Risk Factors for Anastomotic Leaks in Simultaneous Resection of Primary Colon Cancer with Synchronous Liver Metastasis: A NSQIP Study.
Article in Annals of surgical oncology, 2026. 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
introductionAnastomotic leaks (AL) are a devastating complication of simultaneous resection of primary colon cancer and liver metastases. We aimed to determine the risk factors of AL using a 10-year cohort from a nationwide database. PATIENTS AND
methodsThe American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from 2014 to 2023 was used. Patients who underwent simultaneous colectomy and liver resection were included. Multivariate analysis was performed with AL as the outcome variable. The 2:1 propensity score matching (PSM) was performed on preoperative and operative covariates.
resultsA total of 1517 patients were included. Median age was 60 years and 824 (54%) were male. Most liver resections were minor hepatectomies (87%). In total, 80 (5.3%) patients developed AL. On univariate analysis, higher ASA score, chronic steroid use, and intraoperative blood transfusion were statistically significant risk factors for AL. Multivariate analysis showed that higher ASA score (OR
conclusionsIn this study, we found that a higher ASA score, chronic steroid use, major hepatectomies, and blood transfusions were independent predictors of AL. In matched cohorts, there was also an increased risk for AL. Thus, for high-risk patient populations undergoing simultaneous resection of primary colon cancer and liver metastasis, consideration should be given for fecal diversion or staged procedures.
