Significance of resected stomach measurements in postoperative delayed gastric emptying following laparoscopic pylorus‐preserving gastrectomy

Purpose We investigated the relationship between the resected stomach measurements, the incidence of delayed gastric emptying (DGE), and food residue 1 year after surgery in patients who underwent laparoscopic pylorus‐preserving gastrectomy (PPG). Materials and Methods The DGE group included 10 patients fasting due to nausea, vomiting, abdominal distension, or remnant stomach distension on radiographs; the control group included 36 patients without these symptoms. We compared the size and length of lesser and greater curvatures of the resected stomach and endoscopic findings after 1 year. Results No significant differences were observed between groups in terms of sex, body mass index, gross type, histology, tumor progression, number of dissected lymph nodes, operating time, or blood loss. The DGE group was older, had a longer postoperative stay, and showed a smaller size and shorter greater curvature of the resected stomach than the control group (p
