全胃切除术后消化道重建术式繁多，至今很难选择理想术式。空肠贮袋是临床关注的热点，根据食物是否经过十二指肠，可以将贮袋法分成Roux-en-Y基础以及间置空肠基础两大类。大多数临床研究认为贮袋可以减缓食物排空，减少倾倒综合征及反酸的发生率，增加进食量。无论食物是否经过十二指肠，建立贮袋的病人均能获得较好的生存质量，尚有待多中心、随机对照研究进一步证实。

Abstract    Various digestive tract reconstruction methods are used after total gastrectomy. But there is no optimal one. Jejunal pouch is the most common reconstruction technique. According to preserving duodenal passage, there are two types of reconstruction such as Roux-en-Y with jejunal pouch and pouch with preserved duodenal passage. Most studies show that additional pouch formation can delay employing time, decrease the incidence of dumping syndrome and water brash and increase food intake postoperatively. No matter preserving duodenal passage or not, quality of life is improved significantly in patients with a pouch compared with patients without a pouch. The multicenter, randomized clinical trials are needed to provide the further evidence.
