1 · What the graph read from 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.

2 · The registry

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

backgroundMinimally invasive bariatric surgeries provide effective weight loss with fewer complications. However, postoperative bleeding remains a significant concern due to its potential for serious morbidity and mortality. This study aimed to identify factors predicting postoperative bleeding following laparoscopic and robotic sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).

methodsWe analyzed patients who underwent SG and RYGB using the MBSAQIP database from 2015 to 2021. Four multivariate logistic regression analyses were conducted to investigate the relationship between postoperative bleeding and 24 independent factors for laparoscopic SG (lapSG), robotic SG (rSG), laparoscopic RYGB (lapRYGB), and robotic RYGB (rRYGB).

resultsWe analyzed 659,294 lapSG, 53,548 rSG, 267,171 lapRYGB, and 22,492 rRYGB patients. In lapSG, the most significant factors included anticoagulation (OR 3.76; 95% CI 3.13-4.51), renal insufficiency (OR 2.06; 95% CI 1.37-3.09), history of DVT (OR 1.87; 95% CI 1.23-2.85), history of PE (OR 1.69; 95% CI 1.04-2.76, and BMI ≤ 40 (OR 1.22; 95% CI 1.09-1.38). In the rSG group, anticoagulation (OR 4.95; 95% CI 2.83-8.66), COPD (OR 2.80; 95% CI 1.29-6.05), and hyperlipidemia (OR 1.90; 95% CI 1.29-6.05) were significant factors. In lapRYGB, the most significant factors included anticoagulation (OR 3.68; 95% CI 3.11-4.35), renal insufficiency (OR 1.60; 95% CI 1.04-2.44), history of DVT (OR 1.70; 95% CI 1.09-2.07), cardiac stent (OR 1.51; 95% CI 1.09-2.07), and BMI ≤ 40 (OR 1.16; 95% CI 1.03-1.29). For rRYGB, anticoagulation (OR 4.69; 95% CI 2.86-7.70), history of PE (OR 4.28; 95% CI 1.53-12.00), and cardiac stent (OR 2.15; 95% CI 0.06-4.34) were significant.

conclusionPreoperative anticoagulation, renal insufficiency, history of DVT and PE, a cardiac stent, and BMI ≤ 40 are associated with an increased risk of postoperative bleeding. The predictive factors were consistent across laparoscopic and robotic approaches in SG and RYGB procedures.
