Modified reconstruction procedure in subtotal esophagectomy with retrosternal gastric pull up to reduce anastomotic leakage: a propensity score-matched analysis.

One risk factor for anastomotic leakage (AL) after esophagectomy with retrosternal gastric reconstruction is excessive compression of the gastric tube at the thoracic inlet. In this study, we evaluated the effect of our modified procedure to reduce AL by placing the esophagogastric anastomosis below the thoracic inlet. Between January 2008 and December 2022, 174 consecutive patients underwent subtotal esophagectomy with retrosternal gastric pull up, followed by circular stapler anastomosis in our hospitals.
