Incidence and Risk Factors of In-Hospital Gastrointestinal-Related Complications Following Bariatric Surgery: A Retrospective Nationwide Inpatient Sample Database Study.
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 5 papers, 1 of them a synthesis that pooled it.
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
backgroundObesity is associated with numerous serious physiological and psychological health problems. Bariatric surgery (BS) remains the most effective treatment for obesity, but early postoperative gastrointestinal complications may require additional surgical intervention. The objective of this study was to analyze gastrointestinal-related complications (GRCs) and their risk factors following BS, including sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), using a nationwide database.
methodsAn analysis of the Nationwide Inpatient Sample data from 2010 to 2019 was conducted to compare patients following BS with versus without postoperative GRCs. Variables included demographics, hospital characteristics, length of stay, costs, comorbidities, and complications. Risk factors were identified through stepwise multivariate logistic regression.
resultsAmong 323,066 BS patients, 12,248 (3.79%) developed GRCs, with a decreasing trend observed over the study period. Common complications included gastrointestinal bleeding (1.37%), bowel obstruction (1.84%), and anastomotic issues (0.99%). Significant risk factors included advanced age, anemia (deficiency and chronic blood loss), cardiovascular conditions (heart failure, valve disease, peripheral vascular disorders), coagulation abnormalities, rheumatoid arthritis or collagen vascular diseases, drug abuse, electrolyte imbalances, neurological conditions, renal failure, non-bleeding peptic ulcer disease, and weight loss. Interestingly, liver disease emerged as a risk factor for GRCs after SG while acting as a protective factor for GRCs after RYGB.
conclusionUnderstanding the risk factors for GRCs after BS would allow for improved patient management and clinical outcomes.
