摘要

The intragastric balloon (IGB) acts as a restrictive procedure with acceptable short-term weight loss outcomes and a low incidence of major complications. This systematic review and meta-analysis aimed to assess whether preoperative insertion of an IGB can reduce perioperative complications and improve weight loss outcomes following metabolic bariatric surgery (MBS). PubMed, Embase, Scopus, and Web of Science databases were searched using relevant keywords to include studies on IGB as a bridge before MBS. The main outcome of this study was to compare the weight loss results and complications after MBS between the IGB group and the control group. For the meta-analysis of variables with severe and non-severe heterogeneity, random-effects and fixed-effects meta-analyses were used, respectively. Eleven articles were included. The IGB and control groups included 318 and 501 patients, respectively. The pooled random-effects analysis of six studies showed that preoperative IGB insertion resulted in a body mass index (BMI) loss of 7.45 kg/m2 over a mean follow-up of 6.14 months. The major complication rate for IGB was 5%. The mean BMI change after MBS between the IGB and control groups was not significantly different after 15.06 months (mean difference − 4.08, p = 0.07). Additionally, a fixed-effects analysis of ten studies found no significant difference in post-MBS complication rates between the IGB and control groups (OR 0.66, p = 0.12). Even though using IGB as a bridging approach to subsequent MBS can result in significant reductions in preoperative BMI, this weight loss does not appear to positively impact the overall outcomes of MBS in patients in the long term.
