This article discusses a rare case of a 29-year-old Tibetan male who experienced severe upper gastrointestinal bleeding. The patient had a history of surgery for hepatic echinococcosis and pancreatitis. Initial tests suggested a pancreatic pseudocyst, but during an emergency exploratory laparotomy, a bleeding site beneath the cardia was found, which was identified as an intra-abdominal hydatid cyst. The cyst had perforated into the stomach, causing the bleeding. Despite surgical intervention, the patient unfortunately died of shock due to a massive rehemorrhage. This case highlights the unusual complications that can arise from intra-abdominal hydatid disease and emphasizes the importance of collaboration between gastroenterologists and surgeons in identifying and treating such cases.
