Rates and predictors of repeat preoperative endoscopy for elective colorectal resections: how can we avoid repeated procedures?
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundDespite limited endoscopy resources, repeat endoscopy prior to surgery is commonly practised. Our aim was to determine repeat preoperative endoscopy rates and factors influencing this practice at a high-volume Canadian tertiary centre.
methodA retrospective cohort study was conducted on all patients undergoing elective colorectal resections for benign and malignant neoplasms at a tertiary centre in Winnipeg, Canada between 2007 and 2017. Multivariable logistic regression analysis was used to identify predictors of repeat preoperative endoscopy.
resultsOf 1062 patients identified, mean age was 68 years and 56% were male. Rate of repeat preoperative endoscopy was 29%. On multivariable analysis, male sex (OR 1.68, CI 1.19-2.34, p = 0.003) and lesions located in the left colon (OR 2.73, CI 1.79-4.14, p < 0.001), rectosigmoid (OR 9.11, CI 2.14-38.8, p = 0.003), and rectum (OR 4.06, CI 2.58-6.38, p < 0.001) were at increased odds of undergoing repeat preoperative endoscopy. Patients with a tattoo placed at index endoscopy were at markedly lower odds of undergoing repeat preoperative endoscopy (OR 0.48, CI 0.34-0.68, p < 0.001). Index endoscopist specialty was not a significant predictor of repeat endoscopy (OR 0.76, CI 0.54-1.06, p = 0.09).
conclusionsRepeat preoperative lower endoscopy is commonly practised and may be unnecessary if appropriate identification and documentation of lesions has been achieved. Tattooing of suspicious lesions is a key modifiable factor associated with reduced likelihood of repeat preoperative endoscopy. This study highlights the need for standardized guidelines and endoscopy reporting practices given the delays and costs associated with repeat preoperative endoscopy.
