Gallbladder adenomyomatosis (GA) is a benign alteration of the gallbladder wall that can be found in up to 9% of patients. GA is characterized by a gallbladder wall thickening containing small bile-filled cystic spaces (i.e., the Rokitansky-Aschoff sinuses, RAS). The bile contained in RAS may undergo a progressive concentration process leading to crystal precipitation and calcification developm...
The course of acalculous adenomyomatosis of the gallbladder in six patients is described. It is suggested that, even in the absence of gallstones, cholecystectomy should be advised when this condition is demonstrated radiographically in symptomatic subjects. The cause of the pain is unknown but it is probably related to excessive neuromuscular activity of the hyperplastic gallbladder wall. One ...
Although infrequent, gallbladder injury occurs in approximately 2% of blunt abdominal trauma cases, which are most commonly caused by motor vehicle accidents. Furthermore, isolated gallbladder injury, including gallbladder perforation, is even more rare. A 39 year-old male patient fell down accidentally from a height of 3 m and was sustained injuries, causing right upper quadrant pain and lacer...
Histamine is an inflammatory mediator present in mast cells, which are abundant in the wall of the gallbladder. We examined the electrical properties of gallbladder smooth muscle and nerve associated with histamine-induced changes in gallbladder tone. Recordings were made from gallbladder smooth muscle and neurons, and responses to histamine and receptor subtype-specific compounds were tested. ...
The muscle and epithelial tissues of the gallbladder are regulated by a ganglionated plexus that lies within the wall of the organ. Although these ganglia are derived from the same set of precursor neural crest cells that colonize the gut, they exhibit structural, neurochemical and physiological characteristics that are distinct from the myenteric and submucous plexuses of the enteric nervous s...
Endoscopic transpapillary gallbladder stenting is currently indicated to treat acute cholecystitis, and a double-pigtail plastic stent is usually placed [1–3]. No case of cholecystocolonic fistula caused by endoscopic transpapillary gallbladder stenting has been reported. An 87-year-old man was admitted to our hospital for the treatment of right hypochondralgia. Computed tomography revealed gal...
In our study the VCC technique has been used to observe changes in the arrangement of the blood vessels in the wall of the gallbladder and urinary bladder in pig, which undergoes a variable change in the volume during their cyclical filling of urine or bile. The changes in the angioarchitecture of the gallbladder and urinary bladder has been describe in a few species of laboratory animals, but ...
BACKGROUND Gallbladder mucocele (GBM) is an increasingly recognized extrahepatic biliary disease in dogs. OBJECTIVES To investigate cases of GBM and identify variables associated with survival and the sensitivity and specificity of ultrasonography to identify gallbladder rupture. ANIMALS Two hundred and nineteen client-owned dogs with GBM. METHODS Multicenter, retrospective study of dogs ...
The objective was to develop a score, to stratify patients with acute cholecystitis into high, intermediate, or low probability of gangrenous cholecystitis. The probability of gangrenous cholecystitis (score) was derived from a logistic regression of a clinical and pathological review of 245 patients undergoing urgent cholecystectomy. Sixty-eight patients had gangrenous inflammation, 132 acute,...
A 58-year-old man with a history of Crohn’s disease (A2L2B1p), bile stones, migraine, and chronic depression presented with an 11-kg weight loss and asthenia during the preceding 6 months. He was receiving treatment with infliximab, azathioprine, mirtazapine, and lorazepam. Laboratory tests showed a slightly elevated C-reactive protein (CRP) of 35mg/dL. He underwent a computed tomography (CT) s...
