【摘要】 设计并进行了食管、贲门切除术中应用耐压气囊行幽门扩张的实验和临床研究。结果表明,此法将幽门环形肌纤维拉长,幽门内径增大,减少了胃排空时阻力,有效防止了术后早期胃潴留;且扩张造成的肌纤维损伤能逐渐修复,使幽门功能得到保存。对幽门扩张内径进行了讨论。认为幽门扩张法简便易行,安全可靠,值得推广。更多还原

【Abstract】 To dilate pylorus in the operation of esophageal and cardia excision,pressure airpocket was designed and used in test and clinical study The result indicated that the sphincter muscle fibers of pylorus became longer,the internal diameter of pylorus became larger,the resistance of gastric evacuation was reduced and the premature gastric retention was effectively prevented in early postoperation After operation,the dilated sphincter muscle fibers of pylorus repairing gradually and the pyloric function was protected It also discussed the suitable dilating internal diameter of pylorus and believe that air pocketing pylorodiosis is a simple safety reliable measure and is worth popularizing更多还原
