贲门形成术加胃底折叠的动物实验研究

The experimental studies of cardioplasty and total fundoplication on dogs

本文报告了贲门形成术加胃底折叠的动物实验研究,目的在于保证胃底折叠的松紧度适宜及观察这种手术的抗返流作用.结果表明采用直径1-1.2cm(?)管作支架,可以保证折叠时的松紧度.贲门形成加胃底折叠后可形成半环状的瓣膜、包绕食向末端的胃底形成“穹窿”、这在抗返流中直着重要作用,这种手术重建的括约肌抗返流功能良好,并能长期保持.本实验研究为我科设计的贲们形成术加胃底折叠治疗食管失弛缓症提供了理论依据,文中尚结合实验结果对胀气综合症的原因和预防提出了讨论.

The aims of this study are to obtain a suilablc condition for the cardioplasty with the fundoplication and an observation of the effect of the antircflux function following the operations. The results show that a suppcrting dcvicc of a round tube with 1 - 1.2 ctn diamcter is used as a guide to establish a good lovver esophageal sphinctcr(LES). The experimental ani-mais may survive very long. The pressure in the sphimcter is cvenly the same as that after the operation immediately. The gastroesophageal reflux is never occurred except intragastric pres-sure is the same as or higher than LES. The lower csophagcal high pressure zone formed is similar to the smooth muscle in the lower part of csophagus at the sile of opcralions . The new formed cardia plays an excellent role of anturc flux function . This report suggists that the cardioplasty with fundoplication is useful for the treatment of esophageal achalasia and somc other abdpminal disorders.
