A 45-year-old man was admitted with hematemesis. He had undergone Whipple’s surgery 7 years previously for a 5-cm serous cystadenoma of the pancreatic head. Upon presentation, he was hypotensive (blood pressure 82/59 mmHg) and tachycardic (110 beats/min), with a hemoglobin of 6.8 g/dL. Gastroscopy revealed bleeding anastomotic varices alongside the gastrojejunal anastomosis ([Fig. 1]). Hemostasis was secured with a Boston Resolution clip ([Video 1]). Computed tomography (CT) scanning, followed by mesenteric angiography in the portal venous phase and CT arterioportography showed proximal superior mesenteric vein (SMV) occlusion, with a large collateral vein draining the small bowel into the anastomotic varices, which decompressed via the enlarged left coronary vein (LCV) into a patent portal vein ([Fig. 2]). The occluded SMV was recanalized, dilated to 8 mm, and stented with a 7 × 29-mm Omnilink stent via a transhepatic approach, thereby re-establishing antegrade flow with subsequent collapse of the collateral vein and anastomotic varices ([Fig. 3]).

Gastrointestinal bleeding is a complication reported in 2 % – 8 % of patients following a Whipple procedure [1]. Sources of upper gastrointestinal bleeding include pseudoaneurysms, pancreatic fistulas, anastomotic ulcers, and ectopic varices [2] [3] [4] [5]. We report a case of bleeding anastomotic varices that developed from mesenteric hypertension as a result of SMV occlusion following surgery. As the small bowel was solely draining back to the portal vein via a collateral vein and anastomotic varices, endoscopic glue injection into the anastomotic varices could have led to bowel ischemia. Successful stenting of the occluded SMV resulted in the re-establishment of normal hemodynamics, decompressing the anastomotic varices, and therefore preventing future bleeding episodes.
