Background: Although proximal gastrectomy (PG) is a function-preserving surgical option, it remains unclear as to which reconstruction method can prevent reflux and maintain body composition. Methods: Patients who underwent PG at Keio University between April 2011 and November 2018 were analyzed. Changes in the subcutaneous and visceral adipose tissues were comparatively assessed before and after a year of surgery for three common reconstruction methods. We also compared the endoscopic findings of reflux esophagitis and the number of patients prescribed with proton-pump inhibitor after a year of surgery. Results: This study included 76 patients, of which 33 patients underwent esophagogastrostomy with a circular stapler (CS), 35 under double flap (DF) reconstruction, and 8 underwent double tract (DT) reconstruction. Comparing esophagogastrostomy (CS and DF) and DT showed that esophagogastrostomy could significantly preserve both subcutaneous and visceral adipose tissues (P < 0.001 and P = 0.04, respectively). However, the change in the subcutaneous and visceral adipose tissues was comparable between CS and DF. As for reflux esophagitis, DF showed the lowest incidence rate for esophagitis and the least number of patients who were prescribed a proton-pump inhibitor. Conclusion: DF is a relatively better reconstruction method for preserving fat mass and preventing reflux among the three common reconstruction methods.
