Although the incidence of gastric cancer has decreased worldwide compared to the past, the incidence of esophagogastric junction cancer and upper 1/3 gastric cancer is gradually increasing. Currently, the main treatment for esophagogastric junction cancer and upper gastric cancer is surgery. However, there is no clinical consensus on the choice of surgical approach for these patients. Compared with total gastrectomy, proximal gastrectomy can preserve the physiological function of the stomach and has great advantages in nutrient absorption, thus it has been widely accepted in Asian countries.\n\nHowever, the risk of developing reflux esophagitis after proximal gastrectomy is high, which seriously affects patients' postoperative quality of life. In order to reduce the occurrence of postoperative complications, clinicians continue to improve the methods of GI reconstruction. Currently, the common methods of GI reconstruction after proximal gastrectomy include esophagogastrostomy (EG), jejunal intubation (JI), jejunal pouch intubation (JPI), and dual-tract reconstruction (DTR). However, the choice of the optimal reconstruction method after proximal gastrectomy remains controversial, and there is no standard approach to GI reconstruction. In 2016, Kuroda et al. reported a new surgical approach with a double-flap technique after proximal gastrectomy and showed satisfactory short-term outcomes compared with conventional esophagogastric anastomosis. At the 1-year postoperative follow-up, no reflux esophagitis was detected in all patients. At the same time, the rate of anastomotic stenosis was noteworthy.\n\nThis study will be the first attempt at a left-open single-flap technique, which was modified from the double-flap technique. The short-term outcome was satisfactory in all patients. This study will establish a large sample, multicenter randomized clinical study. By exploring a simple, safe, good absorption and digestive function method of post-proximal gastrectomy reconstruction to improve patients' postoperative quality of life and fill the gap in the comparison of clinical efficacy between left-open single-flap technique and double-flap technique in this specialized field. This will promote the establishment and improvement of the specifications related to gastrointestinal reconstruction."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria\n\n1.
