A comparison of the effects of anti-reflux procedures during esophagogastrostomy after proximal gastrectomy on the postoperative quality of life.

PURPOSE

To investigate the postoperative quality of life (QOL) in patients with proximal gastric cancer (PGC) or esophago-gastric junction cancer, a nationwide multi-institutional study (PGSAS NEXT trial) was conducted.

METHODS

Patients who had undergone radical resection more than 6 months previously were enrolled from 70 Japanese institutions between July 2018 and June 2020. The Postgastrectomy Syndrome Assessment Scale (PGSAS)-45 questionnaire was distributed to eligible patients, and responses were collected by mail. The main outcome measures of the PGSAS-45 were then calculated and compared.

RESULTS

Questionnaires were retrieved from 1950 participants, and data from 300 patients who had undergone a proximal gastrectomy (PG) with esophagogastrostomy for PGC were analyzed. The mean esophageal reflux subscale value was 1.9 among the 276 patients who underwent an anti-reflux procedure, which was significantly better than the mean value (2.6) for the 21 patients who did not undergo an anti-reflux procedure (p = 0.002). The esophageal reflux subscale values were also compared among 3 major anti-reflux procedures: the double-flap technique (N = 153), the pseudo-fornix and/or His angle formation (N = 67), and fundoplication (N = 44); no statistically significant differences were observed.

CONCLUSION

An anti-reflux procedure during esophagogastrostomy after PG for PGC is necessary to improve postoperative esophageal reflux symptoms, regardless of the type of procedure.

TRIAL REGISTRATION
