First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at whether the amount of three types of bacteria in stool samples is linked to gallbladder cancer risk. Researchers compared 230 South American patients with gallstones, some who had gallbladder cancer and some who did not. The goal was to confirm earlier findings that certain bacteria levels differ between the two groups. This is an observational study, not a treatment.
