Results of a nationwide questionnaire-based survey on nutrition management following gastric cancer resection in Japan

A study was conducted to clarify the actual status of nutrition management after gastric cancer surgery in Japan and obtain basic data for optimizing perioperative nutrition management. A questionnaire was sent to 354 hospitals with at least 50 cases of gastric cancer surgery per year. Questions included the perioperative nutrition management and length of hospital stay for patients who underwent gastric cancer surgery within three months of the survey. Responses were obtained from 242 hospitals (68%; 20,858 patients). Nutrition management was consistent between laparotomy and laparoscopic surgery for 84% of respondents. The number of postoperative days was the most commonly chosen index for starting oral feeding. The most commonly chosen index for hospital dischargeability was diet composition/amount consumed in 182 hospitals (44%), followed by laboratory data stabilization in 106 hospitals (26%), and the number of postoperative days in 87 hospitals (21%). A positive correlation was found between the mean length of postoperative hospital stay and starting oral feeding (r = 0.23 for distal gastrectomy; r = 0.34 for total gastrectomy). The length of hospital stay tended to be shorter with an earlier start of oral feeding (p < 0.01). Early postoperative oral feeding may be a factor in reducing the length of hospital stay after gastric cancer surgery.
