Banded versus non-banded sleeve gastrectomy: A systematic review and meta-analysis

Abstract

Background: Laparoscopic banded sleeve gastrectomy (LBSG) has been compared to laparoscopic sleeve gastrectomy (LSG) in terms of anthropometric results and postoperative complications, which are controversial. This systematic review and meta-analysis aimed to compare the safety and efficacy of LBSG and LSG. Methods: We performed a systematic review with meta-analysis according to preferred reporting items for systematic review and meta-analysis 2020 and assessing the methodological quality of systematic review 2 guidelines. We included studies that systematically searched electronic databases and compared LBSG with LSG conducted until August 10, 2021. Results: The literature search yielded 8 comparative studies. Seven hundred forty-three patients were included: 352 in the LBSG group and 391 in the LSG group. LBSG group allowed greater anthropometric parameters (body mass index [BMI] after 1 year (mean difference [MD] = −3.18; 95% CI [−5.45, −0.92], P = .006), %EWL after 1 year (MD = 8.02; 95% CI [1.22, 14.81], P = .02), and %EWL after 3 years (MD = 10.60; 95% CI [5.60, 15.69], P < .001) and similar results with LSG group in terms of operative time (MD = 1.23; 95% CI [−4.71, 7.17], P = .69), food intolerance (OR = 1.72; 95% CI [0.84, 3.49], P = .14), postoperative vomiting (OR = 2.10; 95% CI [0.69, 6.35], P = .19), and De novo GERD (OR = 0.65; 95% CI [0.34, 1.26], P = .2). Nevertheless, major postoperative complications did not differ between the 2 groups. Conclusions: This systematic review and meta-analysis comparing LBSG and LSG concluded that banding sleeve gastrectomy (SG) may ensure a lower BMI and %EWL after 1 year of follow-up, and a significant reduction in %EWL after 3 years of follow-up. There is no evidence to support LBSG in vomiting, de novo GERD, food intolerance, or operative time.

Banded Versus Non-banded Sleeve Gastrectomy: A Systematic Review and Meta-Analysis

“…Additionally, the study noted a significant reduction in %EWL after both one year and three years of followup in the banded group. However, the analysis found no substantial evidence supporting the superiority of LBSG over LSG in terms of mitigating vomiting, de novo gastroesophageal reflux disease (GERD), food intolerance, or reducing operative time [11]. This aligned with our findings regarding BMI, %EWL, reflux, and operative time.…”
