Comparison of effects of six main gastrectomy procedures on patients' quality of life assessed by Postgastrectomy Syndrome Assessment Scale-45.

BACKGROUND

The effects of various gastrectomy procedures on the patient's quality of life (QOL) are not well understood. Thus, this nationwide multi-institutional cross-sectional study using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), a well-established questionnaire designed to clarify the severity and characteristics of the postgastrectomy syndrome, was conducted.

AIM

To compare the effects of six main gastrectomy procedures on the postoperative QOL.

METHODS

Eligible questionnaires retrieved from 2368 patients who underwent either of six gastrectomy procedures [total gastrectomy with Roux-en-Y reconstruction (TGRY; = 393), proximal gastrectomy (PG; = 193), distal gastrectomy with Roux-en-Y reconstruction (DGRY; = 475), distal gastrectomy with Billroth-I reconstruction (DGBI; = 909), pylorus-preserving gastrectomy (PPG; = 313), and local resection of the stomach (LR; = 85)] were analyzed. Among the 19 main outcome measures of PGSAS-45, the severity and characteristics of postgastrectomy syndrome were compared for the aforementioned six gastrectomy procedures using analysis of means.

RESULTS

TGRY and PG significantly impaired the QOL of postoperative patients. Postoperative QOL was excellent in LR (cardia and pylorus were preserved with minimal resection). In procedures removing the distal stomach, diarrhea subscale (SS) and dumping SS were less frequent in PPG than in DGBI and DGRY. However, there was no difference in the postoperative QOL between DGBI and DGRY. The most noticeable adverse effects caused by gastrectomy were meal-related distress SS, dissatisfaction at the meal, and weight loss, with significant differences among the surgical procedures.

CONCLUSION

Postoperative QOL greatly differed among six gastrectomy procedures. The severity and characteristics of postgastrectomy syndrome should be considered to select gastrectomy procedures, overcome surgical shortcomings, and enhance postoperative care.
