A rare case report of successful surgical treatment of diaphragmatic pregnancy after chemotherapy

This case highlights that Kehr's sign is a crucial diagnostic clue for upper abdominal ectopic pregnancy. A systematic survey of the entire abdomen, including the diaphragm, is mandatory during laparoscopy to avoid diagnostic omission. The sequential combination of chemotherapy and surgical treatment may represent an effective strategy to minimize surgical risk and optimize outcomes for this high-risk condition.
