Late Complications of Bleeding in the First 24 H After Laparoscopic Sleeve Gastrectomy: A Retrospective Cohort Study.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 objective of this study was to assess the long-term (≥ 12 months) clinical outcomes of early postoperative bleeding (within 24 h) following laparoscopic sleeve gastrectomy (LSG). The focus was on late complications such as persistent vomiting, constipation, malnutrition, gastroesophageal reflux disease (GERD), gastric stenosis, muscle wasting, and sarcopenia.
methodsA total of 463 patients who underwent LSG between 2019 and 2024 were retrospectively analyzed.Among them, 27 patients developed early postoperative bleeding, confirmed by clinical and radiologic evidence, and treated according to the Clavien-Dindo classification. All patients had at least 12 months of follow-up, during which complications were evaluated using standardized diagnostic definitions. Statistical comparisons were made between bleeding and non-bleeding groups.
resultsPatients with early bleeding had significantly higher rates of persistent vomiting (33.3% vs. 6.2%), constipation (40.7% vs. 14.2%), malnutrition (29.6% vs. 6.3%), and GERD (29.6% vs. 6.2%), gastric stenosis (14.8% vs. 1.3%), and sarcopenia (mean muscle wasting: 23.7% vs. 14.8%) (p < 0.001). Bleeding increased the risk of severe sarcopenia (> 20% muscle wasting) by 6.2-fold.
conclusionBleeding within the first 24 h after LSG has a negative impact on long-term clinical outcomes, and regular follow-up and early intervention, nutritional support, and multidisciplinary follow-up strategies are critical for managing this patient group.
