Optimal Procedures for Double Tract Reconstruction After Proximal Gastrectomy Assessed by Postgastrectomy Syndrome Assessment Scale-45.

BACKGROUND: Although double tract reconstruction after proximal gastrectomy (PGDT) is commonly performed for proximal gastric or esophagogastric junction cancer, the impact of the procedure on postoperative quality of life (QOL) has not been clarified. We aimed to clarify the optimal PGDT procedure in terms of postoperative QOL. METHODS: Postoperative QOL was analyzed in 172 patients who underwent PGDT for proximal gastric cancer and were enrolled in the PGSAS-NEXT study, a multicenter cross-sectional study in Japan (UMIN000032221), in relation to the remnant stomach size, length of interposed jejunum between the esophagojejunostomy (E-J) and jejunogastrostomy (J-G), and size of the J-G. RESULTS: The remnant stomach size was approximately one-third in 13, half in 97, and two-thirds in 60 patients. Dissatisfaction scores for symptoms, diet, work, and daily life subscales were lower in patients with a larger stomach (p < 0.05). These patients also scored better in terms of weight loss (- 13.5%, - 14.0%, and - 11.2%, respectively) and amount of food ingested per meal (52%, 62%, and 66%). The length of the interposed jejunum was ≤ 10 cm in 62 and ≥ 11 cm in 97 patients. Weight loss (- 11.3% and - 13.8%) and dissatisfaction scores were better in the ≤ 10 cm group (p < 0.05). J-G size was ≤ 5 cm in 27 and ≥ 6 cm in 135 patients. The amount of food ingested (56%, 64%) and dissatisfaction scores were better in the > 6 cm group (p < 0.05). CONCLUSIONS: Larger remnant stomach, shorter length of interposed jejunum, and longer J-G might contribute to better postoperative QOL after PGDT.

Effects of Proximal Gastrectomy and Various Clinical Factors on Postoperative Quality of Life for Upper-third Gastric Cancer Assessed using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45): A PGSAS NEXT Study.

BACKGROUND: It is important to determine the effect of clinical factors on several domains (symptoms, living status, and quality of life [QOL]) after gastrectomy to establish individualized therapeutic strategies. This study was designed to determine the factors-particularly surgical method-that influence certain domains after gastrectomy for proximal gastric cancer by using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire. METHODS: We conducted a nationwide study of PGSAS-45 questionnaire responses retrieved from 1950 (82.5%) patients from 70 institutions who had undergone gastrectomy for gastric cancer. Of these, 1,538 responses for proximal gastric cancer (1020 total gastrectomies and 518 proximal gastrectomies [PGs]) were examined. RESULTS: PG significantly and favorably affected four main outcome measures (MOMs): elderly affected 10 MOMs, male sex affected 4 MOMs, longer postoperative period affected 8 MOMs, preservation of the vagus nerve affected 1 MOM, adjuvant chemotherapy affected 1 MOM, clinical stage affected 2 MOMs, and more extensive lymph node dissection affected 2 MOMs. However, the laparoscopic approach had an adverse effect on MOMs and combined resection of other organs had no favorable effect on any MOMs. CONCLUSIONS: This PGSAS NEXT study showed that it is better to perform PG for proximal gastric cancer, even for patients with advanced cancer, to obtain favorable postoperative QOL if oncological safety is guaranteed. Because the MOMs of PGSAS-45 are positively and negatively influenced by various background factors, it also is necessary to provide personalized care for each patient to prevent deterioration and further improve symptoms, living status, and QOL postoperatively.

The evaluation of the postoperative quality of life in patients undergoing radical gastrectomy for esophagogastric junction cancer using the Postgastrectomy Syndrome Assessment Scale-45: a nationwide multi-institutional study.

PURPOSE: This retrospective nationwide survey investigated the quality of life (QOL) of patients with esophagogastric junction cancer after gastrectomy using the Postgastrectomy Syndrome Assessment Scale-45. METHODS: The Postgastrectomy Syndrome Assessment Scale-45 comprises 45 questions classified into symptoms, living status, and QOL domains. A total of 1950 gastrectomized patients with upper-third gastric or esophagogastric junction cancer returned the completed forms. Among them, 224 eligible patients with esophagogastric junction cancer were selected, including 86, 120, and 18 patients who underwent total gastrectomy, proximal gastrectomy (reconstruction-esophagogastrostomy: 56; double-tract method: 51), and other procedures, respectively. RESULTS: The postoperative period was significantly shorter (47 ± 30 vs. 34 ± 30 months, p = 0.002), and the rates of early-stage disease and minimally invasive approaches significantly higher (both p < 0.001) in the proximal gastrectomy group than in the total gastrectomy group. Despite advantageous background factors for proximal gastrectomy, the postoperative QOL did not differ markedly between the groups. Compared to patients who underwent reconstruction with the double-tract method, patients who underwent esophagogastrostomy had significantly larger remnant stomachs but a similar QOL. CONCLUSION: Even with total gastrectomy, a postoperative QOL comparable to that with proximal gastrectomy can be maintained. Clarifying the optimal reconstruction methods for proximal gastrectomy for esophagogastric junction cancer is warranted.
