Mesenteric Defects Closure Using N-Hexyl-Cyanoacrylate Surgical Glue During Roux-en-Y Gastric Bypass: A Single-Center Observational Study.
Article in Cureus, 2026. 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
Background and objective Small bowel obstruction (SBO) with internal hernia (IH) is a life-threatening complication following minimally invasive Roux-en-Y gastric bypass (mRYGB). IH occurs frequently within the first two to three years after surgery, with an incidence ranging from 0.5% to 9%. Mesenteric defect closure (MDC) is consistently recommended. However, the technique remains controversial. Suturing, which is the most commonly used technique, can be risky due to mesenteric hemorrhage and hematoma. Glue application for MDC may offer an alternative. The objective of this observational study was to report the incidence of IH after the routine use of surgical glue for MDC during mRYGB. Methods We conducted an observational study to investigate this topic. From January 2020 to January 2022, a total of 170 consecutive patients who underwent mRYGB with surgical glue used for MDC were prospectively followed, and their data were analyzed. Results The mean age of the cohort was 43 ± 10 years. The mean BMI was 43 ± 3 kg/m². Laparoscopic RYGB was performed in 79% of patients, while robotic mRYGB accounted for 20%. The mean excess weight loss was 14 ± 16%. The median glue application time was eight minutes (range: 6-10 minutes), including application and polymerization time. The mean follow-up duration was 42 months (range: 17-71 months); 80% of patients had more than 24 months of follow-up. No clinically significant IH was observed during the follow-up period, while one patient underwent surgery for acute SBO without IH. Conclusions The preliminary results of MDC using surgical glue during mRYGB are promising in terms of feasibility and tolerance. The absence of IH observed during this follow-up is noteworthy but should be interpreted with caution due to the presence of potential biases. Further multi-institutional prospective studies are needed to gain deeper insights into the topic.
