为克服传统的胃大部切除术因缺失幽门而致的倾倒征、胆汁返流等并发症,作者设计使用相当于正常幽门口径的小吻合口、胃粘膜瓣、套入式一层吻合、带蒂胃浆肌瓣4项技术,革新再造幽门来完成胃大部切除术的胃十二指肠吻合。实验分两个阶段,前阶段共作8只狗,主要摸索浆肌瓣、粘膜瓣的制作方法及 To overcome the traditional complications of gastrectomy due to the absence of pylorus, such as dumping signs and bile reflux, the authors designed a small anastomosis, gastric mucosal flap, nested anastomosis, and band The four techniques of pedicled musculoskeletal flaps have revolutionized the reconstruction of the pylorus to complete a gastroduodenal anastomosis for subtotal gastrectomy. The experiment was divided into two phases. There were a total of 8 dogs in the previous phase. The main method was to explore the preparation method of plasmonic muscle flaps and mucosal flaps.
