportions in white blood cell counts (%Neutro) and bacteremic acute cholangitis. ⋯ A %Neutro of ≥89.7% was a predictor of a positive hemoculture in univariate (p<0.0001) and multivariate analyses (p<0.001). Patients with a %Neutro ≥89.7% needed early biliary drainage more frequently than others (30/46, 65.2% vs. 18/48, 37.5%, p=0.0063). Conclusion %Neutro is an independent predictor of bacteremia in patients with acute cholangitis and may contribute to decision-making concerning early biliary drainage.
