Omental preservation versus omentectomy in curative-intent gastrectomy for gastric cancer : Swedish population-based cohort study
BACKGROUND: Omentectomy has traditionally been performed in gastric cancer surgery, but omental preservation has become increasingly common. It is unclear whether omentectomy leads to additional survival benefit compared with omental preservation. This nationwide population-based cohort study aimed to assess survival and surgical outcomes comparing omental preservation to omentectomy in curative-i
