Proximal gastrectomy

Proximal gastrectomy removes the upper portion of the stomach (shaded region in panel A between line 1 and line 2) and anastomoses the distal esophagus to a loop of jejunum in an end-to-side fashion (esophagojejunostomy [EJ]). Gastrointestinal continuity is then restored with either a jejunojejunostomy (JJ) in the standard Roux-en-Y reconstruction (panel B) or with a gastrojejunostomy (GJ) and a jejunojejunostomy (JJ) in the so-called "double-track" reconstruction (panel C).
