Gastric outlet obstruction as a rare presentation of peritoneal hydatid disease: A case report

ABSTRACT Introduction and importance: Peritoneal hydatid cyst is a rare disease which transplants by eggs of Echinococcus. Peritoneal cysts are divided into primary and secondary. This case shows an unusual manifestation of peritoneal hydatid cysts, adding to the already known manifestations of this disease in medical literature. It is important because peritoneal hydatid cysts maybe life-threatening if it is not managed carefully. Case presentation: In this case, we present a patient with history of recurrent hepatic hydatid cysts who presented with symptoms of gastric outlet obstruction. CT showed multiple peritoneal cysts consisting with peritoneal hydatid cysts located at the level of stomach pylorus. Although the patient suffered from multiple surgeries for recurrent hydatid cysts, she accepted the surgical option. The patient was discharged 10 days later after a non-complicated surgery. Albendazole was recommended after surgery. Clinical discussion: The mechanism of peritoneal hydatid cysts is still unknown, but one of theories declares that microrupture can explain the disease. Conclusion: This case emphasizes the idea that peritoneal hydatid cysts should be considered even in patients presenting with atypical symptom (eg, Gastric outlet obstruction). Highlights
