We herein report a 71-year-old man with pancreatic carcinoma presenting as gastric varices caused by an obstruction of the splenic vein compressed by the tumor, which also invaded the spleen, stomach, transverse colon, left kidney, and left adrenal gland. A complete resection of distal pancreatomy and lymph node dissection with splenenctomy, left adrenalectomy, left nephrectomy, and partial resection of transverse colon and stomach were performed. After the resection, the gastric varices completely disappeared without any interventional therapy. The gastric varices observed in this case were considered to be derived from left-sided portal hypertension secondary to splenic vein occlusion, which is an uncommon complication mostly associated with pancreatitis and pancreatic carcinoma. Now that 17 months have passed after his operation, the patient is alive and in satisfactory condition without any signs of recurrence.
