    Notizen: Abstract For detection of early cancer of the pancreas,endoscopic aspiration cytology of pancreatic juicewithout endoscopic retrograde pancreatography wasperformed in 64 consecutive outpatients who had symptoms or findings that suggested pancreatic disease.Patients with positive or suspicious cytologic resultsor abnormal US findings were admitted and underwentdetailed examinations. Positive and suspicious cytologic results were obtained in 2 and 10 patients,respectively. Of those with positive and suspiciouscytologic results, two, and one patient, respectively,were ultimately found to have pancreatic neoplasms. Of these three resected specimens, one was insitu carcinoma and two presented marked atypia. Allpatients were alive with no evidence of recurrence. Nofurther cases of pancreatic neoplasm were found. Complications from the procedure did notdevelop in any patient. This technique is useful in thediagnosis of early neoplasms of the pancreas, because itis simple and safe to perform for outpatients.

    Notizen: Abstract Helicobacter pylori infection of the gastricmucosal surface was investigated in patients withhamartomatous fundic polyps or hyperplastic polyps andin patients without endoscopic evidence of disease(healthy subjects). Presence of H. pylori infection wasdetermined by culture, histologic examination, and theendoscopic phenol red test. Adherence of H. pylori wasevaluated with scanning electron microscopic examination of antral biopsy specimens. Bothprevalence of H. pylori infection (P 〈 0.001) and H.pylori adherence (P 〈 0.05) were less in patientswith hamartomatous fundic polyps than in healthy subjects and patients with hyperplastic polyps.However, the percentages of plasma cells in gastricmucosa that contained IgA and of gastric epithelialcells that expressed Lewis b did not differsignificantly among the three groups. These findings suggestthat defense mechanisms against the attachment of H.pylori other than IgA or Lewis b antigen are present inpatients with hamartomarous fundic polyps.
