Risk Prediction of Postoperative Complications in Lower Gastrointestinal Perforation Based on Preoperative Serum Cholinesterase Levels.
Article in Journal of the anus, rectum and colon, 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
Objectives: Cholinesterase is recognized as a marker for nutritional status and associated with inflammatory conditions. The present study aims to evaluate the association between cholinesterase and postoperative complications in patients with lower gastrointestinal perforation. Methods: The study included 71 patients who had undergone emergency surgery for lower gastrointestinal perforation. We retrospectively investigated the relationship between preoperative serum cholinesterase levels and postoperative complications. Complications were defined as Clavien-Dindo (C-D) grade II or higher, with severe complications classified as C-D grade III-V. We performed univariate and multivariate analyses to evaluate independent risk factors for postoperative complications. Results: Among of all, 43 patients (61%) developed postoperative all complications (C-D ≥ II), and 17 patients (24%) developed severe complications (C-D ≥ III-V). In multivariate analysis, cholinesterase (p=0.006), C-reactive protein (p=0.028), and blood loss (p=0.028) were independent risk factors for postoperative all complications (C-D ≥ II). Also, cholinesterase (p=0.006) was an independent risk factors for postoperative severe complication (C-D ≥ III- V). Patients in the cholinesterase-low group had significantly lower preoperative hemoglobin (p=0.001), albumin (p<0.001), and prognostic nutritional index (p<0.001), as well as higher C-reactive protein (p=0.010), neutrophil-lymphocyte ratio (p=0.038), proportion of wound infection (30% vs. 4.8%, p=0.026) and abdominal abscess (30% vs. 0.0%, p=0.003) compared to those in the cholinesterase-high group. Conclusions: Preoperative serum cholinesterase levels may be associated with postoperative severe course in patients with lower gastrointestinal perforation. This association underscores the potential role of cholinesterase as an indicator of nutritional and inflammatory status.
