BACKGROUND/AIMS: The purpose of the study was to determine the blood supply of stumps of mobilized esophagus.
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.
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).
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.
背景/目的：本研究旨在确定游离食管残端的血供情况。
对五组家兔的食管残端进行研究。通过静脉注射台盼蓝对食管残端进行染色，并采用彩色图像处理进行分析。
胃吻合组食管残端染色长度为7.15±0.5厘米；胃吻合加肌切开组为4.6±0.69厘米；远端胃吻合组为6.1±0.88厘米；颈部吻合组为3.0±0.47厘米；颈部吻合加肌切开组为2.1±0.2厘米。胃吻合组与颈部吻合组之间的染色长度存在显著差异（p = 0.000），胃吻合组与胃吻合加肌切开组之间也存在显著差异（p = 0.026），但颈部吻合组与颈部吻合加肌切开组之间（p = 0.094）以及胃吻合组与远端胃吻合组之间（p = 0.053）无显著差异。
家兔游离食管残端，无论有无肌切开，染色长度均存在差异，这取决于食管血供的直径、壁厚和位置。
