Comparison Between Double Tract Anastomosis and Esophagogastrostomy After Radical Proximal Gastrectomy

Comparison Between Double Tract Anastomosis and Esophagogastrostomy After Radical Proximal Gastrectomy: A Prospective, Randomized, Controlled Study

The patients with upper gastric cancer (cT1N0M0) or gastroesophageal adenocarcinoma (diameter less than 4 cm) will be enrolled into this study. Each of these patients will undergo radical proximal gastrectomy and be randomly allocated into one of the two groups, double tract anastomosis group or esophagogastrostomy group. The following data will be collected to compare the difference between the two reconstruction methods: the rate of reflux esophagitis, postoperative quality of life, economic expenditure, the safety of operation, postoperative recovery, postoperative nutrition status and oncological effect. Through the comprehensive analysis, the result of this study will elucidate the best of the reconstruction method after proximal gastrectomy.

After the proximal gastrectomy, the purse-string suture is tied at the esophagus stump, and the anvil head is inserted into the esophagus stump using an anvil clamp. A Roux-en-Y esophagojejunostomy (E-stomy) is performed by intracorporeal anastomosis with a circular stapler, and the jejunal stump is closed with a linear stapler. Next, side-to-side gastrojejunostomy (G-stomy), 15 cm below the E-stomy, is performed using 2 linear staplers. Finally, end-to-side jejunojejunostomy (J-stomy), 20 cm below the G-stomy, is performed by 2 linear staplers.

After the proximal gastrectomy, the purse-string suture is tied at the esophagus stump, and the anvil head is inserted into the esophagus stump using an anvil clamp. Next, end-to-end or side to end esophagogastrostomy is performed with a circular stapler.

The rate of reflux esophagitis after operation will be assessed by gastrointestinal endoscopy with Los Angeles (LA) classification. the degree of reflux esophagitis will be classified as N, A, B, C or D level, and latter levels represent a more severe reflux esophagitis.

Assessed by European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ) - C30 questionnaire, the total score ranges from 30 to 126, and higher values represent a worse outcome.

Assessed by European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ) - STO22 questionnaire, the total score ranges from 22 to 88, and higher values represent a worse outcome.
