Clinical Scorecard: Comparative Outcomes of Roux-En-Y Gastric Bypass and Fundoplication in Obese Patients with Refractory GERD: A Systematic Review and Meta-Analysis

At a Glance

Key Highlights

• RYGB is considered the gold-standard surgical technique for severe obesity (BMI > 40) with superior reflux control by diverting gastric acid away from the esophagus.
• Fundoplication shows higher reflux recurrence rates in obese patients but similar perioperative complications and recovery compared to RYGB.
• Evidence is conflicting for moderate obesity (BMI 30–40) regarding whether fundoplication alone or RYGB provides better long-term reflux control.

Guideline-Based Recommendations

Diagnosis

• Use objective measures such as postoperative DeMeester score (<14.1) and validated symptom questionnaires (GERD-HRQL, RSI, GERSS) to assess GERD resolution.

Management

• Consider RYGB as the preferred surgical option for patients with severe obesity and refractory GERD.
• Fundoplication remains an option but may have higher reflux recurrence in obese patients.
• In cases of failed fundoplication, RYGB is recommended over redo-fundoplication for definitive reflux control.
• When RYGB is contraindicated, novel procedures like Nissen-sleeve may be considered.

Monitoring & Follow-up

• Monitor for postoperative complications including intraoperative events, dysphagia, and need for reoperation.
• Assess weight loss outcomes using percentage of total weight loss (%TWL).

Risks

• Higher reflux recurrence rates after fundoplication in obese patients.
• Potential perioperative complications comparable between RYGB and fundoplication.
• Consideration of patient-specific factors such as presence of large paraesophageal hernias or Barrett’s esophagus.

Patient & Prescribing Data

Adults with obesity (BMI > 30 kg/m²) and refractory GERD undergoing primary surgical intervention

RYGB offers superior reflux control especially in severe obesity, with comparable morbidity to fundoplication; fundoplication may be less effective long-term in obese patients.

Clinical Best Practices

• Perform comprehensive preoperative evaluation including objective reflux testing and symptom assessment.
• Select surgical intervention based on obesity severity, reflux severity, and patient comorbidities.
• Consider RYGB preferentially in patients with BMI > 40 or failed prior fundoplication.
• Use validated outcome measures to monitor postoperative reflux resolution and weight loss.
• Tailor surgical approach in patients with complex presentations such as large hernias or Barrett’s esophagus.
