Core Tip

Core tip: We determined the influence of each background factor on postgastrectomy syndromes (PGS) for each gastrectomy type in 2368 patients from the PGS assessment study (PGSAS) dataset. The postoperative period, age, and sex affected PGS, and their influence varied with gastrectomy type. PGS after distal gastrectomy and pylorus preserving gastrectomy were highly affected, whereas that after total gastrectomy, proximal gastrectomy, and local resection was not. Worse PGS were observed in females, whereas a longer postoperative period alleviated some of the PGS. Laparoscopic surgery and celiac branch preservation can improve PGS in patients undergoing distal gastrectomy and pylorus preserving gastrectomy.
