Clinical Scorecard: Long-Term Effects of Laparoscopic Sleeve Gastrectomy on Weight Reduction in Obese Patients: Findings from a 5-Year and 11-Year Follow-Up Analysis

At a Glance

Key Highlights

• LSG is the most frequently performed bariatric surgery since 2014 due to its safety, efficacy, and technical simplicity
• Long-term follow-up (5 to 11 years) is essential to reliably assess sustained weight loss and control of obesity-related complications
• Patients with severe GERD or large hiatus hernia are excluded from LSG candidacy to optimize outcomes

Guideline-Based Recommendations

Diagnosis

• Assess obesity severity and related metabolic disorders through clinical evaluation and laboratory investigations
• Screen for GERD symptoms using validated questionnaires and confirm with upper gastrointestinal endoscopy
• Exclude patients with severe GERD (heartburn score ≥ 2, regurgitation score 3) or esophagitis higher than grade B (LA classification) and those with large hiatus hernia (>4 cm)

Management

• Perform LSG under general anesthesia with standardized technique using a 36 Fr bougie for sleeve calibration
• Provide routine postoperative care including early mobilization, dietary guidance, and supplementation
• Schedule follow-up visits at 3, 6, and 12 months postoperatively and long-term follow-up at 5 and 11 years
• Repair small hiatus hernia intraoperatively if identified, avoiding mesh use

Monitoring & Follow-up

• Monitor weight loss using excess body weight loss percentage (EBWL%) and total weight loss percentage (TWL%) at short-term and long-term intervals
• Evaluate resolution or persistence of obesity-related complications per American Society for Metabolic and Bariatric Surgery standardized outcomes
• Assess GERD symptoms and PPI use beyond routine postoperative period to identify new or persistent reflux

Risks

• Potential development or worsening of GERD post-LSG in susceptible patients
• Exclusion of patients with severe GERD or large hiatus hernia to minimize postoperative reflux complications
• Need for long-term follow-up to identify late complications or weight regain

Patient & Prescribing Data

892 patients aged 18-60 years undergoing LSG over an 11-year period

LSG provides sustained weight loss and improvement in obesity-related metabolic disorders with careful patient selection and long-term follow-up

Clinical Best Practices

• Conduct thorough preoperative multidisciplinary assessment including GERD symptom scoring and endoscopy
• Exclude patients with severe GERD or large hiatus hernia from LSG candidacy
• Use standardized surgical technique with bougie calibration to ensure consistent sleeve size
• Implement structured postoperative care with scheduled follow-ups and patient education on diet and supplementation
• Perform long-term follow-up beyond 5 years to assess durability of weight loss and metabolic improvements
