Preoperative oesophagogastroduodenoscopy (OGD) in bariatric surgery remains a controversial topic, with a large variety in practice globally. An electronic database search of Medline, Embase and PubMed was performed in an aim to categorise the findings of preoperative endoscopies in bariatric patients. A total of 47 studies were included in this meta-analysis resulting in 23,368 patients being assessed. Of patients assessed, 40.8% were found to have no novel findings, 39.7% had novel findings which did not affect surgical planning, 19.8% had findings that affected their surgery and 0.3% were ruled to not be suitable for bariatric surgery. Preoperative OGD is altering surgical planning in one-fifth of patients; however, further comparative studies are required to determine if each patient should undergo this procedure especially if asymptomatic.
