Routine upper endoscopy (esophagogastroduodenoscopy) before and after bariatric surgery is debated. This review supports systematic pre- and post-operative screening for bariatric patients to detect reflux and premalignant conditions.
Area of Science:
- Gastroenterology
- Bariatric Surgery
- Endoscopy
Background:
- The necessity of pre- and post-operative upper endoscopy (esophagogastroduodenoscopy, OGDF) in bariatric surgery patients lacks consensus.
- Concerns exist regarding gastroesophageal reflux disease and Barrett's esophagus after sleeve gastrectomy (SG), and premalignant lesions in excluded stomachs after Roux-en-Y gastric bypass (RYGB).
Discussion:
- The International Federation for the Surgery of Obesity and Metabolic Disorders recommends routine surveillance endoscopy after SG.
- This review synthesizes arguments favoring a systematic approach to preoperative and postoperative OGDF.
Key Insights:
- Systematic OGDF can identify risks like gastroesophageal reflux disease and Barrett's esophagus post-SG.
- Preoperative and postoperative OGDF can detect premalignant lesions in the excluded stomach after RYGB.
- Standardizing OGDF protocols may improve patient outcomes and safety in bariatric surgery.
Outlook:
- Further research is needed to establish definitive guidelines for OGDF in bariatric surgery.
- Implementing systematic OGDF could enhance the long-term management of bariatric patients.
- This approach may help in the early detection and management of potential complications.
