Incidence and risk factors of symptomatic Petersen's hernias in bariatric and upper gastrointestinal surgery: a systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
purposeThe aim of this study was to investigate the actual incidence of symptomatic Petersen's hernias (PH) as well as identify risk factors for their occurrence.
methodsSearch was performed in Medline (via PubMed), Web of Science, and Cochrane library, using the keywords "Petersen Or Petersen's AND hernia" and "Internal hernia." Only studies of symptomatic PH were eligible. Fifty-three studies matched our criteria and were included. Risk of bias for each study was independently assessed using the checklist modification by Hoy et al. Analysis was performed using random-effects models, with subsequent subgroup analyses.
resultsA total of 81,701 patients were included. Mean time interval from index operation to PH diagnosis was 17.8 months. Total small bowel obstruction (SBO) events at Petersen's site were 737 (0.7%). SBO incidence was significantly higher in patients without defect closure (1.2% vs 0.3%, p < 0.01), but was not significantly affected by anastomosis fashion (retrocolic 0.7% vs antecolic 0.8%, p = 0.99). SBO incidence was also not significantly affected by the surgical approach (laparoscopic = 0.7% vs open = 0.1%, p = 0.18). However, retrocolic anastomosis was found to be associated with marginally, but not significantly, increased SBO rate in patients with Petersen's space closure, compared with the antecolic anastomosis (p = 0.09).
conclusionPH development may occur after any gastric operation with gastrojejunal anastomosis. Contrary to anastomosis fashion and surgical approach, defect closure was demonstrated to significantly reduce SBO incidence. Limitations of this study may include the high heterogeneity and the possible publication bias across the included studies.
