Long-Term Safety and Efficacy Profile of Bariatric Surgery in Patients Classified with ASA IV Status.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMetabolic and bariatric surgery (MBS) is a safe and effective treatment option to reduce weight and manage obesity-related medical conditions in patients with obesity. However, due to limited data, there is uncertainty regarding the short-, mid-, and long-term safety and efficacy profile of MBS in patients with a preoperative ASA IV status.
methodsA single-center retrospective cohort study was performed on patients with ASA IV status who underwent sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), or biliopancreatic diversion with duodenal switch (BPD-DS) between 2008 and 2020. Data collected included operative details; postoperative complications at 30 days, 90 days, and beyond 90 days; BMI changes; and resolution of obesity-related comorbidities at 0, 6, 12, 24, 48, and 60 months postoperatively.
resultsAmong 131 ASA class IV patients, 43 patients underwent SG (32.8%), 66 patients underwent RYGB (50.4%), and 22 patients underwent BPD-DS (16.8%). The greatest %TWL occurred in the BPD-DS cohort (39.5%) at 24 months post-op followed by the RYGB (32.5%) and SG (20.7%) cohorts (p < 0.001). The overall major 30-day complication rate was 8.4% (n = 11/131), while the overall major 90-day complication rate within the cohort was 6.9% (n = 9/131). The overall major late (> 90 days) complication rate was found to be 14.5% (n = 19/131).
conclusionsOur study demonstrated that MBS is relatively safe and effective in ASA IV patients in the short-, mid-, and long-term. Accordingly, careful procedure selection is required in this patient population. Further long-term studies are needed to support our findings.
