摘要Background

The role of routine preoperative oesopha gogastroduodenoscopy (OGD) for all bariatric surgery candidates is controversial. We aim to investigate the prevalence of clinically significant OGD findings in a primarily Chinese obese population and identify factors that predict a normal screening OGD.

Methods

Medical records of patients who underwent primary bariatric surgery in our centre from August 2002 to December 2014 were reviewed. OGD findings were classified into two groups: group 1 consisted of normal findings and abnormal findings that would not alter the surgical plan; group 2 consisted of lesions that might delay or alter the surgical procedure.

Results

We identified 268 patients (169 female), of mean age 39.1 ± 10.8 years, mean baseline body weight 108.7 ± 6.1 kg and mean body mass index (BMI) 40.3 ± 6.1 kg/m2 for analysis. Overall prevalence of abnormal OGD findings was 51.1 %, which included gastritis (32.5 %), hiatus hernia (17.9 %), duodenitis (8.6 %) and erosive oesophagitis (7.5 %); 27.2 % had group 2 lesions. Univariate analysis revealed older age (p = 0.016), use of NSAIDs (p = 0.004) and presence of reflux symptoms (p = 0.029) as significant risk factors of group 2 lesions. On multivariate analysis, use of NSAIDs (p = 0.015) and reflux symptoms (p = 0.039) remained significant predictive factors. In the low-risk subgroup (40 years and younger, without reflux symptoms or use of NSAIDs), the prevalence of group 2 abnormalities was 18.9 %.

Conclusions

Significant endoscopic abnormalities are common among obese Chinese patients which may delay or change the surgical plan. The negative predictive value in low-risk patients was not strong. We therefore recommend routine preoperative endoscopy for all patients.
