In the surgical treatment of pancreatic cancer with residual gastric esophagus, residual gastric, jejunal and colonic substitution for esophagus are the three methods in the quintessence. Rectal Roux_y, transverse colon cis-peristaltic substitution for esophagus is the conventional treatment that should be strived for clinically, while residual gastric substitution for esophagus is one of the methods with more variables. A sufficiently large residual stomach can be made into a gastric tube after radical resection of the tumor in a clinical setting, which undoubtedly reduces the difficulty and risk. In some cases, the lower part of the residual stomach and esophagus can be anastomosed under the arch and the spleen can be considered to be moved into the thoracic cavity, which is a wise move on the operating table and can solve the problem of serious jejunal and colonic adhesions that cannot be freed. In conclusion, it is important to be flexible and resourceful on the table of unconventional surgery such as residual gastroesophageal cancer cardia cancer, and it is a win-win strategy to simplify the originally complicated surgery.
