Comparative Analysis of Laparoscopic Sleeve Gastrectomy with and Without Prior Endoscopic Intragastric Balloon Insertion: Examining Stomach Volumetry, Histopathologic Changes, Hormonal Levels, and Postoperative Outcomes.
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 2 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
backgroundThe effects of prior intragastric balloon (IGB) placement on stomach volumetry, surgical technique, and outcomes in laparoscopic sleeve gastrectomy (LSG) patients are unclear.
methodsThis prospective cohort study analyzed stomach histology, gastric volume, and hormonal markers in 90 LSG patients (45 with prior IGB, 45 without). We assessed stomach wall thickness, fibrosis, smooth muscle density, and ghrelin-positive cells, along with intraoperative parameters like stapler cartridge use and operative time. Postoperative outcomes, including weight loss and food tolerance (FT), were compared between groups at 6 months and 1 year.
resultsIn the 6th month and 1st year, the two groups had no differences in weight, BMI, and %TWL before and after the Inverse Propensity Score-Weighted adjustment. The IGB group had significantly increased muscular thickness, smooth muscle cell count, and fibrosis (p < 0.001) but similar mucosa thickness and inflammation. Preoperative stomach and resected specimen volumes were higher in the IGB group (p < 0.001). Both groups showed slight increases by 1 year, with no significant FT differences. Furthermore, no significant difference in postoperative complications was noted. Hormonal changes were observed, including lower leptin levels in the IGB group throughout.
conclusionWhile prior intragastric balloon (IGB) placement induces significant volumetry changes and hormone levels, it does not affect surgical outcomes-including postoperative complications, weight loss, resolution of associated medical problems, the duration of IGB placement, or the interval between IGB removal and LSG surgery-compared to those without IGB.
