在30例胃溃疡和15例十二指肠溃疡患者中,使用一种无作用的安慰剂,定期用内窥镜测量溃疡的大小。目的是要了解这两种溃疡,在开始检查时溃疡的绝对大小与在复查时未愈合溃疡的缩小之间的关系,从而了解溃疡愈合经过时间的规律。
In 30 patients with gastric ulcer and 15 patients with duodenal ulcer, an inactive placebo was used to periodically measure the size of the ulcer with an endoscope. The purpose is to understand the relationship between the absolute size of the ulcer at the beginning of the test and the reduction of unhealed ulcers at the time of review to understand the pattern of ulceration over time.
