Objectives:
Esophagogastroduodenoscopy (EGD) is often performed to evaluate for mucosal and anatomical abnormalities before vertical sleeve gastrectomy (SG). Little is known, however, about how prebariatric EGD in adolescents influences clinical management or outcome. Our aim was to assess if an abnormal prebariatric EGD resulted in interventions or modification of bariatric surgery.
Methods:
We performed a retrospective cohort study of adolescents undergoing evaluation for bariatric surgery. We obtained demographic and anthropometric data in addition to EGD findings, biopsy pathology, gastrointestinal symptoms, and surgical outcomes. An EGD was considered abnormal if either abnormal gross findings or abnormal pathology was reported. Patients were followed until a 6-week postop visit.
Results:
Of 134 patients presenting for evaluation, 94 (70%) underwent preoperative EGD. Fifty-one (54%) had a normal EGD and 43 (46%) had EGD abnormalities including 7 with an anatomical abnormality and 36 with mild mucosal abnormalities. Among patients with EGD abnormalities, 22% received medical intervention including proton pump inhibitor (PPI) administration (n = 10) and Helicobacter pylori eradication (n = 11). GI symptoms were the only predictor of EGD abnormalities (odds ratio [OR] 4.9: 95% confidence interval [CI] 1.6-15.0; P < 0.001). No factors predicted likelihood of a post-EGD intervention. An abnormal EGD did not correlate with any postoperative complications.
Conclusions:
In this cohort of adolescents undergoing evaluation for SG, 46% had an abnormal EGD, of which 22% received a medical intervention. Symptoms were the only predictor of EGD abnormalities. Abnormal EGD findings were not associated with modification of the surgery or any adverse outcome.
