RESUMO
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; n = 393), proximal gastrectomy (PG; n = 193), distal gastrectomy with Roux-en-Y reconstruction (DGRY; n = 475), distal gastrectomy with Billroth-I reconstruction (DGBI; n = 909), pylorus-preserving gastrectomy (PPG; n = 313), and local resection of the stomach (LR; n = 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.
RESUMO
BACKGROUND: Proximal gastrectomy with esophagogastrostomy (PGEG) has been widely applied as a comparatively simple method. In this study, we used a questionnaire survey to evaluate the influence of various surgical factors on post-operative quality of life (QOL) after PGEG. METHODS: In this post-gastrectomy syndrome assessment study, we analyzed QOL in 2,368 cases. Among these, 193 had undergone proximal gastrectomy and 115 had undergone PGEG. The Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 is a questionnaire consisting of 45 items, including the SF-8, the Gastrointestinal Symptom Rating Scale (GSRS), and other symptom items seemed to be specific to post-gastrectomy. The 23 symptom items were composed of seven symptom subscales (SS), including esophageal reflux, abdominal pain, and meal-related distress. These seven SS, total symptom score, ingested amount of food per meal, necessity for additional meals, quality of ingestion SS, ability to work, dissatisfaction with symptoms, dissatisfaction with the meal, dissatisfaction with working, dissatisfaction with daily life SS and change in body weight were evaluated as main outcome measures. In PGEG cases, we evaluated the influence on QOL of various surgical factors, such as procedures to prevent gastroesophageal regurgitation and size of the remnant stomach. RESULTS: The scores for esophageal reflux and dissatisfaction with the meal were higher in patients who had not undergone an anti-reflux procedure. In most cases, the preserved remnant stomach was more than two-thirds the size of the pre-operative stomach. When comparing patients with a remnant stomach two-thirds the pre-operative size and those with more than three-quarters, the diarrhea SS and necessity for additional meals scores were lower in the group with more than three-quarters. The indigestion, constipation, and abdominal pain subscales, and the total symptom score, were higher in patients who had not undergone pyloric bougie than in those who had. CONCLUSION: These results indicated that QOL was better in patients with a large remnant stomach. Procedures to prevent gastroesophageal reflux, and the use of pyloric bougie as a complementary drainage procedure, were considered effective ways to reduce the deterioration of QOL.
