Summary

This study looked at whether a simple CT scan before weight-loss surgery can help predict when the original surgical plan might need to change during the operation. Researchers reviewed data from 288 adults who had planned gastric bypass surgery, comparing those whose surgery changed with those whose did not. The goal was to find CT scan measurements, like liver size, that could help surgeons prepare better and reduce complications.
