Frequency of Gallbladder Carcinoma in Patients Operated for Symptomatic Cholelithiasis.

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 Gallbladder carcinoma (GBC) is a rare but highly aggressive malignancy, often discovered incidentally during cholecystectomy for symptomatic cholelithiasis. Despite significant geographic variation, the association between gallstones and GBC is well-documented, with chronic inflammation from gallstones potentially contributing to carcinogenesis. Objective This study aims to determine the prevalence of incidental GBC in patients undergoing cholecystectomy for symptomatic cholelithiasis at a tertiary care hospital in Peshawar, Pakistan. Materials and methods This retrospective cohort study was conducted at the General Surgery Department, Hayatabad Medical Complex, Peshawar, from February 2, 2021, to July 1, 2024. A total of 230 patients, aged 18-55 years and diagnosed with symptomatic cholelithiasis, were included. Cholecystectomy was performed, and all excised gallbladders were histopathologically examined for carcinoma. Statistical analysis was conducted using IBM SPSS (version 26), with a significance threshold of p ≤ 0.05. Results Out of 230 patients, 7 (3.04%) were found to have incidental GBC upon histopathological examination. Among these, five had adenocarcinoma, and two had papillary carcinoma. The carcinoma was confined to the mucosa (T1a) in four cases, while three cases had deeper invasion (T1b). Patients with incidental carcinoma had a significantly longer symptom duration (mean: 14.2 ± 3.1 months) and were older on average (mean age: 49.2 ± 4.3 years) compared to non-carcinoma patients (p = 0.001 and p = 0.002, respectively). No malignancy was suspected intraoperatively in any case. Conclusion Incidental GBC was present in 3.04% of patients undergoing cholecystectomy for symptomatic cholelithiasis, with longer symptom duration and older age as significant risk factors. The findings underscore the importance of histopathological examination of cholecystectomy specimens in regions with high gallstone prevalence, as early detection of incidental carcinoma can facilitate timely oncological intervention.
