Long-term Outcomes of Laparoscopic Sleeve Gastrectomy as a Revisional Procedure Following Adjustable Gastric Banding: Variations in Outcomes Based on Indication

BACKGROUND: Significant controversy exists regarding the indications and outcomes after laparoscopic adjustable gastric banding (LAGB) conversions to laparoscopic sleeve gastrectomy (LSG). AIM: To comprehensively determine the long-term outcomes of sleeve gastrectomy as a revisional procedure after LAGB across a range of measures and determine predictors of outcomes. METHODS: Six hundred revision LSG (RLSG) and 1200 controls (primary LSG (PLSG)) were included. Patient demographics, complications, follow-up, and patient-completed questionnaires were collected. RESULTS: RLSG vs controls; females 87% vs 78.8%, age 45 ± 19.4 vs 40.6 ± 10.6 years, p = 0.561; baseline weight 119.7 ± 26.2 vs 120.6 ± 26.5 kg p = 0.961)(.) Follow-up was 87% vs 89.3%. Weight loss in RLSG at 5 years, 22.9% vs 29.6% TBWL, p = 0.001, 10 years: 19.5% vs 27% TBWL, p = 0.001. RLSG had more complications (4.8 vs 2.0% RR 2.4, p = 0.001), re-admissions (4.3 vs 2.4% RR 1.8, p = 0.012), staple line leaks (2.5 vs 0.9%, p = 0.003). Eroded bands and baseline weight were independent predictors of complications after RLSG. Long-term re-operation rate was 7.3% for RLSG compared to 3.2% in controls. Severe oesophageal dysmotility predicted poor weight loss. RLSG reported lower quality of life scores (SF-12 physical component scores 75.9 vs 88%, p = 0.001), satisfaction (69 vs 93%, p = 0.001) and more frequent regurgitation (58% vs 42%, p = 0.034). CONCLUSION: RLSG provides long-term weight loss, although peri-operative complications are significantly elevated compared to PLSG. Longer-term re-operation rates are elevated compared to PLSG. Four variables predicted worse outcomes: eroded band, multiple prior bands, severe oesophageal dysmotility and elevated baseline weight.
