title: Preoperative embolization therapy for esophageal operation.
abstract: OBJECTIVE
  Since 1993, we have performed preoperative embolization therapy (PET) in an attempt to augment the blood flow of the gastric tube and prevent anastomotic leakage after esophageal resection. The clinical effects and complications associated with PET are reported.
  
  
  METHODS
  The femoral artery was punctured and the left gastric artery, right gastric artery, and splenic artery underwent embolization, leaving the right gastroepiploic artery as the only patent feeding artery for the stomach. PET was performed in 54 patients, and data concerning blood flow of the stomach before and after the construction of the gastric tube were available in 51 patients. Of the 25 patients who were operated in the same period without undergoing PET, similar data were available in 20 patients.
  
  
  RESULTS
  In the group of patients who underwent PET, the blood flow of the gastric tube after its construction was 67% of the value measured at the upper part of the stomach just after opening the abdominal cavity. For those who were not pretreated by PET, it declined to 33%.
  
  
  CONCLUSIONS
  PET for esophageal cancer is a safe procedure that contributes to the decrease in the frequency of anastomotic dehiscence after esophageal operation, owing to the augmented tissue blood flow of the upper portion of the stomach following the construction of gastric tubes.
