In the multivariate analysis, only WGA-positive classification (odds ratio 2.78, 95% confidence interval 1.16-6.67; P=0.02) was a significant independent risk factor for SMGC. Our exploratory study showed the possibility of WGA as a predictive factor for SMGC. In cases of WGA-positive gastric cancer, careful examination might be needed to diagnose SMGC.

Preoperative esophagogastroduodenoscopy (EGD) may affect the management of bariatric patients although this is not consistent universally. The present prospective study evaluated the effect of preoperative EGD findings in obese Saudi patients, including upper digestive symptoms (UDS) and comorbidities, on their planned surgery. From January 2018 to May 2019, we conducted a 4-center retrospective observational study to evaluate the endoscopic findings among Saudi patients aged 18-65 years with a body mass index (BMI) >40 kg/m . Preoperative data included UDS, comorbidities, ( ) infection assessed during a histopathological examination, and EGD findings. 717 patients underwent EGDs, and 432 underwent bariatric surgery. The mean BMI was 44.3±6.3 kg/m , and the mean age was 27.8±11.8 years. The overall UDS prevalence was 49%, with the most frequent being gastroesophageal reflux disease 54% (387/717), followed by dyspepsia 44% (315/717). infection was detected in 287/672 (42.4%) patients. The total percentage of patients with normal EGD was 36% (258/717). A delayed bariatric procedure was perform
