Objective To find out some ideal reconstructions after total gastrectomy in experimental study of rat. Methods Sixty male Sprague-Dawley rats were randomly and averagely divided into 6 groups: Roux-en-Y group (RY group), proximate jejunal pouch group (PJP group), distal jejunal pouch group (DJP group), two jejunal pouchs group (TJP group), duodenumjejunal pouch interposition group (DJPI group) and laparotomy group (L group). Body weight of rats, intestinal transit distance, adaptive changes in esophagojejunostomic mucosa and morphology changes of intestine after operation were observed and compared. Results At 2 weeks after operation, body weight in each group were significantly lower than that before operation （P＜0.05）. At 4 weeks postoperatively, body weight in PJP group, TJP group and DJPI group were significantly higher than that in RY group respectively （P＜0.05）, as well as at 8 weeks. Intestinal transit distance in PJP group was shorter than that in RY group （P＜0.05）. With regard to intestinal mucosa, TJP group and DJPI group were significantly different with RY group （P＜0.05）. Interestingly, there was no difference in each group as to refluxing esophagitis （P＞0.05）. Conclusion Proximate and two jejunal pouchs Roux-en-Y esophagojejunostomy seem to be ideal procedures for digestive tract reconstruction after total gastrectomy. The jejunal pouch interposition procedure seems to be same effective to PJP and TJP, but there is no preponderance over the former.
