Background: [corrected] The present study focused on cholecystectomized elderly patients and aimed to investigate whether inflammation in the gallbladder wall was associated with the number and size of gallstones, as well as the patients' age.
Patients And Methods: The present study included 306 cholecystectomized patients aged over 65 years. From the specimens derived from cholecystectomy, the gallstone number, the largest gallstone diameter and gallbladder wall thickness were determined. According to the histopathological examination, chronic inflammation was subdivided into mild-moderate and severe. Univariable analysis and multivariable logistic regression followed.
Results: Mild-moderate inflammation characterized 63.4% of the cases and severe inflammation 366%. Solitary gallstones were found in 13.1% of the cases, while multiple gallstones were found in 86.9% of the cases. The largest gallstone diameter was less than 1 cm in the majority of cases (73.2%). The gallbladder wall thickness was associated with the degree of inflammation (p < 0.001, Chi-square). In the univariable analysis, inflammation was positively associated with the diameter of the largest gallstone (p = 0.032, Chi-square), but negatively associated with the number of gallstones (p < 0.001, Chi-square) and patients' age (p = 0.008, logistic regression). The number of gallstones was negatively associated with the diameter of gallstones and positively associated with the patients' age. The diameter of the largest gallstone was negatively associated with the patients' age. In the multivariable logistic regression, the effect of age (OR = 0.95, 95% CI: 0.91-0.99) and solitary gallstones (OR = 2.66, 95% CI: 1.02-6.93) on inflammation persisted, but that of the largest gallstone diameter vanished.
Conclusion: The elderly population presented mainly with multiple and small gallstones. Solitary gallstones and younger age were the most important predictors for severe inflammation.

: Bouveret syndrome, a rare and often underdiagnosed variant of gallstone ileus, is characterized by the presence of a large gallstone impacted in the proximal duodenum, resulting in significant gastric outlet obstruction and aerobilia. Early identification of Bouveret syndrome is crucial for developing an appropriate surgical strategy. : A 76-year-old female underwent a contrast-enhanced abdominal CT scan, which revealed a cholecysto-duodenal fistula with a 3.

Article Synopsis
- India has a high rate of gallstone incidence, which can lead to chronic inflammation and increase cancer risks; this study investigated gallstone age and composition using advanced dating and analysis methods.
- Three cholesterol gallstones with different histopathologies were analyzed, revealing that the stone with dysplasia formed over six years, while the others took longer; all stones were primarily cholesterol-based, with additional compounds found in the dysplastic stone.
- The study highlighted the potential of combining radiocarbon dating and microbial analysis in understanding gallstone development, suggesting a link between specific bacterial abundance and gallstone pathology, particularly in dysplastic cases.

Background/aims: Urgent endoscopic removal is required for gallstones impacted at the duodenal papilla. This study compared the clinical features of impacted papillary stones (IPS) with those of common bile duct stones without impaction.
Methods: This study analyzed a common bile duct stone database from 2017 to 2023, identifying patients with IPS.

Background: Early laparoscopic cholecystectomy (ELC) in the setting of acute calculous cholecystitis (ACC) requires to be performed by highly-skilled surgeons to avoid complications. The purpose of this study is to identify preoperative factors that would predict difficult ELC among patients with ACC prior to proceeding with surgery.
Methods: We retrospectively reviewed all patients who received ELC within 10 days from the onset of symptoms of ACC between August 1, 2018, and December 31, 2022.
