Ex lap stands for exploratory laparotomy - a surgical procedure to investigate the abdominal organs. In this case, we were looking for a cause of vomiting. When young Bonnie came in to see us she was very unwell - vomiting and not herself. Diagnostic radiographs revealed abnormalities in her stomach. We surgically opened her stomach and found that she had ingested a lot of gravelly material as well as a rock! Bonnie is now all healed and back to her energetic self.
