Abstract    The progress of surgical techniques and surgical instruments has brought a variety of innovation for gastric surgery. The causes of postoperative digestive tract obstruction also become diversified，involving primary disease，choice of procedure，anastomosis method and other factors. Anastomotic stenosis or obstruction after gastrectomy mainly occurs in stomach-duodenum，stomach-jejunum，esophagus-jejunum, esophagus-residual stomach and other anastomosis，closely related to the selection of anastomosis, procedures and instruments，scar or tumor relapse. The afferent loop and efferent loop obstruction are still one of the important complications. It is more afferent loop obstruction in clinic. The Roux limb of Roux-en-Y anastomosis may also have some unique obstructions, such as intussusception，internal hernia，Roux stasis syndrome. In addition，gastric paralysis or adhesive intestinal obstruction may also occur. Therefore，with the changes in disease spectrum and the development of gastrointestinal surgery，the causes and characteristics of digestive tract obstruction after gastrectomy have undergone great changes. Surgeons need to carry forward the artisan spirit，strive for excellence，and constantly sum up clinical experience.
