The role of routine preoperative upper endoscopy in bariatric surgery: a systematic review and meta-analysis
Abstract
Background The necessity of routine preoperative esophagogastroduodenoscopy (EGD) before bariatric surgery is controversial. European guidelines recommend routine EGD while North American guidelines recommend a selective approach.Objective Perform a systematic review and meta-analysis to determine the proportion and scope of clinical findings discovered at preoperative EGD.Setting Academic hospital, Canada.Methods A search of MEDLINE, Embase, and Cochrane databases included MeSH terms "bariatric surgery," "endoscopy," and "preoperative." Inclusion criteria were any case series, cohort study, or clinical trial describing results of preoperative EGD for any bariatric surgery. Exclusion criteria were studies with<10 patients, patients<18 years of age, or revisional operations. Changes in surgical and medical management and proportions of pathologic findings were extracted and combined in a meta-analysis using the random effects model.Results Initial search identified 532 citations. Forty-eight were included after full text review. Included studies comprised 12,261 patients with a mean (SD) age of 40.5 (1.3) years and body mass index of 46.3 (1.5) kg/m(2). The majority of patients (77.1%) were female. The proportion of EGDs resulting in a change in surgical management was 7.8%. After removing benign findings with controversial impact on management (hiatal hernia, gastritis, peptic ulcer), this was found to be .4%. Changes in medical management were seen in 27.5%, but after eliminating Helicobacter pylori eradication, this was found to be 2.5%.Conclusion Preoperative EGD in average-risk, asymptomatic bariatric surgery patients should be considered optional, as the proportion of EGDs that resulted in important changes in management was low.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
