Abstract

OBJECTIVE:

This article is based on our previously reported results of irregular bowel movement and disturbances of the intestinal microbiota/environment in gastrectomized patients. A placebo-controlled, double-blind comparative study was carried out to evaluate the effects of a fermented milk beverage containing Lactobacillus casei strain Shirota (LcS) in such patients. The major evaluated factors of this article were "bowel movement" and "quality of life." The secondary evaluated factors were "fecal microbiota" and "enteric environment."

METHODS:

Of the 190 gastrectomized subjects who participated in our previously reported defecation survey, 134 subjects judged as having abnormal defecation gave consent to participate in this study. These subjects continuously ingested the test beverage containing 40 billion LcS or placebo (one bottle per day, 4 weeks).

RESULTS:

In the LcS-ingested group, among the 118 subjects who completed the tests, the assessments of the subjects were based on their division into groups based on their symptoms with our scoring system for constipation/diarrhea; although there was no significant ingestion effect in total, in the constipation group, LcS reduced the degree of constipation compared with that in the placebo group. In the diarrhea group, LcS ingestion improved diarrhea compared with that in the preingestion state. Fecal Staphylococcus level was decreased.

CONCLUSIONS:

The results suggest the possibility that the continuous consumption of LcS-fermented milk relieves irregular bowel movement in gastrectomized patients.
