In total gastrectomy done for gastric cancer

In total gastrectomy done for gastric cancer, why do we do oesophagojejunostomy and not oesophagoduodenostomy since we are only removing stomach till pylorus of stomach…

Duodenum is not mobile

The duodenum is not connected directly to the esophagus or remaining stomach to prevent bile reflux and complications such as gastric ulcer and /or cancer at the site of anastomosis

thank you so much sir

No need to study if u are UR bro
