Angiography for gastrointestinal bleeding after gastrojejunostomy should investigate both the celiac and superior mesenteric arteries. This is crucial because marginal ulcers, a common cause of bleeding, can be supplied by either artery.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Gastrojejunostomy is a surgical procedure that connects the stomach to the jejunum.
  • Gastrointestinal bleeding is a potential complication following gastrojejunostomy.
  • Marginal ulcers are a common cause of bleeding after this procedure.

Observation:

  • The study reviewed angiograms of patients experiencing gastrointestinal bleeding post-gastrojejunostomy.
  • Five patients with surgically or endoscopically confirmed marginal ulcers were analyzed.
  • The vascular supply to these bleeding marginal ulcers was examined.

Findings:

  • Two marginal ulcers were supplied by jejunal branches of the superior mesenteric artery.
  • Three marginal ulcers were supplied by gastric branches of the celiac artery.

  • This indicates a dual arterial supply for bleeding marginal ulcers.

    • Implications:

    • Angiographic evaluation for gastrointestinal bleeding after gastrojejunostomy must consider both the celiac and superior mesenteric arteries.
    • Identifying the precise arterial supply is critical for effective treatment strategies.
    • This finding may alter diagnostic protocols for post-surgical bleeding.
