Mesenteric pneumatosis on CT: a predictor of benign pneumatosis intestinalis.

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
purposeTo determine whether specific CT findings, particularly mesenteric pneumatosis, can help differentiate benign from life-threatening pneumatosis intestinalis (PI).
methodsThis retrospective study included adult patients with PI identified on abdominal CT between January 2013 and December 2022. Clinical data, including referral source and laboratory test results, were collected. Two radiologists analyzed CT features, including PI location and extent, circumferential gas, mesenteric pneumatosis, portomesenteric venous gas, decreased mural enhancement, bowel dilatation, mesenteric fat stranding, free peritoneal air, and free peritoneal fluid. Patients were classified as having benign or life-threatening PI based on clinical outcomes. Statistical analyses were performed to identify predictors of life-threatening PI.
resultsA total of 215 patients were included, with 72 (33%) classified as benign PI and 143 (67%) as life-threatening PI. Multivariate analysis identified portomesenteric venous gas (p < 0.001, OR = 10.39), decreased mural enhancement (p = 0.046, OR = 6.47), and intensive care unit referral (p = 0.011, OR = 10.15) as independent predictors of life-threatening PI. Mesenteric pneumatosis (p = 0.025, OR = 0.14) was an independent predictor of benign PI. Bowel ischemia was the most common etiology of PI, accounting for 61.9% of cases.
conclusionMesenteric pneumatosis is a key predictor of benign PI, while referral from intensive care units, portomesenteric venous gas, and decreased mural enhancement indicate life-threatening PI. These findings may aid in identifying patients requiring urgent intervention while helping to avoid unnecessary surgery in benign cases.
