Long-Term Effects of Laparoscopic Sleeve Gastrectomy on Weight Reduction

Overview

This retrospective study evaluated the long-term efficacy of laparoscopic sleeve gastrectomy (LSG) in 892 obese patients over a follow-up period extending up to 11 years. The findings demonstrate sustained weight loss and improvement in obesity-related complications, confirming LSG as an effective long-term treatment for severe obesity.

Background

Obesity is a global epidemic associated with numerous health complications. Bariatric surgery, particularly laparoscopic sleeve gastrectomy, has become the most commonly performed procedure due to its safety and efficacy. While short-term benefits of LSG are well documented, long-term outcomes beyond 10 years remain scarce. This study addresses this gap by analyzing weight loss and complication resolution over extended follow-up periods.

Data Highlights

A total of 892 patients underwent LSG between 2011 and 2022, with ages ranging from 18 to 60 years (mean 35.98 ± 10.25). Follow-up assessments were conducted at 3, 6, and 12 months postoperatively, and at 5 and 11 years for long-term evaluation. Weight loss was measured using excess body weight loss percentage (EBWL%) and total weight loss percentage (TWL%). Obesity-related complications and GERD symptoms were also monitored.

Key Findings

• LSG resulted in significant weight loss sustained up to 11 years postoperatively.
• Early postoperative follow-ups at 3, 6, and 12 months showed progressive weight reduction.
• Long-term follow-up at 5 and 11 years confirmed maintenance of weight loss and improvement in obesity-related metabolic disorders.
• Patients with severe GERD or large hiatus hernia were excluded to optimize outcomes.
• GERD symptoms were assessed pre- and postoperatively, with careful monitoring and management following surgery.

Clinical Implications

LSG is a safe and effective long-term treatment option for patients with severe obesity, providing sustained weight loss and improvement in obesity-related complications. Careful patient selection, particularly excluding those with severe GERD or large hiatus hernia, is critical to optimize outcomes. Regular follow-up is essential to monitor weight and manage potential complications.

Conclusion

Laparoscopic sleeve gastrectomy offers durable weight loss and metabolic benefits over a long-term period of up to 11 years, supporting its role as a primary bariatric procedure for severe obesity. Continued monitoring and patient selection remain key to maximizing clinical success.
