Comparison of Partial Stomach-Partitioning and Conventional Gastrojejunostomy for the Treatment of Gastric Outlet Obstruction in Advanced Gastric Cancer

Conditions
Summary
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.

Interventions
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.
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.
