A 23-year-old western lowland gorilla is back with her troop after undergoing an unusual surgery. The procedure, which included a C-section, was prompted by a miscarriage. Large cystic masses were also removed from her ovaries.

The gorilla's care team had grown concerned after noticing symptoms rarely seen in primates, including fluid buildup in her abdomen and a fetus without a heartbeat. Further details about the surgery and the gorilla's condition are available from the source, including information about the collaboration between the zoo's staff and human doctors, such as board-certified OB-GYN Jamie Erwin.
