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.
