RESUMO
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]â =â -3.18; 95% CI [-5.45, -0.92], Pâ =â .006), %EWL after 1 year (MDâ =â 8.02; 95% CI [1.22, 14.81], Pâ =â .02), and %EWL after 3 years (MDâ =â 10.60; 95% CI [5.60, 15.69], Pâ <â .001) and similar results with LSG group in terms of operative time (MDâ =â 1.23; 95% CI [-4.71, 7.17], Pâ =â .69), food intolerance (ORâ =â 1.72; 95% CI [0.84, 3.49], Pâ =â .14), postoperative vomiting (ORâ =â 2.10; 95% CI [0.69, 6.35], Pâ =â .19), and De novo GERD (ORâ =â 0.65; 95% CI [0.34, 1.26], Pâ =â .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.
