Clinical Scorecard: Long-Term Outcomes of Sleeve Gastrectomy in Adolescents: A Seven-Year Follow-Up Study

At a Glance

Key Highlights

• LSG in adolescents resulted in significant long-term weight loss and resolution of comorbidities over 7 years
• Low surgical complication rate (7.9%) including leak (1.59%), bleeding (1.59%), and wound infections (4.76%)
• Metabolic benefits included improved insulin sensitivity, normalized HbA1c, and remission of type 2 diabetes and hypertension

Guideline-Based Recommendations

Diagnosis

• Classify adolescent obesity as BMI ≥ 95th percentile for age and gender
• Assess obesity-related comorbidities including T2DM, hypertension, OSA, GERD, and dyslipidemia preoperatively
• Confirm failure of at least 6 months of medical weight management before surgical consideration

Management

• Perform laparoscopic sleeve gastrectomy with antral resection using a 36-French bougie
• Ensure preoperative multidisciplinary evaluation including patient and guardian counseling
• Monitor for and manage surgical complications such as staple line leaks, bleeding, and wound infections

Monitoring & Follow-up

• Regular postoperative follow-up assessing weight, BMI, %EWL, %TWL, %EBMIL, and gastric volume by 3D-CT volumetry at 1, 3, 5, and 7 years
• Evaluate resolution or remission of comorbidities using clinical parameters and laboratory markers (e.g., HbA1c for diabetes)
• Monitor psychological outcomes including quality of life and body image perception

Risks

• Potential surgical complications include staple line leak, bleeding, and wound infection
• Long-term psychological outcomes require further assessment due to limited data
• Loss to follow-up may impact outcome assessment

Patient & Prescribing Data

Adolescents aged 10-19 years with morbid obesity undergoing LSG after failed medical management

LSG provides durable weight loss and comorbidity resolution with low complication rates; requires multidisciplinary follow-up and monitoring

Clinical Best Practices

• Select patients carefully ensuring failure of non-surgical weight loss methods
• Use standardized surgical technique with antral resection and appropriate bougie size
• Implement comprehensive preoperative counseling involving patients and guardians
• Conduct long-term follow-up including objective measures of weight loss and comorbidity status
• Address psychological and quality of life outcomes alongside physical health
