Abstract 163P
Background
Dietary intake (DI) loss after gastrectomy is a serious problem for patients with gastric cancer. We compared the dietary intake after surgery in early gastric cancer patients between those receiving laparoscopic distal gastrectomy (LDG) versus conventional open distal gastrectomy (ODG).
Methods
This was a prospective, observational study enrolling patients who underwent gastrectomy for gastric cancer. Dietary intake was assessed using the food frequency questionnaire with eighty-two food items (FFQW82) at nutritional counseling before surgery and one and three months after surgery.
Results
A total of 118 patients were included. Among them, 69 (58.5%) were male, and 49 (41.5%) were female. Seventy-five (63.6%) received LDG, and 43 (36.4%) received ODG. At 1 month postoperatively, the median DI in the LDG group was 1540 (1014–-2195) kcal/day, whereas that in the ODG group was 1547 (986–-2143) kcal/day (p = 0.891). At 3 months postoperatively, the median DI in the LDG group was 1624 (1050–-2443) kcal/day, and that in the ODG group was 1652 (917–-2144) kcal/day (p = 0.749). There was no significant difference in the DI loss rate at 1 month (median: -8.2% vs. -9.3%, p=0.398) and 3 months (median: -3.2% vs. -3.7%, p=0.635) between the LDG and ODG groups.
Conclusions
Our results suggest that minimally invasive laparoscopic surgery may not prevent postoperative DI loss after distal gastrectomy. Therefore, methods other than laparoscopic surgery are needed to prevent post-gastrectomy DI loss.
