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.
This study is a prospective, multi-center randomized controlled study. Patients with advanced distal gastric cancer with outflow tract obstruction ( clinical stage T4bN + M0 / T3-4N + M1, stage IV ) were enrolled. The outflow tract obstruction was confirmed by upper gastrointestinal angiography. Patients who underwent gastrojejunostomy after preoperative evaluation. After enrollment, the patients were randomly divided into SPGJ group or CGJ group according to the ratio of 1 : 1 by random number table. This study was designed for evaluators ' blinding. Imaging experts who are responsible for determining the primary endpoint ( delayed gastric emptying classification, GOOSS score ), researchers who are responsible for collecting patient-reported outcomes ( such as quality of life questionnaires ), and statisticians who perform final data analysis will be unaware of the patient 's grouping information. This study was divided into four stages : screening period, operation period, medical treatment period and follow-up period.

Exclusion Criteria:
At the junction of the gastric body and the antrum, or about 5cm from the upper edge of the tumor, a straight-line cutting closure device was used to cut off part of the gastric body from the greater curvature of the stomach to form a partition, and a 2-3cm wide gastric body near the lesser curvature was retained. A hole was made in the greater curvature of the posterior gastric wall at the proximal end of the septum, and a hole was made in the jejunum-to-mesenteric margin 5-10 cm from the Treitz ligament. A linear cutting closure device was placed through the transverse colon. The greater curvature-jejunum side-to-side anastomosis of the posterior gastric wall with pro-peristalsis or anti-peristalsis was performed, and the common opening was closed by using a linear cutting closure device or suture.
Procedure: stomach-partitioning gastrojejunostomy
The lowest point of the greater curvature of the stomach and the proximal jejunum 5-10 cm away from the Treitz ligament were subjected to side-to-side anastomosis of peristaltic or anti-peristaltic using a linear cutter before the transverse colon, and the common opening was closed using a linear cutter or suture.
Procedure: conventional gastrojejunostomy
At the junction of the gastric body and the antrum, or about 5cm from the upper edge of the tumor, a straight-line cutting closure device was used to cut off part of the gastric body from the greater curvature of the stomach to form a partition, and a 2-3cm wide gastric body near the lesser curvature was retained. A hole was made in the greater curvature of the posterior gastric wall at the proximal end of the septum, and a hole was made in the jejunum-to-mesenteric margin 5-10 cm from the Treitz ligament.

Incidence of delayed gastric emptying（DGE）
Percentage of patients with delayed gastric emptying after surgery
Time frame: Evaluation time of delayed gastric emptying : day 3, day 7, day 14, day 21.after operation.
PG-SGA score
PG-SGA assessment table contains seven aspects, which are divided into two parts : the patient self-assessment part ( A score ) and the medical staff assessment part ( B + C + D score ). The total score is obtained by adding the two parts.
Time frame: Approximately 30 days
Early postoperative complication rate
The probability of complications within 21 days after surgery ( including prolonged hospital stay and rehospitalization ).
Time frame: Within 21 days after surgery
Late postoperative complication rate
Probability of complications 21 days after surgery
Time frame: 21 days after operation
Anastomotic complication rate
The probability of postoperative anastomotic complications including anastomotic stenosis and anastomotic bleeding.
Time frame: Within 21 days after surgery
postoperative mortality
The probability of death within 90 days after surgery, regardless of the cause of death after surgery.
Time frame: Within 90 days after surgery
Overall survival ( OS )
Overall survival time from surgery to death of any cause
Time frame: Approximately weeks 1 - 2 after surgery
Life quality evaluation (QLQ-c30）
The QLQ-C30 ( core scale ) had a total of 30 items, using a 4-level score ( 1-4 points ). After standardization, the score range of each dimension was 0-100. The higher the score, the better the quality of life ( functional dimension ) or the more severe the symptoms ( symptom dimension ).
Time frame: Before operation and 1 week, 2 weeks, 4 weeks after operation and before the first systematic treatment after operation.
quality of life （QLQ-STO22）
QLQ-STO22 ( gastric cancer-specific module ) uses a 5-level score ( 1-5 points ). The higher the score, the more severe the symptoms or the worse the quality of life.
Time frame: Before operation and 1 week, 2 weeks, 4 weeks after operation and before the first systematic treatment after operation.
