Biliary reflux after cholecystectomy: a prospective study.

The authors carried out a prospective study to ascertain whether cholecystectomy itself might be the cause of duodenogastric reflux. Patients with cholelithiasis were examined and underwent the following tests: hemanalysis, gastroscopy with biopsy, 24 hour pH-metry and acetaminophen test. Twelve patients were selected. Six months after the operation the tests were repeated. All patients were asymptomatic. Hemanalysis was normal in all 12 patients and no difference was seen in the tests of 5 of the patients; however in the other 7 differences were observed in all the tests. The authors conclude that cholecystectomy helps to provoke duodenogastric reflux in predisposed patients, and that this reflux may be asymptomatic.

Ring chromosome in a patient with MEN IIA S.

Three patients with MEN IIA S belonging to the same family, which has five affected subjects in two generations, have been studied. Constitutional karyotype examination identified an extra ring chromosome in 3% of the cells in one of the affected subjects. The number of rings for each cell varied, and different evolutionary aspects of the ring, such as doubling and interlocking, were present. Furthermore, asynchronous DNA replication of doubling rings was observed. This nonhomogeneous, nonrandom chromosome abnormality found in normal tissue of patients with MEN IIA S could be indicative of sensitivity to structural alteration of some chromosome regions.
