The role of preoperative upper endoscopy in adolescents undergoing laparoscopic vertical sleeve gastrectomy

Background: Vertical sleeve gastrectomy (VSG) has been associated with gastroesophageal reflux symptoms and, in adults, with a development of Barrett's esophagus. Adults with Barrett's esophagus identified at baseline before bariatric operation are generally advised against VSG operations. The role of preoperative esophagogastroduodenoscopy (EGD) in adolescents preparing for bariatric surgery is not clearly defined. Objective: The goal of this study was to report the frequency of abnormalities identified on EGD performed at baseline in adolescents undergoing VSG for severe obesity. Setting: Free-standing academic children's hospital. United States. Methods: A retrospective chart review was conducted to describe findings of EGD performed just before VSG in a cohort of 40 adolescents and young adults (age range 14–25 yr) immediately before VSG. Review of findings from gross and histopathological evaluation of the esophagus, resected stomach, and duodenum was performed. Results: Five individuals reported preoperative symptoms of gastroesophageal reflux. Anatomic findings at EGD were normal in 98% of individuals. Histopathology of the esophagus, stomach, and duodenum was normal in 88%, 70%, and 95%, respectively. Abnormal findings of gastritis (18%), esophagitis (13%), and/or Helicobacter pylori (10%) infection were most common. Those with evidence of H. pylori in gastric resection specimens were treated appropriately with eradication therapy postoperatively. With the exception of 2 patients with incidentally detected esophageal mucosal eosinophilia, EGD findings did not lead to additional changes in medical or surgical management. There were no complications of the EGD procedure. Conclusions: Routine EGD at the time of VSG was safe but resulted in low yield of abnormal findings requiring a change in clinical management.
