80-year-old female presented with clinical findings suggestive of acute cholecystitis. Intraoperatively we discovered a dusky gallbladder with gangrenous patches and gallbladder torsion with 270 degrees clockwise rotation along the longitudinal axis. Gallbladder torsion is a rare cause of acute cholecystitis with less than 500 cases published in the literature. Gallbladder torsion should be inc...

BACKGROUND The ablation of liver tumors located close to the gallbladder is likely to lead to complications. The aim of this article is to compare the safety and efficacy of irreversible electroporation (IRE) and cryoablation in rabbit livers at a location close to the gallbladder. MATERIALS AND METHODS We performed cryoablation (n = 12) and IRE (n = 12) of the area of the liver close to the ...

Multiseptate gallbladder, a rare congenital anomaly, can present with recurrent abdominal pain. Ultrasonography is the preferred imaging technique in patients with abdominal pain, especially for the evaluation of the gallbladder. We present the sonographic appearance of a multiseptate gallbladder.

Villous adenomas occur most frequently in the rectum and colon. These tumors are rarely seen in the gallbladder. We report a case of gallbladder villous adenomas in a 69-year-old patient who has systemic lupus erythematosus (SLE). The patient was admitted for investigation of a gallbladder mass. Ultrasonography, computed tomography, and magnetic resonance imaging showed two well-circumscribed l...

Agenesis of the gallbladder, a rare anomaly, is generally regarded as an organogenic failure. Several reports suggest that this congenital defect is inherited but that supposition remains controversial. We described agenesis of the gallbladder in identical twins. A 21-year-old female presented with a history of acute pain in the epigastrium and right hypochondrium. Various imaging modalities sh...

We describe a case of actinomycosis of the gallbladder mimicking carcinoma. Sonography showed a hypoechoic mass replacing gallbladder lumen and engulfing a stone; contrast-enhanced computed tomography showed a heterogeneously enhanced thickened gallbladder wall with subtle, disrupted luminal surface enhancement, which formed a mass. As a result of the clinical and radiologic presentation, our i...

AIM To determine gallbladder edema with type of Dengue infection and hematocrit level. METHODS A retrospective study was performed on 225 cases of DHF admitted from January to December 1997 to determine the association between the type of Dengue infection, hemoconcentration and the presence or absence of gallbladder edema. Primary or secondary types of Dengue infection consider to determine t...

Since impaired gallbladder emptying contributes to gallstone formation, the evaluation of gallbladder motility requires accurate methodology. Recently developed 3-dimensional ultrasonography may take into account various gallbladder shapes more accurately than conventional 2-dimensional ultrasonography. Therefore, volumes of water-filled balloons of various sizes were determined in vitro by 2-d...

The macrolide fungicide rapamycin has shown significant antiproliferative action toward a variety of tumor types. In this study, we used BK5.erbB2 transgenic mice as an animal model to examine the therapeutic effect of rapamycin as a potential treatment for gallbladder cancer. Homozygous BK5.erbB2 mice overexpressing the wild-type rat erbB2 gene in basal epithelial cells of the gallbladder have...

BACKGROUND Acute cholecystitis is a common condition in gallbladder motility disorder. Interstitial Cajal-like cells (ICLCs) in the gallbladder are known as one of the players in the complex motility mechanisms affecting gallbladder motility. AIM This study explored morphological symptoms and molecular mechanisms underlying gallbladder ICLC changes induced by acute cholecystitis. MATERIALS ...
