Trends in the Evaluation and Treatment of Patients Presenting With Sigmoid Volvulus Over the Past 15 Years.
Article in Cureus, 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
backgroundFew studies have assessed changes over time in the evaluation and treatment of patients presenting with acute sigmoid volvulus. We sought to evaluate trends in sigmoid volvulus care at a single center between 2010 and 2024. We hypothesized that there would be increasing rates in the use of computed tomography (CT) scans, lactate levels, laparoscopic surgery, and same-admission surgery.
methodsA single-center, retrospective study was performed for all adult admissions for acute sigmoid volvulus over 15 years (2010-2024). Each admission was assessed individually for demographic, clinical, laboratory, radiographic, endoscopic, and surgical data. As each admission was assessed separately and was the unit of analysis, some patients could contribute multiple episodes to the study. Outcomes were compared between three five-year periods (2010-2014, 2015-2019, 2020-2024).
resultsOne hundred and eighty-four episodes of sigmoid volvulus from 103 unique patients were included (median age 77.0 [IQR 66.2-83.0], 76.6% male). CT scan use increased from 17.6% to 25.7% to 47.6% (p=0.001 groups 1 vs 3; p=0.009 groups 2 vs 3; p trend <0.001). While the rate in which lactate was checked did not significantly change over time (p trend 0.634), the rate in which C-reactive protein (CRP) was assessed increased from 29.4% to 75.7% to 92.1% (p<0.001 for groups 1 vs 2; p<0.001 for groups 1 vs 3; p=0.011 for groups 2 vs 3; p trend <0.001). The rates of same-admission surgery (13.7% to 21.7% to 23.8% of all cases; p trend=0.193) and laparoscopic surgery (0% to 13.3% to 20.0% of all same-admission surgeries; p trend=0.219) trended upwards but were not statistically significant. Patient outcomes, including mortality (p trend=0.747), did not significantly change during the study period.
conclusionsCT scans and CRP are increasingly being used, while surgical trends are progressing more slowly in the management of sigmoid volvulus patients, although these changes have not been associated with detectable changes in outcomes. Limited power and confounding may obscure small effects and have limited our findings. Larger, multi-center studies may help to better elucidate these trends.
