Endoscopic injection sclerotherapy of gastric varices prior to renal surgery in an effort to prevent potential perioperative variceal bleeding: Case report

Abstract

The patient is a man in his 50s. Preoperative esophagogastroduodenoscopic examination prior to surgery for left renal cancer revealed a gastric varix that had developed due to liver cirrhosis caused by nonalcoholic steatohepatitis. Endoscopic injection sclerotherapy (EIS) was performed to prevent potential perioperative bleeding from the gastric varix. The sclerosant, 5% ethanolamine oleate containing vascular contrast agent, was directly injected into the varix under X-ray monitoring. Endoscopy performed one month after EIS and contrast-enhanced computed tomography three months after EIS showed that the gastric varices had shrunk. EIS is an effective treatment to control and prevent bleeding from gastric varices.
