The primary goal of clinical treatment is to relieve obstruction, restore oral feeding, improve nutritional status and improve quality of life in patients with advanced gastric cancer outflow tract obstruction. At present, the common surgical treatment for relieving obstruction is traditional gastrojejunostomy. Although the operation can relieve the obstruction, there are problems such as tumor-induced bleeding, anastomotic invasion, and high incidence of delayed gastric emptying after operation. Partitioned gastrojejunostomy effectively relieves obstruction by anastomosis of a part of the stomach to the jejunum, and isolates the tumor from the anastomosis, which is beneficial to food emptying and can reduce the risk of bleeding and anastomotic invasion. The safety and efficacy of these two procedures are still controversial, mainly because previous studies were retrospective studies or included a small sample size or enrolled patients with different pathological characteristics. The purpose of this study was to compare the safety and efficacy of separated and traditional gastrojejunostomy in the treatment of advanced gastric cancer outflow tract obstruction, and to provide the best choice for the treatment of advanced gastric cancer outflow tract obstruction.
