Clinical experience of the attending doctor matters: diagnosing anastomotic leakage after colorectal surgery.
Article in Surgical endoscopy, 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
backgroundClinical assessment is vital in surgical decision-making, and clinical experience is thought to enhance diagnostic judgment. However, the impact of clinical experience on postoperative assessments in surgical care remains unclear. This is particularly critical for timely diagnosing anastomotic leakage after colorectal surgery, where delayed recognition can have severe consequences. This study evaluates to what extent the level of clinician experience influences the accuracy of clinical assessments in diagnosing anastomotic leakage.
methodsIn this prospective multicenter study, clinicians daily estimated the probability (0-100) of anastomotic leakage following colorectal surgery for every patient between 2013 and 2019 in two large teaching hospitals in The Netherlands. Assessors were grouped by experience level as junior doctors and colorectal surgeons. Diagnostic accuracy per group was evaluated via Receiver Operating Characteristics (ROC) analysis, and calibration was assessed using a calibration plot. Missing data were imputed through multiple imputation.
results127 (9.5%) of 1336 patients developed anastomotic leakage. The area under the curve for the clinical assessment for anastomotic leakage by junior doctors was 0.87 (95% CI 0.82-0.92) as compared to 0.95 (95% CI 0.91-0.99) for colorectal surgeons (p = 0.02). Surgeons appeared to demonstrate superior calibration compared to junior doctors.
conclusionClinical experience enhances the accuracy of clinical assessments in diagnosing anastomotic leakage after colorectal surgery. These findings underscore the importance of involving senior clinicians in postoperative care and highlight the need for targeted training of junior doctors.
