Comparison of Naturally Banded vs Non-Banded Sleeve Gastrectomy: 2-Year Outcomes
Overview
This randomized controlled trial compared naturally banded sleeve gastrectomy (using Teres ligament or omental flap) with standard non-banded sleeve gastrectomy over two years. The study assessed weight loss, gastric volume, complications including GERD, and food tolerance, demonstrating the potential benefits of natural banding in reducing gastric pouch dilation and weight regain.
Background
Obesity is a global epidemic with severe obesity linked to multiple comorbidities and reduced life expectancy. Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery but is associated with long-term complications such as gastroesophageal reflux disease (GERD) and weight regain (WR). Sleeve dilation and increased gastric volume contribute to WR, prompting investigation into banding techniques to minimize these issues. Natural banding using the Teres ligament or omental flap may avoid complications seen with synthetic bands.

Key Findings
Natural banding with the Teres ligament or omental flap was feasible and safe in sleeve gastrectomy patients.
At 2 years, banded patients showed reduced gastric pouch dilation compared to non-banded patients.
Weight loss outcomes (%TWL and %EWL) were favorable in the natural banding group, potentially reducing weight regain.
Incidence of new-onset GERD was monitored, with natural banding aiming to minimize this complication.
Food tolerance scores were evaluated, indicating acceptable tolerance in both groups.
Operative time and complication rates were comparable between groups, with no significant increase in adverse events from natural banding.
Clinical Implications
Natural banding using autologous tissue flaps may offer a promising alternative to synthetic bands in sleeve gastrectomy by reducing gastric pouch dilation and weight regain without increasing complications. Surgeons should consider this technique for patients undergoing LSG to improve long-term outcomes while maintaining good food tolerance. Close postoperative monitoring for GERD remains essential.
Conclusion
Natural banded sleeve gastrectomy using the Teres ligament or omental flap is a safe and effective technique that may reduce gastric pouch dilation and weight regain over two years compared to non-banded LSG. This approach warrants further investigation as a strategy to optimize long-term bariatric surgery outcomes.
