８名贲门切除吻合术患者均显示食管内有明显的核素返流。对３４名食管狭窄进行了７２次扩张，并结合抗返流治疗。结果表明：（１）９１．２％狭窄解除，近期（１０天内）进食计分（０～３）从扩张前的１．１８±０．７５增至２．５９±０．６６（Ｐ＜０．００１）；远期（平均１９个月）进食计分为２．３１±０．７０，仍明显高于扩张前（Ｐ＜０．０１）。（２）８例局部注射激素，２个月后进食计分为２．５±０．５，而１９例对照组为２．１±０．５。（３）平均扩张次数为２．１±１．１次。除１例扩张后并发出血外无其它并发症。
8 cardia resection and anastomosis patients showed significant esophageal radionuclide regurgitation. Thirty-four esophageal stenoses were expanded 72 times and combined with anti-reflux therapy. The results showed that: (1) 91.2% stenosis was relieved and score of food intake (0 ~ 3) increased from 1.18 ± 0.75 to 2.59 ± 0.66 (P <0 .001). The long-term (mean 19-month) eating score was 2.31 ± 0.70, which was still significantly higher than before dilation (P <0.01). (2) 8 cases of local injection of hormones, two months after eating score 2.5 ± 0.5, 19 cases of control group was 2.1 ± 0.5. (3) The average number of expansion was 2.1 ± 1.1 times. Except for one case, there was no other complication after the expansion and bleeding.
