Visceral fat-to-muscle ratio is associated with inflammatory ileus after excision of intestinal fistula with severe abdominal adhesions.
Article in BMC surgery, 2025. 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
backgroundPostoperative inflammatory ileus (PII) is characterised by long-term re-obstruction, following temporary defecation. An intestinal fistula excision (IFE) with severe abdominal adhesions could increase the risk of PII in patients with sarcopenia. On the other hand, the postoperative outcomes are negatively impacted owing to chronic preoperative inflammation, as measured by the visceral fat area (VFA) and the total abdominal muscle area index (TAMAI) ratio. This study aims to evaluate the predictability of VFA/TAMAI for postoperative PII after IFE.
methodsFour tertiary centres participated in this retrospective cohort study. Patients with sarcopenia who underwent IFE between January 2018 and October 2022 were enrolled. VFA/TAMAI was evaluated as a risk factor for PII.
resultsWe included 177 eligible patients (102 [57.6%] males) with a median age of 51 years (interquartile range [IQR]: 38-61 years) in this study. PII occurred in 16.9% of patients (n = 30), with an interval of four days (IQR: 3-5 days) between IFE and temporary defecation. The duration of the re-obstruction after temporary defecation was 23 days (IQR: 21-30 days), following temporary defecation that lasted for one days (IQR: 1-2 days). The adjusted logistic regression revealed that VFA/TAMAI was associated with PII (odds ratio = 1.51, 95% confidence interval: 1.02-2.19; p = 0.03).
conclusionVFA/TAMAI was associated with inflammatory ileus after IFE with severe abdominal adhesions in patients with sarcopenia.
