1 · What the graph read from 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.

2 · The registry

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

introductionDespite its clinical significance and the fact that mechanical adhesive small bowel obstruction (SBO) is a common surgical emergency, data on the prevalence, types and risk factors of morbidity remain limited. This study aims to assess the frequency and kind of complications and identify patient- and surgery-related risk factors, with particular attention to the impact of surgical timing.

methodsWe conducted a retrospective analysis of patients who underwent surgery for mechanical adhesive SBO at the University Hospital Erlangen over a five-year period (2018–2022). Postoperative complications and their outcomes were assessed. Univariate and multivariate logistic regression analyses were conducted to identify independent risk factors associated with postoperative morbidity.

resultsPostoperative in-hospital morbidity occurred in 22.2% of patients, the majority of which were surgery-related (71.2%). The most frequent complications were postoperative paralytic ileus (6.0%), wound healing disorders (5.1%) and cardiopulmonary complications (5.1%). The in-hospital mortality rate was 2.1%. Postoperative morbidity was managed conservatively in 75.0% of cases and required reoperation in 25.0%. In 89.4% of affected patients, morbidity was associated with prolonged hospitalization. Multivariate analysis identified BMI > 25 kg/m² (OR 2.9; 95% CI, 1.4–6.0; p = 0.007), ASA class III–IV (OR 3.0; 95% CI, 1.4–6.5; p = 0.007) and surgery duration > 110 minutes (OR 4.0; 95% CI, 1.9–8.7; p < 0.001) as independent predictors of morbidity. In contrast, surgical timing – specifically nighttime procedures (p = 0.200) and weekend surgery (p = 0.572) - was not significantly associated with increased risk.

conclusionIn surgically treated patients with adhesive small bowel obstruction, postoperative morbidity was independently associated with elevated BMI, ASA class III–IV, and prolonged operative duration. In contrast, nighttime and weekend surgery were not significantly associated with postoperative morbidity in this cohort. These findings underscore the importance of risk-adapted perioperative optimization and close interdisciplinary management, particularly in high-risk patients.
