Banded Sleeve Gastrectomy vs Non-banded Sleeve Gastrectomy: a Systematic review and Meta-analysis.

ABSTRACT

Banded sleeve gastrectomy (BSG) was developed to restrict progressive dilation of the gastric sleeve, which remains a commonly implicated reason for weight regain following SG. The present study attempted to perform a systematic review and meta-analysis comparing the two procedures. Literature search was performed across PubMed and Google Scholar, using the keywords "Banded Sleeve Gastrectomy", "Sleeve gastrectomy", "Banded", "BSG" and "LSG". It yielded 4267 articles, six of which have been included in this review. Better weight loss outcomes at 3 and 5 years are noted following BSG, with a margin of 6.39% and 9.97% in %TWL at respective time points. No difference in impact on co-morbidities was noted. A revision rate of 7.1% was seen after BSG, with increased regurgitation as the most common indication.
