Factors affecting the risk of conversion from laparoscopy to open surgery in xanthogranulomatous cholecystitis: a retrospective cohort study.
Article in BMC surgery, 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
backgroundXanthogranulomatous cholecystitis is a rare benign pathology that can mimic gallbladder cancer. Due to inflammation-related adhesions in the gallbladder, cholecystectomy can be particularly challenging in these patients, and the conversion rates from laparoscopy to open surgery are significantly higher than normal. This study aimed to evaluate the factors influencing conversion rates in cases of xanthogranulomatous cholecystitis.
methodsPatients who underwent cholecystectomy and were pathologically diagnosed with xanthogranulomatous cholecystitis between 2018 and 2024 were included in the study. Patients were categorized into two groups: those who underwent laparoscopic cholecystectomy and those requiring conversion to open surgery. Demographic, clinical, biochemical, and radiological data were analyzed.
resultsA total of 46 patients were evaluated. The median age was 56 years (range: 29-80), and 23 patients (50%) were female. Conversion to open surgery was required in 18 patients (39.2%). In univariate analysis, a history of prior ERCP (p = 0.004), increased gallbladder wall thickness (p = 0.004), and an enlarged common bile duct diameter (p = 0.032) were associated with a higher risk of conversion. Multivariate analysis identified prior ERCP (Odds Ratio [OR]: 24.48, 95% Confidence Interval [95%-CI]: 2.25-265.95, p = 0.009) and increased gallbladder wall thickness (OR: 5.94, 95%-CI: 1.31-26.89, p = 0.021) as independent risk factors for conversion.
conclusionThe conversion rate from laparoscopy to open surgery is considerably high in cases of xanthogranulomatous cholecystitis compared to other etiologies. The risk is even greater in patients with a history of ERCP and increased gallbladder wall thickness.
