BACKGROUND/AIMS: The purpose of the study was to determine the blood supply of stumps of mobilized esophagus. METHODOLOGY: Esophageal stumps of five groups of rabbits were studied. The esophageal stumps were dyed via intravenous injection of trypan blue, and were analyzed by color image processing. RESULTS: The dyed length of the esophageal stump was 7.15 ± 0.5 cm in the stomach-connecting group; 4.6 ± 0.69 cm in the stomach-connecting with myotomy group; 6.1 ± 0.88 cm in the distal stomach-connecting group; 3.0 ± 0.47 cm in the neck-connecting group; and, 2.1 ± 0.2 cm in the neck-connecting with myotomy group. There was a significant difference in the dyed length between the stomach-connecting and neck-connecting groups (p = 0.000), and between the stomach-connecting and stomach-connecting with myotomy groups (p = 0.026), but there was no significant difference between the neck-connecting and neck-connecting with myotomy (p = 0.094), or the stomach-connecting and distal stomach-connecting groups (p = 0.053). CONCLUSIONS: Stumps of the mobilized esophagus in rabbits, with or without myotomy, exhibit differences in dyed length, depending on the diameter, wall thickness and location of the blood supply in the esophagus.
