Evaluation of postgastrectomy symptoms and daily lives of small remnant distal gastrectomy for upper-third gastric cancer using a large-scale questionnaire survey.

AIM

Total gastrectomy (TG) is often performed for proximal gastric cancer. Small remnant distal gastrectomy (SRDG) can also be used in cases where surgical margins can be secured. The impact of preserving proximal small remnant stomach on postoperative quality of life (QOL) has not been fully elucidated. In the present study, we compared postgastrectomy symptoms and daily lives between patients undergoing SRDG and those undergoing TG for proximal gastric cancer using the developed Postgastrectomy Syndrome Assessment Scale (PGSAS)-45.

METHODS

Of the 1909 patients enrolled in the PGSAS NEXT study, univariate analysis of 19 main outcomes measures (MOMs) of PGSAS-45 was performed in patients undergoing TG (n = 1020) or SRDG (n = 54). Multiple regression analysis was performed with several clinical factors as explanatory variables.

RESULTS

There was no difference in age and sex between TG and SRDG groups. In SRDG group, postoperative period was shorter, the rates of laparoscopic approach and preservation of the celiac branch of the vagus nerve were higher, and the rates of clinical stage III/IV disease, ≥D2 dissection, and combined resection with other organs were lower than in the TG group significantly ( < .05). SRDG was associated with significantly lower symptoms and better daily lives than TG in 12 and 13 of 19 MOMs in PGSAS-45 by univariate and multiple regression analyses, respectively ( < .05). Several other clinical factors were also associated with certain MOMs.

CONCLUSION

The PGSAS-45 revealed that SRDG was associated with better postgastrectomy symptoms and daily lives than TG.
