Clinical Scorecard: Roux-en-Y Gastric Bypass for Managing Barrett’s Esophagus Following Sleeve Gastrectomy

At a Glance

Key Highlights

• Sleeve gastrectomy is the most common bariatric procedure but may lead to reflux and Barrett’s Esophagus in the long term.
• Conversion from SG to RYGB is an effective surgical option to treat reflux and potentially manage BE.
• Comprehensive evaluation including gastroscopy, manometry, and 24 h pH-metry is essential for diagnosis and follow-up.

Guideline-Based Recommendations

Diagnosis

• Perform gastroscopy with Seattle protocol biopsies to diagnose BE, requiring intestinal metaplasia and goblet cells.
• Use manometry and 24 h pH-metry with impedance to assess reflux severity and esophageal function.
• Evaluate patients with symptomatic reflux after SG for esophagitis and BE.

Management

• Initial conservative treatment with lifestyle modifications and proton-pump inhibitors (PPI) for reflux symptoms.
• Consider conversion from SG to RYGB in patients with persistent reflux and BE.
• Treat hiatal hernias intraoperatively during RYGB with hiatoplasty as needed.

Monitoring & Follow-up

• Conduct gastroscopies before SG, after SG, and after conversion to RYGB to monitor esophageal mucosa.
• Use symptom questionnaires (GIQLI and BAROS scores) to assess patient-reported outcomes.
• Follow-up post-RYGB for at least 6 months to evaluate reflux control and BE status.

Risks

• Potential persistence or recurrence of reflux symptoms even after RYGB.
• Risk of esophagitis and progression of BE if reflux is not adequately controlled post-SG.
• Surgical risks associated with conversion procedures and hiatoplasty.

Patient & Prescribing Data

Morbidly obese female patients post-SG with reflux and Barrett’s Esophagus

Patients initially treated conservatively with PPIs and lifestyle changes but required surgical conversion due to persistent reflux and BE.

Clinical Best Practices

• Use a multidisciplinary approach including gastroenterologists and bariatric surgeons for managing BE after SG.
• Apply the Seattle protocol during endoscopy for accurate diagnosis and surveillance of BE.
• Perform hiatoplasty during RYGB if hiatal hernia is present to optimize reflux control.
• Close internal hernia sites during RYGB to reduce postoperative complications.
• Ensure informed consent and ethical approval for all interventions and studies.
