Clinical Scorecard: Comparison of Naturally Banded and Non-Banded Sleeve Gastrectomy: A Controlled Clinical Trial with Two-Year Follow-Up

At a Glance

Key Highlights

• Banded LSG using a natural flap (Teres ligament or omental flap) aims to prevent gastric pouch dilation and reduce weight regain.
• Non-banded LSG is associated with higher rates of weight regain and new-onset GERD symptoms over time.
• Natural banding avoids synthetic ring complications and shows promising 2-year follow-up results.

Guideline-Based Recommendations

Diagnosis

• Preoperative evaluation including medical history, laboratory tests, and endoscopy for patients with moderate to severe GERD symptoms.
• Use of gastric volumetry by multi-detector computed tomography (MDCT) at 2-year follow-up to assess sleeve size.

Management

• Perform laparoscopic sleeve gastrectomy with natural banding using Teres ligament or omental flap to minimize pouch dilation and weight regain.
• Administer low-molecular-weight heparin (LMWH) 12 hours before surgery to reduce thrombotic risk.
• Close postoperative monitoring for GERD symptoms and weight loss outcomes.

Monitoring & Follow-up

• Evaluate weight loss outcomes at 2 years using percentage total weight loss (%TWL) and percentage excess weight loss (%EWL).
• Assess food tolerance using validated questionnaires at follow-up.
• Monitor for complications according to Clavien–Dindo classification, especially new-onset GERD.

Risks

• Potential for GERD development or worsening post-LSG, especially with radical antrectomy or sleeve dilation.
• Risk of gallstone formation due to rapid weight loss; preventive strategies remain controversial.
• Complications related to synthetic bands (not applicable to natural banding) include slipping, stenosis, and erosion.

Patient & Prescribing Data

Adults undergoing LSG for severe obesity without prior weight-loss surgery or preoperative GERD symptoms.

Natural banding with Teres ligament or omental flap may reduce sleeve dilation and weight regain without synthetic band complications over 2 years.

Clinical Best Practices

• Use natural anatomical flaps (Teres ligament or omental flap) for banding to avoid synthetic ring complications.
• Implement rigorous preoperative screening including GERD assessment and laboratory testing.
• Ensure randomized allocation and blinding in clinical trials to reduce bias.
• Conduct long-term follow-up with objective measures of gastric volume and standardized weight loss metrics.
• Provide patient education on risks, benefits, and postoperative expectations prior to surgery.
