Mid-long-term Revisional Surgery After Sleeve Gastrectomy: a Systematic Review and Meta-analysis.

This study aimed to make a meta-analysis regarding mid-long-term outcomes (≥ 3-year follow-up) after sleeve gastrectomy (SG), focusing on incidence, reasons, and results of revisional surgery. PubMed, EMBASE, and CENTRAL were searched and 32 studies were included. The overall revision rate was 10.4%, but for patients with ≥ 10-year follow-up, the rate was 22.6%. European studies had a higher revision rate (14.4%) than other studies. The most common reason for revision was failure in weight loss, and the most frequent revisional procedure was gastric bypass. Revisional surgery was favorable for weight reduction and comorbidity resolution. In conclusion, revision rate is not rare after SG, especially when looking at long-term follow-up. Bariatric surgeons and patients need to fully understand and deal with the need for revision after SG.
