Article Abstract
Background: The prevalence of dengue fever (DF), a mosquito-borne viral disease, is rising worldwide. Its severe manifestations like thrombocytopenia and plasma leakage are associated with increased mortality. Ultrasound-detected gallbladder wall thickening (GBWT) has been suggested as a potential indicator of the severity of the disease.
Aims: This systematic review and meta-analysis evaluated the predictive value of GBWT in identifying patients at risk for severe dengue.
Methods: Following the PRISMA 2020 guidelines, we conducted a systematic search of Web of Science, PubMed, Embase, and Scopus. Among the inclusion criteria were original studies that assessed GBWT across various dengue severity categories. Then, we performed a meta-analysis using a random effects model and subgroup analyses based on severity criteria to determine the relationship between GBWT and severe dengue.
Results: For the meta-analysis, 19 studies qualified for the inclusion criteria. There was a significant association between GBWT and severe dengue, according to the odds ratio (OR) of 2.35 (95% CI 1.88-2.82, p < 0.001). The subgroup analysis revealed consistent results for thrombocytopenia (OR: 2.65) and plasma leakage (OR: 2.26), among other severity criteria.
Conclusions: A reliable ultrasound indicator, GBWT can help identify patients at risk for severe dengue early on, improving clinical decision-making and patient outcomes. However, the possibility of differential diagnosis requires cautious interpretation.

Background: Subtotal cholecystectomy (SC) is a bailout strategy for difficult gallbladders in which standard dissection may pose high risk of bile duct injury (BDI). However, concerns remain about postoperative complications.
Methods: This retrospective, observational study included 347 patients who underwent SC between February 2015 and September 2023 at a high-volume hepatobiliary center.

Objectives: To determine the clinicopathological features and prevalence of Eosinophilic cholecystitis (EC) with a single-center experience. Eosinophilic cholecystitis is an exceedingly uncommon pathologic issue caused by examining cholecystectomy specimens.
Methods: A retrospective analysis was performed on 8,342 cholecystectomy specimens.

Typical gallstone ileus includes small intestine obstruction caused by the gallstone passing from the gallbladder through the common bile duct (CBD). The case of gallstone ileus with simultaneous obstructive jaundice and intestinal ischemia is an extremely rare scenario. Computed tomography of the abdomen and pelvis is the method of choice for the diagnosis.

Acute acalculous cholecystitis [AAC] is the most common cause of acute cholecystitis [AC] in the pediatric population. Although typically found in critically ill adult patients, previously healthy pediatric patients with AAC often present in the setting of underlying infection. Upon extensive review of the literature, [Mycoplasma] was only responsible for 9 reported cases of AAC.

Background And Objective: Gallbladder diseases present a critical challenge and can cause serious complications, if not diagnosed and treated promptly. Diseases including gallstone, inflammation, and other abnormalities may lead to a number of significant consequences, such as bile duct obstructions, chronic pain, infections, and in severe cases, life-threatening sepsis or gallbladder cancer.
Methods: This study presents a novel deep learning-based diagnostic model using an attention-guided residual convolutional neural network to classify nine distinct gallbladder diseases, including gallstones, abdomen and retroperitoneal pathology, cholecystitis, membranous and gangrenous cholecystitis, perforation, polyps and cholesterol crystals, adenomyomatosis, carcinoma, and various causes of gallbladder wall thickening.
