Key result
Significant variations in study design and critical risk of bias across 12 trials prevented meaningful comparison of weight-related outcomes after revisional bariatric surgery for sleeve gastrectomy non-response.
Why the study?
Weight non-response after sleeve gastrectomy is an emerging issue, prompting a systematic review to compare revisional procedures for weight-related outcomes.
Does revisional bariatric surgery improve weight loss in adult patients with non-response after sleeve gastrectomy?

Does revisional bariatric surgery improve weight loss in adult patients with non-response after sleeve gastrectomy?
Current literature lacks high-quality evidence to guide the choice of revisional bariatric surgery for weight non-response after sleeve gastrectomy, highlighting the need for standardized prospective studies.
Critical bias precludes evidence-based revisional choices after sleeve gastrectomy; leaves open the need for standardized prospective trials.
Weight non-response after sleeve gastrectomy is an emerging issue. This systematic review compared revisional procedures for weight-related outcomes. We searched several databases for relevant articles and included adult patients with revisional bariatric procedures after primary sleeve gastrectomy. Twelve trials with 1046 patients were included, covering five revisional procedures. There were no randomised controlled trials, and 10 studies had a critical risk of bias. Significant variations in inclusion criteria, therapy benchmarks, follow-up schemes, and outcome measurements were observed, preventing meaningful comparison of results. Evidence-based treatment strategies for weight non-response after sleeve gastrectomy cannot be deduced from the current literature. Prospective studies with well-defined indications, standardised techniques, and strict adherence to outcome measurements are needed.

Axer et al. (2023) conducted a systematic review in Weight non-response after sleeve gastrectomy (n=1,046). Revisional bariatric surgery vs. Other revisional bariatric procedures was evaluated on Weight change after revisional surgery (BMI, %TWL, %EWL, or %EBMI loss). Significant variations in study design and critical risk of bias across 12 trials prevented meaningful comparison of weight-related outcomes after revisional bariatric surgery for sleeve gastrectomy non-response.
