Abstract
A 75-year-old man presented with bloody stool. Hemorrhagic gastric ulcer and infectious pancreatic pseudocyst was diagnosed at another hospital and the patient was transferred to our hospital for treatment. Abdominal computed tomography scan revealed infectious pancreatic pseudocyst with a pancreatic stone, pancreatic pleural effusion and subcutaneous fistula. We performed distal pancreatectomy and fistula closure with the omentum. The postoperative course was uneventful. Pancreatic pleural effusion and subcutaneous fistula are very rare. Herein, we report this case with a review of the literature.
