Hidden signals in the gallbladder: a clinicopathological deep dive into 148 polyps among 11,108 surgeries.
Article in Langenbeck's archives of 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
BACKGROUND/
aimGallbladder polyps (GBPs) are increasingly detected during imaging and often identified incidentally in cholecystectomy specimens. However, management strategies vary, particularly for small, asymptomatic polyps. This study aimed to determine the prevalence, types, and malignant potential of GBPs through pathological examination of cholecystectomy specimens.
methodsWe retrospectively reviewed 11,108 cholecystectomies performed from January 2014 to January 2024. Histopathologically confirmed GBPs were identified in 148 patients. Data on demographics, comorbidities, imaging, surgical approach, and polyp features were analyzed.
resultsOf 148 patients with GBPs, 77% were female and the median age was 48 years. Hypertension (31.8%) and diabetes (16.9%) were common comorbidities. Preoperative ultrasonography detected polyps in only 33.8% of cases. Most polyps (81.8%) were pedunculated and ≤ 10 mm. Cholesterol polyps accounted for 64.2%, and precancerous/malignant lesions for 19.6%. Multivariable analysis showed sessile morphology (OR: 4.2, p = 0.001) and size ≥ 10 mm (OR: 3.8, p = 0.004) were significantly associated with malignancy.
conclusionWhile most GBPs are benign, a significant proportion carry malignant potential, particularly sessile polyps ≥ 10 mm. Improved risk stratification based on morphology and size is essential to guide management. Development of standardized follow-up protocols and refinement of imaging criteria are warranted.
