A Prospective Study on Esophagogastrostomy by an Innovative Surgical Technique

"Surgical Operation:~1. Gastric Resection Range:Proximal gastrectomy, preserving 2/3 of the distal stomach.~2. Lymph Node Dissection Range:D1+ to D2 lymph node dissection.~3. Anastomosis Method: esophagogastrostomy by fissure technique.~4. Anastomosis Risk Management Plan:For a rupture with a maximum diameter less than or equal to 5mm, repair with 4-0/3-0 absorbable sutures and proceed with the anastomosis.For a rupture with a maximum diameter greater than 5mm or failed anastomosis, resect that part of the remaining stomach, change to proximal gastrectomy, and perform double-channel anastomosis.~5. Surgical Approach:Totally laparoscopic proximal gastrectomy."
