Omental dissemination of pancreatic cancer presenting as an incarcerated inguinal hernia

-A case report-

Abstract

Herein, we present a case of omental dissemination of pancreatic cancer found in an incarcerated inguinal hernia in a 66-year-old male patient. The patient was transferred to our hospital with vomiting and right groin swelling. An abdominal CT showed an incarcerated omentum in his right inguinal hernia, and pancreatic tail tumor with multiple liver metastasis and ascites. We attempted manual reduction which could not be achieved and an emergency operation was performed. In the hernia sac, a hard omental tumor was found and resected. 1,500ml of ascites was removed and a hernioplasty was performed by the iliopubic tract repair method without mesh. The histopathological diagnosis of the resected omentum revealed dissemination of pancreatic ductal adenocarcinoma. However, the patient died 11days later. Pancreatic cancer presented with incarcerated inguinal hernia has been reported to be very rare.
