Comparing Techniques for Mesenteric Defects Closure in Laparoscopic Gastric Bypass Surgery-a Register-Based Cohort Study.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundRoutine closure of mesenteric defects is generally considered standard part of laparoscopic gastric bypass surgery today. Controversy still exists regarding the optimal method for mesenteric defects closure. The objective was to compare different methods for mesenteric defects handling in laparoscopic gastric bypass surgery.
methodsPrimary laparoscopic gastric bypass procedures from 2010 until 2015 reported to the Scandinavian Obesity Surgery Registry (SOReg), where the mesenteric defects closure method was identifiable, were included. Main outcome measures were serious postoperative complication within 30 days after surgery, and reoperation for small bowel obstruction within 5 years after surgery. Quality-of-life before and after surgery, duration of surgery, and risk factors for complication were also analyzed. Information on operation for small bowel obstruction was based on data from the SOReg, the Swedish National Patient Register and reviews of hospital charts.
resultsIn all, 34,707 patients were included. Serious postoperative complication occurred in 174 (2.9%) patients with sutures, in 592 (3.1%, adjusted p = 0.079) with clips, and 278 (3.1%; adjusted p = 0.658) in the non-closure group. Reoperation for small bowel obstruction within 5 years after surgery was lower with sutures (cumulative incidence 6.9%) and clips (cumulative incidence 7.3%; adjusted HR 1.16, 95% CI 1.02-1.32, p = 0.026), compared to non-closure (cumulative incidence 11.2%; adjusted HR 1.63, 95% CI 1.44-1.84, p < 0.0001).
conclusionClosure of the mesenteric defects using either non-absorbable metal clips or non-absorbable running sutures is a safe and effective measure to reduce the risk for small bowel obstruction after laparoscopic gastric bypass surgery. Sutures appear slightly more effective and should remain gold standard for mesenteric defects closure.
